The world's oceans grew to their warmest and most acidic levels on record last year, the World Meteorological Organization (WMO) said on Wednesday (May 18), 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" 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 UN climate assessment, which warned that humanity must drastically cut its greenhouse gas emissions or face increasingly catastrophic changes to the world's climate.
Taalas told reporters there was scant airtime for climate challenges as other crises, such as the COVID-19 pandemic and war in Ukraine, grabbed headlines.
Selwin Hart, UN Secretary-General Antonio Guterres's special adviser on climate action, criticised countries reneging on climate commitments due to the conflict, which has pushed up energy prices and prompted European nations to seek to replace Russia as an energy supplier.
DANGEROUS INCREASE
"We are … seeing many choices being made by many major economies which, quite frankly, have the potential to lock in a high-carbon, high-polluting future and will place our climate goals at risk," Hart told reporters.
On Tuesday, global equity index giant MSCI warned that the world faces a dangerous increase in greenhouse gases if Russian gas is replaced with coal.
The WMO report said levels of climate-warming carbon dioxide and methane in the atmosphere in 2021 surpassed previous records.
Globally, the average temperature last year was 1.11 degrees Celsius above the preindustrial average – as the world edges closer to the 1.5 degrees Celsius threshold beyond which the effects of warming are expected to become drastic.
