To a single individual, a problem like global warming can seem vast and hopeless. One thing we constantly hear from readers is, "What can I do?"

Well, now you have an answer: Jump. The folks at World Jump Day are trying to sign up 600,000,000 people in the Western hemisphere to jump simultaneously on July 20, 2006, at 7:39:13 PM (Pacific time — you can find your local time on their website).

Why? Well, according to German researcher Hans Niesward and his colleagues at the Department of Gravitationsphysik at ISA/München, if 600 million people jump all at once, the earth could be bumped into a slightly new orbit. The result: Longer daytime hours, a more habitable average global temperature (particularly helpful to developing countries around the equator), and no more global warming!

There’s something so hopeful and slightly melancholy about this. If nothing else, I appreciate it aesthetically.

So, for my part, I’m jumping!
