A stark depiction of the threat hanging over the world’s mammals, reptiles, amphibians and other life forms has been published by the prestigious scientific journal, Nature. A special analysis carried out by the journal indicates that a staggering 41% of all amphibians on the planet now face extinction while 26% of mammal species and 13% of birds are similarly threatened.
Many species are already critically endangered and close to extinction, including the Sumatran elephant, Amur leopard and mountain gorilla. But also in danger of vanishing from the wild, it now appears, are animals that are currently rated as merely being endangered: bonobos, bluefin tuna and loggerhead turtles, for example.
In each case, the finger of blame points directly at human activities. The continuing spread of agriculture is destroying millions of hectares of wild habitats every year, leaving animals without homes, while the introduction of invasive species, often helped by humans, is also devastating native populations. At the same time, pollution and overfishing are destroying marine ecosystems.
“Habitat destruction, pollution or overfishing either kills off wild creatures and plants or leaves them badly weakened,” said Derek Tittensor, a marine ecologist at the World Conservation Monitoring Centre in Cambridge. “The trouble is that in coming decades, the additional threat of worsening climate change will become more and more pronounced and could then kill off these survivors.”
The problem, according to Nature, is exacerbated because of the huge gaps in scientists’ knowledge about the planet’s biodiversity. Estimates of the total number of species of animals, plants and fungi alive vary from 2 million to 50 million. In addition, estimates of current rates of species disappearances vary from 500 to 36,000 a year. “That is the real problem we face,” added Tittensor. “The scale of uncertainty is huge.”
In the end, however, the data indicate that the world is heading inexorably towards a mass extinction – which is defined as one involving a loss of 75% of species or more. This could arrive in less than a hundred years or could take a thousand, depending on extinction rates.
The Earth has gone through only five previous great extinctions, all caused by geological or astronomical events. (The Cretaceous-Jurassic extinction that wiped out the dinosaurs 65 million years ago was triggered by an asteroid striking Earth, for example.) The coming great extinction will be the work of Homo sapiens, however.
“In the case of land extinctions, it is the spread of agriculture that has been main driver,” added Tittensor. “By contrast it has been the over-exploitation of resources – overfishing – that has affected sealife.” On top of these impacts, rising global temperatures threaten to destroy habitats and kill off more creatures.
This change in climate has been triggered by increasing emissions – from factories and power plants – of carbon dioxide, a gas that is also being dissolved in the oceans. As a result, seas are becoming more and more acidic and hostile to sensitive habitats. A third of all coral reefs, which support more lifeforms than any other ecosystem on Earth, have already been lost in the last few decades and many marine experts believe all coral reefs could end up being wiped out before the end of the century.
Similarly, a quarter of all mammals, a fifth of all reptiles and a seventh of all birds are headed toward oblivion. And these losses are occurring all over the planet, from the South Pacific to the Arctic and from the deserts of Africa to mountaintops and valleys of the Himalayas.
A blizzard of extinctions is now sweeping Earth and has become a fact of modern life. Yet the idea that entire species can be wiped out is relatively new. When fossils of strange creatures – such as the mastodon – were first dug up, they were assumed to belong to creatures that still lived in other lands. Extant versions lived elsewhere, it was argued. “Such is the economy of nature,” claimed Thomas Jefferson, who backed expeditions to find mastodons in the unexplored interior of America.
Then the French anatomist Georges Cuvier showed that the elephant-like remains of the mastodon were actually those of an “espèce perdue” or lost species. “On the basis of a few scattered bones, Cuvier conceived of a whole new way of looking at life,” notes Elizabeth Kolbert in her book, The Sixth Extinction: An Unnatural History. “Species died out. This was not an isolated but a widespread phenomenon.”
Since then the problem has worsened with every decade, as the Nature analysis makes clear. Humans began by wiping out mastodons and mammoths in prehistoric times. Then they moved on to the eradication of great auks, passenger pigeons – once the most abundant bird in North America – and the dodo in historical time. And finally, in recent times, we have been responsible for the disappearance of the golden toad, the thylacine – or Tasmanian tiger – and the Baiji river dolphin. Thousands more species are now under threat.
In an editorial, Nature argues that it is now imperative that governments and groups such as the International Union for Conservation of Nature begin an urgent and accurate census of numbers of species on the planet and their rates of extinction. It is not the most exciting science, the journal admits, but it is vitally important if we want to start protecting life on Earth from the worst impacts of our actions. The loss for the planet is incalculable – as it is for our own species which could soon find itself living in a world denuded of all variety in nature. As ecologist Paul Ehrlich has put it: “In pushing other species to extinction, humanity is busy sawing off the limb on which it perches.”
22 years ago on this very continent was brought to the negotiating table the crisis of climate change. Many evasive proposals, claims to turn the crisis into an opportunity for business, denials, omissions and grand tragedies embody the climate crisis in the territories. A balance of 22 years of indifference and cynicism.
Governments and transnational interests continue to invest in the destruction of forests, rivers, oceans, jungles, mashlands, mountains and deserts; living spaces that end up being sacrificed in the name of “development” and “progress”.
In these 22 years, we are far from believing that the solution will come from governments; that the market will contribute to environmental conservation, or that the commodification of nature will protect the climate.
Our view is the way of indigenous communities that have known to preserved ecosystems, in farming communities who struggle to protect their lands, in women who work caringly in the rivers, in the children that keep alive their capacity of fascination with nature, and in the inhabitants of large cities who know that they have been robbed from nature since birth. Our guardians.
Us, the very ones who we are, have come here to convince you (and convince ourselves of the certainty that the world we want already exists), as there are colors of the earth, the suns that shine us, and the ways of our guardians that defend the territories around the globe.
This is why we call to find ourselves on the road to the COP20, to join our histories, our views, and our ways that demand climate justice under these guiding principles:
1. Maintain the fossil fuels underground is not only a priority to halting environmental devastation, but to end one of the evils that has so hurt and changed the pace of the climate in very few decades.
2. Ban the financialization of forests and the commodification of the functions of nature, as they are not a solutions to reduce emissions of carbon gases into the atmosphere; strategies which represent false solutions that have increased the destruction of ecosystems, the breakdown of communitarian social fabric and organization.
3. Water, as a common good can no longer be conceived as a commodity. Dams and hydroelectric dams are part of the mining and energy industries. The production of hydroelectric power is what keeps widening the gap of environmental devastation.
The aggressiveness with which the occupation of territories intends to expand itself does not depend on the political color of governments, but rather is linked to the perpetuation of the capitalist system under the same logic of accumulation at the expense of nature and communities.
Therefore, it becomes more urgent to find one another, Us.
They are the ones who will find the solutions- It’s us, the unadaptaded, the unadaptable climate change- It is us that can and must contain the war against nature.
The body of an indigenous leader who was opposed to a major mining project in Ecuador has been found bound and buried, days before he planned to take his campaign to climate talks in Lima.
The killing highlights the violence and harassment facing environmental activists in Ecuador, following the confiscation earlier this week of a bus carrying climate campaigners who planned to denounce president Rafael Correa at the United Nations conference.
The victim, José Isidro Tendetza Antún, a former vice-president of the Shuar Federation of Zamora, had been missing since 28 November, when he was last seen on his way to a meeting of protesters against the Mirador copper and gold mine. After a tip-off on Tuesday, his son Jorge unearthed the body from a grave marked “no name”. The arms and legs were trussed by a blue rope.
Other members of the community said Tendetza had been offered bribes and had his crops burned in an attempt to remove him from the area.
Domingo Ankuash, a Shuar leader, said there were signs Tendetza had been tortured, but the full facts had yet to come to light. He said the family were extremely unhappy with the investigation and what they said was the reluctance of the authorities to conduct a timely autopsy.
“His body was beaten, bones were broken,” said Ankuash. “He had been tortured and he was thrown in the river. The mere fact that they buried him before telling us, the family, is suspicious.”
Tendetza had been a prominent critic of Mirador, an open-cast pit that has been approved in an area of important biodiversity that is also home to the Shuar, Ecuador’s second-biggest indigenous group.
The project is operated by Ecuacorriente – originally a Canadian-owned firm that was brought by a Chinese conglomerate, CCRC-Tongguan Investment, in 2010. According to the Confederation of Indigenous Nationalities of Ecuador, the project will devastate around 450,000 acres of forest.
“This is a camouflaged crime,” said Ankuash. “In Ecuador, multinational companies are invited by the government and get full state security from the police and the army. The army and police don’t provide protection for the people, they don’t defend the Shuar people. They’ve been bought by the company.
“The authorities are complicit in this crime,” Ankuash claimed. “They will never tell us the truth.” He added: “[Tendetza] was not just anyone. He was a powerful leader against the company. That’s why they knocked down his house and burnt his farm.
“The government will never give us a response, justice belongs to them. They will call us terrorists but that doesn’t mean we are not going to shut up.”
Several other Shuar opponents of Mirador have died as a result of the conflict in recent years, including Bosco Wisum in 2009 and Freddy Taish in 2013, according to Amazon Watch.
An initial autopsy said the circumstances of Tendetza’s death were unclear. Harold Burbano, of the human rights organisation INREDH, said there was a suspicion that the killing was related to his work as a land defender.
“There has been a rise of conflicts since the transnational mining company entered the area, significantly increasing the risks faced by community leaders,” he said.
Tendetza had planned to condemn the project at a Rights of Nature Tribunal organised by NGOs at the climate talks which are taking place this week in the Peruvian capital.
Luis Corral, an advisor to Ecuador’s Assembly of the People of the South, an umbrella group for indigenous federations in southern Ecuador, said that if Tendetza had been able to travel to the COP20 it would have put in “grave doubt the honorability and the image of the Ecuadorean government as a guarantor of the rights of nature”.
“We believe that this murder is part of a pattern of escalating violence against indigenous leaders which responds to the Ecuadorean government and the companies’ need to clear the opposition to a mega-mining project in the Cordillera del Condor,” he said.
“The state through the police and the judiciary is involved in hiding this violent crime because of the elemental irregularities in the proceedings. The body was buried without informing the family. They weren’t allowed to see the second autopsy.”
Tendetza’s killing highlights the risks facing environmental activists in Ecuador. Earlier this week, a group of campaigners travelling in a “climate caravan” were stopped six times by police on their way to Lima and eventually had their bus confiscated.
The activists said they were held back because president Correa wants to avoid potentially embarrassing protests at the climate conference over his plan to drill for oil in Yasuni, an Amazon reserve and one of the most biodiverse places on earth.
Once lauded for being the first nation to draw up a “green constitution”, enshrining the rights of nature, Ecuador’s environmental reputation has nosedived in recent years as Correa has put more emphasis on exploitation of oil, gas and minerals, partly to pay off debts owed to China.
Saddle Road at the entrance to the Mauna Kea Observatory Road
Native Hawaiians and non-Hawaiians will gather for a peaceful protest against the Astronomy industry and the “State of Hawaii’s” ground- breaking ceremony for a thirty-meter telescope (TMT) on the summit of Mauna Kea.
Native Hawaiians and non-Hawaiians will gather for a peaceful protest
against the Astronomy industry and the “State of Hawaii’s” ground-
breaking ceremony for a thirty-meter telescope (TMT) on the summit of
Mauna Kea.
CULTURAL ISSUES: Mauna Kea is sacred to the Hawaiian people, who
maintain a deep connection and spiritual tradition there that goes
back millennia.
“The TMT is an atrocity the size of Aloha Stadium,” said Kamahana
Kealoha, a Hawaiian cultural practitioner. “It’s 19 stories tall,
which is like building a sky-scraper on top of the mountain, a place
that is being violated in many ways culturally, environmentally and
spiritually.” Speaking as an organizer of those gathering to protest,
Kealoha said, “We are in solidarity with individuals fighting against
this project in U.S. courts, and those taking our struggle for
de-occupation to the international courts. Others of us must protest
this ground-breaking ceremony and intervene in hopes of stopping a
desecration.”
Clarence “Ku” Ching, longtime activist, cultural practitioner, and a
member of the Mauna Kea Hui, a group of Hawaiians bringing legal
challenges to the TMT project in state court, said, “We will be
gathering at Pu’u Huluhulu, at the bottom of the Mauna Kea Access
Road, and we will be doing prayers and ceremony for the mountain.”
When asked if he will participate in protests, he said, “We’re on the
same side as those who will protest, but my commitment to Mauna Kea is
in this way. We are a diverse people…everyone has to do what they know
is pono.”
ENVIRONMENTAL ISSUES: The principle fresh water aquifer for Hawaii
Island is on Mauna Kea, yet there have been mercury spills on the
summit; toxins such as Ethylene Glycol and Diesel are used there;
chemicals used to clean telescope mirrors drain into the septic
system, along with half a million gallons a year of human sewage that
goes into septic tanks, cesspools and leach fields.
“All of this poisonous activity at the source of our fresh water
aquifer is unconscionable, and it threatens the life of the island,”
said Kealoha. “But that’s only part of the story of this mountain’s
environmental fragility. It’s also home to endangered species, such as
the palila bird, which is endangered in part because of the damage to
its critical habitat, which includes the mamane tree.”
LEGAL ISSUES: Mauna Kea is designated as part of the Crown and
Government lands of the Hawaiian Kingdom.
Professor Williamson PC Chang, from the University of Hawaii’s
Richardson School of Law, said, “The United States bases its claim to
the Crown and Government land of the Hawaiian Kingdom on the 1898
Joint Resolution of Congress, but that resolution has no power to
convey the lands of Hawaii to the U.S. It’s as if I wrote a deed
saying you give your house to me and I accepted it. Nobody gave the
land to the U.S., they just seized it.”
“Show us the title,” said Kealoha. “If the so-called ‘Treaty of
Annexation’ exists, that would be proof that Hawaiian Kingdom citizens
gave up sovereignty and agreed to be part of the United States 121
years ago. But we know that no such document exists. The so-called
‘state’ does not have jurisdiction over Mauna Kea or any other land in
Hawaii that it illegally leases out to multi-national interests.”
“I agree with how George Helm felt about Kahoolawe,” said Kealoha. “He
wrote in his journal: ‘My veins are carrying the blood of a people who
understood the sacredness of land and water. Their culture is my
culture. No matter how remote the past is it does not make my culture
extinct. Now I cannot continue to see the arrogance of the white man
who maintains his science and rationality at the expense of my
cultural instincts. They will not prostitute my soul.’”
“We are calling on everyone, Hawaiians and non-Hawaiians alike, to
stand with us, to protect Mauna Kea the way George and others
protected Kahoolawe. I ask myself every day, what would George Helm
do? Because we need to find the courage he had and stop the
destruction of Mauna Kea.”
Carbon dioxide is being accumulated in the atmosphere at the fastest rate since records began, as scientists warn that the oceans and forests may have absorbed so much CO2 that their crucial function as “carbon sinks” is now severely threatened.
The jump in atmospheric CO2 is partly the result of rising carbon emissions as the world burns ever-more fossil fuels, according to the latest World Meteorological Organisation report, which finds the concentration of carbon increased by nearly three parts per million (ppm) to 396ppm last year.
But, crucially, preliminary data in the report indicates that the jump could also be attributed to “reduced CO2 uptake by the Earth’s biosphere” – the first time the effectiveness of the world’s great carbon sinks has been scientifically called into question.
Scientists said they were puzzled and extremely concerned by prospect of reduced absorption of the world’s oceans and plants, which they cannot explain and which threatens to accelerate the build-up of heat-trapping greenhouse gases in the atmosphere if the trend continues.
“That carbon dioxide concentrations continued to surge upwards last year is worrying news,” said Professor Dave Reay, of the University of Edinburgh.
“Of particular concern is the indication that carbon storage in the world’s forests and oceans may be faltering. So far these ‘carbon sinks’ have been locking away almost half of all the carbon dioxide we emit,” Professor Reay added.
“If they begin to fail in the face of further warming then our chances of avoiding dangerous climate change become very slim indeed.”
The plants and the oceans each typically absorb about a quarter of humanity’s CO2 emissions every year, with the other half going into the atmosphere, where it can remain for hundreds of years.
The last time there was a reduction in the biosphere’s ability to absorb carbon was in 1998, a year in which extensive forest fires and dry weather killed off lots of plants, dealing a blow to the world’s carbon sink.
But Dr Oksana Tarasova, chief of the atmospheric research division at the WMO, said this time it is much more worrying because there have been no obvious impacts on the biosphere this year.
“This problem is very serious. It could be that the biosphere is already at its limit, or it may be close to reaching it. Or it may be that it just becomes less effective at absorbing carbon. But it’s still very concerning,” said Dr Tarasova.
The worst-case scenario in which the carbon sink ceased to function at all would double the rate at which CO2 emissions accumulate in the atmosphere, significantly increasing the fallout of climate change, such as storms, droughts and temperature increases, Dr Tarasova said.
The latest WMO survey packed a second environmental punch – revealing that the oceans are currently acidifying at a rate that is unprecedented in the past 300 million years.
This is because they are absorbing about 4kg of carbon dioxide for every person on the planet, the report says.
The WMO’s findings intensified calls for co-ordinated global action to limit global warming to 2C, beyond which its consequences become increasingly devastating.
“We are running out of time. Past, present and future CO2 emissions will have a cumulative impact on both global warming and ocean acidification. The law of physics are non-negotiable,” said the WMO’s secretary-general Michel Jarraud. He added that, rather than rising, fossil fuel and other emissions badly need to come down.
This film, by DGR member Max Wilbert, brings you the voices of climate scientists – in their own words.
Rising temperatures in the Arctic are contributing the melting sea ice, thawing permafrost, and destabilization of a system that has been called “Earth’s Air Conditioner”. Global warming is here and is impacting weather patterns, natural systems, and human life around the world – and the Arctic is central to these impacts.

At 16:15, the footage of methane venting from the seafloor was captured by Ocean Networks Canada / CSSF. It is venting from a place called “Bubbly Gulch” near one of their seafloor observatory nodes called Clayoquot Slope (a.k.a. ODP 889), located off the coast of Vancouver Island, not Oregon. The footage was captured in May 2010 at a depth of 1257 m. https://www.youtube.com/watch?v=sEHFit_5l-Y
