U.S. agencies say 2015 was hottest on record, shatters records
Last year's global average temperature was the hottest ever by the widest margin on record, two U.S. government agencies said on Wednesday.
"2015 was remarkable even in the context of the larger, long-term warming trend," said Gavin Schmidt, director of NASA's Goddard Institute for Space Studies.
"This announcement should put pressure on governments to urgently implement their commitments to act against climate change," said Bob Ward, policy director of the Grantham Research Institute on Climate Change and the Environment in London.
