UN warns more extreme weather ahead after hottest decade on record

2019 second hottest year on record

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".
