2020 one of three hottest years ever recorded: UN

This year is on course to be one of the three warmest ever recorded, the United Nations said on Dec. 2, as the UN chief warned the world was on the brink of "climate catastrophe".

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 (WMO) said in its provisional 2020 State of the Global Climate report.
UN Secretary-General Antonio Guterres said the 2020 report spells out "how close we are to climate catastrophe".

"Apocalyptic fires and floods, cyclones and hurricanes are increasingly the new normal," he said in a speech at Columbia University in New York on the state of the planet.

"Humanity is waging war on nature. This is suicidal. Nature always strikes back - and it is already doing so with growing force and fury."

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 C.

"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 1.2 C above the pre-industrial level.

"There is at least a one in five chance of it temporarily exceeding 1.5 C by 2024."

The WMO said 2020 seemed on course to be the second-hottest year ever.

The years from 2015 to 2020 are therefore individually "likely to be the six warmest on record", the report said.

Temperature averages across the last five years, and across the last 10-year period, "are also the warmest on record", it added.
