EPA head Scott Pruitt says global warming may help 'humans flourish'

EPA administrator says 'There are assumptions made that because the climate is warming that necessarily is a bad thing'

Scott Pruitt, the head of the Environmental Protection Agency, has suggested that global warming may be beneficial to humans, in his latest departure from mainstream climate science.

Pruitt, who has previously erred by denying that carbon dioxide is a key driver of climate change, has again caused consternation among scientists by suggesting that warming temperatures could benefit civilization.
