This election year has seen some of the most extreme weather in the US for some time. Heat records were topped in many cites for a prolonged period. The most devastating drought in decades has ruined crops in a large area of the country.

Both have championed dangerous new methods of drilling for oil and natural gas, and promoted the very dirty tar sands oil from Canada.
