The oceans are overheating—and scientists say a climate tipping point may be here
In 2023, the world’s oceans experienced the most intense and widespread marine heatwaves ever recorded, with some events persisting for over 500 days and covering nearly the entire globe. These searing ocean temperatures are causing mass coral bleaching and threatening fisheries, while also signaling deeper, system-wide climate changes.
The world experienced an all-time record of marine heatwaves in 2023, with seawater much warmer than normal. Ninety-six percent of the world's seas and oceans were affected, and the marine heatwaves lasted four times longer than the historical average. This is according to a new study published in the journal Science. Seawater heat has a major impact on the global climate and our weather, but it also has other consequences.
"We have seen an unprecedented increase in the number and intensity of marine heat waves."
