If you do not know who Bill McKibben is you need to lean about him. Bill is an environmentalist and writer who writes about global warming, alternative energy, and economics. Nena and I attended his talk on 4/2 at Mt. Holyoke College. It was standing room only as Bill started the talk by telling us he was there to depress us.
Bill is touring the world to let us know how important the number 350 is. 350 parts per million of CO2 in the atmosphere is the upper safe limit for humanity. Right now the measurement is 387 ppm, so we are past the level of CO2 that is safe for us.
Bill, and others, are organizing A Global Day for Climate Action on October 24, 2009. So go to the web site and find out how you can join. Bill is also on FaceBook and Twitter so that you can stay connected.
