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. 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?
