The summary below is an abridged version of a National Academy of Science paper due August 6. The lead author, Dr. James E. Hansen, has been researching and writing about climate change for decades. His body of work qualifies him as our greatest or one of greatest living scientists. We will continue our walk off of a very high cliff until the threats of climate change are fully recognized and the subject of a massive effort to limit the damage. Hansen is a professor at Columbia University and directs NASA Goddard Institute for Space Studies. He has been a fearless advocate concerning the extreme dangers of climate change at a very real personal cost. Harassment and personal attacks are common for those who can’t handle the truth. We owe Hansen a profound debt of gratitude for his brilliance and personal courage. Michael Collins
