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

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.

The preliminary findings of the State of the Global Climate, an annual publication by the WMO, show that this year is on course to be the second or third warmest since records began.
