Earth Hour. All the hype (which generates much unwanted emissions, really) will try to reduce carbon emissions in one hour this Saturday. Try, indeed. It will be dark(er), that is all.
Yeah, yeah. The effort and the thought that counts. It's to make some people feel good about themselves.
A California judge recently put a hold on global warming legislation. But that won't stop the AGW backers to shut off their lights on Saturday for one hour. They need to feel good about themselves after that little speed bump.
