Due to the current gap in funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program is pausing most operations effective 12 May 2025. Nearly all staff will be furloughed until funds from our existing NSF grant become available. For more information, see buff.ly/d2TC1Oy
WMO State of the Climate report (spoiler alert: it’s not great).
@hausfath.bsky.social and I have a short article in it looking at the contributions to the temperatures in 2023+2024.

Have you ever heard about PMOC? This is the equivalent of AMOC, but in the pacific and it could emerge to compensate the AMOC weakening.
The IPCC AR7 draft report is public. For those who thinks that climate science is a hoax done behind closed doors, go have a look, we have nothing to hide. #climate #IPCC
I'm surprised that AR7 is done already. Shouldn't it be based on the CMIP7 datasets?
The Arctic is among the most dramatically affected regions on Earth, where the impacts of global warming are unfolding at an unprecedented rate.
Hi Bluesky
I am a research assistant specializing in physical oceanography. After spending 10 years at Fisheries and Oceans Canada, I am now employed at Environment and Climate Change Canada (ECCC), where I work on ocean modeling as part of the Canadian Climate Earth System Model (CanESM).
Our new paper on the inflation of the Arctic Ocean's Beaufort Gyre was published this week.
The gyre inflation in a warming climate implies its increasingly important role for the climate system and marine ecosystem. @natureportfolio.bsky.social @commsearth.bsky.social

Watching and reading the coverage of the LA fires, I was struck by something I've not seen discussed elsewhere.
These fires are a sign of things to come, but not in the sense you're probably thinking.

Excellent video from @simonoxfphys.com.

The LA fire is not just a climate adaptation problem, but a climate communication problem. Communication often done on social media.
Is it the same if we look at the entirety of the water column?
[1/3] À #Halifax, des chercheurs testent une solution innovante : l’alcalinisation artificielle des océans. Depuis 2023, 278 tonnes de brucite ont capté 138 tonnes de CO2. Le port est un laboratoire à ciel ouvert, surveillé pour garantir l'équilibre écologique. #geography #geoengineering
So others study that concluded the opposite, that AMOC had decreased, might have been mislead because they use SST as a proxy for the AMOC circulation?
A study shows that AMOC might have not declined since the 1960s. They use CMIP6 models and reanalisys to come to that conclusion.
Other study that concluded that AMOC gas decreased might have been mislead by using a proxy, SST, that has a lower relationship with AMOC than previously thought.
I find this hilarious 😆.
There is a very interesting article in @nature.com about the Applications of generative #artificialintelligence to influence #climatechange decisions. An example from the article is the image below titled "Deceptive Image Shows Influential Climate Skeptic Planting a Tree."

These are the key facts everyone needs to know about climate change, according to @yaleclimatecomm.bsky.social.
I shared this post across 7 different social media platforms, including FB, LI, Mastodon, Threads, X and Twitter both pre-and post-Musk.
Here's how their engagement stacked up. 🧵
Are there region in the Arctic where this positive feedback loop is more important? I guess where the inflow from the rivers are more important...
Massive piece of work by Laurent Oziel and many #AWI colleagues, conducted within the #COMFORT project:
Laurent conducted future 🌊 Arctic Ocean high-resolution simulations that account for climate change AND carbon & nutrient inputs from rivers & coastal erosion.

The @ipcc.bsky.social #AR7 scoping meeting successfully took place in Kuala Lumpur last week, with more than 230 experts from 70 countries drafting the outlines of the three Working Group contributions to #IPCC's seventh report assessing policy-relevant science on #climatechange.
Yes indeed, interactive ice sheet models would provide better representation of the fresh water inflow not only from Greenland but from Antarctica too. I hope to see them soon in our earth systems models.
Ice shelf behavior is hard to predict but what is the fresh water forcing from Greenland reach by our current high emissions scenarios? Are we even close to 0.6 Sv?
AMOC is one the hardest phenomenon to get right in our model and yet, it is one that can have the biggest impact on climate.
Do we know how the Irminger sites will be affected with the increase of GHG? What are the projected freshwater inflow around Greenland from the current climate models?
One of the biggest questions we get is when will our journals be here. We thank you for your patience.
You can now follow our journals with this starter pack!
New starter pack!
Climate change and fossil fuels affect our health in a myriad of ways. That's why solutions for clean energy, nature, and climate resilience can also be solutions for better health.
These experts + organizations are helping us make those connections ⬇️
Who'd I miss?
Hi,
Can you add me to the feed please?
Thank you.
For me is "How the ocean will react to global warming and for how long?"
That is a very broad question 😅.
This region is greatly influenced by the melting water from the Greenland ice shelf, which is very difficult to model because it behave in a non-linear way. The next generation of earth systems models are going to be better at modeling this phenomenon.
The Arctic is very hard to get right in earth systems models. The ocean, the atmosphere, the sea ice and the ice shelf all interact on each other and one bad parameterized phenomenon can lead to completely wrong answers.
