UK’s former prime minister, Tony Blair, is joining a group of international experts on climate change in a bid to drive forward efforts to reduce global carbon emissions, UK media reports today. Mr Blair, who will be working pro bono, said his role in the effort is to try to ”guide it politically”.

What is it with all these political drop-outs going green? First Gore, now Blair. Guess we all know what Hillary will be up to after the elections.
