After a brief (ahem) hiatus, the HadCRUT5 global temperature dataset has now been updated to June 2025 by @metoffice.gov.uk @climateuea.bsky.social and @ncas-uk.bsky.social

Very nice essay/review from @dralaaclimate.bsky.social on AI in climate assessments! Thanks to open access and HTML I could read it on my phone on the train! 😀 I hope the big shots who AI everything these days read it too!

Frisch + informativ!

🔬 New paper alert: "The role of artificial intelligence in climate change scientific assessments" @plosclimate.org As #AI adoption accelerates, should @ipcc.bsky.social integrate these tools? Can LLMs (chatbots) communicate findings while maintaining scientific rigour? doi.org/10.1371/jour... 1/9

I'd love to read more about how they calculated these numbers. www.nature.com/articles/s41... #iCanHazPDF

Online chatter suggests that the DOE Climate Change (Denying) Working Group has been disbanded and the report will be withdrawn. 😂 Seems that violating FACA and the Information Quality Acts have consequences. Not seen any official announcement though.

I got a call from CNN who confirmed this with the DOE. The forces of misinformation will play this off as some kind of paperwork issue, but it was really that the report was an indefensible steaming pile of crap. There was no way they would ever be able to respond to the comments.

Hallo #Berlin, morgen Abend ist die Berlin-Premiere von #Sparschwein, eine fantastische (im doppelten Wortsinn) Doku über einen #Klimastreik im Selbstversuch…

If you want to get your simple climate model picked up by IPCC AR7, see below 👇 We have 11 on our radar from the previous round of RCMIP (egusphere.copernicus.org/preprints/20...), plus a few others we found since. Anybody we don't know about please ping me or Alex

🌍📢 Calling all emulator / reduced-complexity / simple climate modelling groups! The next round of the Reduced Complexity Model Intercomparison Project (RCMIP) is starting, and we’d love your feedback.

Having just completed a 3,900 km EV road trip across 3 countries (+Guernsey), I thought some people might be interested in how it went in terms of charging, cost, efficiency, etc. Will be a long 🧵, so mute if not relevant to you. TL;DR: it went really well. 1/ #EV #EVs

SPARSCHWEIN Berlin Premiere im Rahmen von Cine.Austria – Filmkunst aus Österreich. Am 11.9 um 18:00 im Babylon Kino, Rosa-Luxemburg-Straße 30. Gerne an eure Berlinkontakte weiterempfehlen! kulturforumberlin.at/veranstaltun...

Interested to see insights from Tyndall at 25 event tyndall.ac.uk/events/criti... - what have we learnt since 2000 - a little under 1 trillion tonnes of CO2 ago? I’ll be adding my two penn’orth later today - with my transcript posted on climateuncensored.com soon. #Tyndall25UEA #CriticalDecade

Important points made here on color scales for quant variables, not just for maps. 💯 Pet peve of mine: "With colors restricted to one ramp from dark to light there’s a limited amount of contrast available"

EXCITING NEWS! The Climate.us page has officially launched. Here you will be able to read more about us, our plan, updates, see what real people are saying, view our news coverage, and of course find ways to take action. We look forward to your continued support.

"The models now available as open access include [...]" preview.mailerlite.com/y7x9l4x1r1 I'm not sure "open access" is the right term here, I'd use that for papers, but let's take a look how "open" they are licensed ... 🧵 1/N

Liebe Community (<3), ich habe mein Bluesky Passwort wiedergefunden, und stelle nun fest, ich folge hier gerade einmal 61 Accounts. Das sollte natürlich dringend geändert werden. Daher meine Frage an euch: Wem sollte ich folgen? Was sollte ich nicht verpassen? Danke für alle Inspos!

📊 Visual journalism often takes weeks to produce, even though a similar written article may only take a day or two. Jonas Oesch takes a closer look at a typical visual story to uncover why it takes so long to produce and what can be done to speed up the process. nightingaledvs.com/why-visual-j...

Important and rare discussion by @jonasoesch.ch about how much time it takes to produce visual interactives. I'm often wondering the same thing, especially as time drives up costs and financial accessibility. 📊 (👀 of all five strategies to optimize the process, none of them are "give it to AI".)

I heard @cleanpowerdave.bsky.social mention on the @volts.wtf podcast that "sales of oil-powered cars peaked back in 2017. They've been falling for almost eight years now. It's insane", so I've updated my data back to 2015 to show this. robbieandrew.github.io/carsales/

Fact

Interesting excerpt from the US Congress in September 1975, both considering mandating speed governors in all cars and wondering how electric cars should be covered by fuel economy rules. This is part of US response to the first oil crisis of 1973/74. www.congress.gov/bill/94th-co...

A little demo of reactive SQL in Observable Notebooks 2.0, first using (native) DuckDB to bake data from a remote source, followed by DuckDB-Wasm to create and query reactive views in the client. Should be released this week!

🎓 On September 4, we are hosting a new kind of meetup in London which will focus on the use of DuckDB in Science and Education! ⚡️ We still have some spots for lightning talks. If you're working with DuckDB in your research and/or classroom, consider sharing your story! 🔗 duckdb.org/events/2025/...

😃🎉 We are live! Meet the new WLC Scenario Explorer, our open-source tool for interactive exploration of whole life cycle (WLC) emission scenario results on future #buildings and #construction activity in Europe and beyond. Learn how it can help you advance building #decarbonization!

Hm, @taz.de und Nick Reimer, in eurem Artikel zum @expertenratklima.bsky.social Mag ja sein, dass "Ein Klimawissenschaftler ist nicht dabei." - aber mit Julia Pongratz eine Klimawissenschaftlerin? Autorin im IPCC, Global Garbon Budget, UNEP Emissions Gap Report ... taz.de/Fragwuerdige...

Because India and China each have about one-sixth of the global population, it makes sense when comparing per capita emissions to compare to the world excluding each country. robbieandrew.github.io/country/?cou...

🧵THREAD on agri-methane and ‘no additional warming’ Why is it so important to reduce methane (CH4) emissions from agriculture in the near term? What happens when countries like #Ireland use ‘no additional warming’ to set climate targets? PAPER: iopscience.iop.org/article/10.1... (1/18)

Have you been waiting for "Protomaps Terrain"? It's arriving! @mapterhorn.com is an independent project created by @oliverwipfli.ch - a global elevation model built from multiple sources, distributed as a single PMTiles archive

I didn’t realize there’s a Wikipedia page for the climate spiral. 📊 - Came before (2016) the warming stripes (2018) - Also from @edhawkins.org - The idea of a woman, Taran Fæhn - Featured in opening of 2016 olympics - Theres a paper to explain its success en.m.wikipedia.org/wiki/Climate...

A study predicted economic damages from climate change 3x higher than previous assessments. But it was flawed -- all thanks to the data from just one country. I dug into this strange study and the researchers calling it out: www.washingtonpost.com/climate-envi...

… habe ich mich gefragt. Denn: Ist ein Schienennetz nicht etwas „Flächiges“, so dass man auch irgendwie die Netzlänge, die Größe des Landes oder die Bevölkerungsdichte berücksichtigen sollte? Das hab ich mal gemacht. Hier sind drei alternative Darstellungen (mit Daten von 2023). 2/4

Global datasets of black carbon emissions tend to be based on estimates of how much fuel is combusted incompletely. Comparing with actual measurements suggests these datasets have underestimated black carbon emissions in developing countries. 1/3

I do bloody love this chart. Who'd have thought, 20 years ago, that solar would be ~10% of world electricity generation by 2024 - and over 20% in some countries, rising rapidly in others? Definitely not me. When I started this job I hoped to be part of a solution for maybe 1% of global electricity.

🎨🌧️ Testing color palettes for precipitation maps—clarity over chaos. I like option A (inspired by a Washington Post map). Got a better one? Drop it below. And no rainbow palettes—data deserves better than confusion. 🗺️🫠 #rstats #dataviz

Updates today through July for India, Ireland, Italy, as the I's have it.
