I think it was just one of those things that the media get hold of and take to extremes, and with their current focus obviously being the global 'recession'/credit crunch, not many really give a shiit about global warming any more cause they have other 'problems' to worry about. Which all just seems pretty funny to me... and kinda indicates that no one seriously thinks it is as big a problem as has been made out.
All that said, i did like seeing those dongs in oversized 4x4's get charged increasing wankloads in taxes, emission charges and what have you.

Hopefully they'll keep that bit up, those people can afford it anyway.
