The urgency of climate action is even greater now because some recent observations are at or beyond the highest projections of previous reports.

Scientific studies updating the IPCC assessment of 2007 show that more CO2 is being put into the air than ever before. Rates of change of global mean temperature, sea level rise, ice sheet changes in Greenland and the edges of Antarctica, and ocean chemical changes are running at the highest projections of the 2007 IPCC. In February 2009 at the annual meeting of the American Association for the Advancement of Science, Dr. Chris Field of the Carnegie Institute also reported that some major ways that the earth naturally absorbs CO2 were less efficient now, leaving more of the gas in the air. I heard him say that because of all this, we are “on a trajectory of climate… that has not been explored.”

Not every indication of climate is changing this rapidly, but most scientists now predict a 5 degree F or more temperature increase and at least three feet of sea level rise before 2100 if things continue in this way. The changes documented in these website pages and my book occurred during a time of just over one degree of warming.

Every citizen of the world needs to be aware of rapid climate change:

1. Understand the problem, its causes and threats.
2. Let your leaders know the facts and that you expect them to act.
3. Do something today to reduce greenhouse gas output — please Take Action
