Decade of 'exceptional' heat likely to be hottest on record, experts say

World Meteorological Organization says 2019 is likely to be second or third warmest year ever

The last decade has been one of "exceptional" heat around the world, and was almost certainly the hottest on record, while the oceans have also warmed to record levels and grown markedly more acidic, the World Meteorological Organization has said.

Temperatures for the years from 2010 to 2019 were about 1.1C above the average for the pre-industrial period, showing how close the world is coming to the 1.5C of warming that scientists say will cause dramatic impacts, extreme weather and the loss of vital ecosystems.
