James Hansen Quotes
Global warming isn't a prediction. It is happening.
Hansen, James. Storms of My Grandchildren: The Truth About the Coming Climate Catastrophe and Our Last Chance to Save Humanity. Bloomsbury, 2009.
The governor actually believed that global warming was the plot of left wingers. Since 99 percent of all qualified scientists agreed that the earth was experiencing an increase in average temperature and that much of the increase was cause by the actions of humans, Perry had to believe that somehow all these scientists had been coopted, intimidated, and enlisted to perpetrate this hoax. One problem with global warming policy making is that while virtually all scientists agree on the fact, there is disagreement of the extent, the timing and the causes. How many degrees of increase will occur and when? What will be the consequences? When will the changes take place? What proportion is man-made? These answers will come as more research is done, but many politicians are reluctant to do anything without precise estimates of the answers to these questions.
James Edward Hansen is an American adjunct professor directing the Program on Climate Science, Awareness and Solutions of the Earth Institute at Columbia University. He is best known for his research in climatology, his 1988 Congressional testimony on climate change that helped raise broad awareness of global warming, and his advocacy of action to avoid dangerous climate change. In recent years he has become a climate activist to mitigate the effects of global warming, on a few occasions leading to his arrest.
