Cancun hopes and fears

I arrive in Cancun on Wednesday, with low expectations but looking forward to seeing friends and participating in several events on climate change and food security on behalf of Oxford based GECAFS ( I wish I felt more optimistic that there will be progress because I would so like Mexico to be able to take some credit for success - I have worked on climate change in Mexico and with Mexican colleagues for many years.

Last night, at a Thanksgiving dinner in Tucson I had the chance to see Cape Farewell voyager and writer Gretel Ehrlich whose latest book - The Empire of Ice - documents the changes in the Arctic and impact on its indigenous peoples. Gretel is very pessimistic about the fate of the Arctic if we do not respond to climate change. We spent some time talking about American politics and the prospects for action on climate change, with Neal Conan (of NPR) urging us to take seriously the anger of those who voted for tea party and republican climate deniers in the recent election. Our host, someone whose family has ranched in the American West for decades, suggested we appeal to the personal inter generational concerns of American families but then that doesn't help when with the recession millions of people are unemployed and angry and are worried about today and not tomorrow.

On Monday the special issue of Phil Trans that Mark New and I edited with Tyndall's Kevin Anderson will come out with its focus on the world at 4 degrees C. It is a reminder of what we will face if we don't make progress in Cancun.

Cancun itself is vulnerable to climate change as ECI DPhil Arnoldo Matus Kramer is documenting in his dissertation in regard to risks of sea level rise and hurricanes. I hope that some of you attending Cancun get a chance to visit outside the hotel zone and see the amazing archaeological sites (such as Tulum or Chichen Itza) which are also reminders of what happens when society faces multiple stresses. The collapse of Mayan civilization in the Yucatan peninsula being a classic example of the intersection of increasing consumption, soil depletion and drought.
