Economic damage due to climate change could dwarf the Great Depression

This article in the Australian reports on the soon-to-be-released Stern Report that global warming could cost more than either of the world wars or the Great Depression of the 1930s:

Leaked portions of the report from former World Bank chief economist Sir Nicholas Stern warn that global warming could cost trillions of dollars to address.

UK treasurer, Gordon Brown, who commissioned the report, will accept the report's primary recommendation, which calls for the establishment of a global market to trade carbon emissions.

I am currently listening to BBC Five Live which will broadcast Sir Nicholas Stern's official summary of his report later tonight and Tony Blair and Gordon Brown will also comment (don't you love the internet?).
