The climate crisis of the 21st century has been caused largely by just 90 companies, which between them produced nearly two-thirds of the greenhouse gas emissions generated since the dawning of the industrial age, new research suggests.
The companies range from investor-owned firms – household names such as Chevron, Exxon and BP – to state-owned and government-run firms.
The analysis, which was welcomed by the former vice-president Al Gore as a “crucial step forward” found that the vast majority of the firms were in the business of producing oil, gas or coal, found the analysis, which has been published in the journal Climatic Change.
“There are thousands of oil, gas and coal producers in the world,” climate researcher and author Richard Heede at the Climate Accountability Institute in Colorado said. “But the decision makers, the CEOs, or the ministers of coal and oil if you narrow it down to just one person, they could all fit on a Greyhound bus or two.”
Half of the estimated emissions were produced just in the past 25 years – well past the date when governments and corporations became aware that rising greenhouse gas emissions from the burning of coal and oil were causing dangerous climate change.
Many of the same companies are also sitting on substantial reserves of fossil fuel which – if they are burned – puts the world at even greater risk of dangerous climate change.
Climate change experts said the data set was the most ambitious effort so far to hold individual carbon producers, rather than governments, to account.
The United Nations climate change panel, the IPCC, warned in September that at current rates the world stood within 30 years of exhausting its “carbon budget” – the amount of carbon dioxide it could emit without going into the danger zone above 2C warming. The former US vice-president and environmental champion, Al Gore, said the new carbon accounting could re-set the debate about allocating blame for the climate crisis.
Leaders meeting in Warsaw for the UN climate talks this week clashed repeatedly over which countries bore the burden for solving the climate crisis – historic emitters such as America or Europe or the rising economies of India and China.
Gore in his comments said the analysis underlined that it should not fall to governments alone to act on climate change.
“This study is a crucial step forward in our understanding of the evolution of the climate crisis. The public and private sectors alike must do what is necessary to stop global warming,” Gore told the Guardian. “Those who are historically responsible for polluting our atmosphere have a clear obligation to be part of the solution.”
Between them, the 90 companies on the list of top emitters produced 63% of the cumulative global emissions of industrial carbon dioxide and methane between 1751 to 2010, amounting to about 914 gigatonne CO2 emissions, according to the research. All but seven of the 90 were energy companies producing oil, gas and coal. The remaining seven were cement manufacturers.
The list of 90 companies included 50 investor-owned firms – mainly oil companies with widely recognised names such as Chevron, Exxon, BP , and Royal Dutch Shell and coal producers such as British Coal Corp, Peabody Energy and BHP Billiton.
Some 31 of the companies that made the list were state-owned companies such as Saudi Arabia’s Saudi Aramco, Russia’s Gazprom and Norway’s Statoil.
Nine were government run industries, producing mainly coal in countries such as China, the former Soviet Union, North Korea and Poland, the host of this week’s talks.
Experts familiar with Heede’s research and the politics of climate change said they hoped the analysis could help break the deadlock in international climate talks.
“It seemed like maybe this could break the logjam,” said Naomi Oreskes, professor of the history of science at Harvard. “There are all kinds of countries that have produced a tremendous amount of historical emissions that we do not normally talk about. We do not normally talk about Mexico or Poland or Venezuela. So then it’s not just rich v poor, it is also producers v consumers, and resource rich v resource poor.”
Michael Mann, the climate scientist, said he hoped the list would bring greater scrutiny to oil and coal companies’ deployment of their remaining reserves. “What I think could be a game changer here is the potential for clearly fingerprinting the sources of those future emissions,” he said. “It increases the accountability for fossil fuel burning. You can’t burn fossil fuels without the rest of the world knowing about it.”
Others were less optimistic that a more comprehensive accounting of the sources of greenhouse gas emissions would make it easier to achieve the emissions reductions needed to avoid catastrophic climate change.
John Ashton, who served as UK’s chief climate change negotiator for six years, suggested that the findings reaffirmed the central role of fossil fuel producing entities in the economy.
“The challenge we face is to move in the space of not much more than a generation from a carbon-intensive energy system to a carbonneutral energy system. If we don’t do that we stand no chance of keeping climate change within the 2C threshold,” Ashton said.
“By highlighting the way in which a relatively small number of large companies are at the heart of the current carbon-intensive growth model, this report highlights that fundamental challenge.”
Meanwhile, Oreskes, who has written extensively about corporate-funded climate denial, noted that several of the top companies on the list had funded the climate denial movement.
“For me one of the most interesting things to think about was the overlap of large scale producers and the funding of disinformation campaigns, and how that has delayed action,” she said.
The data represents eight years of exhaustive research into carbon emissions over time, as well as the ownership history of the major emitters.
The companies’ operations spanned the globe, with company headquarters in 43 different countries. “These entities extract resources from every oil, natural gas and coal province in the world, and process the fuels into marketable products that are sold to consumers on every nation on Earth,” Heede writes in the paper.
The largest of the investor-owned companies were responsible for an outsized share of emissions. Nearly 30% of emissions were produced just by the top 20 companies, the research found.
By Heede’s calculation, government-run oil and coal companies in the former Soviet Union produced more greenhouse gas emissions than any other entity – just under 8.9% of the total produced over time. China came a close second with its government-run entities accounting for 8.6% of total global emissions.
ChevronTexaco was the leading emitter among investor-owned companies, causing 3.5% of greenhouse gas emissions to date, with Exxon not far behind at 3.2%. In third place, BP caused 2.5% of global emissions to date.
The historic emissions record was constructed using public records and data from the US department of energy’s Carbon Dioxide Information and Analysis Centre, and took account of emissions all along the supply chain.
The centre put global industrial emissions since 1751 at 1,450 gigatonnes.

A new report on minorities and indigenous people warns that the global ‘intensification’ in the exploitation of natural resources is leading to mounting conflicts for the world’s 370 million indigenous people.
The report for 2012 by the London-based human rights group, Minority Rights Group International (MRG), says indigenous peoples “in every region of the world” face the risk of being “driven from their land and natural resources.”
The land and resources are all “vital for their livelihoods, their culture and often their identity as a people,” Vital Bambanze, chair of the UN Expert Mechanism on the Rights of Indigenous Peoples, said in the report.
From the Batwa of the Great Lakes region in Central Africa, and the Endorois and Ogiek in Kenya, to hill tribes in northern Thailand, Bedouin in the Middle East and Uighurs in China’s Xinjiang province – all “struggle to maintain their cultural integrity against their respective governments’ desire to put national development first,” Bambanze said.
Unprecedented demand for resources in Asia
The report says the unprecedented demand for natural resources across Asia is “feeding ethnic conflict and displacement and is a severe threat to the lands, livelihoods and the way of life of minorities and indigenous people.”
Carl Soderbergh, an MRG spokesperson, warns the situation faced by indigenous groups is deteriorating world-wide.
“In terms of the trends globally what has been happening over the last decade is that there’s been an intensification of the exploitation of natural resources pushing into areas populated by minorities and indigenous peoples,” Soderbergh told DW.
In regions such as Latin America, the issues faced by communities centered on mining and logging, in North America on tar-sands mining, there were conflicts over wind farms and iron ore mining in the Arctic, while in Africa, indigenous communities faced the leasing of thousands of hectares of land for corporations or foreign governments.
“All governments are chasing a dominant development paradigm in which today minorities and indigenous peoples don’t really have a place and that is a problem,” he said.
In China, investment in mining has forced herders off traditional grazing lands and ancestral villages in regions such as Xinjiang Uighur Autonomous Region, as well as in Tibet.
In Vietnam, over 90,000 people, mostly ethnic Thai, were relocated to make way for the Son La hydropower plant with Vietnamese scientists saying many were left without access to agricultural land.
Meanwhile, in Cambodia’s Prey Lang Forest region, home to the Kuy indigenous people, official land grants of tens of thousands of hectares of forest for mineral extraction, timber and rubber plantations have forced many people to give up their traditional livelihoods.
Conflict has also been evident in Indonesia in areas of increased palm oil plantation development and the mining industry in Papua.
Investment from China seen as a driver for economic growth
Nicole Girard, the rights group’s Asia Program Director, says levels of conflict over land is increasing in South East Asia, driven by foreign investment, including from China.
“It’s definitely increasing, the resource exploitation in indigenous people’s territories; in Southeast Asia, the economies of Laos and Vietnam are opening to more foreign investment, including lots of Chinese investment and including Burma,” Girard said.
Girard says the increased fighting in Myanmar’s ethnic controlled Kachin State over the past year is directly linked to conflict over resource investment largely by Chinese businesses.
Myanmar, led by the military-backed civilian government of President Thein Sein, has been undergoing reforms over the past year to improve its human rights situation. But Naw San, General Secretary of the Students and Youth Congress Burma (Myanmar) says despite steps to peace talks with ethnic groups in Myanmar, the development process is still not inclusive.
“We are still worried that, like in the past, investment and development projects will be dealt with by the central government and that there will be (no real) engagement or consultations with the process on the ground,” Naw San told DW.
“What the ethnic (communities) need now is national equality,” he said.
Two thirds of Indigenous People live in Asia
The Asia Indigenous People’s Pact (AIPP) Foundation, in a separate report, noted that two thirds of the world’s 370 million self-identified indigenous peoples live in Asia.
And those people, according to the AIPP Foundation, “are currently marginalized and subordinated economically, politically and culturally.”
They are “overrepresented among the poor, illiterate, malnourished and stunted,” it said.
AIPP’s report says for many in the region “militarization, (the) plundering of resources, forced relocation, cultural genocide and discrimination in everyday life are common experiences.”
The report pointed to the construction of dams in Asia, which since the 1960s, has led to “massive displacements, loss of livelihoods, and food insecurity of indigenous peoples in India, the Philippines, Laos and Malaysia.”
Bernice See, an AIPP coordinator, said governments give priority to economic ventures and investments over people’s rights.
See called on Asia’s governments to respect the UN’s Declaration of the Rights of Indigenous peoples and the provisions calling for the “free prior of informed consent from any development that comes into their territory.”
“These governments should have the moral obligation to respect these agreements. The declaration should be used as a framework for dealing with indigenous people,” she said.

Workers have begun the delicate task of removing spent fuel rods from a damaged reactor at the Fukushima Daiichi nuclear power plant, more than two-and-a-half years after the facility suffered a triple meltdown.
The operation to remove more than 1,331 used fuel assemblies, and 202 unused assemblies, began on Monday and is expected to take just over a year. Decommissioning the entire site is expected to take at least 30 years.
The plant’s operator, Tokyo Electric Power [Tepco], said the fuel removal was an important step in decommissioning the plant, which experienced multiple meltdowns and explosions after Japan’s north-east coast was hit by a powerful earthquake and tsunami in March 2011.
Tepco brushed off fears that removing the spent fuel rods from a storage pool near the roof of reactor No4 could cause a serious accident. Some experts have warned that a collision involving the fuel assemblies, a sudden loss of coolant water or another big earthquake could cause a chain reaction and the release of huge quantities of radiation into the atmosphere.
Reactor No4 was closed for routine maintenance at the time of the disaster and so did not suffer a meltdown. But a hydrogen explosion on 15 March 2011 blew the walls and roof off the reactor building, leaving it vulnerable to further damage from earthquakes.
The utility has since reinforced the building with a huge steel canopy and insists the structure can withstand seismic events of the same intensity that shook the plant in March 2011.
But it conceded that the fuel assemblies needed to be moved to a safer storage site as soon as possible.
“After the explosion, one big challenge was to deal with the spent fuel pool because if the water evaporated it would cause a radioactive cloud stretching all the way to Tokyo, which would have to be evacuated,” Yuichi Okamura, deputy manager of the water treatment department at Fukushima Daiichi, told the Guardian on Monday.
“It was a big challenge, so today is a big success for the cleanup teams.”
Yoshimi Hitosugi, a Tepco spokesman, said: “This is an important moment. It is one big step towards decommissioning the reactor.” He added that three fuel assemblies had been discovered that were damaged prior to the tsunami and measures were being taken to deal with them.
Hitosugi said the firm was confident that the workers would be able to cope with any debris caused by the explosion that remained in the spent fuel pool, adding that it would not compromise the fuel removal operation.
Tepco’s president, Naomi Hirose, said the fuel extraction “represents the beginning of a new and important chapter in our work”, and thanked plant workers for the “ingenuity, diligence, and courage that made this achievement possible”.
The utility believes that a specially chosen team of 36 men will need until late 2014 to remove all of the fuel assemblies from the pool, located 130 feet above ground, and place them in submerged protective casks. The casks will then be taken to ground level and transported to a more stable storage pool nearby.
Each cask can hold up 22 assemblies comprising between 60 and 80 fuel rods. Workers will remove the fresh fuel assemblies first because they are easier to handle.
“The extraction work started at 3:18pm and the first fuel completed its extraction from the fuel rack to the cask placed inside the pool at 3:57pm as planned, following thorough safety preparations with the co-operation of many partner companies and individual workers,” Tepco said in a statement.
But anti-nuclear campaigners have voiced concern over Tepco’s ability to complete the work without incident following revelations that up to 300 tonnes of radioactive water are leaking from the site into the sea every day.
The utility also came under fire this summer for installing poorly designed tanks that leaked toxic water.
“We are concerned that Tepco may not be capable of conducting this risky operation safely, and that there are significant risks involved in this operation,” said Kazue Suzuki, a nuclear campaigner with Greenpeace Japan.
“Tepco’s inability to solve the problems with leaking tanks that store contaminated water, and the continued flow of contaminated water from the site to the ocean adds to our concerns about its ability to handle this dangerous operation to remove spent fuel.
“If Tepco makes mistakes again and can’t handle this task, workers could be exposed to excessive levels of radiation and in a worst-case scenario there could be a massive new release of radiation to the atmosphere.”

In a major setback for Chevron, the Ecuadorian National Court issued its long-awaited decision in favor of a $9 billion pollution judgment against Chevron upholding and affirming lower court rulings. The court’s decision is final.
In its 222-page opinion, the supreme court affirmed earlier decisions by a Lago Agrio court and the appellate court for $9 billion but rejected the additional $9 billion in punitive damages previously imposed for not apologizing, given that provision is not explicitly permitted in Ecuadorian law. The supreme court also lamented the plaintiffs waiting 20 years for justice and attributed this largely to delaying tactics by Chevron. This ruling constitutes a landmark case for corporate responsibility.
“This is an extraordinary, unprecedented triumph for indigenous and local communities over one of the world’s worst polluters,” said Donald Moncayo, a representative from the Amazon Defense Coalition for 30,000 Ecuadorian rainforest villagers and plaintiffs, who was in New York to testify in a retaliatory lawsuit filed by Chevron against lawyers for the plaintiffs in the Ecuador case.
Meanwhile, at the trial in New York, Judge Kaplan repeatedly assisted Chevron in intimidating and attacking key Ecuadorian witnesses and the defendant’s legal team.
In the retaliatory RICO lawsuit, Moncayo was subjected to a lengthy cross-examination by Chevron, after which Judge Kaplan ordered him to turn over a copy of his hard drive to the court.
Christopher Gowen, a legal ethics professor at American University Washington College of Law, was present in court and commented, “Watching an American judge threaten a foreigner in an American court with criminal penalties without the advice of counsel on a highly questionable court order defies everything our justice system stands for.”
“Ecuador’s supreme court has given careful consideration to each of Chevron’s conspiratorial claims, and has rejected them one-by-one,” said Han Shan, spokesperson for legal team representing the Ecuadorian Villagers. “While the company’s complaints have found a sympathetic ear in Judge Kaplan’s courtroom, the fact remains that Chevron has been found liable by the court it fought to have the case heard by, and that decision has now been upheld at the highest level.”
“We witnessed outrageous abuse of power by the very pro-Chevron Judge Kaplan and there was nearly no mainstream media and no cameras to capture it,” said Atossa Soltani of Amazon Watch. “This can only have a chilling effect on the willingness of witnesses in human rights cases to come forth to provide facts and pertinent information in an impartial setting where they are not going to feel threatened.”
The Ecuadorians and their supporters have called for an end to Chevron’s retaliatory lawsuit and the ongoing “rigged show trial” before Judge Kaplan, who has displayed outright hostility to the Ecuadorians’ legal efforts to demand a cleanup. Judge Kaplan has also made repeated disparaging on the record comments about Ecuador’s judicial system.
Chevron has no assets in Ecuador, forcing the communities to pursue the oil giant’s assets around the world through enforcement actions currently underway in Brazil, Argentina and Canada.
Texaco operated in Ecuador until 1992, and Chevron absorbed the company in 2001, assuming all of its predecessor’s assets and liabilities. Chevron has admitted to dumping nearly 18 billion gallons of toxic wastewater into rivers and streams relied upon by thousands of people for drinking, bathing, and fishing. The company also abandoned hundreds of unlined, open waste pits filled with crude, sludge, and oil drilling chemicals throughout the inhabited rainforest region. Multiple independent health studies have shown an epidemic of oil-related birth defects, cancers, and other illness.

By Max Wilbert / Deep Green Resistance Great Basin
In June 1988, climatologist and NASA scientist James Hansen stood before the Energy and Natural Resources Committee in the United States Senate. The temperature was a sweltering 98 degrees.
“The earth is warmer in 1988 than at any time in the history of instrumental measurements,” Hansen said. “The global warming now is large enough that we can ascribe with a high degree of confidence a cause-and-effect relationship to the greenhouse effect… Our computer climate simulations indicate that the greenhouse effect is already large enough to begin to effect the probability of extreme events such as summer heat waves.”
Hansen has authored some of the most influential scientific literature around climate change, and like the vast majority of climate scientists, has focused his work on the last 150 to 200 years – the period since the industrial revolution.
This period has been characterized by the widespread release of greenhouse gases like carbon dioxide (CO2) and methane (CH4), and by the clearing of land on a massive scale – the plowing of grasslands and felling of forests for cities and agricultural crops.
Now, the world is on the brink of catastrophic climate change. Hansen and other scientists warn us that if civilization continues to burn fossil fuels and clear landscapes, natural cycles may be disrupted to the point of complete ecosystem breakdown – a condition in which the planet is too hot to support life. Hansen calls this the Venus Syndrome, named after the boiling planet enshrouded in clouds of greenhouse gases.
“If we also burn the tar sands and tar shale [low grade, high carbon fossil fuels], I believe the Venus syndrome is a dead certainty,” Hansen has said.
If humanity wishes to have a chance of avoiding this fate, it is important that we understand global warming in detail. Why is it happening? When did it start? What fuels it? And, most importantly, what can stop it?
How old is global warming?
New studies are showing that the current episode of global warming may be a great deal older than previously believed – which may entirely change our strategy to stop it.
While fossil fuels have only been burned on a large scale for 200 years, land clearance has been a defining characteristic of civilizations – cultures based around cities and agriculture – since they first emerged around 8,000 years ago.
This land clearance has impacts on global climate. When a forest ecosystem is converted to agriculture, more than two thirds of the carbon that was stored in that forest is lost, and additional carbon stored in soils rich in organic materials will continue to be lost to the atmosphere as erosion accelerates.
Modern science may give us an idea of the magnitude of the climate impact of this pre-industrial land clearance. Over the past several decades of climate research, there has been an increasing focus on the impact of land clearance on modern global warming. The Intergovernmental Panel on Climate Change, in it’s 2004 report, attributed 17% of global emissions to cutting forests and destroying grasslands – a number which does not include the loss of future carbon storage or emissions directly related to this land clearance, such as methane released from rice paddies or fossil fuels burnt for heavy equipment.
Some studies show that 50% of the global warming in the United States can be attributed to land clearance – a number that reflects the inordinate impact that changes in land use can have on temperatures, primarily by reducing shade cover and evapotranspiration (the process whereby a good-sized tree puts out thousands of gallons of water into the atmosphere on a hot summer day – their equivalent to our sweating).
So if intensive land clearance has been going on for thousands of years, has it contributed to global warming? Is there a record of the impacts of civilization in the global climate itself?
10,000 years of Climate Change
According to author Lierre Keith, the answer is a resounding yes. Around 10,000 years ago, humans began to cultivate crops. This is the period referred to as the beginning of civilization, and, according to the Keith and other scholars such as David Montgomery, a soil scientist at the University of Washington, it marked the beginning of land clearance and soil erosion on a scale never before seen – and led to massive carbon emissions.
“In Lebanon (and then Greece, and then Italy) the story of civilization is laid bare as the rocky hills,” Keith writes. “Agriculture, hierarchy, deforestation, topsoil loss, militarism, and imperialism became an intensifying feedback loop that ended with the collapse of a bioregion [the Mediterranean basin] that will most likely not recover until after the next ice age.”
Montgomery writes, in his excellent book Dirt: The Erosion of Civilizations, that the agriculture that followed logging and land clearance led to those rocky hills noted by Keith.
“It is my contention that the invention of [agriculture] fundamentally altered the balance between soil production and soil erosion – dramatically increasing soil erosion.
Other researchers, like Jed Kaplan and his team from the Avre Group at the Ecole Polytechnique Fédérale de Lausanne in Switzerland, have affirmed that preindustrial land clearance has had a massive impact on the landscape.
“It is certain that the forests of many European countries were substantially cleared before the Industrial Revolution,” they write in a 2009 study.
Their data shows that forest cover declined from 35% to 0% in Ireland over the 2800 years before the beginning of the Industrial Revolution. The situation was similar in Norway, Finland, Iceland, where 100% of the arable land was cleared before 1850.
Similarly, the world’s grasslands have been largely destroyed: plowed under for fields of wheat and corn, or buried under spreading pavement. The grain belt, which stretches across the Great Plains of the United States and Canada, and across much of Eastern Europe, southern Russia, and northern China, has decimated the endless fields of constantly shifting native grasses.
The same process is moving inexorably towards its conclusion in the south, in the pampas of Argentina and in the Sahel in Africa. Thousands of species, each uniquely adapted to the grasslands that they call home, are being driven to extinction.
“Agriculture in any form is inherently unsustainable,” writes permaculture expert Toby Hemenway. “We can pass laws to stop some of the harm agriculture does, but these rules will reduce harvests. As soon as food gets tight, the laws will be repealed. There are no structural constraints on agriculture’s ecologically damaging tendencies.”
As Hemenway notes, the massive global population is essentially dependent on agriculture for survival, which makes political change a difficult proposition at best. The seriousness of this problem is not to be underestimated. Seven billion people are dependent on a food system – agricultural civilization – that is killing the planet.
The primary proponent of the hypothesis – that human impacts on climate are as old as civilization – has been Dr. William Ruddiman, a retired professor at the University of Virginia. The theory is often called Ruddiman’s Hypothesis, or, alternately, the Early Anthropocene Hypothesis.
Ruddiman’s research, which relies heavily on atmospheric data from gases trapped in thick ice sheets in Antarctica and Greenland, shows that around 11,000 years ago carbon dioxide levels in the atmosphere began to decline as part of a natural cycle related to the end of the last Ice Age. This reflected a natural pattern that has been seen after previous ice ages.
This decline continued until around 8000 years ago, when the natural trend of declining carbon dioxide turned around, and greenhouse gases began to rise. This coincides with the spread of civilization across more territory in China, India, North Africa, the Middle East, and certain other regions.
Ruddiman’s data shows that deforestation over the next several thousand years released 350 Gigatonnes of carbon into the atmosphere, an amount nearly equal to what has been released since the Industrial Revolution. The figure is corroborated by the research of Kaplan and his team.
Around 5000 years ago, cultures in East and Southeast Asia began to cultivate rice in paddies – irrigated fields constantly submerged in water. Like an artificial wetland, rice patties create an anaerobic environment, where bacteria metabolizing carbon-based substances (like dead plants) release methane instead of carbon dioxide and the byproduct of their consumption. Ruddiman points to a spike in atmospheric methane preserved in ice cores around 5000 years ago as further evidence of warming due to agriculture.
Some other researchers, like R. Max Holmes from the Woods Hole Research Institute and Andrew Bunn, a climate scientist from Western Washington University, believe that evidence is simply not conclusive. Data around the length of interglacial periods and the exact details of carbon dioxide and methane trends is not detailed enough to make a firm conclusion, they assert. Regardless, it is certain that the pre-industrial impact of civilized humans on the planet was substantial.
“Our data show very substantial amounts of human impact on the environment over thousands of years,” Kaplan said. “That impact really needs to be taken into account when we think about the carbon cycle and greenhouse gases.”
Restoring Grasslands: a strategy for survival
If the destruction of grasslands and forests signals the beginning of the end for the planet’s climate, some believe that the restoration of these natural communities could mean salvation.
Beyond their beauty and inherent worth, intact grasslands supply a great deal to humankind. Many pastoral cultures subsist entirely on the animal protein that is so abundant in healthy grasslands. In North America, the rangelands that once sustained more than 60 million Bison (and at least as many pronghorn antelope, along with large populations of elk, bear, deer, and many others) now support fewer than 45 million cattle – animals ill-adapted to the ecosystem, who damage their surroundings instead of contributing to them.
Healthy populations of herbivores also contribute to carbon sequestration in grassland soils by increasing nutrient recycling, a powerful effect that allows these natural communities to regulate world climate. They also encourage root growth, which sequesters more carbon in the soil.
Just as herbivores cannot survive without grass, grass cannot thrive without herbivores.
Grasslands are so potent in their ability to pull carbon dioxide out of the atmosphere that some believe restoring natural grasslands could be one of the most effective tools in the fight against runaway global warming.
“Grass is so good at building [carbon rich] soil that repairing 75 percent of the planet’s rangelands would bring atmospheric CO2 to under 330 ppm in 15 years or less,” Lierre Keith writes.
The implications of this are immense. It means, quite simply, that one of the best ways to reduce greenhouse gases in the atmosphere is to move away from agriculture, which is based upon the destruction of forests and grasslands, and towards other means of subsistence. It means moving away from a way of life 10,000 years old. It means rethinking the entire structure of our food system – in some ways, the entire structure of our culture.
Some ambitious, visionary individuals are working in parallel with this strategy, racing against time to restore grasslands and to stabilize Earth’s climate.
In Russia, in the remote northeastern Siberian state of Yakutia, a scientist named Sergei Zimov has an ambitious plan to recreate a vast grassland – a landscape upon whom millions of herbivores such as mammoths, wild horses, reindeer, bison, and musk oxen fed and roamed until the end of the last ice age.
“In future, to preserve the permafrost, we only need to bring herbivores,” says Zimov. “Why is this useful? For one, the possibility to reconstruct a beautiful [grassland] ecosystem. It is important for climate stability. If the permafrost melts, a lot of greenhouse gases will be emitted from these soils.”
Zimov’s project is nicknamed “Pleistocene Park,” and stretches across a vast region of shrubs and mosses, low productivity communities called ‘Taiga’. But until 12,000 years ago, this landscape was highly productive pastures for a span of 35,000 years, hosting vast herds of grazers and their predators.
“Most small bones don’t survive because of the permafrost,” says Sergei Zimov. “[But] the density of skeletons in this sediment, here and all across these lowlands: 1,000 skeletons of mammoth, 20,000 skeletons of bison, 30,000 skeletons of horses, and about 85,000 skeletons of reindeer, 200 skeletons of musk-ox, and also tigers [per square kilometer].”
These herds of grazers not only supported predators, but also preserved the permafrost beneath their feet, soils that now contain 5 times as much carbon as all the rainforests of Earth. According to Zimov, the winter foraging behavior of these herbivores was the mechanism of preservation.
“In winter, everything is covered in snow,” Zimov says. “If there are 30 horses per square kilometer, they will trample the snow, which is a very good thermal insulator. If they trample in the snow, the permafrost will be much colder in wintertime. The introduction of herbivores can reduce the temperatures in the permafrost and slow down the thawing.”
In the Great Plains of the United States and Canada, a similar plan to restore the landscape and rewild the countryside has emerged. The brainchild of Deborah and Frank Popper, the plan calls for the gradual acquisition of rangelands and agricultural lands across the West and Midwest, with the eventual goal of creating a vast nature preserve called the Buffalo Commons, 10-20 million acres of wilderness, an area 10 times the size of the largest National Park in the United States (Wrangell-St. Elias National Park in Alaska).
In this proposed park, the Poppers envision a vast native grassland, with predators following wandering herds of American Bison and other grazers who follow the shifting grasses who follow the fickle rains. The shifting nature of the terrain in the Great Plains requires space, and this project would provide it in tracts not seen for hundreds of years.
In parts of Montana, the work has already begun. Many landowners have sold their farms to private conservation groups to fill in the gaps between isolated sections of large public lands. Many Indian tribes across the United States and Southern Canada are also working to restore Bison, who not only provide high quality, healthy, traditional food but also contribute to biodiversity and restore the health of the grasslands through behavior such a wallowing, which creates small wetlands.
Grasslands have the power to not only restore biodiversity and serve as a rich, nutrient-dense source of food, but also to stabilize global climate. The soils of the world cannot survive agricultural civilizations for much longer. If the plows continue their incessant work, this culture will eventually go the way of the Easter Islanders, the Maya, the Greeks, the Macedonians, the Harrapans, or the Roman Empire – blowing in the wind, clouding the rivers. Our air is thick with the remnants of ancient soils, getting long overdue revenge for their past mistreatment.
The land does not want fields. It wants Bison back. It wants grasslands, forests, wetlands, birds. It wants humans back, humans who know how to live in a good way, in relationship with the soil and the land and all the others. The land wants balance, and we can help. We can tend the wild and move towards other means of feeding ourselves, as our old ancestors have done for long years. It is the only strategy that takes into account the needs of the natural world, the needs for a land free of plows and tractor-combines.
In time, with luck and hard work, that ancient carbon will be pulled from the atmosphere – slowly at first, but then with gathering speed. The metrics of success are clear: a calmed climate, rivers running free, biodiversity rebounding. The task of achieving that success is a great challenge, but guided by those who believe in restoring the soil, we can undo 8,000 years of mistakes, and finally begin to live again as a species like any other, nestled in our home, at peace and in balance, freed at last from the burdens of our ancestors’ mistakes.
