If We Fail To Act, We Will

We Cannot Afford To Put Off Change Any Longer. We Have To Get On A New Path Within This New Administration. We Have Only Four Years Left For Obama To Set An Example To The Rest Of The World. America Must Take The Lead.

The Forcings That Drive Long-term Climate Change Are Not Known With An Accuracy Sufficient To Define Future Climate Change.

The Evidence For Human-made Climate Change Is Overwhelming.

Several Times In Earth's History, Rapid Global Warming Occurred, Apparently Spurred By Amplifying Feedbacks. In Each Case, More Than Half Of Plant And Animal Species Became Extinct. New Species Came Into Being Over Tens And Hundreds Of Thousands Of Years. But These Are Time Scales And Generations That We Cannot Imagine.

The Climate Dice Are Now Loaded. Some Seasons Still Will Be Cooler Than The Long-term Average, But The Perceptive Person Should Notice That The Frequency Of Unusually Warm Extremes Is Increasing. It Is The Extremes That Have The Most Impact On People And Other Life On The Planet.
