Today the cause in our spotlight is stopglobalwarming.org.

I can hear you asking: "So. What are they all about?"

Just kidding. I think you know. Stopglobalwarming.org is a "virtual march," bringing folks together to raise awareness about the urgency of the global warming problem and the need to solve it now.

How urgent? Let's see. A sampling of headlines from the last couple weeks goes like this:

"North Pole Could be Ice Free This Summer."

"Global warming could cause humanitarian crises, report shows."

"NASA Warming Scientist: 'This is the last chance."

"Extreme weather to increase with climate change."

Uh, yeah. That's pretty urgent.

There's more than 1.1 million marches on board. They need more. I hope you'll add your name.

And if you haven't already, join the i'm Initiative! You can make sure they get a donation every time you IM or send e-mail.

PS: Later today I'm posting a video interview I did with StopGlobalWarming.org's Director of Outreach, Lindsay Guetschow.  Check it out.
