"Hottest Ocean Temperatures In History Recorded Last Year"

"Ocean heating driven by human-caused climate crisis, scientists say, in sixth consecutive year record has been broken"

"The world’s oceans have been set to simmer, and the heat is being cranked up. Last year saw the hottest ocean temperatures in recorded history, the sixth consecutive year that this record has been broken, according to new research.

The heating up of our oceans is being primarily driven by the human-caused climate crisis, scientists say, and represents a starkly simple indicator of global heating. While the atmosphere’s temperature is also trending sharply upwards, individual years are less likely to be record-breakers compared with the warming of the oceans.

Last year saw a heat record for the top 2,000 meters of all oceans around the world, despite an ongoing La Niña event, a periodic climatic feature that cools waters in the Pacific. The 2021 record tops a stretch of modern record-keeping that goes back to 1955. The second hottest year for oceans was 2020, while the third hottest was 2019."
