It’s wrong to think that we can campaign to stop climate change in the same way we might campaign to end a war. All the evidence says we are well past that stage now. That is, even if by some impossible, magical course of events all carbon pollution on Earth was stopped tomorrow, we’d still be in really, really deep trouble.

So many greenhouse gases have been pumped into the Earth’s atmosphere that we have rushed far past the safe upper limit — the famous 350 parts per million of CO2, the number that climate action group 350.org took for its name.

Today’s level of 400ppm has been enough to trigger the . More than three-quarters of the ice cap’s volume has melted away in the past 30 years.

Along with wrecking the Arctic region’s fragile ecosystem, scientists predict the loss of the ice cap will trigger other events that throw global warming into overdrive. The two biggest of these are the melting of the huge Greenland ice sheet and the release of immense stores of methane gas frozen inside ice-like crystals on the seafloor.

There is alarming evidence that both disastrous events may already be underway.

DANGEROUS WARMING ALREADY HERE

Last year, Greenland’s ice cap was found to be melting at a rate that . Studies cited in the UN’s IPCC report on climate science said in the decade to 2011 compared to the decade before.

The scientist-authored blog Arctic News also reported that recorded . Two weeks ago, researchers announced that 17 million tonnes of methane were venting into the atmosphere from the ocean floor off the coast of East Siberia each year — previously estimated. Methane gas causes up to 100 times more warming than carbon dioxide over a 20-year period.

Even without the methane pulse, the Earth will keep warming. Researchers from released a study on November 24 that said “the carbon dioxide already in Earth's atmosphere could continue to warm our planet for hundreds of years” even if emissions suddenly stopped.

On top of this, world-leading marine scientists warned in October that a climate change-induced may be underway. This is largely due to the warming of the oceans, combined with the acidification caused by carbon dioxide dissolving into the water. The ocean has not been this acidic at any time in the past 300 million years.

All these impacts are underway now, when the Earth has warmed by just 0.8C since industrialisation. Unless emissions fall rapidly, the warming pathway is for a 4C rise — maybe as soon as 2060. That is, business-as-usual puts us on track for global warming five times worse that it is already.

FOSSIL FUEL BINGE

Despite all these findings, the world’s big polluting firms (and the banks that finance them) are engaging in a fossil fuel binge. Last year alone, companies spent $674 billion to new oil, gas and coal deposits.

The International Energy Agency predicts global investment in extracting and processing new fossil fuel reserves will add up to a staggering $22.87 trillion between 2012 and 2035. And because conventional fossil fuel sources are running out, an increasing part of this investment will be in even more polluting unconventional sources: gas and oil fracking, tar sands oil, shale oil, extra heavy crude oil, deepwater offshore oil and energy deposits from the newly accessible Arctic seabed.

US energy analyst Michael Klare put it bluntly in a recent article: “Most of us believe (or want to believe) that the second carbon era, the Age of Oil, will soon be superseded by the Age of Renewables ... There is only one fly in the ointment: it is not, in fact, the path we are presently headed down.

“The energy industry is not investing in any significant way in renewables. Instead, it is pouring its historic profits into new fossil-fuel projects ... The result is indisputable: humanity is not entering a period that will be dominated by renewables. Instead, it is pioneering the third great carbon era, the Age of Unconventional Oil and Gas.”

In a summed up the fearful outcome if the big corporate polluters get their way: “It is not an exaggeration to suggest, based on best available scientific evidence, that burning all fossil fuels could result in the planet being not only ice-free but human-free.”

THREE TYPES OF DENIAL

We are already living in a world of dangerous, irreversible climate change. We need to cut emissions sharply to stop things getting even worse, but we also need to prepare to adapt to the changes that are coming. Radical social change — economic and political systems based on equal access, human solidarity and sustainable production — will be the most important adaptation measure of all.

If we are going to survive in a warmer world, then we must also do so without illusions. The threat of climate change would be a lot less daunting if the mainstream discourse about it were not so dominated by reckless denial, shamefaced excuses and sinister silences.

From the standpoint of humanity having a safe future on this planet, this race to wreck and poison the Earth for profit is insane, even suicidal. Yet for the powerful companies that stand to profit, and from the standpoint of the capitalist system as a whole, it's an entirely predictable response. The methodical destruction of the life-giving properties of our planet is the visible product of “the invisible hand”.

The , held in Bolivia in 2010, drew together more than 20,000 climate campaigners — mostly from the global South. The conference adopted a “People’s Agreement” that concluded capitalism’s “model of limitless and destructive development”, its “regime of production and consumption [that] seeks profit without limits”, is ultimately to blame for the climate crisis.

The People’s Agreement also noted that “the corporations and governments of the so-called developed countries, in complicity with a segment of the scientific community, have led us to discuss climate change as a problem limited to the rise in temperature without questioning the cause, which is the capitalist system”.

As we strive to build mass movements to respond to the climate emergency, we will have to confront the corporate polluter-backed denial of the climate science. But we will also have to confront those who accept the science but deny the economic and social roots of the crisis.

US Marxist John Bellamy Foster says there are . The first kind is the outright, absolute denial of any problem, the “automatic response of corporations generally” when their profits are under threat. It’s the denial made infamous by tobacco companies. It’s the denial of those who blindly insist climate change is not happening, or that humans have no role in it.

The second kind of denial is “a retreat from the first”. It admits the problem, but refuses to admit that the present social system is a fundamental issue. This kind of denial gives rise to environmental solutions that confuse the symptoms with the cause. Typically, those who isolate population size, consumption habits or technological change as the most important climate issues are stuck at this second stage of ecological denial.

Foster says the third kind of denial is “a last ditch-defense” and “the most dangerous [denial] of all”. It’s the denial that admits our environmental problems are a failure of capitalism as it exists, but insists we must try to make capitalism green and sustainable.

“The argument here varies,” says Foster, “but usually begins with the old trope that capitalism is the most efficient economic system possible ... and that the answer to ecological problems is to make it more efficient still by internalising costs on the environment previously externalized by the system.”

It’s the denial that says we can deal with climate change while keeping the social relations of domination, inequality and exploitation that got us into it. It’s the denial that says the best way to protect nature is to turn more of it into marketable commodities. It’s the denial that says capitalism is the potential saviour, when it is the present destroyer.

ECOLOGICAL REVOLUTION

Rejecting these three types of denial leads to embracing a strategy of far-reaching ecological revolution. In the words of the People’s Agreement: “It is imperative that we forge a new system that restores harmony with nature and among human beings. And in order for there to be balance with nature, there must first be equity among human beings.”

This is not the same as just waiting for the revolution to come. The campaigns to keep fossil fuels in the ground and build new, sustainable infrastructure are crucial. The point is that if the climate action movement allows its goals to be shaped by what is permissible in a capitalist economy then it has already failed.

If it refuses to compromise on the things that need to be done then it will ultimately have to confront, and remake, the whole system.

This is an immensely difficult and arduous course. We cannot deny the peril we face. But neither should we deny the revolutionary changes needed for humankind to survive and thrive in the future. To respond to the climate emergency, our politics must be as radical as our reality.
