Seas dominate global weather patterns and the climate crisis is causing profound and damaging changes
The world’s oceans were the hottest ever recorded in 2022, demonstrating the profound and pervasive changes that human-caused emissions have made to the planet’s climate.
More than 90% of the excess heat trapped by greenhouse gas emissions is absorbed in the oceans. The records, starting in 1958, show an inexorable rise in ocean temperature, with an acceleration in warming after 1990.
