Fourteen of the 15 hottest years on record have occurred since 2000, according to the UN World Meteorological Organisation, as rising carbon emissions continue to trap heat and drive climate change.
The WMO’s new analysis narrowly places 2014 as the hottest recorded since 1850, as have recent analyses from other organisations. The WMO analysis is particularly authoritative as it brings together a number of leading temperature records, as well as alternative ways of estimating the warmth of the globe.
The average global air temperatures over land and sea in 2014 were 0.57C above the average of 14.00C for the 1961-1990 reference period. The record temperature was above those in 2005 and 2010, the next hottest years, but only by a small amount which was within the margin of uncertainty in the calculations.
