Johann Hari in his own blog:
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 molest a masseur, 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 of 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.
