Many world leaders are engaged in talks right now in Copenhagen, Denmark. This is an important opportunity for the world to come together and establish goals for reducing our collective carbon footprint.
The International Day of Action on Climate Change took place Saturday, December 15th in locations all around the globe. In my city, it was a blustery, cold evening, but the people came!!! This photo is of Copenhagen, Denmark’s day of action. This youtube link will bring you to the interfaith climate vigil held in Halifax on December 12th, 2009. http://www.youtube.com/watch?v=mTGkRvPab30

The following excerpt is posted on the 350 site, taken from Bill McKibben’s recent blog post, “The Science of 350, the Most Important Number on the Planet.”
350 parts per million is what many scientists, climate experts, and progressive national governments are now saying is the safe upper limit for CO2 in our atmosphere.
Accelerating arctic warming and other early climate impacts have led scientists to conclude that we are already above the safe zone at our current 390ppm, and that unless we are able to rapidly return to 350 ppm this century, we risk reaching tipping points and irreversible impacts such as the melting of the Greenland ice sheet and major methane releases from increased permafrost melt.
There are three numbers you need to really understand global warming, 275, 390, and 350.
For all of human history until about 200 years ago, our atmosphere contained 275 parts per million of carbon dioxide. Parts per million is simply a way of measuring the concentration of different gases, and means the ratio of the number of carbon dioxide molecules to all of the molecules in the atmosphere. 275 ppm CO2 is a useful amount—without some CO2 and other greenhouse gases that trap heat in our atmosphere, our planet would be too cold for humans to inhabit.
