A new report on the costs of adapting to climate change is a wake-up call to the rich world
There's a curious irony at the heart of climate change. We, that is, the rich countries, have largely caused the problem. But we aren't the one who are going to suffer the most because of it.
In fact, one of the main reasons we are as rich as we are is because we have burnt the most fossil fuels. Britain, for example, was the home of the largely-coal-powered Industrial revolution, and because we got an early lead on burning coal, we are not only relatively well off, we also lead the world in historical emissions. In total, throughout history, the British have emitted more carbon per head of population than anyone else.
We're also relatively well protected from the worst impacts of climate change. We're rich enough to pay for the changes to our society that are going to be necessary in the short-to medium term, and for the most part we're in areas of the world less vulnerable to the impacts of climate change, which will fall most heavily on poorer counties.
According to the World Bank, 80% of the economic costs of a changing climate will hit the poorer parts of the world. For example, as the climate changes Central America will become harder hit by more frequent tropical storms, China and Peru face threatened water supplies as glaciers melt away, and island states like the Maldives will be swamped by sea level rise and storm surges. Those countries know what they need to do to adapt, but why should they bear the economic burden for a problem they didn't create? And what about the countries that just can't afford large-scale adaptation?
That's why there's broad, (if vague) agreement that we rich countries should pay the poorer countries to, amongst other things, help them 'adapt' to the effects of climate change on them - maybe improving flood defences, or installing more air conditioning, or building new irrigation systems. Trouble is there's little or no agreement over how much we should stump up, and severe reluctance from the rich countries to part with serious amounts of cash.
But now a new report from a coalition of insurers, banks and consultancies has calculated a startling fact - that climate change could reduce the GDP of less developed countries by up to 19%, by 2030. In other words, climate change could wipe out roughly a fifth of the economies of less developed countries within 20 years.
That's pretty startling. Behind the stats it's clear that having 20% of your economy wiped out means massive hardships for the nations concerned.
It's a good frame for the Copenhagen negotiations over 'climate financing' between rich and poor - either we come up with some serious cash, or we're basically saying "We think it's acceptable that we got rich by creating a problem which is going to destroy the fabric of your society, and we're not going to help you out."
Greenpeace, along with many other organizations from a diverse political spectrum - from Oxfam and Christian Aid to the World Bank via Nicholas Stern - say that at least $140bn a year needs to flow from the rich countries to the rest of the world to help them insulate their societies against the worst impacts of climate change, and to enable them to make the same choices about clean renewable energy that we are able to make.
Personally, I don't see anything less as morally defensible. In fact, I'd hope that we might collectively get it together to manage a bit more.
