This year is on course to be one of the three warmest ever recorded and could even top the record set in 2016, the United Nations said on Wednesday.

The past six years, 2015 to 2020, are set to make up all six of the hottest years since modern records began in 1850, the UN’s World Meteorological Organization said in its provisional 2020 State of the Global Climate report.

The 2015 Paris Agreement on climate change calls for capping global warming at well below two degrees Celsius above the pre-industrial (1850-1900) level, while countries will pursue efforts to limit the increase to 1.5 degrees Celsius (34.7 Fahrenheit).

“2020 has, unfortunately, been yet another extraordinary year for our climate,” said WMO secretary general Petteri Taalas.

“The average global temperature in 2020 is set to be about 1.2C above the pre-industrial level,” said Taalas. “There is at least a one in five chance of it temporarily exceeding 1.5C by 2024.”
