SNIP: 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 World Meteorological Organization, which based its findings on analysis of leading international datasets, said increases in global temperatures had already had dire consequences, pointing to “retreating ice, record sea levels, increasing ocean heat and acidification, and extreme weather”.

WMO said its research also confirmed data released by the European Union’s climate monitor last week showing that 2019 was the second hottest year on record, after 2016.

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,” WMO chief Petteri Taalas 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 more than 90 percent of excess heat is stored in the world’s oceans, their heat content is a good way to quantify the rate of global warming, WMO said.

Conservationists said the UN agency’s findings were to be expected.

“It is no surprise that 2019 was the second hottest year on record – nature has been persistently reminding us that we have to pick up the pace,” said Manuel Pulgar-Vidal, leader of WWF’s global climate and energy practice, calling for dramatic measures to halt the warming trend.
