Global ocean warming continued unabated in 2025 in response to increased greenhouse gas concentrations and recent reductions in sulfate aerosols, reflecting the long-term accumulation of heat within the climate system, with conditions evolving toward La Niña during the year. In 2025, global upper 2000 m ocean heat content (OHC) increased by ∼23 ± 8 ZJ relative to 2024 according to IAP/CAS estimates. CIGAR-RT, and Copernicus Marine data confirm the continued ocean heat gain. Regionally, about 33% of the global ocean area ranked among its historical (1958–2025) top three warmest conditions, while about 57% fell within the top five, including the tropical and South Atlantic Ocean, Mediterranean Sea, North Indian Ocean, and Southern Oceans, underscoring the broad ocean warming across basins. Multiple datasets consistently indicate ocean warming, as measured by 0–2000 m OHC, increased from 0.14 ± 0.03 W m−2 (10 yr)−1 during 1960–2025 to 0.32 ± 0.14 W m−2 (10 yr)−1 during 2005–2025 (IAP/CAS), the latter being consistent with EEI (Earth’s Energy Imbalance) estimates within uncertainties. In contrast, the global annual mean sea surface temperature (SST) in 2025 was 0.49°C above the 1981–2010 baseline and 0.12 ± 0.03°C lower than in 2024 (IAP/CAS; similar in CMA-SST, FY3 MWRI SST, ERSSTv5 and Copernicus Marine data), consistent with the development of La Niña conditions, but still ranking as the third-warmest year on record.

Fourth global mass bleaching of coral reefs underway. More than 54 percent of the world’s coral area has experienced bleaching-level heat stress in the past year, and that number is increasing by about 1 percent per week, says NOAA's Coral Reef Watch scientist Dr. Manzello.
#GreatBarrierReef in Australia is suffering what appears to be its most severe #CoralBleaching event; about a third of the reefs surveyed by air showed prevalence of very high or extreme bleaching, and at least three quarters showed some bleaching.

New study suggests the Atlantic overturning circulation AMOC “is on tipping course”
[If true, perhaps the single worst result of the climate crisis we've seen so far, with dire consequences for northern hemisphere climate and weather, oceanic and terrestrial food chains, agriculture, etc.]

RealClimate: A new paper was published in Science Advances today. Its title says what it is about: "Physics-based early warning signal shows that AMOC is on tipping course." The study follows one by Danish colleagues which made headlines last July, likewise looking for early warning signals for approaching an AMOC tipping point (we discussed it here),
"Is the #ClimateCrisis finally catching up with #Antarctica? Finding the answer has never been more pressing - Our inability to confidently predict sea level rise between an extremely challenging two metres and a civilisation-ending 10 metres is an exemplar of the problem facing researchers"
Andrew Meijers, Oceanographer with British Antarctic Survey, writes in today's #Guardian (07.08.2023); a compelling and chilling read.

"The global #climate is one hugely #complex interconnected system. While the #Antarctic and Southern Ocean are far removed from our daily lives, they play an oversized role in this system and the future climate that concerns humanity now. “Global warming” is really “ocean warming”. The atmospheric temperature change, the 1.5C Paris target we are now perilously near to exceeding, really is only a few percent of our total excess trapped heat. Almost all the rest is in the ocean and it is around Antarctica that it is predominantly taken up. How this uptake may change in the future as winds, temperatures and ice shift is a critical scientific, and human, question.
...
hese last few months have been a turbulent time to be an oceanographer, particularly one specialising in the vast Southern Ocean around Antarctica and its role in our climate. The media has been awash with stories of marine heatwaves across the northern hemisphere, the potential collapse of the Atlantic meridional overturning circulation by mid-century and the record-breaking deficit in Antarctic sea ice emerging this southern winter. Alongside heatwaves and bushfires in North America and southern Europe, flooding in China and South American winter temperatures above 38C, the climate has moved from a “future problem” to a “now problem” in the minds of many."
