The past decade was the hottest ever recorded globally, with 2019 either the second or third warmest year on record, as the climate crisis accelerated temperatures upwards worldwide, scientists have confirmed.

Every decade since 1980 has been warmer than the preceding decade, with the period between 2010 and 2019 the hottest yet since worldwide temperature records began in the 19th century. The increase in average global temperature is rapidly gathering pace, with the last decade up to 0.39C warmer than the long-term average, compared with a 0.07C average increase per decade stretching back to 1880.

The past six years, 2014 to 2019, have been the warmest since global records began, a period that has included enormous heatwaves in the US, Europe and India, freakishly hot temperatures in the Arctic, and deadly wildfires from Australia to California to Greece.


Last year was either the second hottest year ever recorded, according to Nasa and the National Oceanic and Atmospheric Administration, or the third hottest year, as recorded by the UK Met Office. Overall, the world has heated up by about 1C on average since the pre-industrial era.

  • The consequences of the climate crisis are being felt around the world, including recent widespread flooding across east Africa and wildfires in Australia, the Amazon and Siberia.

Robert Dunn, a climate scientist at the UK Met Office, said that the start of this millennium has been warmer than any comparable period since the industrial revolution.

“A number of extreme events, such as wildfires, heatwaves and droughts, have at least part of their root linked to the rise in global temperature,” he said “The view for 2019 is that climate indicators and observations show that the global climate is continuing to change rapidly.”
