Oceans are hotter, higher and more acidic, climate report warns
The Hindu
"It is just a matter of time before we see another warmest year on record," Taalas said.
The world's oceans in 2021 grew to their warmest and most acidic levels on record, while melting ice sheets helped push sea levels to new heights, the World Meteorological Organization (WMO) said on Wednesday.
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.
"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 WMO report follows on the latest United Nations climate assessment, which warned that humanity must drastically cut its greenhouse gas emissions or face increasingly catastrophic changes to the world's climate.
The levels of climate-warming carbon dioxide and methane in the atmosphere in 2021 surpassed previous records, the WMO said.
Globally, the average temperature last year was 1.11 degrees Celsius above the preindustrial average - as the world inches closer to the 1.5 C threshold beyond which the effects of warming are expected to become drastic.
Last year's temperatures were tempered slightly compared to 2020 because of the cooling effects of La Nina in the Pacific, though the year was still among the top seven hottest years on record.
