World’s oceans at most acidic level in 26,000 years, climate report warns

By Jake Spring

(Reuters) -The world's oceans grew to their warmest and most acidic levels on record last year, the World Meteorological Organization (WMO) said on Wednesday, as United Nations officials warned that war in Ukraine threatened global climate commitments.

Oceans saw the most striking extremes as the WMO detailed a range of turmoil wrought by climate change in its annual "State of the Global Climate" https://mcusercontent.com/e35fa2254c2a4394f75d43308/files/3d2f5b01-11a6-dee2-a42a-13ad5002dc33/1290_Statement_2021_en_1_.pdf report. It said melting ice sheets had helped push sea levels to new heights in 2021.

"Our climate is changing before our eyes. The heat trapped by human-induced greenhouse gases will warm the planet for many generations to come," said WMO Secretary-General Petteri Taalas in a statement.

The report follows the latest U.N. climate assessment, which warned that humanity must drastically cut its greenhouse gas emissions or face increasingly catastrophic changes to the world's climate.
