If you're at all interested in climate change and its possible effects on the world, then spend some time reviewing the findings of the Stern Review on the Economics of Climate Change issued by Sir Nicholas Stern, The UK's Head of the Government Economics Service and Adviser to the Government.
The presentation and speaking notes are easy places to start, but at least take a look through the table of contents of the 600 page report and get an idea of the scope and depth of what's presented here.
Even though they only account for 2% of global green house gas emissions, the United Kingdom and its government have made a strong statement with this report. Based on my visits and discussions with people there I know they are tuned into this issue way beyond most other locales. This report signifies their intention to take a global leadership role on this issue, and given this report I think many will find it a welcome one.
