Past decade hottest on record, ‘much extreme weather’ ahead: UN

The past decade has been the hottest on record, the UN said Wednesday, warning that the higher temperatures were expected to fuel numerous extreme weather events in 2020 and beyond.

“The average global temperature has risen by about 1.1°C since the pre-industrial era and ocean heat content is at a record level,” said Petteri Taalas, head of the UN’s World Meteorological Organization, in a statement.

“On the current path of carbon dioxide emissions, we are heading towards a temperature increase of 3 to 5 degrees Celsius by the end of century.”

“The year 2020 has started out where 2019 left off – with high-impact weather and climate-related events.  Australia had its hottest, driest year on record in 2019, setting the scene for the massive bushfires which were so devastating to people and property, wildlife, ecosystems and the environment,” said Taalas.

“Unfortunately, we expect to see much extreme weather throughout 2020 and the coming decades, fuelled by record levels of heat-trapping greenhouse gases in the atmosphere”.

Scientists at @NASA and @NOAA separately analyze temperature measurements taken at thousands of weather stations, ships and ocean buoys around the globe. Although the records differ slightly due to data processing, they both show a long-term pattern ?? of increasing temperature.

The Arctic is warming more than three times as fast as the globe. Water pooled ?? on the Greenland Ice Sheet this northern summer as ice melted. When ice on land melts into the ocean, it raises sea levels.
