Sea surface temperatures departures from the 1991-2020 average around Alaska for the week ending May 10, 2024. Northern Bering Sea mostly below normal and partially sea ice influenced. Eastern Gulf of Alaska warmer than average. Data from OISSTv2.1 courtesy of NOAA/PSL/ESRL. #SST#akwx#Arctic
#ClimateChange: World's #oceans suffer from record-breaking year of heat
50 days have smashed existing highs for the time of year by the largest margin in the satellite era. Planet-warming gases are mostly to blame, but the natural weather event #ElNinno has also helped warm the seas. Recent months have brought no respite, with the sea surface (#SST) reaching a new global average daily high of 21.09C in Feb and March this year, according to Copernicus data. https://www.bbc.com/news/science-environment-68921215#climatecrisis
Sea surface temperature departures from 1991-2020 normal in the high resolution OISSTv2 data from NOAA/PSL/ESRL. Eastern Gulf of Alaska remains warmer than normal, while sea ice influenced areas in the Bering Sea are cooler than normal. #sst#akwx#Arctic @Climatologist49
Why has the sea surface temperature ( #SST ) increased so fast this past year and a half? Are #climate models missing key factors?
The article provides a good overview of some of the compounding effects (SO2 aerosols, #solarcycle 25, #water vapour from the Hunga Tonga #eruption and El Nĩno), but is it enough to explain what’s happening? Either way, it’s an enormous amount of heat.

"The #oceans absorb 90% of the heat trapped by the #CarbonEmissions from the burning of fossil fuels, making it the clearest indicator of global heating.
The ocean surface temperatures in 2023 were “off the charts”, the researchers said. The primary cause was another year of record carbon emissions, assisted by El Niño. Over the whole year, the average temperature was 0.1C above 2022, but in the second half of 2023 the temperature was an “astounding” 0.3C higher."
“We don’t really know what’s going on,” Gavin Schmidt, the director of NASA’s Goddard Institute for Space Studies, told me. “And we haven’t really known what’s going on since about March of last year.” He called the situation “disquieting.”
I'm no authority, to say the least, but from reading and following this subject for a number of years it seems that for decades the oceans have been predictably "heroic" in absorbing atmospheric heat which has been disbursed in their waters so uniformly that it's been virtually unmeasurable. Those days are now over and the seas have reached their limit and can absorb no more without their temperatures rising. #SST#SeaSurfaceTemperature
Mes p'tits Mastoufoux, suite des bilans de fin d'année : les températures de surface des océans !
Là aussi, l'année 2023 se termine. Le voyage "Terra incognita" aura marqué 10 mois sur 12 !!
Ce n'est plus un petit dérapage....
Peut-être la courbe la plus effrayante de l'année.

Sea surface temperatures relative to the 1991-2020 normal in the eastern Bering Sea have increased in recent weeks while the western Bering has cooled (relative to normal). It's going to take a while to dissipate ocean surface heat and get sea ice growth underway. Above normal ocean temperatures north of the Bering Strait outline areas without significant sea ice. Little change in the Gulf of Alaska where #sst remain near to above normal. #akwx#Arctic @Climatologist49@Jdnome@RichThompsonAK
Sea surface temperature departures from 1991-2020 average for the week ending November 24 around Alaska are near to above normal. The southern Bering Sea is especially "warm". The remaining sea ice free areas in the Chukchi Sea also stand out with significantly above average #sst. Data from NOAA/PSL/ESRL. #akwx#Arctic @Climatologist49
