Look at the green curve at the top of both provided figures: it is a case of impossible use of classical proxies as originally conceived due to an unfortunate choice of study site.
This spooky finding made me find a plan B better than plan A for my past #PhD #research!

Figure 3 in Davtian et al. (2019) Paleoceanography and Paleoclimatology (https://doi.org/10.1029/2018PA003452)
All plotted sedimentary records from the Gulf of Lion, western Mediterranean Sea, cover the 160 to 9 ka BP period.
(a) A sea surface temperature record from an established organic paleotemperature proxy named TEX86, which shows some spooky features.
(b) A very qualitative and imperfect record of terrigenous inputs, which shows many similarities with TEX86 in terms of trends.
(c) A sea surface temperature record from a recent organic paleotemperature proxy named RI-OH, which typically shows the expected behavior over the covered time period.
(d) Another good-looking sea surface temperature record but from the most established organic paleotemperature proxy named UK'37.
(e) A good-looking record from an established inorganic (non-strictly) paleotemperature proxy named d18O, with a reversed y-axis because foraminiferal d18O values decrease when sea temperatures increase.

Figure 4 in Davtian et al. (2019) Paleoceanography and Paleoclimatology (https://doi.org/10.1029/2018PA003452)
Essentially the same caption as for Figure 3 in Davtian et al. (2019) Paleoceanography and Paleoclimatology, but with a focus on the 70 to 20 ka BP period.

"The exceptional mediterranean heatwave continues with anomalies close to 8°C above average."
"This is around 9 standard deviations above normal. 5 is considered an exceptional, once in a several thousand year event. This is EXTREME."

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?

Screenshot taken by Nina Davtian (that's me!).

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.

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...
