Why are the world’s governments bothering? Why are they jetting to Cancun next week to discuss what to do now about global warming? The vogue has passed. The fad has faded. Global warming is yesterday’s apocalypse. Didn’t somebody leak an email that showed it was all made up? Doesn’t it sometimes snow in the winter? Didn’t Al Gore get fat, or something?
Alas, the biosphere doesn’t read Vogue. Nobody thought to tell it that global warming is so 2007. All it knows is three facts. 2010 is globally the hottest year since records began. 2010 is the year humanity’s emissions of planet-warming gases reached its highest level ever. And exactly as the climate scientists predicted, we are seeing a rapid increase in catastrophic weather events, from the choking of Moscow by gigantic unprecedented forest fires to the drowning of one quarter of Pakistan.
Before the Great Crash of 2008, the people who warned about the injection of huge destabilizing risk into our financial system seemed like arcane, anal bores. Now we all sit in the rubble and wish we had listened. The great ecological crash will be worse, because nature doesn’t do bailouts.
That’s what Cancun should be about – surveying the startling scientific evidence, and developing an urgent plan to change course. The Antarctic – which locks off 90 percent of the world’s ice – has now seen eight of its ice shelves fully or partially collapse. The world’s most distinguished climate scientists, after recording like this, say we will face a three to six feet rise in sea level this century. That means the drowning of London, Bangkok, Venice, Cairo and Shanghai, and entire countries like Bangladesh and the Maldives.
And that’s just one effect of the way we are altering the chemical composition of the atmosphere. Perhaps the most startling news story of the year passed almost unnoticed. Plant plankton are tiny creatures that live in the oceans and carry out a job you and I depend on to stay alive. They produce half the world’s oxygen, and suck up planet-warming carbon dioxide. Yet this year, one of the world’s most distinguished scientific journals, Nature, revealed that 40 per cent of them have been killed by the warming of the oceans since 1950. Professor Boris Worm, who co-authored the study, said in shock: “I’ve been trying to think of a biological change that’s bigger than this and I can’t think of one.” That has been the result of less than one degree of warming. Now we are on course for at least three degrees this century. What will happen?
The scientific debate is not between deniers and those who can prove that releasing massive amounts of warming gases will make the world warmer. Every major scientific academy in the world, and all the peer-reviewed literature, says global warming denialism is a pseudo-science, on a par with Intelligent Design, homeopathy, or the claim that HIV doesn’t cause AIDS. One email from one lousy scientist among tens of thousands doesn’t dent that. No: the debate is between the scientists who say the damage we are doing is a disaster, and the scientists who say it is catastrophe.
