Tomorrow, October 24, 2009, people around the world will participate in a global day of action to raise awareness about a very important three-digit number -- 350. That's the number that leading scientists agree is the safe upper limit for carbon dioxide, measured in Parts Per Million (PPM) in our atmosphere.  Here's NRDC's New York office getting into the spirit:

If you're reading this blog, you already know we need to pass strong climate and energy legislation if America is going to curb global warming. Urge your senators to pass a strong climate and energy bill now and join one of the thousands of events tomorrow. You can find an event near you on 350.org or stage your own. Be sure to snap a photo and upload it to the 350.org site. You can see more of NRDC's 350 photos on our Facebook page. Become a fan and show us your creative 350 photo!
