George Bush gave his G8 colleagues a verbal kick in the rear as he left the meeting in Japan:

The American leader, who has been condemned throughout his presidency for failing to tackle climate change, ended a private meeting with the words: “Goodbye from the world’s biggest polluter.”

He then punched the air while grinning widely, as the rest of those present including Gordon Brown and Nicolas Sarkozy looked on in shock.

I haven’t seen the videotape so I can’t confirm that Brown and Sarkozy were actually “shocked.” But I like this take on Bush’s jaunty jab:

Mr Bush, who I imagine is fed up to the back teeth at the preening hypocrisy, moral posturing and downright dishonesty of the Green lobby, has clearly decided that the US is not going to be ashamed of being an industrial nation. The constant calls by various environmental groups for the US and other major states to slash CO2 emmissions by more than a half by tomorrrow afternoon or whatever are unworkable, and they know it. The massive cost of shifting energy sources to supposedly cleaner ones could help to tip parts of the world economy into recession or make the existing slowdown even worse; the push for biofuels, for example, is, arguably, hurting poor people in countries that are traditionally highly dependent on grains etc for basic foodstuffs.
