Surge in #OceanHeat is a sign #ClimateChange is accelerating

"The rate of warming in the oceans has more than quadrupled since 1985, suggesting global warming in general has undergone a marked acceleration."

This is very problematic. Alarming data from 1979 to 2024 shows sea surface temperatures reaching historic highs. Recent years have shattered all previous records, indicating a dire escalation in our climate crisis. This threatens vital marine ecosystems and our global climate stability. We need leadership in action now.

The image shows a graph titled "A year of record-breaking ocean temperatures, Daily average sea surface temperature, 1979-2024." It tracks daily average sea surface temperatures between the latitudes of 60 degrees North and 60 degrees South, from 1979 through 2024.

The graph features many lines: each grey line represents the sea surface temperature for one year from 1979 to 2022. The years 2023 and 2024 are highlighted in distinct colors. The 2023 line is in red, showing a consistent trend above the highest temperatures of the previous years, while the 2024 line is in purple, showing temperatures starting higher than 2023 and then peaking even further.

Temperature values are marked on the left y-axis ranging from 19.5°C to 21°C. The x-axis at the bottom represents months from January (J) to December (D).

The key points are marked: the red line for 2023 starts at the highest temperature levels of previous years and continues to rise, with a noticeable margin above the historical maximums. For 2024, the purple line starts high, drops slightly, and then begins a steep increase.

The graph illustrates a clear trend of increasing sea surface temperatures, suggesting significant shifts in climate patterns. The data comes from ERA5, CS3/ECMWF sources.

Ocean temperatures have been steadily rising due to human-caused global warming, which in turn means record hottest years have become increasingly common... #climatechange #climate #ClimateCrisis #globalwarming #greenhousegases #oceantemperatures #environment #elninosouthernoscillation #elnino #energy #climatescience #geography #atmosphere #Temperaturerecords #oceanheat https://theconversation.com/the-heat-is-on-what-we-know-about-why-ocean-temperatures-keep-smashing-records-226115

Have we misinterpreted pre-industrial temperature baseline?

Earth may have warmed on average by at least 1.7°C since pre-industrial times. This suggests we have passed the 1.5°C goal of the Paris Agreement. Says a new study based on gauging ocean temperatures over past centuries, called “sclerosponge thermometry”.

Yep, still at record levels as at 31 Jan 2024

#OceanHeat is a climate factor driving intensity and frequency of extreme weather events

Climate Reanalyzer global daily sea surface temperatures with recent years highlighted. 2024 starts at record levels.

Here is the climate Re-analyzer Sea Surface Temperatures global Anomaly map.
For Australia the blue across northern Australia due to the monsoon. Note elevated marine heatwave in Coral Sea and Tasman Sea. East Coast of Tasmania is particularly feeling effects of marine heatwave affecting ecosystems and putting species at risk of extinction.

Oh Dear... more rain for #Queensland with flash flooding and riverine #flooding likely. Western Queensland with ex-#TCKirrily and SE Queensland can expect isolated falls between 200-300mm.

One of the drivers for more intense rainfall is climate driven #oceanheat producing anomalous #SeaSurfaceTemperatures of 1-3C in the Coral Sea enhancing atmospheric water carrying capacity.

Global Sea Surface temperatures to 7 November, deviation from the mean, now at a new record of 6.08 standard deviations. via Prof Eliot Jacobson

"Today the 60°S-60°N global average sea surface temperature broke through the 6 sigma barrier for the first time, reaching 6.08 standard deviations above the 1982-2011 mean."

"Notes.

1) I use the "1982-2011 mean" because it uses the first 30 years of available data, and a 30-year baseline is the standard.

2) If the distribution was normal (it isn't), then 6.08 standard deviations would be about a 1-in-1.7 billion event.

3) F&%k!"

This new paper maps #OceanHeat #OHC down to 2000m https://www.nature.com/articles/s41467-023-42468-z

It helps me seeing the oceans' topography, how deep they are and stuff. So I added such a map to their Figure 2. Heat storage has not changed over most of the North-East #Pacific, which is in most parts as deep as the deepest Atlantic regions. But the Atlantic has done its bit in servicing our heat storage needs. Why is that? Big OHC in the #Atlantic is even bigger in the South between #Argentina and #Africa where ocean floor also shows most mountain ridges. The North-Eastern half of the Pacific is a level floor and OHC is zero or negative. But strong OHC is midway between New Zealand and Argentina, where the floor has a high mountain range near-perpendicular to the wind flow, much like the Atlantic ridge.
How about #ocean floor topography and size of the water body: flat floors don't create swirls bottom-up, leaving wind as sole mixing tool top-down? The bigger the water area over flat floor, the less OHC?
