Editor’s Note: We cannot have infinite growth on a finite planet. Something that should be a part of common sense is somehow lost in meaning among policymakers. In this piece, Elisabeth Robson explains the concept of overshoot to explain just that. She also delves into how the major policy makers have ignored it in favor of focusing on climate change and proposing “solutions” of renewable energy. Finally, she ends with three presentations on the same topic.
Bill Rees spent a good part of his career developing a tool called the ecological footprint analysis — a measurement of our collective footprint in terms of the natural resources humans use each year and the waste products we put back into the environment. His analysis showed that humanity is well into overshoot — meaning, we are using far more resources than can be regenerated by Earth, and producing far more waste than the Earth can assimilate.
Overshoot is like having a checking account and a savings account and using not only all the money in our checking account each year, but also drawing down our savings account. Everyone knows if we spend down our savings account, eventually we’ll run out of money. In ecological terms, eventually we’ll run out of easily-extractable resources and do so much damage from the pollution we’ve created, life-as-we-know-it will cease to exist.
I don’t like using the word “resources” to describe the natural world, but it is a handy word to describe all the stuff we humans use from the natural world to keep ourselves alive and to maintain industrial civilization: whether that’s oil, trees, water, broccoli, cows, lithium, phosphorus, or the countless other materials and living beings we kill, extract, process, refine, and consume to get through each and every day and keep the global economy humming. Please know that I wince each time I write “resources” to represent living beings, ecosystems, and natural communities.
Whatever we call the stuff that fuels 8+ billion humans and the great big hungry beast that is industrial civilization, Bill’s analysis estimates our collective ecological footprint is currently running at about 1.75 Earth’s worth of it. Of course that use is unevenly distributed; as a North American, I am ashamed to say that I and my many neighbors on this continent have an ecological footprint 15–20 times bigger than the Earth could sustain if everyone lived like us. Many people on Earth still have ecological footprints far below what the Earth could sustain if everyone lived like them, so it all averages out to 1.75 Earths.
But wait! you might be saying; how can we be using more than one Earth’s worth of resources? Because we are drawing down those resources, like drawing down our savings account. Each year less is regenerated — fewer salmon and fewer trees for instance — more materials are gone forever, more toxic waste is polluting the environment. Eventually the savings account will be empty, and that’s when life-as-we-know-it ends for good.
A companion yardstick for measuring human overshoot of Earth’s carrying capacity is the planetary boundaries framework. This framework identifies nine processes that are critical for maintaining the stability and resilience of the Earth system as a whole. The framework tracks by how much we’ve transgressed beyond a safe operating space for the nine processes: climate change, biosphere integrity, land system change, freshwater change, biogeochemical flows, ocean acidification, atmospheric aerosol loading, stratospheric ozone depletion, and novel entities such as micro plastics, endocrine disruptors, and organic pollutants.

Six of the nine boundaries are transgressed, and of those, five are in the high risk zone. By far the boundary we’ve transgressed furthest is biosphere integrity — much more so than climate change. This is perhaps not surprising given that humans and our livestock make up 96% of the weight of land mammals and wildlife a mere 4%, and that the accumulated weight of all human stuff on the planet now weighs more than all living beings — flora and fauna combined — on Earth.
I’m writing this as the UN Framework Convention on Climate Change (UNFCCC) Conference of Parties (COP) 28 is wrapping up in Dubai, UAE. There was a lot of talk about climate change and fossil fuels — mostly whether we will “phase down” or “phase out” our use of fossil fuels — and about so-called “renewables.” The conference ended with a global goal to “triple renewables and double energy efficiency.”
“We acted, we delivered,” claimed COP28 President Sultan Al Jaber, as if building more industrial technologies, like wind turbines and solar panels, and making more energy efficient buildings and cars will somehow restore biosphere integrity; unpollute the water, land and air; regrow all the old-growth forests; unpave the wetlands; and reverse the 1000x-faster-than-normal rate we exterminating species on Earth.
The global focus on climate change, cemented by almost 30 years of UNFCCC conferences, has blinded the world to our true predicament — that is, ecological overshoot — of which climate change is just one of many symptoms. Organizations, governments, corporations, the media are all talking and talking about climate change and the supposed “solutions” of renewables and energy efficiency, while essentially ignoring the ongoing destruction of the natural world. I sometimes imagine them sitting around the large conference tables at the COP with their fingers in their ears singing la-la-la-la-la so as to tune out the natural world as she begs for mercy while they plan “green growth” and scheme to make sure none of the agreements will put a dent in any of their bank accounts.
Likewise, local governments, including the one where I live, are also entirely focused on climate change. Recent meetings, reports, policies, and plans in the county where I live reflect the carbon tunnel vision that is legislated from on high, including state laws mandating net zero greenhouse gas emissions by 2050 and “clean electricity” by 2045, and enforcing a market-based program to cap greenhouse gas emissions.
These state laws and others, as well as federal incentives such as the Infrastructure Law of 2021 and the Inflation Reduction Act of 2022, put the focus squarely on carbon emissions. No other symptom of ecological overshoot has such clear cut, goal-oriented legislation as carbon emissions.
Carbon tunnel vision
Carbon tunnel vision means other problems get short shrift. And the “solutions” that corporations are selling us in order to meet the goals set by federal and state law will actually make many of the other symptoms of ecological overshoot worse. Far worse.
Imagine the hockey-stick shaped graph of growth over the past 250 years or so. It doesn’t really matter what growth you’re measuring — population, the economy, average income, fertilizer use, nitrogen runoff, copper extraction— that graph is going steeply up.
The Great Acceleration
My county’s planning documents assume that growth line will continue going up. Everywhere’s planning documents assume the same — that the economy, population, extraction, development, and consumption will continue growing. Indeed, an economy based on debt requires it for life-as-we-know-it to continue.
But this is simply not possible on a finite planet with finite resources and ecosystems already shattering under pressure. Basic laws of ecology tell us that when a species overshoots the regenerative capacity of its environment, that species will collapse. This is true for humans too. Our city, county, state, and federal policies do not reflect this reality in any way. This is shortsighted at best; a catastrophe at worst.
So why are most scientists, organizations, and governments so focused on climate change and carbon emissions? In part, because it’s relatively easy to measure. We’ve been measuring carbon dioxide in the atmosphere since 1958, and many other greenhouse gases almost as long. We can see the average annual parts per million increase every year. It’s much easier to measure CO2 ppm in the atmosphere than it is to count every last frog of a given species, or detect toxic pollutants in ground water, or track the decline of top soil, or do long term studies on the impacts of pesticides and herbicides.
Another answer to that question is that corporations have created technologies and industries they can sell to the world as “solutions” to climate change. These “solutions” allow corporations and the governments they influence to believe we can continue business-as-usual. The pervasive propaganda about these “solutions” allows us regular folk to believe we can continue life-as-we-know-it without having to worry too much because “someone’s doing something about climate change.”
Unlike the “solutions” to climate change that corporations are constantly trying to sell us, there is no profitable technology that will eliminate habitat loss, species extinctions, pollution, and deforestation. And so what we hear from organizations, governments, corporations, and the media is all climate change all the time, because someone’s making bank.
To try to break through the wall of all climate change all the time, I recently hosted a series of events on ecological overshoot. I invited everyone I could think of in my county who might have influence on county policy and planning in hopes of sparking the kinds of broader conversations I wish we were having. Few of those people showed up, perhaps unsurprisingly, so it seems unlikely those conversations will happen.
However, the three presentations — by Bill Rees, Jeremy Jiménez, and Max Wilbert — are excellent and well worth sharing with the broader community of people who are trying their best to start conversations about ecological overshoot.
I hope you enjoy these presentations as much as I did, and have better luck than I have at broaching these topics with people where you live.
Editor’s note: As we see in this article, published on 10/24/2023 by Investigate Europe you can find on their website www.investigate-europe.eu, the European Union abandons it’s own environmental standards when it comes to pursuing geopolitical interests in remote places.
In July of 2023 the European Parliament voted for the EU restoration law so that a part of the 80 percent of natural habitats already damaged can be rewilded. But the implementation of this law can only make an impact if Europe decreases it’s use of metals and minerals from mining, outside and inside of it’s borders.
With importing “critical” metals from Russia the EU supports a war that displaces millions of people and harms wild habitats. These double standards, imposing sanctions on Moscow yet at the same time profiting off of the rich “resources” Russia provides, shows how modern societies work: governments and industries must firstly attend upon their high energy demand, ethical and environmental standards are at the bottom of the list.
Could it be the reason for this is not in spite of a defence against the attacker but because of it: The land of the enemy should be used to the benefit of the one who is in the “right” until it is drained of it’s “resources”. Like an outlawed person bereaved of rights and dignity. This dangerous attitude unfolds in front of our eyes: a competition where the living planet can only loose.

Since Russia’s invasion of Ukraine in February 2022, the 27 EU countries have adopted 11 sanction packages, targeting raw materials including oil, coal, steel and timber. But minerals that the EU considers as “critical” raw materials – 34 in total – still flow freely from Russia to Europe in vast quantities, providing crucial funds to state enterprises and oligarch-owned businesses.
While some of its western allies have targeted Russia’s mining sector – the UK recently banned Russian copper, aluminium and nickel – the EU has continued its imports. Airbus and other European companies are still buying titanium, nickel, and other commodities from firms close to the Kremlin more than a year after the invasion, Investigate Europe can reveal.
Between March 2022 and July this year, Europe imported €13.7 billion worth of critical raw materials from Russia, data from Eurostat and the EU’s Joint Research Centre shows. More than €3.7 billion arrived between January and July 2023, including €1.2 billion of nickel. The European Policy Centre estimates that up to 90 per cent of some types of nickel used in Europe comes from Russian suppliers.
“Why are critical raw materials not banned? Because they are critical, right. Let’s be honest,” the EU’s special envoy for sanctions, David O’Sullivan, pithily said at a September conference.
The Union is desperate for critical raw materials to achieve its aim of climate neutrality by 2050. These commodities are crucial for electronics, solar panels and electric cars, but also for traditional industries like aerospace and defence. Yet they are all too often in scarce supply, unevenly available across the globe, and in high demand.
“The war in Ukraine has clearly shown the willingness of Russia to weaponise the supply of key resources. As Europeans, we cannot tolerate that,” says Henrike Hahn, a German Green MEP working on the new Critical Raw Materials Act.
Europe’s imports not only fund Russia’s war economy, but also benefit Kremlin-backed oligarchs and state companies. Although the EU has targeted some shareholders, Russia’s mining businesses have faced no restrictions. The loophole is even more glaring that the US and the UK sanctioned several firms directly, further isolating the EU in its double standards.
Analysis of Russian customs data shows that Vsmpo-Avisma, the world’s largest titanium producer, sold at least $308 million of titanium into the EU via its German and UK branches between February 2022 and July 2023. It is part-owned by Russia’s national defence conglomerate, Rostec. The two companies share the same chairman: Sergei Chemezov, a close Putin ally. The pair were KGB officers in East Germany in the 1980s.
Both Chemezov and Rostec are under EU sanctions and helped supply tanks and weapons to the Russian army. Brussels has not sanctioned Vsmpo-Avisma directly, but the US did ban exports to the firm on 27 September, saying it was “directly involved in producing and manufacturing titanium and metal products for the Russian military and security services.”
Among Vsmpo-Avisma’s largest European customers is Airbus, the aerospace giant partly owned by the French, German and Spanish states. Between the start of the war and March 2023, Airbus imported at least $22.8 million worth of titanium from Russia; a fourfold increase in value and tonnes compared to the previous 13 months.
From 14 March 2023, Vsmpo-Avisma stopped identifying buyers in customs filings but nothing indicates a significant change in trends. Titanium imports to France only slightly decreased between then and July 2023, and Airbus still listed the company as a supplier in July.
“We have no comment on the details and evolution of our titanium sourcing volumes,” an Airbus spokesperson said. “Generally speaking, Airbus is currently ramping up commercial aircraft production and this is having a mechanical impact on its overall procurement volumes.” Even though it will take time, the group is reducing its dependency on Russia, the spokesperson said, adding that a ban on Russian titanium for civil aviation would “encourage the Russian industry to focus on defence needs.”
Unlike Vsmpo-Avisma, other Russian companies have avoided naming their buyers in customs filings altogether. Yet the data still gives a scale of their fruitful relationship with the west. Nornickel, the world leader in palladium and high-grade nickel, exported $7.6 billion worth of nickel and copper into the EU via Finnish and Swiss subsidiaries between the start of the war and July 2023. It also sent over $3 billion of palladium, platinum and rhodium into Zurich airport. In 2022, almost 50 per cent of Nornickel’s sales went to Europe. Brussels has not sanctioned the group nor its chairman and largest shareholder, Vladimir Potanin, an oligarch and former deputy prime minister under US and UK sanctions.
Aluminium giant Rusal also uses tax havens to funnel minerals to Europe, where it owns the EU’s largest alumina refinery in Ireland and a smelter in Sweden. Its Jersey and Swiss-based trading houses brought at least $2.6 billion of aluminium into the bloc in the 16 months following the invasion of Ukraine. In August 2023, Rusal said Europe still accounted for a third of its revenues. Rusal’s main shareholder is oligarch Oleg Deripaska, sanctioned by the EU and its western partners.
Anti-corruption NGO Transparency International says it does not make sense that the sector has avoided sanctions given the known links.
“They are part of the system and fueling Putin’s war,” says senior policy officer Roland Papp. “So it’s perfectly logical to ban those critical raw materials from Russia, as we did for other sectors and goods.”
Since the start of the war, other European buyers of Russian metals have included Germany’s GGP Metal Powder ($66 million of copper), French arms-maker Safran ($25 million of titanium) and Greece’s Elval Halcor ($13 million of aluminium). Dutch logistics firm C. Steinweg also handled at least $100 million of various critical metals on behalf of its customers.
Safran confirmed they are still buying titanium from Vsmpo-Avismo but are working to reduce their Russia purchases. GGP Metal Powder said “there is no real alternative to our supplier from Russia“. C. Steinweg said they follow all rules and sanctions. Elval Halcor, Vsmpo-Avisma, Rusal and Nornickel did not reply to requests for comment.
At the start of the war, Europe was relying on Russian producers for 30 per cent of its nickel, 35 per cent of its alumina and 15 per cent of its aluminium, according to an internal memo by trade body Eurometaux seen by IE. Russia accounted for 41 per cent of the world’s palladium production, and up to 25 per cent of its vanadium output.
“Russia occupies a large part of Eurasia – it possesses a big part of the strategic reserves of critical raw materials, on par with China,” says Oleg Savytskyi from Razom We Stand, a Ukrainian NGO. Moreover, “the low density of the population, authoritarian control and practical absence of environmental and human rights protections made investments in the mining of Russia’s resources terribly attractive,” he adds.
The EU’s crippling dependency should have been curbed earlier, argues Transparency International’s Papp. “We’ve had enough time to react. The annexation of Crimea dates back to 2014, the invasion of Georgia even dates back to 2008 15 years ago! And what have we done? We’ve increased our dependence on Russia. It was an absolute and serious mistake.”
A Polish diplomat said Poland has pressed the EU to “decouple completely” from Russia in several areas, “but for the sake of unity and efficiency in adopting new sanctions packages we have agreed to postpone particular measures until further discussion.”
As EU sanctions require unanimity among all member states, divergent national economic interests can often water down packages. When the ninth set of sanctions banned fresh investments in Russia’s mining sector in December 2022, it included an exemption to invest in some mining activities for some critical raw materials. As a result, European companies can still pour cash into Russian mines to extract nickel, titanium and other key metals.
The European Commission won’t publicly comment on whether or not it has proposed a ban on critical raw materials. One reason could be that “sanctions are carefully designed to hit their targets while preserving EU interests,“ an EU source told IE.
Weaning the EU off Russia’s critical and strategic materials will be difficult. Replacing suppliers and forging new international partnerships is an arduous process. Finding a raw material, such as titanium or copper, with a similar quality and price of those from Russia is also a challenge.
Imposing tariffs or severing ties too quickly could lead to a global price surge which would harm European buyers while benefiting Moscow. A ban could also prompt India, Iran, and China to intensify purchases, further depleting critical raw material resources for EU industries.
Tymofiy Mylovanov, president of the Kyiv School of Economics, says a ban would be difficult to implement given global demand challenges and Europe’s reliance on Russia. “Overall, with these specific materials, the monetary value of what Russia would lose from the EU import ban, might be smaller than the effect on the EU production,” says Ukraine’s former trade and economic development minister.
UN trading data shows that while EU imports of Russian copper, nickel and aluminium imports have declined in the past two years, nickel and aluminium revenues remained stable. Russia’s nickel sales to the EU were worth $1 billion in the first half of 2021 and were $1.1 billion two years later.
The Union is now trying to reduce its dependency. In March, the European Commission presented its Critical Raw Materials Act (CRMA), a new legislation aimed at reducing EU dependency on third countries for critical raw materials.
“War in Europe is a risk which was not present in the last decades and Russia was known as a reliable supplier,” says German MEP Hildegard Bentele, shadow rapporteur on the CRMA at the European Parliament. “The EU should take immediate action to support European companies to decrease and replace their CRM deliveries from Russia as soon as possible.”
The High Representative of the Union for Foreign Affairs and Security Policy is expected to propose a 12th package of sanctions in the coming weeks, which will be then discussed by member states. Brussels hopes the package will renew pressure on the Russian economy and sap its fighting strength on the battlefields of Ukraine. Restrictions on critical raw materials does not seem to be on the table.
Editor’s Note: The impact of climate change has begun to impact the financial market. Insurance companies aim to make profit on risk coverage. However, if the risk for any sector runs too high, they tend not to invest in that. Nuclear reactors are a common example. Private insurance companies do not insure nuclear reactors as the associated risks are too high. With the rapidly increasing climate change, however, insurance in even the housing market has become too costly. The article describes this phenomenon.
From California to Florida, homeowners have been facing a new climate reality: Insurance companies don’t want to cover their properties. According to a report released today, the problem will only get worse.
The nonprofit climate research firm First Street Foundation found that, while about 6.8 million properties nationwide already rely on expensive public insurance programs, that’s only a fraction of 39 million across the country that face similar conditions.
“There’s this climate insurance bubble out there,” said Jeremy Porter, the head of climate implications at First Street and a contributor to the report. “And you can quantify it.”
Each state regulates its insurance market, and some limit how much companies can raise rates in a given year. In California, for example, anything more than a 7 percent hike requires a public hearing. According to First Street, such policies have meant premiums don’t always accurately reflect risk, especially as climate change exacerbates natural disasters.
This has led companies such as Allstate, State Farm, Nationwide, and others to pull out of areas with a high threat of wildfire, floods, and storms. In the Southern California city of San Bernardino, for example, non-renewals jumped 774 percent between 2015 and 2021. When that happens, homeowners often must enroll in a government-run insurance-of-last-resort program where premiums can cost thousands of dollars more per year.
“The report shows that actuarially sound pricing is going to make it unaffordable to live in certain places as climate impacts emerge,” said David Russell, a professor of insurance and finance at California State University Northridge. He did not contribute to the report. “It’s startling and it’s very well documented.”
Russell says that what’s most likely to shock people is the economic toll on affected properties. When insurance costs soar, First Street shows, it severely undermines home values — and in some cases erodes them entirely.
The report found that insurance for the average California home could nearly quadruple if future risk is factored in, with those extra costs causing a roughly 39 percent drop in value. The situation is even worse in Florida and Louisiana, where flood insurance in Plaquemines Parish near New Orleans could go from $824 annually to $11,296 and a property could effectively become worthless.
“There’s no education to the public of what’s going on and where the risk is,” said Porter, explaining that most insurance models are proprietary. Even the Federal Emergency Management Agency doesn’t make its flood insurance pricing available to the public — homeowners must go through insurance brokers for a quote.
First Street is posting its report online, and it also runs riskfactor.com, where anyone can type in an address and receive user-friendly risk information for any property in the U.S. One metric the site provides is annualized damage for flood and wind risk. Porter said that if that number is higher than a homeowner’s current premiums, then a climate risk of some kind probably hasn’t yet been priced into the coverage.
“This would indicate that at some point this risk will get priced into their insurance costs,” he said, “and their cost of home ownership would increase along with that.”
Wildfires are the fastest growing natural disaster risk, First Street reported. Over the next 30 years, it estimates the number of acres burned will balloon from about 4 million acres per year to 9 million, and the number of structures destroyed is on track to double to 34,000 annually. Wildfires are also the predominant threat for 4.4 million of the 39 million properties that First Street identified as at risk of insurance upheaval.
“You don’t want someone to live in a place that always burns. They don’t belong there,” he said. “We’re subsidizing people to live in harm’s way.”
First Street hopes that highlighting the climate insurance bubble allows people to make better informed decisions. For homeowners, that may mean taking precautions against, say, wildfires, by replacing their roof or clearing flammable material from around their house. Policymakers, he said, could use the information to help at-risk communities adapt to or mitigate their risk. In either case, Porter said, reducing threats could help keep insurance rates from spiking.
Ultimately, though, Russell says moving people out of disaster-prone areas will likely be necessary.
“Large numbers of people will need to be relocated away from areas that will be uninsurable.” he said. “There is a reckoning on the horizon and it’s not pretty.”

Ecology of Spirit
Species extinction. Chemical pollution. Global warming. The death of the oceans.
Our planet is in crisis. And while the wealthy and governments pour trillions into technological so-called “solutions,” things are spiraling out of control.
What if solving the ecological crisis depended on decolonizing our minds and altering our very cosmology?
What if a biocentric worldview — one which places the natural forces shaping our world at the center of our morality — could help us access the courage we’ll need to stop the destruction?
On October 21st, join us for special 3-hour live streaming event: Ecology of Spirit: Biocentrism, Animism, and the Environmental Crisis. Access the event on https://www.facebook.com/events/
This event will explore issues of biocentrism with a focus on direct relationship to the spirit world and on organized political resistance to the destruction of the planet. There will be opportunities to ask questions and participate in dialogue.
The mainstream environmental movement is funded mainly by foundations which often do not support foundational or revolutionary change. Radical organizations like Deep Green Resistance therefore rely on individual donors to support our activism around the world, which is why “Ecology of Spirit” is also a fundraiser.
We’re raising funds to support global community organizing, fund mutual aid and direct action campaigns, and sustain our core outreach and organizational work.
Editor’s Note: In 2015, a study developed nine indicators for planetary health, and corresponding nine threshold or boundaries. According to a recent study based on the same framework, six of the nine boundaries have already been crossed, while the other three are in the process of being crossed. This should come as a surprise to very few. The interesting fact about this new framework is that climate change is only one of the nine indicators in the new model, which is unlike in the mainstream environmental movement belief. This framework gives a much more holistic picture of the current ecological crisis than is common among the wider culture.
Scientists behind a new study on the crossing of the Earth’s “planetary boundaries” on Wednesday likened the planet to a sick patient, warning that six out of nine barriers that ensure the Earth is a “safe operating space for humanity” have now been breached.
Researchers at the University of Copenhagen, the Potsdam Institute for Climate Impact Research (PIK), and other international institutions analyzed 2,000 studies to update a planetary boundary framework developed in 2009 by the Stockholm Resilience Center, completing the first “complete check-up of all nine processes and systems that determine the stability and resilience of the planet.”
The boundaries for climate change and land use have been broken for decades as extractive industries have razed forests and planet-heating fossil fuel emissions have significantly increased since preindustrial times.
The “novel entities” boundary—pertaining to the accumulation of synthetic pollution from substances such as microplastics, pesticides, and nuclear waste—was quantified for the first time in the study, which was published in Science Advances.
Freshwater change—both “green” freshwater in soil and vegetation and “blue” freshwater in bodies of water—has also been breached, along with biogeochemical flows, or the flow of nitrogen and phosphorus into the environment, which can create ocean dead zones and algal blooms.
“We don’t know how long we can keep breaching these key boundaries before combined pressures lead to irreversible change and harm.”
The study marked the first time researchers quantified a control variable for the “biosphere integrity” boundary, which they found was breached long before the framework was introduced—in the late 19th century as the Industrial Revolution and other factors accelerated the destruction of the natural world.
Co-author Wolfgang Lucht called biosphere integrity “the second pillar of stability for our planet” next to climate change, and warned the pillar is being destabilized by humans “taking out too much biomass, destroying too much habitat, deforesting too much land. Our research shows that mitigating global warming and saving a functional biosphere for the future should go hand in hand.”
“This update on planetary boundaries clearly depicts a patient that is unwell, as pressure on the planet increases and vital boundaries are being transgressed,” said Johan Rockström, director of PIK. “We don’t know how long we can keep breaching these key boundaries before combined pressures lead to irreversible change and harm.”
The boundaries for atmospheric aerosol loading, or air pollution, and ocean acidification, are both close to being crossed, while the atmospheric ozone boundary is currently well below the “zone of increasing risk,” due to global initiatives within the Montreal Protocol, adopted in 1987.
The fact that the boundary for ozone depletion was once “headed for increasing regional transgressions” and slowly recovered, said co-author Katherine Richardson of the University of Copenhagen, shows that it is possible to bring the planet back from the boundaries that it’s close to crossing or that have been breached to a lesser degree, such as freshwater change.
“We can think of Earth as a human body, and the planetary boundaries as blood pressure,” said Richardson. “Over 120/80 does not indicate a certain heart attack but it does raise the risk and, therefore, we work to reduce blood pressure.”
The boundaries that have reached the highest risk level are biosphere integrity, climate change, novel entities, and biogeochemical flows.
The update to the framework “may serve as a renewed wake-up call to humankind that Earth is in danger of leaving its Holocene-like state,” reads the study, referring to relatively stable state the planet was in between the end of the last ice age—10,000 years ago—until the start of the Industrial Revolution.
The study, said global grassroots climate action campaign Extinction Rebellion, offered the latest evidence that policymakers must do everything in their power to “just stop oil”—ending approval for fossil fuel projects, subsidies for oil and gas companies, and policies that slow down a transition to renewable energy.
“We are not separate from the Earth,” said the group. “We ignore these warnings at our peril.”
Event alert: Planet Local Summit
Local futures is organizing its biggest and boldest event ever – the Planet Local Summit – which is set to begin this Friday! We are excited and honoured to welcome participants from 50 countries (and counting) to our livestream, along with our in-person audience in Bristol, UK.
If you haven’t already registered, there’s still time to book your attendance online and join like-minded localization community representatives from every corner of the earth.
In Bristol, the excitement is building, with a huge mural celebrating the Planet Local Summit unveiled in the city last week. Created by iconic local artists Silent Hobo and Inkie, the colorful 600 ft mural (pictured above) has been unveiled at the Tobacco Factory – Bristol’s biggest and most famous street art wall.
Local groups have also organized 10 pre-summit events to highlight the best of Bristol, including farm open days, community dialogues, and food tours.
Editor’s Note; The fossil fuel industry is largely responsible for the climate crisis we are in today. The following article highlights the current state of the climate crisis.
While we believe that the fossil fuel industry needs to be stopped, DGR does not believe that “green” energy is going to save the planet. We believe that the green energy industry is just an extension of the ‘traditional” energy industry, running with the same disregard for the natural world.
This article was produced by Earth | Food | Life, a project of the Independent Media Institute.
You may remember the 2004 disaster movie The Day After Tomorrow, in which large parts of Europe and the American East Coast suddenly freeze up?
The plot device is that the Great Conveyor Belt—also known as the Atlantic Meridional Overturning Circulation (AMOC)—which brings heat from the south Pacific around the southern tip of Africa and up the east coast of the Americas (we call it the Gulf Stream) into the North Atlantic and Europe shuts down.
The AMOC and the heat it brings to the North Atlantic ocean is the main reason why London (at the same latitude as Calgary) has a relatively temperate climate year-round, instead of being snowbound six months out of the year.
It’s why Europe can grow enough food to feed its 740+ million people; if the AMOC was to stop transporting all that heat to the North Atlantic, the continent could be plunged into famine in a matter of years or decades (the movie was heavily dramatized).
The IPCC has warned of this possibility but had placed the danger zone for the failure of the AMOC in the early 22nd century, well past the lifetimes of most people living today. That proclamation moved it off most of our immediate-attention screens.
Now, however, might be a good time to watch the movie again: a new study published in Nature Communications last week titled “Warning of a Forthcoming Collapse of the Atlantic Meridional Overturning Circulation” reports that global warming forced by all the CO2 and methane in our atmosphere—if we don’t do something immediately—could shut down the AMOC as early as 2025 and almost certainly before 2095.
This adds to a growing body of alarming climate science, like the one published last year in the Journal of Climatetitled “Sixfold Increase in Historical Northern Hemisphere Concurrent Large Heatwaves Driven by Warming and Changing Atmospheric Circulations,” which indicates we’re much farther down the path of dangerous climate change than even most scientists realized.
That study essentially predicted this year’s shocking Northern Hemisphere heat waves (with more and worse to come); the lead researcher’s first name is Cassandra, no doubt an unintentional choice in the paper’s authors’ pecking order, but still.
It brings up the topic of the “Clathrate Gun Hypothesis,” which is the absolute worst case scenario for humanity’s future.
All across the planet there are an estimated 1.4 trillion tons of methane gas frozen into a snowcone-like slurry called clathrates or methane hydrates laying on the sea floor off the various continental shelves.
When they suddenly melt, that’s the “firing of the gun.” An explosion (in the context of geologic time) of atmospheric gas that’s over 70 times as potent a greenhouse gas as CO2. The Clathrate Gun.
The PNAS paper mentioned above concludes that 126,000 years ago there was an event that caused a small amount of these clathrates to warm enough to turn to gas and bubble up out of the seas. The resulting spike in greenhouse gas (methane) led to a major warming event worldwide:
“Our results identify an exceptionally large warming of the equatorial Atlantic intermediate waters and strong evidence of methane release and oxidation almost certainly due to massive methane hydrate destabilization during the early part of the penultimate warm episode (126,000 to 125,000 y ago). This major warming was caused by … a brief episode of meltwater-induced weakening of the Atlantic meridional overturning circulation (AMOC) and amplified by a warm mean climate.”
The researchers warn we may be looking at a similar event in our time:
“Our results highlight climatic feedback processes associated with the penultimate climate warming that can serve as a paleoanalog for modern ongoing warming.”
As glaciers melt and the oceans warm, they note:
“[M]eltwater-induced AMOC weakening significantly amplifies the warming of intermediate waters and, in turn, destabilizes shallow subsurface methane hydrate deposits.”
In other words, the recent extreme warming of our oceans increases the chances the AMOC Great Conveyor Belt will shut down, throwing Europe into an existential crisis and wilding the rest of the world’s weather. And, most ominously, the AMOC shutting down will speed up the melting of more methane clathrates on the sea floors around the world.
The process is driven by warming of the oceans, which absorb more than 90 percent of the additional global warming heat we’re forcing by burning fossil fuels. As the BBC noted, the past month and first weeks of July “were hotter than any in recorded history” and:
“This week, sea surface temperatures along the coasts of Southern Spain and North Africa were 2-4C (3.6-7.2F) higher than they would normally be at this time of year, with some spots 5C (9F) above the long-term average.”
Ocean temperatures off the coast of Florida this week were in the range that Jacuzzi recommends for their hot tubs: 101 degrees. This has never happened before in human history.
The least likely but most dangerous outcome scenario is that the warming ocean might begin a massive melting of those methane hydrate slurries into gas, producing a “burp” of that greenhouse gas into the atmosphere, further adding to global warming, which would then melt even more of the clathrates.
It would be a deadly “positive feedback system,” with each phase of warming setting up the next and worse one. The Clathrate Gun.
At the end of the Permian, 250 million years ago, this runaway process is apparently what happened when a spike in methane led to such a violent warming of the planet that it killed over 90 percent of all life in the oceans and 70 percent of all life on land, paving the way for the rise of the dinosaurs, as cold-blooded lizards were among the few survivors.
That period is referred to as the Permian Mass Extinction, or, simply, “The Great Dying.” It was the most destructive mass extinction event in the history of our planet.
The “clathrate gun hypothesis” is controversial, but there’s a large body of evidence for it having done the damage at the end of the Permian, as we note in that video.
While it’s the least likely but most dramatic outcome of today’s global warming, it’s worth heeding the warning: by pouring over thirty billion tons of carbon into the atmosphere every year we have stirred a beast that could—if we don’t take serious action soon—spell the doom of human civilization, if not humanity itself.
“The key findings of our study add to a growing body of observational findings strongly supporting the ‘clathrate gun hypothesis.’ … Importantly, the interval we have studied is marked by a mean climate state comparable to future projections of transient global climate warming of 1.3 °C to 3.0 °C.” [emphasis mine]
We just this year passed 1.3 degrees Celsius of planetary warming: we are now in the territory of the Clathrate Gun Hypothesis if these researchers are right (although the risks are still small).
This is the first study I’ve seen to make such a claim, and it’s not from crackpots or alarmists; these are solid, credible scientists with a lifetime of learning and work behind them.
And, they argue, if the AMOC weakens or shuts down, all bets are off:
“Simulation studies have suggested warming of intermediate waters has been limited to ∼1.5 °C to 3 °C, and that such warmings were insufficient to significantly affect the stability of shallow subsurface methane hydrates. However, the magnitude of intermediate water warming can be significantly amplified by meltwater-induced weakening of atmospheric and ocean circulation, an amplification not considered in the simulations that examined potential gas hydrate destabilization.”
In other words, if the AMOC fails, the clathrate gun hypothesis becomes significantly more viable.
For much of the past four decades, climate activists have been warning us that we’re approaching tipping points and thresholds that will alter how Americans live, cost us a fortune, and kill millions of humans every year.
Now we’re there. Our “normal” climate is dead; the weather has gone insane, and it is annually killing thousands of Americans and millions of people all around the globe. And the numbers are increasing almost exponentially, year to year.
This is how quickly it has hit us: when I published the first edition of my book warning of climate change, The Last Hours of Ancient Sunlight, in 1996 (it’s been updated twice since then) there was still a vigorous debate here in the United States—funded in large part by the fossil fuel industry and its allies in rightwing media—over whether climate change was even a real thing.
They knew that their product was poisoning our atmosphere, but they were making hundreds of billions of dollars in profits. Nothing was more important to these morbidly rich people than that money.
They and their bought-off politicians began to believe their own lies, or at least some did, and thought this wouldn’t happen until they were all dead anyway, even if it was true.
But then it happened. The climate emergency we were worried about arrived. It is here, now.
Looking at statistical information about major heatwaves—particularly ones that hit multiple continents at the same time—the authors of the Journal of Climate paper referenced above found:
“Such simultaneous heatwaves are 7 times more likely now than 40 years ago. They are also hotter and affect a larger area.”
In the 1980s the Northern Hemisphere averaged around 73 heatwaves during the summer months from May to September. By the 2010s that number had grown to 152 heatwaves per summer.
And those heat waves are also almost 20 percent hotter than they were the year Reagan won the presidency (and denied climate change throughout his 8 fossil-fuel-funded years in office).
One of the most startling understandings of what’s happening has only become apparent in the past decade or so: that the atmospheric Polar Jet Stream is acting weird and thus making our weather extremes more severe.
Over the course of multiple conversations with a few of the world’s top climate scientists I’ve learned that the Polar Jet Stream—the fast-moving river of high-altitude (30,000+ feet) air that circulates around the North Pole—has slowed down, weakened, and is beginning to “drool” down over parts of North America, going as far south as Texas.
This was, in fact, what caused the severe winter weather that shut down Texas’ privatized power grid a few years back, along with causing the “bomb cyclone” freezing storms hitting the Midwest and Northeast every winter, and the extended periods of 100+ degree weather all across America, Europe, Russia, and China this summer.
Historically, the Polar Jet Stream was held in place—mostly in the northern part of the Northern Hemisphere—by the temperature differential between the Arctic and the middle latitudes, where most Americans (outside of northern Alaska) live.
The cold arctic air defined the northernmost margin of the Polar Jet Stream while the warmer middle latitude air defined its southernmost margin. While it pushed weather patterns across North America for much of my life, it rarely dipped below the Mason-Dixon line and, even when it did, generally just brought the hot/cold, or wet/drought weather behind it for only a day or two.
But the Arctic has been warming at least three times faster than the middle latitudes where most of us live, which means the difference in temperature between the Arctic air to the north of the Jet Stream and our air to its south has diminished.
The North Pole/Arctic, once a solid cap of ice where Santa Claus was supposed to live, is now an open sea every summer.
As that temperature differential has declined, so has the strength and velocity of the Jet Stream. Now, instead of whipping across the Northern Hemisphere, it often spills down as far south as Mexico and then stays in place for days at a time.
What would have been a one-day cold-snap or heat wave becomes multiple days, long enough to wreak billions in damage to a state’s residential and energy infrastructure.
What would have been a rainstorm lasting a few hours becomes an unrelenting downpour lasting for days, creating massive flooding.
These changes in the Jet Stream, combined with the warming of our oceans (whose temperatures also drive weather), have also caused what were once routine weather patterns to change.
Regions that were only dry during the summer are now experiencing drought year-round; parts of the country where flooding was occasional but rare are now regularly experiencing massive, days-long storms that tear up houses and flood entire regions.
Flights are bumpier and being canceled with increasing frequency because of weather, as we’re just now sliding into this unknowable new era of severe weather weirding.
This is our new normal, and it’s costing us lives and billions of dollars every year, all to preserve the profits of a fossil fuel industry that knew in the 1960s that their product was poisoning the world and would lead to this outcome.
But don’t think that just because this is the new normal that this “normal” will last. The last time our planet saw CO2 levels at their current 422 parts-per-million, sea levels were 60 feet higher and trees were growing in Antarctica.
In other words, we’re on a path, not at a destination. The planet will catch up with all that CO2, and as it does our weather will continue to become more and more severe until we figure out a way to get CO2 levels back down to the 1950s count of just over 300 ppm.
Meanwhile, we’re pouring more CO2 into the atmosphere right now than at any time in human history, despite efforts among the world’s developed nations to reduce their carbon footprints.
The Russian invasion of Ukraine has been a major kick-in-the-pants to Europe to get off their dependence on fossil fuels and go green, as have high oil and gas prices around the world.
But here in America, Republicans on the Supreme Court (with 6 justices put on the bench with money from fossil-fuel billionaires) kneecapped the Biden administration’s ability to regulate CO2 and promote green energy.
In 2010, five Republicans on the Court legalized political bribery with their Citizens United decision. And, of course, Republicans deeply in the pocket of Big Oil, Gas, and Coal continue to deny climate change is even happening. Just last week, Congressman Scott Perry called climate change a massive “grift.”
And now the Heritage Foundation has, according to Raw Story, a plan for the next Republican administration to gut the EPA; end the Department of Energy’s (DOE) Office of Energy Efficiency and Renewable Energy and Office of Clean Energy Demonstrations; end “grid expansion for the benefit of renewable resources or supporting low/carbon generation”; ban EPA workers from using certain types of science; and prevent other states from copying California’s strict environmental standards for greenhouse gasses.
The fossil fuel industry has almost unlimited money to buy politicians, per Citizens United. The ten top recipients of fossil fuel money in Congress last year were:
Manchin, Joe (D-WV) $724,270
McCarthy, Kevin (R-CA) $396,284
Lankford, James (R-OK) $275,148
Pfluger, August (R-TX) $268,011
Kennedy, John (R-LA) $264,788
Murkowski, Lisa (R-AK) $249,808
Sinema, Kyrsten (D-AZ) $230,160
Fletcher, Lizzie (D-TX) $191,765
Cuellar, Henry (D-TX) $191,450

Scalise, Steve (R-LA) $181,263
Gonzales, Tony (R-TX) $174,461
Rubio, Marco (R-FL) $165,636
Amazing how little it costs to buy a member of Congress to keep your multi-billion-dollar-a-year profits flowing, isn’t it?
Here’s who opensecrets.orgsays are the top fossil fuel money recipients through their careers:
Romney, Mitt (R-UT) $8,291,262

Hutchison, Kay Bailey (R-TX) $2,332,021
Inhofe, James M (R-OK) $2,320,139
Pearce, Steve (R-NM) $2,236,714
Barton, Joe (R-TX) $2,211,987
Brady, Kevin (R-TX) $2,087,396
Scalise, Steve (R-LA) $1,847,013
Murkowski, Lisa (R-AK) $1,792,602
Americans are dying because these paid-off shills have either failed to act or actively blocked any meaningful change in our nation’s climate policy. They have blood on their hands, with more to come as every year brings more severe floods, storms, and drought.
We can no longer tolerate this morally criminal level of political malpractice, particularly since there is still time to act. And we must move quickly.
If America is to reclaim its position as a leader and role model for the world and stop the disastrous new climate “normal” we’re now entering from becoming radically more severe, we must get our use of fossil fuels under control.
That means ostracizing elected officials in the pocket of the industry, rolling back Citizens United so Big Oil and Big Coal can’t continue to bribe members of Congress, and throwing significant subsidies into greening our energy and transportation systems.
The climate emergency is here. We can’t wait any longer for major and dramatic worldwide action.
Editor’s Note: In this essay, Carl (one of our editors) describes the process of ocean acidification, and how it relates with other ecological crises.
First we need to know what an acid is. An acid is any substance (species) who’s molecules or ions are capable of donating a hydrogen ion proton (H+) to another substance in aqueous solution. The opposite of an acid is a base. Which is a substance who’s molecules or ions are able to accept a hydrogen ion from an acid. Acidic substances are usually identified by their sour taste while bases are bitter. The quantitative means to measure the degree to which a substance is acidic or basic is the detection of “potential of hydrogen” (pH) or “power of hydrogen”. This is expressed with a logarithmic scale 0 -14 that inversely indicates the activity of hydrogen ions in solution. The greater the amount of hydrogen ions which are measured below 7 the more acidic a substance is, going to 0. The less hydrogen ions are present which are measured above 7 the more basic a substance is, going to 14. So the pH values are inverse to number of hydrogen ions present. As the concentration of hydrogen ions increases the pH decreases (acidic). As the concentration of hydrogen ions decreases the pH increases (basic). With the value of 7 being neutral which is where pure distilled water falls on the scale. So acidification would be increasing hydrogen ions.
Basic (or alkaline) properties can be associated with the presence of hydroxide ions (OH−) in aqueous solution, and the neutralization of acids (H+) by bases can be explained in terms of the reaction of these two ions to give the neutral molecule water (H+ + OH− → H2O).
For millions of years the average pH of the ocean had maintained around 8.2, which is on the basic side of the scale. But since industrial development that number has dropped to slightly below 8.1. So not acidic but going in that direction. While this may not seem like a lot, remember the decrease is nonlinear and measures the amount of hydrogen ions present. A change in pH of 1 unit is equivalent to a tenfold change in the concentration of (H+) ions. So the drop of .11 units represents a 30% increase of (H+) ions than were present in the relative homeostasis state of preindustrial time. Ocean acidification is an increase in the dissolved hydrogen ions (H+) in the water.
What is causing this decrease in pH?
Oceans absorb carbon dioxide (CO2) from the atmosphere through wave action. Pre-industrialization there was a balance between the CO2 going into the water and coming out of the water. The pH was stable in this narrow range. Life in the oceans have evolved to survive in a balanced condition. Industrialization through the burning of fossil fuel has released increased amounts of CO2 into the atmosphere. This has caused the oceans to absorb more CO2. So here is where the chemistry comes into play. As CO2 dissolves in water (H2O) the two create Hydroxycarboxylic (Carbonic) Acid (H2CO3).
CO2 + H2O = H2CO3
This breaks down easily into Hydrogen Carbonate ions (HCO3) and H+ ions.
H2CO3 = HCO3 + H+
Hydrogen ions break off of the Carbonic Acid. So more CO2 means more H+ ions which means increased acidity.
And this is where the problem is. Shells are formed primarily of Calcium Carbonate (CaCO3). But Carbonate (CO3) binds more easily with H+ than with Calcium (Ca), CO3 + 2H+. This takes away Carbonate that would have bonded with the Calcium for shell production. Calcium is relatively constant, so it is the concentration of carbonate that determines formation of calcium carbonate. Less carbonate available makes it more difficult for corals, mollusks, echinoderms, calcareous algae and other shelled organisms to form Calcium Carbonate (CaCO3), their major mineral building block. Also, when Carbonate concentrations fall too low, already formed CaCO3 starts to dissolve. So, marine organisms have a harder time making new shells and maintaining the ones they’ve already got. This causes decreased calcification. In healthy humans, normal body pH average is 7.4. This is one of the main reasons why the pH in swimming pools should be maintained around 7.5.
The acid-base balance of the oceans has been critical in maintaining the Earth’s habitability and allowing the emergence of early life.
“Scientists have long known that tiny marine organisms—phytoplankton(microscopic aquatic plants)—are central to cooling the world by emitting an organic compound known as dimethylsulphide (DMS). Acidification affects phytoplankton in the laboratory by lowering the pH (i.e. acidifying) in plankton-filled water tanks and measuring DMS emissions. When they set the ocean acidification levels for what is expected by 2100 (under a moderate greenhouse gas scenario) they found that cooling DMS emissions fell.”
Given the importance of plankton, the fact that they are the life-support system for the planet and humanity cannot survive without them, the resulting effects will be disastrous. These organisms produce 50% of the world’s oxygen – every other breath animals take and are the basis for the food web. Covering more than 70 percent of the earth’s surface the oceans, the planets lungs, are in peril.
“Over the past 200 years, the oceans have absorbed approximately half of the carbon dioxide (CO2) emitted by human activities, providing long-term carbon storage. Without this sink, the greenhouse gas concentration in the atmosphere would be much higher, and the planet much warmer.”
But absorbing the CO2 causes changes in ocean chemistry, namely lowering pH and decreasing carbonate (CO3) concentrations.
On a human time scale these changes have been slow and steady relative to that baseline. But on a geological time scale this change is more rapid than any change documented over the last 300 million years. So organisms that have evolved tolerance to a certain range of conditions may encounter increasingly stressful or even lethal conditions in the coming decades.
We know this through carbon dating of ice cores which offer scientists’ the best source for historical climate data. Also deep-sea sediment cores from the ocean floor are used to detail the Earth’s history.
Estimates of future carbon dioxide levels, based on business-as-usual emission scenarios, indicate that by the end of this century the surface waters of the ocean could have a pH around 7.8 The last time the ocean pH was that low was during the middle Miocene, 14-17 million years ago. The Earth was several degrees warmer and a major extinction event was occurring. Animals take millions of years to evolve. They go extinct without an adequate timeframe to adapt to changes in habitat. Ocean acidification is currently affecting the entire ocean, including coastal estuaries and waterways. Billions of people worldwide rely on food from the ocean as their primary source of protein. Many jobs and economies in the U.S. and around the world depend on the fish and shellfish that live in the ocean.
By absorbing increased carbon dioxide from the atmosphere, the ocean reduces the warming impact of these emissions if they were to have remained in the atmosphere. Shockingly, though, only 1 percent of that heat has ended up in the atmosphere nearly 90 percent of it, is going into the ocean. There, it’s setting ocean heat records year after year and driving increasingly severe marine heat waves. As the ocean temperature has risen its ability to absorb CO2 has decreased. Colder ocean water dissolves more CO2, absorbing more from the atmosphere. But we have steadily increased carbon emissions. The percent of current emissions produced sequestered into the oceans is thirty.
It is unknown if this uptake can be sustained. What might happen to the Earth’s atmosphere if the ocean is unable to absorb continued increased carbon dioxide?
“If the seas are warmer than usual, you can expect higher air temperatures too, says Tim Lenton, professor of climate change at Exeter University. Most of the extra heat trapped by the build-up of greenhouse gases has gone into warming the surface ocean, he explains. That extra heat tends to get mixed downwards towards the deeper ocean, but movements in oceans currents – like El Niño – can bring it back to the surface.”
The ocean surface favors mineral formation, in deeper waters it dissolves.
We have enter a new Epoch, The Pyrocene
So it is obvious industrializing the oceans with offshore wind farms and deep sea mining, what capitalism calls the Blue Economy, will have the effect of continued acidification. But it will cause even more ramifications because it will have a direct impact on the species that live there and in the habitat where “raw” materials are extracted.
Regions of the ocean where the plankton communities are more efficiently utilizing organic matter, such as the deep sea, are places where the ocean has a naturally lower capacity to absorb some of the carbon dioxide produced by humans. “So understanding how zooplankton(small aquatic animals) communities process carbon, which, to them, represents food and energy, helps us to understand the role of the ocean in absorbing carbon dioxide in the atmosphere,” – Conner Shea doctoral student in the UH Mānoa School of Ocean and Earth Science and Technology (SOEST) Department of Oceanography.
We are headed for a Blue Ocean Event by 2030 – that is for the first time since ancient humans started roaming Earth several million years ago, an ice-free Arctic Ocean in the summer. The water instead of ice will be absorbing the suns heat rather than reflexing it back. Thus increasing sea temperature rise and disruption of the jet stream. This is basically what solar panels and wind turbines do. They make the earth hotter. Wind turbines extract the cooling breezes for their energy, the opposite of a fan. Miles and miles of solar panels destroy habitat and absorb the heat.
Continued industrialization will have the devastating effect of threats to food supplies, loss of coastal protection, diminished biodiversity and disruption of the carbon cycling – arising from these chemical reactions. This story involves a fundamental change within the largest living space on the planet, changes that are happening fast, and right now.
The oceans will find a new balance hundreds of thousands of years from now but between now and then marine organisms and environments will suffer.
What causes climate change?
The earth’s temperature cycles, glacial – interglacial, are primarily driven by periodic changes in the Earth’s orbit. Three distinct orbital cycles – called Milankovitch cycles. A Serbian scientist calculated that Ice Ages occur approximately every 41,000 years. Subsequent research confirms that they did occur at 41,000-year intervals between one and three million years ago. But about 800,000 years ago, the cycle of Ice Ages lengthened to 100,000 years, matching Earth’s deviation of orbit from circularity cycle. While various theories have been proposed to explain this transition, scientists do not yet have a clear answer. So CO2 historically has not caused climate change, it’s increased in the atmosphere during warmer temperatures and decreased during colder temperatures. Feedback loops have amplified changes initiated by orbital variations. But it is now humans that are currently increasing the amount of CO2 in the atmosphere by burning fossil fuels.
Strictly from an anthropocentric point of view, humanity could adapt to global warming and extreme weather changes. It will not survive the extinction of most marine plants and animals. The destruction of nature is more dangerous than climate change. It is sad that in the effort to save the climate and continuance of business as usual, we are destroying the environment. All of life came from the sea, it would be unwise to harm the birthplace of all species.
