3709. E. O. Wilson on the Anthropogenic Sixth Mass Extinction

 By E. O. Wilson, Encyclopedia Britannica, August 3, 2023



A realistic prediction of the future depends upon recognition that humanity originated in Africa by a series of accidents bordering on the bizarre. The unique winning combination was, first, a relatively immense body size, roughly over 10 kilograms, attained by fewer than 1 in 10,000 species in the history of the animal kingdom. Large bodies make possible the evolution of large brains. Add to this our fast, very precise audiovisual communication, where the vast majority of animal species, along with plants and microorganisms, depend on taste and smell.

We alone can think back and forth through time. Language refined into written literacy has allowed us to envelop and dominate the planet. Tragically, Homo sapiens is not prone to be benevolent to the rest of life. We have proceeded to extirpate all those species of organisms that do not provide us with food, shelter, energy, or entertainment. Meanwhile, we are deeply conflicted in our moral reasoning toward nature and among ourselves. The cause for this condition appears to be the multiple-layered nature of the natural selection that shaped our progenitors’ emotional apparatus. Our responses were crafted by a mix of individual selection, defined as competition among members of the same group for status and resources (“selfish” behavior), versus competition between groups that requires cooperation within groups (“altruistic” behavior). Therein lies the curse visited upon humanity. Its most dangerous and seemingly ineradicable consequence is conflict among competing religious faiths as well as among competing religion-like ideologies.

The consequence that causes me greatest personal concern for Earth’s ultimate future is the ongoing mass extinction of the rest of life. We share the planet with a roughly estimated 10 million other species. They are being extinguished at a rate between 100 and 1,000 times faster than before the arrival of our own species. The effect could be the reduction of Earth’s biodiversity to half its present amount by the end of the century. I prayerfully hope that somehow we can slow the extinction rate and avoid a permanent horrific catastrophe for Earth and ourselves, but, as a career-long student of the subject, I am not optimistic. Yet, we must, and soon. To fail will be the folly our descendants are least likely to forgive.

3707. Catastrophic Global Warming and Climate Change: An Overview of the Crisis and How to Stop It

By Kamran Nayeri, August 3, 2026   
Overlap between future population distribution and extreme heat demographic projections to ∼2070. The shaded areas depict regions where minimum average temperature exceeds 29 °C, while the colored topography details the spread of population density.

As I am writing this essay on July 31, 2026, Canada, France, and Spain are all experiencing catastrophic wildfire seasons, but the fires have somewhat different characteristics. The striking common denominator is extreme heat and dryness associated with climate change, interacting with local vegetation, drought, wind, and human ignition sources. As I am writing, the region I live in in northern California is covered with smoke from the Woodside Fire near the Pacific Ocean, which ignited yesterday at 1:30 in the afternoon and is still burning.

In this essay, I will provide basic information from authoritative sources about the catastrophic global warming and climate change these fires exemplify and point to the policies needed to address them. To understand global warming and catastrophic climate change and how to stop them is not an option but a necessity for the survival of humanity and much of life on Earth.

What Is Global Warming and What Causes It?

The atmosphere is currently more than 1 degree Celsius (1.8 degrees Fahrenheit) warmer than preindustrial times.

Scientists attribute the global warming trend to the human expansion of the "greenhouse effect" (Intergovernmental Panel on Climate Change-IPCC, 2022), a warming that results when the atmosphere traps heat radiating from Earth toward space.

Life on Earth depends on energy coming from the Sun. About half the light energy reaching Earth's atmosphere passes through the air and clouds to the surface, where it is absorbed and radiated in the form of infrared heat. About 90% of this heat is then absorbed by greenhouse gases (GHGs) and re-radiated, slowing heat loss to space and causing the atmosphere to warm.

What Are Greenhouse Gases?

Greenhouse gases are a category of gases that absorb heat energy emitted from the planet's surface, and they remain in Earth's atmosphere for a long time (from decades to centuries). Though they make up less than 1% of all air molecules in the atmosphere, GHGs absorb a significant amount of heat energy and re-radiate some of it back toward the surface. They're called "greenhouse gases" because they trap heat near the Earth's surface in a manner somewhat like how a greenhouse allows in the sun’s rays and then holds in the resulting heat

By adding more GHGs, chief among them carbon dioxide and methane, to the atmosphere, humans are causing average global temperature to rise at an unprecedented rate. Earth has warmed up by an average of 0.11°F (0.06°C) per decade since 1850, or about 2°F (1.1°C) in total. Let’s recall this process began with the English Industrial Revolution 1760–1840 and has continued ever since with the spread of industrialization worldwide. 

The most important greenhouse gases, listed in order of their impact on the greenhouse effect, are:Water vapor (H₂O), carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), and ozone (O₃).

Water vapor is the most abundant greenhouse gas, while carbon dioxide is the most significant in terms of human activities and climate change mitigation efforts. While water vapor emissions have been relatively stable over the long term, studies show they have been increasing in recent decades due to global warming and climate change (Allen et al. al, 2022; Dong et al., 2022).

In its Sixth Assessment Report, the Intergovernmental Panel on Climate Change, composed of scientific experts from countries all over the world, concluded that it is unequivocal that the increase of CO2, methane, and nitrous oxide in the atmosphere over the industrial era is the result of human activities and that human influence is the principal driver of many changes observed across the atmosphere, ocean, cryosphere and biosphere.

In recent decades, the average atmospheric concentration of carbon dioxide (CO₂) has been increasing from around 330 parts per million (ppm) in the 1970s to 340 ppm in the 1980s, to 360 ppm in the 1990s, to 380 ppm in the 2000s, to 400 ppm in the 2010, and 420 ppm in the 2020s, with a record high of 442.7 ppm in 2024.  Methane (CH₄) and nitrous oxide (N₂O) have also been showing substantial increases.

If annual emissions continue to increase as rapidly as they have since 2000, climate models project that by the end of this century global temperature will be between 2.7°F (1.5°C) warmer than the 1901-1960 average, and possibly as much as 7.9°F (4.4°C) warmer, which would be catastrophic to humanity and much of life on Earth.

Sources of carbon dioxide emissions are:

  • Fossil Fuel Combustion: This includes burning coal, oil, and natural gas for electricity, heat, and transportation, which is the largest contributor to greenhouse gas emissions globally.
  • Agriculture: Agricultural practices, particularly livestock production, release significant amounts of methane (CH₄) and nitrous oxide (N₂O) due to enteric fermentation and fertilizer use.
  • Deforestation: The clearing of forests for agriculture or urban development reduces the number of trees that can absorb CO₂, contributing to increased atmospheric carbon levels.
  • Industrial Processes: Manufacturing and chemical production release various greenhouse gases, including CO₂ and fluorinated gases, which have a high global warming potential.
  • Waste Management: Landfills produce methane as organic waste decomposes anaerobically, while waste treatment processes can also emit greenhouse gases.

The most basic reason is that fossil fuels, the equivalent of millions of years of plant growth, are the only source of carbon dioxide large enough to raise atmospheric carbon dioxide amounts as high and as quickly as they have risen.

How Does Global Warming Cause Climate Change?

Global warming causes catastrophic climate change by altering weather patterns characteristic of the Holocene geological epoch.  This epoch began approximately 11,700 years ago, following the last glacial period known as the Pleistocene. The Holocene is characterized by a relatively stable climate that has allowed farming and the development of human civilizations. Catastrophic climate change is undermining the stable weather patterns of the Holocene. Some geologists have argued that the Earth has entered the epoch of the Anthropocene (The Age of Humans). Climate change is primarily driven by the greenhouse effect, where gases like carbon dioxide (CO₂) and methane trap heat in the atmosphere. This process enhances the natural greenhouse effect, leading to higher temperatures. As temperatures rise, certain feedback mechanisms, such as reduced ice cover and increased water vapor, further amplify warming. For instance, melting ice reduces the Earth's albedo (reflectivity), causing more solar energy to be absorbed.

Consequences of Global Warming and Climate Change

Global warming and climate change affect virtually every aspect of the Earth system: the atmosphere, oceans, ecosystems, economies, and societies. They cause extreme weather, such as higher temperatures, leading to more frequent and severe hurricanes, droughts, and heavy rainfall. They cause ecosystem disruption: Changes in climate affect biodiversity, leading to shifts in species distribution and habitat loss. This feeds another existential ecological crisis, the Sixth Extinction: Current extinction rates are estimated at 100 to 1,000 times higher than natural background extinction (Ceballos et al., 2018; Cowie et al., 2022; De Vos et.al., 2014). They also cause sea Level rise: Melting polar ice and thermal expansion of seawater contribute to rising sea levels, threatening coastal communities.

Many consequences reinforce one another through feedback loops. Below is a systematic overview with examples.

1. Rising temperatures

Average global surface temperature has risen by about 1.3–1.5°C above pre-industrial levels, although warming varies by region. Examples include record-breaking heat waves in Europe (2022–2025), temperatures above 49°C (120°F) in parts of western North America, and longer and hotter summers in southern Europe and the Middle East.  Consequences include heat-related deaths, lower labor productivity, and greater electricity demand for cooling (causing more GHG emissions).

2. More frequent and intense heat waves

Heat waves are becoming longer, more frequent, and more severe. Examples include India’s recurring spring heat waves, the U.S. Pacific Northwest “heat dome” (2021)Mediterranean heat waves. Consequences include heat stroke, crop damage, infrastructure failures (roads buckling, rail tracks deforming

3. Melting glaciers

Nearly all mountain glaciers are shrinking. Examples include the Alps, Himalayas, Andes, and Alaska. Consequences include reduced freshwater supplies, increased glacier lake outburst floods, and loss of tourism.

4. Greenland and Antarctic ice loss

Massive ice sheets are losing hundreds of billions of tons annually. Consequences include sea level rise lasting centuries and permanent loss of coastal land. Sea level has risen roughly 20–25 cm (8–10 inches) since 1900 and is accelerating. Examples include Miami flooding during high tides, Pacific island nations threatened, and coastal inundation in Bangladesh. Consequences include coastal erosion, saltwater intrusion into groundwater, and displacement of millions.

5. Sea level rise

Sea level has risen roughly 20–25 cm (8–10 inches) since 1900 and is accelerating. Examples: Miami flooding during high tides, Pacific island nations threatened, Bangladesh coastal inundation.  Consequences: Coastal erosion, saltwater intrusion into groundwater, displacement of millions. Sea level has risen roughly 20–25 cm (8–10 inches) since 1900 and is accelerating. Examples: Miami flooding during high tides, Pacific island nations threatened, Bangladesh coastal inundation. Consequences: Coastal erosion, saltwater intrusion into groundwater, displacement of millions.

6. Stronger storms

Warmer oceans provide more energy for tropical cyclones. Examples include Hurricane Harvey, Hurricane Ian, and Typhoon Haiyan. Consequences include greater rainfall, larger storm surges, and more infrastructure damage

7. More extreme rainfall: A warmer atmosphere holds more water vapor. Examples include Germany floods (2021), Pakistan floods (2022), Vermont flooding (2023), Afghanistan flood 2026.  Consequences include flash floods, landslides, and urban flooding

8. More severe droughts

Some regions experience prolonged drying. Examples include the Western United States megadrought, Horn of Africa drought, and Mediterranean drying. Consequences: Crop failures, water shortages, hydroelectric power losses

9. Larger wildfires

Hotter, drier conditions increase wildfire risk. Examples include Canada (2023), Australia's Black Summer (2019–20), and California fires. Consequences: Loss of forests, air pollution, and property destruction.

10. Ocean warming

More than 90% of excess heat enters the oceans.  Examples include heat waves and warmer North Atlantic temperatures. Consequences include Coral bleaching, fish migration, and stronger hurricanes.

11. Ocean acidification

Oceans absorb carbon dioxide, making seawater more acidic. Examples include coral reef acidification and bleaching, and oyster hatcheries in the Pacific Northwest. Consequences include weakened shells, reduced reef growth, and food web disruption.

12. Coral reef collapse

Repeated marine heat waves kill corals. Examples include Great Barrier Reef bleaching and Caribbean reef decline. Consequences: Loss of biodiversity, reduced fisheries, and lower tourism revenue.

13. Permafrost thaw

Frozen soils are thawing across the Arctic. Examples include Siberia, Alaska, and Northern. Consequences include Methane release, infrastructure collapse, and ecosystem changes.

14. Biodiversity loss

Many species cannot adapt quickly enough and die off. Examples: Amphibian declines, Arctic species under stress, and Alpine plants disappearing. Consequences: Local extinctions, simplified ecosystems, reduced resilience.

15. Species migration

Species move toward the poles or higher elevations. Examples include fish moving northward, birds changing migration timing, and insects expanding ranges. Consequences: New ecological competition. Altered food webs.

16. Agricultural impacts

Climate affects yields differently across regions. Examples include wheat losses during heat waves, coffee production moving uphill, and vineyard relocation. Consequences: Lower yields, food price increases, and greater volatility.

17. Water insecurity

Changing precipitation alters water availability. Examples include Colorado River shortages, Himalayan glacier-fed rivers, Cape Town water crisis. Consequences: Competition among agriculture, cities, and ecosystems.

18. Food insecurity

Climate stresses global food systems. Examples include crop failures in East Africa, fisheries decline, and livestock heat stress. Consequences: Higher food prices, increased malnutrition, humanitarian crises.

19. Human health impacts

Climate affects health through multiple pathways. Examples include heat deaths, smoke inhalation, and spread of infectious diseases. Consequences: More cardiovascular illness, respiratory disease, mental health impacts

20. Spread of infectious diseases

Changing climates alter habitats for disease vectors. Examples include Dengue fever expanding, malaria reaching higher elevations, and Lyme disease moving north.

21. Air quality deterioration

Higher temperatures worsen ozone formation and wildfire smoke. Examples include smoke from Canadian wildfires affecting eastern North America, and increased urban ozone episodes.

22. Economic losses

Climate damages infrastructure and reduces productivity. Examples include billion-dollar disasters in the United States, insurance losses, and agricultural losses.

23. Climate migration

People relocate because of environmental change. Examples include Pacific islands, Bangladesh, and the Sahel region.

24. Increased conflict risks

Climate does not usually cause wars directly, but it can intensify existing tensions. Examples include water disputes, farmer–herder conflicts, and resource competition

25. Infrastructure damage

Climate affects transportation, utilities, and buildings. Examples include rail buckling, airport runway damage, and flooded subway systems.

26. Energy system disruption

Climate influences both energy demand and supply. Examples include higher summer electricity demand, reduced hydropower during drought, and transmission failures during heat.

27. Loss of benefits from ecosystems

Natural ecosystems provide benefits that support human well-being. Examples include pollination, water purification, and flood protection by wetlands

28. Cultural losses

Climate threatens places and traditions tied to particular environments. Examples include Arctic Indigenous environmental cultural practices, Pacific island cultural heritage, and historic coastal communities.

29. Financial instability

Climate risks increasingly affect financial systems. Examples include rising insurance premiums or insurer withdrawals from high-risk regions, and declining property values in flood-prone areas.

30. Positive feedback loops

Some climate changes accelerate further warming. Examples include Arctic sea ice loss reducing Earth’s reflectivity (albedo), leading to more heat absorption; thawing permafrost releasing methane and carbon dioxide; and forest dieback reducing carbon storage.

Who Is Responsible?

To stop global warming and catastrophic climate change, let us ask who is most responsible for the emission of greenhouse gases.

The top ten countries responsible for greenhouse gas emissions are as follows:

  • China - The largest emitter, contributing approximately 30% of global carbon dioxide emissions, with around 11.4 billion metric tons in 2022.
  • United States - The second-largest contributor, emitting about 6.3 billion metric tons of carbon dioxide equivalent in 2021.
  • India - Responsible for roughly 3.9 billion metric tons of carbon dioxide equivalent, accounting for about 7% of global emissions in 2021.
  • European Union (EU) - As a collective, the EU member states contribute significantly, though individual country emissions vary widely.
  • Russia - A major emitter to global greenhouse gases.
  • Japan - Known for high emissions due to industrial activities.
  • Germany - One of the largest economies in Europe, contributing notably to emissions.
  • Iran - A significant emitter, largely due to its oil and gas industry.
  • South Korea - High emissions from industrial and energy sectors.
  • Indonesia - Notable emissions primarily from deforestation and land-use changes.

While China is the top polluter, it also has the largest population in the world, 1.4 billion people.

Another way to look at which countries are most responsible for greenhouse gas emissions is to look at the top five countries on a per capita basis. They are Qatar, Kuwait, United Arab Emirates, Bahrain, and Saudi Arabia; all are also major exporters of oil and gas.  

Thus, if two dozen countries of the world are held accountable for greenhouse gas emissions and they stop such emissions, it goes a long way toward stopping global warming.

Why Have World Governments Proved Unable to Stop Greenhouse Gas Emissions?

There is a clear correlation and causation between industrialization and burning fossil fuels, beginning with the English Industrial Revolution 1760–1840, as the following graph shows.

Fossil fuels have been essential for capitalist industrialization due to their role as a primary energy source. Fossil fuels, including coal, oil, and natural gas, have powered industrialization worldwide. Their accessibility and energy density made them the backbone of economic development, facilitating mass production and transportation. Despite being the world leader in the production of renewable technologies, China is still the largest producer and consumer of coal and coal power in the world. China produces approximately 4.8 billion tons of coal per year, over half of the global total.

Governments subsidize fossil fuels. In 2024, globally, explicit (or fiscal) subsidies were $725 billion (0.6 percent of GDP). Implicit subsidies, primarily underpricing of environmental costs, were $6.7 trillion (5.8 percent of GDP), with three-quarters from underpriced air pollution and climate change (Black et al. al, 2025). 

Now, if we consider capitalist competition, once some group of capitalists began utilizing these high-energy sources, others had to follow to remain viable in the market. This has created a cycle of dependency that reinforced their use across industries and countries worldwide.

Thus, fossil fuels have been a fundamental building block of the anthropocentric industrial capitalist civilization, which includes the bourgeois idea of a good life even among the working people. To replace them will require a radical questioning of capitalist modernity and the anthropocentric industrial culture, and the present bourgeois idea of a good life based on consumerism. 

Two economic forces deepen capitalist firms' addiction to fossil fuels. The first is the negative externalities of burning fossil fuels because emissions of greenhouse gases (GHGs) do not factor in the cost of production.  Second is moral hazard, which occurs when a firm or government is protected from the full costs of burning fossil fuels, so firms and governments have an incentive to behave more recklessly or irresponsibly than they otherwise would.

A case in point is the Paris Agreement negotiated by 196 parties at the 2015 United Nations Climate Change Conference near Paris, France. Each government pledged to devise ways to reduce greenhouse gas emissions voluntarily. There was no enforcement mechanism.  Thus, every government had an incentive to let others take steps to reduce greenhouse gas emissions while it continued to pollute. As a result, greenhouse gas emissions increased 9% between 2015 and 2024, driven by rising energy demand from data centers and industrialization, as reported by McKinsey & Company.

What Is to Be Done?

The worldwide spread of capitalism and industrialization required the ever-increasing use of fossil fuels. human population has exploded 800 percent since the start of the use of fossil fuels. Capitalist development requires ever more production and consumption of commodities, increasing global per capita energy usage over time. Life today in a typical city looks profoundly different from daily life in 1820.  Modernity would never have happened without an unprecedented abundance of energy.

Capitalist societies are dependent on evermore economic growth because production is for profit and evermore growth provide ever more mass of profits. However, ever more production will require evermore consumption, regardless of whether it is for human needs. Thus, capitalist economies are dependent on population growth to provide workers (producers) who are also the bulk of the consumers. That is why capitalist politicians promise economic growth and prosperity.

All this make for evermore consumption of fossil fuels and emission of greenhouse gases.

That is why some the U.S. war on Iran is a war for control of the Middle Eastern oil and gas. Even the establishment of Israel was to secure Western imperialism's domination of the Middle East. 

Unless greenhouse gas emissions stop, climate science tells us it can become self-sustaining once one or more tipping points are reached. A tipping point is a critical threshold that, when crossed, leads to large, accelerating, and often irreversible changes in the climate system. If tipping points are crossed, they are likely to have severe impacts on human society and accelerate global warming.

Key climate tipping points include: Greenland Ice Sheet Collapse, West Antarctic Ice Sheet Collapse, as significant melting could lead to accelerated sea-level rise; coral Reef Die-Off, as warming oceans and acidification threaten coral ecosystems, impacting marine biodiversity; Boreal permafrost thaw, which releases methane, a potent greenhouse gas, exacerbating climate change; Monsoon system changes that cause alterations in monsoon patterns can affect water supply and agriculture in many regions.

The only effective method is to force governments to enact enforceable legislation to reduce greenhouse gas emissions and transition to a post-carbon economy and society, and to change our lifestyle in ways to reduce and eliminate greenhouse gas emissions. This is only possible if a politically independent mass movement of working people forces the government’s hand.

However, this has not happened anywhere in the world yet. In the U.S., a main polluter, on September 21, 2014, the People’s Climate March in New York City, with more than 310,000 people and hundreds of contingents, was a great success. The organizers report that 2,807 similar actions took place in 166 countries during that weekend (Nayeri, October 1, 2014). However, the leadership of the movement fell to Bill McKibben, a journalist by profession, who helped organize 350.org, the main organization in the movement to stop global warming. However, McKibben originally believed he could convince the fossil fuel companies to cease production. Later, he offered self-criticism and argued the movement should instead focus on electing politicians who support the transition to renewable energy, which happens to be largely Democratic politicians, to lobby nationally and locally for the same end. He combined this with “direct action” like chaining himself to the gates of a refinery.

Margaret Klein Salamon and Ezra Silk organized The Climate Mobilization, who believed the U.S. needs an emergency mobilization like the effort organized by Franklin D. Roosevelt (FDR) in World War II to transform the U.S. economy. The problem again was that to do so they wanted to rely on capitalist politicians (Nayeri, September 3, 2016). In 2018, Alexandra Ocasio-Cortez was elected to the House of Representatives, and she campaigned for what she called a Green New Deal (GND) to stop global warming and climate change. At the time, she managed to get a large following among the left Democratic Party supporters as well as socialists and ecosocialists. Her GND was built on a left-liberal bourgeois vision and political platform, as I analyzed in detail (Nayeri, March 25, 2019).

Without an independent politically minded working people’s movement, it remains up to individuals to adopt lifestyles that avoid emissions of greenhouse gases. Currently, about 5%-7% of households have rooftop solar photovoltaic systems. In 2026, renewables supply roughly 27-30% of U.S. electricity generation, so the average household’s electricity mix contains about that proportion of renewable energy, although it varies widely state by state, which amounts to about 5% of home energy use. However, the “renewable” sources for this type of energy generation include burning wood, which releases greenhouse gases.

In brief, the U.S. falls very short of any serious effort to stop catastrophic global warming and climate change.   

Ecocentric Socialist Proposal for Fighting Climate Catastrophe 

Currently, mass consciousness about the causes of catastrophic global warming and climate change, and what, if anything, to do about it, is low.  We need to help educate, organize, and mobilize the working people as an independent political force to stop this catastrophe. 

Currently, most of the world's greenhouse gases are emitted by the following countries and the European Union in the order of total emissions: China 27-30%, United States 11-13%, European Union 6-8%, Russia 5%, India 7%, Indonesia 3%, Brazil 3%, Japan 2-3%, Iran 2%. 

Annual snapshots can be misleading because CO₂ lingers in the atmosphere for centuries. If we add up all emissions since the start of the English Industrial Revolution in the mid-1700s, the United States has contributed more cumulative CO₂ than any other nation. The EU (as a 27-country bloc) ranks second, with China in third place. The United Kingdom and India round out the top five

Global CO₂ emissions average just under five metric tons per person per year. However, per capita emissions of oil-producing Gulf states and high-income countries far exceed that average. The United States, Canada, and Australia typically emit between 14 and 18 tons per person annually. China, despite its massive national total, sits closer to 8 tons per person. India remains well below the global average at roughly 2 tons per capita. Each Indian citizen contributes a fraction of what an average American or Australian does.

Clearly, stopping catastrophic global warming and climate change requires a worldwide mobilization of the working people, especially in most countries, to transcend the anthropocentric industrial capitalist civilization in the direction of an Ecocentric Socialist future (see Nayeri, July 4, 2021, May 1, 2022). Here is an outline of an action program for the climate movement in the U.S. which I proposed in 2015 (Nayeri, June 26, 2015). 

For an emissions tax with subsidies to low-income people

The climate movement can enhance its effectiveness by focusing its campaigns on the key countries and the European Union that are responsible for more than 70% of greenhouse gases. Climate Club

Early industrializers in the West and Japan, as well as China, should take the lead because of the former's historic responsibility and the fact that China’s pollution is largely driven by industrial production for the West, which makes China the leading emitter today. The climate movement should demand that they honor and exceed these intentions by creating a Climate Club through adopting meaningful emissions (or, if appropriate, carbon, as in the case of Indonesia because of its forest clearing) taxes with subsidies to low-income people. 

Emissions tariff and Climate Change Assistance Fund

Key to the international success of emissions taxes is that Climate Club countries impose import tariffs on leading emitters who are not yet in compliance. The combination of emissions, tax and import tariffs will benefit any country that joins the Climate Club and make it unfeasible economically not to join it.  All such tariffs should go to a Climate Change Assistance Fund that gives assistance to the countries most affected by climate change and least able to face it alone and to help them transition to a post-carbon economy. 

How to proceed

In sum, I believe it is high time for each organization in the climate movement to discuss this and other policy proposals in their general meetings. What to do about climate change is too important to leave to politicians, bureaucrats, technocrats and business interests who routinely place corporate and economic interests before the health of the planet and all who live on it.

Whenever we plan for protest actions, various participating groups propose demands or slogans close to their own vision. There is usually harmony with the directions and goals of the climate movement.  However, it is time to strive for greater unity by adopting a clear and concise policy of our own on how to combat climate change. 

The policy proposals here will run into opposition by many politicians, bureaucrats, and corporate leaders. However, the climate movement is a political movement precisely because we must overcome such opposition with our ever-more powerful mobilizations and unity in action.  Who else will design and implement solutions to the climate crisis if not the climate movement?  Some of us, including this author, will argue that to resolve the climate and other existential ecological crises, we must transcend the anthropocentric industrial capitalist civilization in the direction of an ecological socialist society.

However, nobody subscribes to the idea that effective policy to combat climate change must wait for the downfall of capitalism. In fact, it is the reverse.  Only through building a mass climate movement can forge and force an effective climate policy in the womb of the existing capitalist world order can we take genuine steps to transcend it. 

We can win the fight to reverse 250 years of greenhouse gas emissions if enough social forces are organized and mobilized in key countries and across the world.  It requires a clear understanding of policies, strategies, and tactics that can achieve our goal.  Of course, we will continue with campaigns to end fracking, tar sands oil, exploration in particularly dangerous locations, coal trains and bomb trains.  But emission taxes with subsidies to low-income people and formation of a Climate Club that imposes import tariffs on major emitting countries and provides assistance to the countries of the Global South to cope with climate change and transition to a post-carbon economy will be a powerful complement that will unify the movement across the world and point the way forward.
