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.

Can't believe people are still using the rainbow colour palette in the year 2026 #EGU26

Day 12 of #ClimateAdvent reposts. Birthday edition 🥳🥳 #ForensicAnthropology edition :)

Day 12 of #ClimateAdvent This is the "beach episode". It's my birthday, so we're doing a sneaky self promo episode today. Yesterday we talked about how climate change leads to more people dying. Today we talk about how climate change impacts us after death. Let's go #ForensicAnthropology #SciComm

‘Tis the season..! Go follow the Climate Advent Calendar! 🕯️✨

Chaotic Brain Person@chaoticbrainperson.bsky.social · 2y ago

Welcome. To #ClimateAdvent. Let's go on a journey through all of #climateScience. We'll cover natural variability/why we know it's not that, but us/inequalities surrounding #climateChange /what to do about all of it. You'll find all days below. If you have any questions, ask. #ClimateSky

Day 3 of #ClimateAdvent reposts. Explaining the greenhouse effect on a molecular level in a text based app is still hard. :)

Day 3 of #ClimateAdvent Our model earth gets an atmosphere today. Our model earth is a sphere that absorbs all energy from the sun. All we needed to know yesterday was that there's a global average temperature on it. Wanna know what that is? Roughly -15°C (5°F) So why don't we all freeze to death?🧵

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?

From Copernicus: This shows how the expected date for breaching 1.5C has been creeping ever closer in recent years. The orange date shows the baseline for the extrapolation; the red date shows when 1.5C is breached based on the trend...

On this LAST DAY OF HURRICANE SEASON, an interesting fact. Did you know no tropical cyclone has ever crossed the Equator!? That’s because it’s physically impossible. Storms need “spin” to develop and survive. But at the Equator there is zero spin… 1/

PhD Opportunity! 🚨 Working with Dr Pauline Tedesco on "Submesoscale ocean flows and processes in the Southern Ocean." NERC GW4+ DTP PhD studentship for September 2026. DEADLINE: 8th Jan 2026 Find out more - www.exeter.ac.uk/study/fundin... 🌊🌐🌍🦑🧪 #PhDsky #AcademicSky

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....

I love how being a librarian means I'm learning new things *all* the time. I've got a PhD in oceanography, but this morning I was answering a reference question & learned about ocean spiciness & how seawater can be "spicy" or "minty." 😍 TY to the person who asked about velocities of deep currents. 🌊

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

Press conference room absolutely packed at #COP30 as 20+ ministers gather to call for a roadmap away from fossil fuels to be a key outcome of this summit (Many more countries have expressed their support behind the scenes)

🚨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...

📢Global Carbon Budget 2025📢 Fossil CO2 emissions continue to rise in 2025 while the terrestrial carbon sink recovers to pre-El Niño strength. The key findings are covered in two reports this year: * ESSDD (preprint): essd.copernicus.org/preprints/es... * Nature: www.nature.com/articles/s41... 1/

Good to see that my lectures provide inspiring content 😬 Welcome to BlueSky @aeon--aa.bsky.social !

Aeon@aeon--aa.bsky.social · 9mo ago

was trying all day to come up with something worth posting for the first time here and couldn’t make a decision, so why not kick it off with a self-made meme instead? made this on Monday after my Ocean Modelling lecture 🤠🌊

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)

Gavin Schmidt@climateofgavin.bsky.social · 9mo ago

Finally out! The outcome of a virtual workshop in Feb 2024 with modelers and observationalists to put together data and protocols to include historical changes in ice sheet/ice shelf discharge in CMIP models. Hopefully not too late for some CMIP7 runs! gmd.copernicus.org/articles/18/...

New paper on scientific challenges raised by early-career ocean professionals (ECOPs)

David Shiffman, Ph.D. 🦈@whysharksmatter.bsky.social · 9mo ago

Identifying and addressing the challenges of early-career ocean professionals during the MSEAS conference

Extended hurricane category scale, following Wehner&Kossin, Proceedings of the National Academy 2024: www.pnas.org/doi/abs/10.1... If that scale didn't stop at Category 5 for historic reasons, we would have had several Category 6 tropical cyclones since year 2000.

Quote to remember: “Trees fall naturally in the forest, and chainsaws are not a hoax.”

Was Hurricane Melissa Super Hurricane? Is Category 6 needed? I took a deep dive in my weekend Forbes piece citing @katharinehayhoe.com @michaelemann.bsky.social @bmcnoldy.bsky.social @weatherprof.bsky.social Rheeda walker Let me know your thoughts after reading it www.forbes.com/sites/marsha...

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 🌊

🧊 New research reveals an overlooked Antarctic process that may skew sea level rise projections. ☀️ A team led by Dr @fabiobdias.bsky.social (ACEAS/UNSW) found East Antarctica ice shelves melt in summer bursts as sea ice retreats and warm water flows underneath. 🔗 antarctic.org.au/overlooked-m...

Overlooked melting in East Antarctica could skew sea level rise projections - ACEAS

New research into how East Antarctica’s ice shelves melt reveals future global sea-level rise predictions could be significantly underestimated.

🌊 Ocean warming threatens the viability of 60% of Antarctic ice shelves If global temps stay <2 °C, nearly all 64 ice shelves survive by 2300. But above ~4.5 °C, ocean melt causes 38 shelves to collapse by 2300, risking up to 10 m sea level rise. www.nature.com/articles/s41...

Ocean warming threatens the viability of 60% of Antarctic ice shelves - Nature

The viability of Antarctic ice shelves under low rates and high rates of global warming is modelled to estimate when it will become unfeasible for the ice shelves to maintain their present-day shape.
