@clequere.bsky.social is a professor at @uniofeastanglia.bsky.social who studies climate change and the carbon cycle. She's the founding president of France's High Council on Climate and a member of @thecccuk.bsky.social. She's a Fellow of @royalsociety.org, and not amused about our CO₂ emissions.

@frediotto.bsky.social works on the important topic of attributing extreme weather events to human-caused climate change at @wwattribution.bsky.social.

@tjarnikova.bsky.social is a marine biogeochemical modeler at @uniofeastanglia.bsky.social. Her research focuses on the physical and biogeochemical controls of the ocean carbon cycle, including how variability in AMOC affects the biotic and abiotic controls on the North Atlantic carbon sink.

Really excited to be at #OSM26 with colleagues from around the world and also this small baby. I really appreciate @schmidtocean.bsky.social sponsoring childcare -- this sort of infrastructure makes the difference between letting people, especially women, do science and not.

It’s living, not “training a human”. Best case, all the energy used to build and run AI models is in addition to what people need to live and completely unnecessary. Worst case, they’re taking or competing for resources - energy, water, land - that people need to live.

Perhaps it was coincidental timing, but nothing underscores the collapse of the Washington Post like firing most of the Pulitzer prize winning #climate reporters the very same day as their opinion pages publishes a BS screed by climate misinformer Bjorn Lomborg.

Met Office? More like WET OFFICE, amirite? (Sorry, it had to get out somehow.)

🌊 Unlock the Ocean’s Hidden Chemistry! Excited to announce #argopy 1.4.0! 🎉 Now predict nutrients (NO₃, PO₄, SiOH₄) and carbonate variables (AT, DIC, pHT, pCO₂) with CANYON-B and CONTENT models—directly from your #argofloats data. Perfect for @bgc-argo.bsky.social users ! argopy.readthedocs.io

A picture is worth 1000 words... This appeared on the BBC News today, showing the increase in solar electric generation in the UK. Not sure who produced it, but genuinely think this is a genius piece of scientific communication - the construct and choice of colour scale is near-perfect. Chapeau!

Some reflections after returning back from a conference at which I and 20,000 colleagues learned that the Trump administration intends to dismantle #NCAR. This outrage should not happen. deepconvection.substack.com/p/save-ncar

From wildfire warnings to flood forecasts, NCAR's research impacts everyone in America. President Trump's attempt to dismantle it for political vengeance is beyond reckless. We will fight against this dangerous scheme every step of the way.

If you are in the US and you would like to send a message to your elected representative about the proposed dissolution of the National Center for Atmospheric Research, @agu.org makes it easy with a template here: agu.quorum.us/campaign/151... #AGU25

If you do climate research, or if the weather is in any way relevant to your life, the Trump administration's plan to gut NCAR is bad news. (It's also fiscally irresponsible: good forecasts save lives and infrastructure). I am so tired of these stupid, spiteful decisions.

Naive q: I'm new to downloading CMIP data. I want to directly get netcdfs for later processing, not pangeo etc (so get download links to use w wget). The following works, but lots of experiments are missing, though I'm asking for v basic data (wind and sea surface pressure). Anything I'm missing?

I write a quasi-monthly set of notes, for fun. This month I wrote about things like the Global Carbon Budget, essays I've liked recently, and a czech/english command-line reading diary I made. tjarnikova.github.io/cti/202511la...

1/2 We just published the Global Carbon Budget 2025, with a mix of bad news (CO2 emissions continue to grow) and encouraging news (35 countries saw emissions decline over the past decade while growing their economies). Read the highlights in a short article: theconversation.com/the-worlds-c...

A sidequest I had fun with last month: these colourmaps from old Czechoslovak railways posters. Feel free to use them! tjarnikova.github.io/sklad/rail-c...

If you take the time to read the whole Gates memo (which I did), the bulk of the content was mostly solid and encouraging. Really! It was the FRAME that was off--very off, from the first line. And when your framing is off, then how you make decisions and set priorities is off. THAT'S the problem.

New phytoplankton colourmap just dropped (**ignore the edge effects (or tell me how to regrid such that they don't happen))

⭐️Nominate an Impactful Dataset @agu.org invites you to nominate an impactful dataset! 📊Submissions will be considered for inclusion in an upcoming featured commentary published in AGU Advances. Submit nominations by 20 October. docs.google.com/forms/d/e/1F... @agubiogeosciences.bsky.social

I have downloaded the tiny files that were in your national data center and which you were probably hoping no one would touch Forgive me they were all such tiny files and so very slow and yet they added up

NEW: Hundreds of NASA employees have filed a letter of formal dissent. "We are compelled to speak up when our leadership prioritizes political momentum over human safety, scientific advancement, and efficient use of public resources. The consequences for the agency and the country alike are dire."

This important paper passed under the media radar. It analyses a key indicator of the stability of the Atlantic overturning #AMOC, in measured ocean data. It finds that most climate models get this wrong, and thus have an #AMOC that is too stable. 🌊 agupubs.onlinelibrary.wiley.com/doi/full/10....

Here's our new study with @ncas-uk.bsky.social and @ueaenv.bsky.social, looking at how the closing of the ozone hole affects the Southern Ocean’s capacity to take up atmospheric carbon. It's encouraging - the effects of ozone depletion are reversible, but only if greenhouse gas emissions stay low.

This is horrible. I don't even know what to say. Some of our most key polar data. "As a result, the level of services for affected products below will be reduced to Basic—meaning they will remain accessible but may not be actively maintained, updated, or fully supported." nsidc.org/data/user-re...

Speaking of BLOGS, I write a quasi-monthly newsletter about, er, anything that I think about in a given month. Sometimes related to my work as an ocean modeller, usually not. This month I wrote about a dog I met in Edinburgh, among other things. tjarnikova.github.io/cti/202503ch...

I have a very immediate appointment need for a junior PD position as a chapter scientist on the @ipcc.bsky.social Special Report on Climate Change and Cities. Initial appointment will be 6 months so I can appoint immediately but extendable to the two years of the report cycle. (1/2)

What is someone who has worked for the US government as an expert scientist for 25 years supposed to say when a ketamine-addled tech bro demands bullet points about their "work achievements"? "I spent 3 days calibrating an instrument that you wouldn't understand even if you were sober"?

Another friend fired from US federal science today. Their research question was extremely *woke*: "How do we prevent America's wheat crop from being eaten by this invasive insect?" World class American science is being gutted by pathetic, limited men who understand nothing but the profit imperative.

I can independently confirm Wired's reporting here, as I was working with @marisakabas.bsky.social to track down this engineer. Marisa heard that Nikhil Rajpal was given full access to the NOAA system with a NOAA email from sources today. Rajpal has DC roots. His X account is private: x.com/nikrdc

Our group has also had some success downloading data through the wayback machine.

"As a reality check, a team of researchers in the MIT Energy Initiative (MITEI) examined those strategies, and what they found was alarming: The strategies rely on overly optimistic — indeed, unrealistic — assumptions about how much CO2 could be removed by DAC."
