Saatiin Ilmatieteen laitoksen johdolla lisää rahaa AMOCin tutkimiseen! 🌊 The Government is funding our research project on the AMOC, led by the Finnish Meteorological Institute! valtioneuvosto.fi/-/1410903/su...

Yesterday, Edition 3 of the State of Carbon Dioxide Removal Report was released. 🚨✅ Chapter 10, led by Sabine Fuss and Abby Lunstrum, provides update of estimated mitigation potentials and costs for various #CDR methods. 🔍🔦 (Brief overview below)

This is great work. The carbon math is that we have to get emissions to net zero quickly & we need CDR AS WELL, and we need nature based solutions. Let’s do those. But folks have used the possibility of nature based solutions as cheat code to delay doing the harder stuff. The thing is, it is not.

Ilmastonpaneelin raportti käsittelee mm. eläintuotannon merkitystä ilmastonmuutoksen hillinnässä. Ilmastomallituloksiemme mukaan eläintuotannosta enimmillään vapautuvat maat voisivat vuoteen 2100 mennessä sitoa hiilidioksidia 250 Gt, mikä vastaisi 6 vuoden nykypäästöjä. doi.org/10.1088/1748...

🚨 The latest Global Carbon Budget 2025 is officially out: doi.org/10.5194/essd... I’m excited to share three major updates particularly relevant to the 🌊 carbon community:

Hi everyone, in the course of NorESM development for CMIP7 - we've had need to do some rapid benchmarking and diagnostics. To this end, I've made a couple of tools which might be useful for the wider community - python ports of ncview and CMAT. /thread/

One frequently sees headlines that X is warming faster than the global average. That's true of nearly everywhere that humans live, but only because humans nearly all live on land. The process of global warming will generally warm land faster than the oceans.

Learn climate physics in Paris! Apply to the ACDC Summer School on Warm Climates of the Cenozoic. I'm giving the opening lectures on the key role of CO2. www.uib.no/en/rs/acdc/1...

We have a pretty good understanding of the differences between GHG emission estimates, but when it comes to some sectors (e.g., land), estimates seem all over the place! Why is this? @wflamb.bsky.social has you covered... essd.copernicus.org/articles/18/... 1/

So... now we can breathe again. Let's talk about ScenarioMIP. The final version is now up on GMD - and there's some changes since the first draft. /THREAD/ gmd.copernicus.org/articles/19/...

How hot is too hot for humans? Not 35C wet-bulb, as long assumed A new study finds: Survival limits vary with age & exposure Sun + dry heat can be just as dangerous as humidity Heatwaves already crossing critical thresholds We’re closer to the edge than we thought www.nature.com/articles/s41...

1/ New research @lut.fi doi.org/10.1016/j.eg... analyses the role of renewable energy and electrification in climate change mitigation pathways from the IPCC AR6 scenario database. Special focus is placed on those scenarios aiming for 1.5 °C or lower targets.

I'm excited to announce this new paper we have in Nature Climate Change, establishing the core principles of a post-growth climate mitigation scenario that can achieve rapid decarbonization and high well-being. nature.com/articles/s41...

Excellent piece on why Science communication matters, and why in many cases we are training the students for a world that has passed. We need to renew how we teach Science and communications about it. sciencepolitics.org/2026/03/18/w...

Are you a young academic working on climate and feel ready for a move? We are recruiting two Assistant/Associate Professors @granthamicl.bsky.social at Imperial College London @imperialcollegeldn.bsky.social (1/6)

“Europe's landscapes over the past more than 20 million years have predominantly been a mosaic: a mixture of grasslands, scrub and woodlands of varying density. A light-filled, flower-rich open woodland shaped by grazing animals as a decisive ecological force—not a dark closed-canopy forest.”

🌳 Puzzled by land-use emissions data? ➡️ The LULUCF Data Hub description paper now in discussion: essd.copernicus.org/preprints/es... 🌍 The Hub is an open-access platform that compiles, harmonizes, and visualizes country-level CO₂ fluxes from land use, land-use change and forestry (LULUCF). 1/

One week until Christmas Eve! 🎄 Here's how the frequency for white Christmases have changed over the last decades in Europe. 📉 Colors show how often there was snow on the ground at Christmas within each 30-year period, from 1951–1980 through 1995–2024.

Olin Asiastudio-podcastin vieraana juttelemassa mahdollisesta Atlantin kiertoliikkeen romahduksesta ja sen vaikutuksista. Paljon asiaa, eikä kaikkea tietenkään muistanut edes kertoa! www.youtube.com/watch?v=lnRC...

I am beyond excited to announce that the applications are now open for the third Amsterdam Complexity School on Climate Change! Come visit a beautiful city, hear from world-renowned experts, and work with passionate individuals on challenges related to climate change. More info: acscc.nl

I will write more about this later, for now just to say our paper has been published today. 10 years after Paris Agreement we can conclusively say we have failed to limit warming to well below 2°C. What next? www.cell.com/one-earth/ab...

Marine CO₂ removal lacks standardized indicators to quantify carbon removed and environmental impacts. This absence of reliable metrics prevents verification, inhibits investment, and blocks entry into carbon trading systems. iopscience.iop.org/article/10.1...

The new UNEP report is out with the latest estimates of 2100 warming outcomes under current policies, NDCs, and net-zero targets. Here is how it compares to both the IPCC scenarios and other estimates (CAT and IEA, who will release their own updates soon!).

One of my staff asked an interesting question today; to what extent companies can #patent the ideas behind 'negative emission technologies'. Their reason for asking was a company filing a patent that covers many aspects of the use of ocean alkalinity enhancement for sequestering CO2.

Like all other CO₂ removal (CDR) techniques, significantly more research is needed over the next few decades to determine whether enhanced rock weathering is a viable method for CDR.

We finally have a new paper out looking at how summary statistics from the AR6 scenario database are highly dependent on the sampling of the database. High profile statistics are often more representative of the model fingerprint, not the physics. www.nature.com/articles/s41... 1/

I made a list (or 'starter pack') of Land Surface Modelers, because that's the kind of thing one does on #bluesky. Please tell your friends and also (v. important) TELL ME if you want to be added. We need more people here! go.bsky.app/Mw4tJ3t

New paper out. In which we helped the folks at the Allen Institute for AI (AI2) show that their climate emulator does a good (though not perfect) job at reproducing E3SMs' response to different SST boundary conditions. 1/ agupubs.onlinelibrary.wiley.com/doi/full/10....

Do you think climate science needs to be better communicated? We do too! That's why we are looking for a climate science communication specialist to join the Technical Support Unit of the IPCC Working Group I. All details can be found here: www.ipcc.ch/2025/09/17/c... Please share!

There are five post-doctoral positions open in FMI @ilmatieteenlaitos.fi. One of them will be situated in our unit, and the topic is about convective storms and severe extreme weather events. Deadline for applications 25.9.2025. valtiolle.fi/en/jobs/post...

NEW STUDY: How much CO2 can we safely store in geological formations? In a new @nature.com study, we cross-check established academic and industry estimates with various risk factors. We find a prudent geological CO2 storage limit that is about 10x smaller. /1

The Department of Energy hired five academics to raise doubts about climate change. 85+ climate experts (organized by @andrewdessler.com) reviewed their report. Our conclusion, detailed in 450 pages of analysis: it is biased, full of errors, and not fit to inform policy making.

Voisikohan vihdoin alkaa uskoa, kun jo kansanmurhatutkimuksen järjestö International Association of Genocide Scholars toteaa, että Israel harjoittaa Gazassa kansanmurhaa?

Kaikki liittovaltion tiederahoitus alistetaan poliittiseen ohjaukseen. Valkoinen talo määrää, että jatkossa varta vasten nimetyt viranomaiset suuntaavat rahoituksen ”hyödylliseen” tutkimukseen. Kuulostaako tutulta? Me Akatemiassa tiedämme, että suurin hyöty syntyy tieteen vapaudesta.
