Rosewell, California, will be the largest private estate powered by solar cells. It's part of Republican Senator Arnold Schwarzenegger's Green Revolution. Schwarzenegger has dubbed global warming; "one of the most important issues facing our time". But others, like Senator Jim Inhofe, dismiss rising temperatures as; "the most media-hyped environmental issue of our time." Some even claim that temperatures in the Artic are sinking. But these voices are becoming increasingly marginalised. The White House may have rejected Kyoto but individual states are rushing to cut greenhouse emissions.
