2017 was the hottest year since global records began that was not given an additional boost by the natural climate cycle El Niño, according to new data. Even without an El Niño, the year was still exceptionally hot, being one of the top three ever recorded.
The three main global temperature records show the global surface temperature in 2017 was 1C above levels seen in pre-industrial times, with scientists certain that humanity’s fossil fuel-burning is to blame.
The data, published on Thursday, means the last three years have been the hottest trio ever seen, with 2017 ranking second or third depending on the small differences between the temperature records. Furthermore, 17 of the 18 hottest years recorded since 1850 have occurred since 2000.
2017 also saw extreme weather events strike across the world, from hurricanes in the US and Caribbean to heatwaves in Australia and devastating floods in Asia. Many of these events have been shown to have been made much more likely by the heat resulting from global warming.
