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.“As this latest assessment comprehensively confirms, we have just witnessed the warmest decade on record,” said Michael Mann, a climate scientist at Penn State University. “As other recent reports confirm, we must act dramatically over this next decade, bringing emissions down by a factor of two, if we are to limit warming below catastrophic levels of 1.5C that will commit us to ever-more dangerous climate change impacts.
