But chances are high he's just out to ride the green wave and make money off 'global warming'. And this time, he made it to the news by leaving his car running for a whole hour while holding a speech inside a building:

Green-minded campaigner Al Gore has been left red-faced after being accused of leaving his car running for almost an hour while he gave a lecture on sustainable development.

Gore not being Gore, he turned out to be particularly adamant about the listeners reducing their carbon footprint while he left his rental car running:

His mistake was compounded further by the fact that he had asked his distinguished guests to attend the event by public transport in order to minimize CO2 emissions.

While Gore needed a rental car, instead of using public transport like everybody else? Probably because he is the climate-saving Übermensch, or more likely because he's simply out to make money? It wouldn't be the first time.

If he really claims to be ecologist, then maybe Ms Palin is a communist.
