Water temperatures several degrees above normal span thousands of miles, though they have mostly stopped short of the Pacific Northwest coast. Cool water welling up from the depths is thought to be ...

The Southern Ocean can release stored heat during cooling, creating short-term warming. This discovery shows climate recovery ...

As part of the ongoing effort, a NASA-supported team recently published one of the most detailed maps yet of the seafloor.

Oceans all over the world are experiencing warmer-than-normal temperatures, but waters off the southern U.S. could be on the brink of an ocean heat wave emergency as temperatures rise to unprecedented ...

New research shows that marine heat waves can reshape ocean food webs, which in turn can slow the transport of carbon to the deep sea and hamper the ocean's ability to buffer against climate change.

Measurements analyzed by an international research team led by ETH Zurich show that the global ocean absorbed significantly less CO₂ than anticipated during the unprecedented marine heat wave in 2023.

As atmospheric carbon dioxide levels continue to rise, the ocean plays a crucial role in helping to reduce the full impact of human-driven climate change by absorbing roughly a quarter of the carbon ...

The world’s oceans experienced a staggering amount of warming in 2023, as vast marine heat waves affected 96% of their surface, breaking records for intensity, longevity and scale, according to a new ...

A massive heat wave is hitting the Pacific Ocean from Kamchatka to California. Water temperatures several degrees above normal span thousands of miles, though they have mostly stopped short of the ...

Scientists are mapping urban heat to save lives in overheated cities. Extreme heat doesn’t leave visible damage, but it’s one of the deadliest climate threats, especially in cities, where concrete ...
