Sawing Off the Branch on which We Sit

I am a great believer in trees and the commons they form; it seems to me that going beyond preserving them to extend their coverage across the world could help deal with many of the most pressing problems facing mankind: climate change, desertification, water, etc.

It has always struck me as barmy that the contribution that trees make to the planet has not been better quantified; now it has:

The global economy is losing more money from the disappearance of forests than through the current banking crisis, according to an EU-commissioned study.

It puts the annual cost of forest loss at between $2 trillion and $5 trillion.

The figure comes from adding the value of the various services that forests perform, such as providing clean water and absorbing carbon dioxide.

The study, headed by a Deutsche Bank economist, parallels the Stern Review into the economics of climate change.

Think about that, and then think of the continuing destruction of forests around the world - in the Amazon, in Africa, in Indonesia, in Russia. This really is the literal equivalent of sawing off the branch on which the whole of humanity sits....

The Greening - and Maturing - of Boris

Despite previously attacking the Kyoto Protocol - which regulates international carbon emissions - as "pointless" and saying that anxiety over climate change was "partly a religious phenomenon" Johnson now admits that the 2006 Stern review on the issue had convinced him of the need to act. "When the facts change, you change your mind," he said.

How many senior politicians would dare say that (hello ID cards, hello Gordon)? I predict that we will see far less of the buffoonish Boris, and much more of this grown-up, sensible Boris in the future. Future PM, anyone?

Five Stars for the Stern Report

WorldChanging has a splendid review of the Stern Report, giving it an unequivocable thumbs-up. It also pulls out a subtle but important facet: the report's ethics.

Actually, it's important to underscore that the ethics in this report are mostly not arcane -- even though those arcane aspects reflect, I think, a tectonic shift in economics that the Stern Review is helping to solidify. Climate change is forcing economists to think differently. In fact, I think climate change will one day be credited with having knocked some sense into the discipline of economics.

As I've noted many times on this blog, this kind of change is needed in order to understand and appreciate justly all the commons, not just that of the world's atmostphere.

Stern but Fair

The conclusions of the Stern Review will not come as any surprise to readers of this blog:

The scientific evidence is now overwhelming: climate change is a serious global threat, and it demands an urgent global response.

This Review has assessed a wide range of evidence on the impacts of climate change and on the economic costs, and has used a number of different techniques to assess costs and risks. From all of these perspectives, the evidence gathered by the Review leads to a simple conclusion: the benefits of strong and early action far outweigh the economic costs of not acting.

But as I commented before about a similar case, what makes this report so important is that it coming from the establishment, not from groups who would be expected to make statements like that above. It is also meticulous in detailing the situation. Kudos to the UK Government for commissioning it - and for making it freely available.

Despite its portentous message, I find its appearance - and of an increasing number of similar reports - strangely heartening: I can't help feeling that we are close to not one but two tipping points.

The first is catastrophic, when the earth's environmental system is so far out of kilter that it changes dramatically; the second is rather more positive - the moment when enough people get what is going on, and start doing something effective to avert or at least mitigate the effects of the first tipping point.

Maybe I'm just an incurable optimist, but I was particularly pleased to read this point:

The loss of natural forests around the world contributes more to global emissions each year than the transport sector. Curbing deforestation is a highly cost-effective way to reduce emissions; largescale international pilot programmes to explore the best ways to do this could get underway very quickly.

Halting deforestation seems a way not only to slow down global warming, but to address many other issues like species loss and even poverty. I say let's do it. Please?
