Holiday in the climate emergency. No that’s not AI or edited, just a snapshot I just took with my phone on Lacanau beach in France. What future will this boy grow up in? It is in our hands, but time is running out.

Hi! I'm Chaos. And I'm running a climate science Advent calendar (again). The 25th day is all about "hope" and I would love to get a few comments from people in the climate science/activism space. Maybe @katharinehayhoe.com, @climateadam.bsky.social, @rahmstorf.bsky.social, @edhawkins.org, et al?

A GEOMAR study has revealed that heat accumulated in the ocean may be released once more from the depths of the Southern Ocean, following centuries of atmospheric cooling after the reversal of anthropogenic global warming — possibly as a large “heat burp”— and warm the atmosphere once more.

Southern Ocean’s Heat Storage – a Possible Cause of Future ‘Heat Burps’
20 November 2025 / Kiel. So far, the ocean has helped to buffer global warming by absorbing more than 90 per cent of the excess heat trapped in the Earth system by the anthropogenic greenhouse effect....

The warmest water on the entire planet is sitting ~160E in the Equatorial Pacific & a prolonged Westerly Wind Burst event is about to occur here This will trigger a downwelling oceanic kelvin wave that should destroy La Niña ~3 months from now & begin moving the ocean towards El Niño conditions

🚨Out today, acidification of the California Current🚨 Using corals and models we show regionally amplified acidification, due to the combo of CO2 uptake and remineralisation. This highlights potential risks to productive upwelling zones in an acidifying ocean 🌊🧪⚒️📈 www.nature.com/articles/s41...
Fossil coral boron isotope data used to reconstruct California Current pCO2.  In a non-acidifying ocean, the data should fall on the grey 1:1 line.  Instead they fall below, indicating an acidifying ocean, and show greater acidification at greater depths (symbol colour), consistent with model simulations (dashed lines) - a phenomenon explained on the next figure! Upwelling zones, like the California Current System, experience amplified ocean acidification, as the anthropogenic CO2 taken up in the offshore waters  - which then get subducted and go on to feed the upwelling zone - is added to by carbon from remineralisation.  This means that the upwelling waters end up in a much more carbon-rich part of total alkalinity (TA) versus dissolved inorganic carbon (DIC) space, where CO2 (and pH) contours are much closer together.  The result is that 100 ppm carbon uptake offshore results in a nearshore pCO2 change of 300 ppm.

Happy to see this out! Meltwater can delay future surface warming, and its interannual variations impact ocean stratification & overturning.​​ This effect is usually absent from models. Including it as forcing may lead to more realistic simulation of surface temperature and sea ice trends🧊🌊 (1/7)

When emissions stop, and the world starts to cool, what happens to the heat the ocean has accumulated? Well, let’s say the ocean had a bit too much of a mouthful before, and didn’t have the time to chew properly before swallowing its deep waters 🌊
