Read here and here. History repeats itself, and climate history is no different. The world's climate follows an up and down natural cycle that humans have little, if any, influence on. During the decades of the 20's and 30's, politicians smartly recognized the natural order of climate events. Eighty plus years later, it's evident that politicians (Lindsey Graham, Barbara Boxer, John, Kerry, etc.) seem to think they have the power to control and change the natural climate order. They still can't. Arrogance is not wisdom.
