Climate Change

Drastic Action on Climate Change is Needed Now - and Here's the Plan

The government must go further, and much faster, in its response to the moral question of the 21st century.

It is a testament to the power of money that Nicholas Stern's report should have swung the argument for drastic action, even before anyone has finished reading it. He appears to have demonstrated what many of us suspected: that it would cost much less to prevent runaway climate change than to seek to live with it. Useful as this finding is, I hope it doesn't mean that the debate will now concentrate on money. The principal costs of climate change will be measured in lives, not pounds. As Stern reminded us yesterday, there would be a moral imperative to seek to prevent mass death even if the economic case did not stack up.

But at least almost everyone now agrees that we must act, if not at the necessary speed. If we're to have a high chance of preventing global temperatures from rising by 2C (3.6F) above preindustrial levels, we need, in the rich nations, a 90% reduction in greenhouse-gas emissions by 2030. The greater part of the cut has to be made at the beginning of this period. To see why, picture two graphs with time on the horizontal axis and the rate of emissions plotted vertically. On one graph the line falls like a ski jump: a steep drop followed by a shallow tail. On the other it falls like the trajectory of a bullet. The area under each line represents the total volume of greenhouse gases produced in that period. They fall to the same point by the same date, but far more gases have been produced in the second case, making runaway climate change more likely.

So how do we do it without bringing civilisation crashing down? Here is a plan for drastic but affordable action that the government could take. It goes much further than the proposals discussed by Tony Blair and Gordon Brown yesterday, for the reason that this is what the science demands.
