As in 350 parts per million of carbon dioxide in the atmosphere.
Recently, top climate scientists including NASA's James Hansen, set that level as a "red line" that human society should set as a target to lowering atmospheric CO2. We're already above this critical level of atmospheric CO2, indicating that the problem of climate change is not one of the future, but of the present.
I'm usually no activist, but I understand science, and I believe in the power of science to persuade people to view the world in a dramatically different way. If collective action is your thing (and maybe this is one time when it should be), check out 350.org for ways to get involved.

"I'm struck by the narcissism and banality of so many personal blogs." - Blaise Cronin, Professor and Dean, Information Science, Indiana University. Is corn the most banal thing possible?
