2009 is full of promise
I spent a week at the climate change conference in Poznan, and realized the world is in deep trouble and deeper denial. Worse, the denial is now entirely on the side of action. It is well accepted that climate change is a reality. Scientists say we need to cap temperature increases at 2°C to avoid catastrophe, which means capping emissions at 450 ppm. We know global average temperatures have already increased by 0.8°C and there is enough greenhouse gas in the atmosphere to lead to another 0.8°C increase.
