UN warns of ‘much extreme weather’ ahead

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

The World Meteorological Organisation, which based its findings on analysis of leading international datasets, said it also confirmed data released by the European Union’s climate monitor last week showing that last year was the second hottest on record, after 2016.

“The year 2020 has started out where 2019 left off – with high-impact weather and climate-related events,” WMO chief Petteri Taalas said in a statement, pointing in particular to the devastating bushfires in Australia.

“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,” he said. The UN agency said that average global temperatures during both the past five-year (2015-2019) and 10-year (2010-2019) periods were the highest ever recorded.

“Since the 1980s each decade has been warmer than the previous one,” the UN agency said in a statement, warning that “this trend is expected to continue”. The United Nations said last year that man-made greenhouse gas emissions needed to tumble 7.6 percent each year to 2030 in order to limit temperature rises to 1.5C – the more ambitious cap nations signed up to in the landmark Paris climate deal. Current pledges to cut emissions put Earth on a path of several degrees warming by the end of the century.
