It wasn't record hot, but the year's 58.5 degree average is not much behind the record. The last eight years have been the eight hottest years on record.
Two federal reports Monday highlight 20 extreme weather and climate disasters that cost more than $1 billion each.
While that threshold is important, extreme weather from climate change is hurting people now in their daily lives with about 1.2 degrees Celsius warming, Vose and Schmidt said. Last year, 1.8 billion people in 25 Asian, African and Middle Eastern nations had their hottest years on record, including China, Nigeria, Bangladesh, Iran, Myanmar and South Korea, according to Berkeley Earth.
"Ocean warming, aside from causing coral bleaching and threatening sea life and fish populations, ... is destabilizing Antarctic ice shelves and threatens massive ... sea level rise if we don't act," said study co-author Michael Mann, a Pennsylvania State University climate scientist.
