Ocean warming is accelerating, not just gradually increasing!

The research indicates that global mean sea surface temperature (GMSST) is rising faster than previously thought. The rate of increase has risen from 0.06 Kelvin per decade (1985-1989) to 0.27 Kelvin per decade (2019-2023). EEA-based model fits the data much better than linear models. Therefore, linear extrapolations of GMSST are likely to underestimate future warming.

(a) Deseasonalised global-mean Earth energy imbalance. Piece-wise linear trend fits are based on combined DEEP-C and CERES data (green, with break point of July 2010) and CERES only (red, with break point at August 2010). (b) Earth energy accumulation (integrated EEI) from combined DEEP-C and CERES.

Chart of the worlds sea surface temperatures by the NOA website. The specific data for January second 2025 is displayed besides the graphs for the years since 1985.

This year started above the temperatures of the last record of the el niño year of 2015, way above the el niño record year of 2023 but below the record year of la niña of 2024. It's 0.57 degrees celsius above the median of 1991 to 2020 and 0.72 above the median of 1982 to 2010.

A world map with the sea temperature variation in colors. Yellow and red for above average, blue and violet for below median temperatures.
While the pacific towards Australia is hotter than normal and except central America is colder, the southern and northern Atlantic is normal, in green colors. In general the equatorial regions of the oceans are hotter and the polar regions are colder than normal. This cold be because of melting ice in those regions.

Are past #ocean #temperature #reconstructions based on #geochemical indicators representative at the #local and #regional scales, as such reconstructions typically rely on a single #sediment core?

Good to see the CR graphs of Sea Surface Temperature are back. The data is still WELL about the mean and the trend is still horrifying, but the numbers are back.

"It is official.
The Mediterranean sea surface temperature has just set a new heat record. The average sea surface temperature for the Mediterranean just hit a staggering +28.15°C. Eighteen out of the top twenty hottest days for the Mediterranean sea surface have been observed in the last thirteen months alone."

Picture earth globe, mostly northern hemisphere: Daily sea surface temperature anomalies OISST V2.1 0.25°x0.25°, 1971-2000 base

Mediterranean sea dark red, Northern seas red to dark red for high temperatures, just some narrow blue lines at some edges around Greenland for low temperatures.

This is the highest temperature observed in this dataset which goes back to 1982. It is extremely likely that this record represents the highest temperature for the basin average over a much longer time scale.
It is not just the Mediterranean... Just take a look at the rest of the oceans around the Northern Hemisphere.
The colours represent sea surface temperature anomaly (red means warmer than average and blue means cooler than average). The average is calculated over a 30 year period from 1971-2000 for the date shown. The information displayed here from OISST incorporates data from satellite, ships, buoys and argo floats.

To provide forecasts on #SeaSurfaceTemperature and #OceanCurrent, the Norwegian Meteorological Institute and the Norwegian Institute of Marine Research developed a model called #Norkyst.

The model assimilate OSI SAF's #Metop-B and #Metop-C Sea Surface Temperature products. 🌡 🌊 🛰

The interaction between the oceans and the atmosphere plays a vital role in shaping the Earth's climate. Changing sea surface temperatures can heat or cool the atmosphere, and changes in the atmosphere can do the same to the ocean surface...

Daily sea surface temperature (SST), data from #NOAA Optimum Interpolation SST (#OISST: https://www.ncei.noaa.gov/products/optimum-interpolation-sst ) - from latitude 60°S to 60°N, global scale.

The SST in 2023 exceeded the previous peaks recorded mostly in 2015, 2016, 2020. In 2024, the SST had peaks even higher than in 2023 - showing a temperature anomaly exceeding the previous years (1981 - 2022) with a prolonged fluctuation for more than a full year.

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.

“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.”

#February2024 was warmest on record globally, making it the ninth month in a row with record temperatures for the time of year, say scientists.
Global #seasurfacetemperature (#SST) are at highest ever recorded, data from EU’s #Copernicus #ClimateChange Service show
Global average temperature for past 12mo highest on record at 1.56C above pre-industrial levels. Above the 1.5C threshold beyond which, over the long term, the worst impacts of #climatecrisis are expected.
