In Amerika würde man sagen, „Not a good look“

Call for papers: HISTORY OF CLIMATE ECONOMICS Details at: journals.openedition.org/oeconomia/19... Editors of the Special Issue Christophe Cassen (CNRS, CIRED Paris) Béatrice Cointe (CNRS, CSI Paris) Antoine Missemer (CNRS, CIRED Paris) Deadline for abstracts : January 15th, 2026

BTW, a Moscow (trinocular) or London/Stockholm/Wien/Istanbul (split platforms + connecting vestibules) approach of having circulation between the two platforms rather than above is really the better design for deep station. Cavern station is just too much volume for nothing.

I'd make the case that Brooklyn and Queens are the two biggest news deserts in the whole country.

Catch me at #AGU25 next week talking about climate uncertainty in projections of climate impacts in two ways! - Wed: uncertainty from the choice of historical obs. used to train impact models, post-process projections - Thur: how systemic GCM biases affect impacts projections in the coming decades

Anyone else going to #AGU25 going to be stuck delayed at JFK T5 for the next many hours? 🙄

Of course, climate system uncertainties mean that a central estimate of 2.7C warming (e.g. under SSP2-4.5) could actually reflect a wide range of 2100 warming outcomes!

I won’t dare to hope but I’ll dare to dream I guess

This composition had eluded me for nearly a decade, but yesterday I was finally able to capture it. A train rolled through just as the Duquesne Incline was crossing over the tracks in #Pittsburgh, creating a picture perfect winter scene. It was worth the hours and hours I've waited over the years.

Climate nerds! Make sure you have the newly updated NMME viewer from U. Miami RSMAS bookmarked! nmme.earth.miami.edu/figures/inde...

But *how* will they #PlowTheSidewalks? With what technology?

As an Austro-Chicagoan (at least for a while), I honestly wish we’d have the *spirit* of Austrian markets over the, like, crappy versions of the food etc. I miss. Like, allow for each neighborhood to have the bars, birria joints, hot dog stands, etc. to set up outside with fire pits in the winter!

This paper provides strong evidence that downzoning is associated with reduced construction and increased spatialized segregation. Don’t do it if you want a more equitable city! Read the whole thing: findingspress.org/article/1474...

What happens when you downzone? Our new open-access research paper in @findingspress.org investigates effects of decades of downzoning in Chicago. Findings: —Downzoned areas added 1/7th of the new units as comparable non-downzoned areas; —Downzoned areas became more white & were more expensive.

Dartmouth is hiring climate science postdocs through the prestigious Provost's Fellowship! Info: apply.interfolio.com/178090 Applications are due February 15, 2026. Come join our collaborative and supportive climate community! Reach out to me ([email protected]) with questions.

The IRI DL is a uniquely valuable resource for NOAA (and more) climate data. Over the last 27 years it had a huge impact (positive!) on my career. So long, and thanks for all the fish!

Looking for a PhD in climate science? Great opportunity to help modernise one of the iconic climate time series - Central England Temperature. Led by @timosbornclim.bsky.social, with myself and Met Office collaborators: www.uea.ac.uk/course/phd-d...

I know BlueSky has problems with humour so just to be clear: I, like everyone else, am aware that postdocs aren't real. I'm not spreading misinformation when I refer to them as if they exist, they're jokes and everyone knows that. Chill, ok?

Thanks to the Illinois’ massive investment in transit, Chicago has a bright transit future, with the dawn coming next year: —50% increase in every-10-min bus routes to 30 citywide —8-minute midday headways on rail lines —24-hour Orange Line service (Red & Blue already have it)

Looking for a #PhD in #ClimateExtremes? We are advertising a project attributing causes of recent #droughts using counter-factual storylines. Based in #Edinburgh, working with Andrew Schurer, me, @gabihegerl.bsky.social, & @edhawkins.org tinyurl.com/5n7b52fr

New paper out in @egu.eu's Climate of the Past together with economists (@mbennedsen.bsky.social @erichillebrand.bsky.social) to apply their rate prediction tools to the Cenozoic stack for detecting the timing and duration of breakpoints. Really fun. @au.dk cp.copernicus.org/articles/21/...

first chinese-built trains in Central Europe about to go live with private operator WESTbahn, which is using them to enable an increase to half-hourly freqs on their Vienna - Salzburg (and beyond) service. (This is on top of the 2-4 tph by the federal railways on the same route)

I know this is a result of construction costs and local opposition to construction impacts limiting investment primarily to existing (often former freight) ROWs ; but its just infuriating how many US cities’ rail networks look like they’re doing their best to avoid the people who would take them

If you are interested in a postdoc position on the Stanford campus on the climate effects of a slowdown/shutdown of the Atlantic Meridional Overturning Circulation, please contact me. Atmosphere or ocean modeling experience is a plus. sustainablesolutions.stanford.edu/people/ken-c...

Climate change DEFINITELY affects hurricane: STRENGTH: Warmer water is hurricane food RAINFALL: Warm air holds more water vapor SURGE: Warmer water expands, warmer ice melts, sea levels rise PREDICTION: hotter seas mean faster intensification

Possibly controversial opinion: Model spread is unconnected to real uncertainty. It can both underpredict (response of ENSO), and overpredict (CMIP6 ECS). Actual uncertainty needs a much more careful assessment of both model structural variations alongside observational constraints & model bias.

Private Austrian rail operator WESTbahn is expanding, starting service on the southern line from Vienna, via the new high speed line between Graz and Klagenfurt. Still making a healthy profit on 2tph from Vienna west to Salzburg (on top of 2-4 tph by the federal railways) wien.orf.at/stories/3326...

He resigned as governor 4 years ago in the face of multiple scandals. He’s shown no contrition whatsoever. He gets a free pass every time a camera is in front of his face, and he’s a carpetbagger on top of it all.

Ok the amount of time and effort saved for uptown folks by being able to catch an upstate-bound train in Harlem (with none of the Penn bullsh) instead of Penn would be lovely. I hope the run times aren’t too much slower than Amtrak…

You've got to love studies like these: New carbon tax paper out in @aeajournals.bsky.social: Macroeconomics. The headline: "I find that carbon taxes reduce emissions as expected but also impair macroeconomic activity." What to make of this, a quick 🧵

A lot of comments on Mars rovers or Moon landings, but it's important to remember that the planet NASA studies most is Earth. This is less about cutting flashy things like moonwalks and more about keeping communities in the dark on climate, weather, agriculture, pollution, natural hazards, and more.

An atmospheric general circulation model you can run on a Python Jupyter notebook?! Heck yeah! Check out this project- both an educational tool for undergraduates/graduate students, and a research tool for scientists interested in idealized climate modeling. journals.ametsoc.org/view/journal...

For so long, fossil fuel projects have said their contribution to climate change is "negligible". Turns out that's wrong. Our research in NPJ Climate Action proves it. Every tonne of CO2 matters. @21stcenturyweather.bsky.social @minderoo.bsky.social #climatechange www.nature.com/articles/s44...

hope EU member states take this historical opportunity to NOT be weird xenophobic loser-monkeys and instead fast-track citizenship for researchers who relocate (as well as for their families)

⚠️new(-ish) paper in Journal of Climate⚠️ i evaluated CMIP6 models' Pacific decadal SST variability and teleconnections... big takeaway is that models under-simulate temporal PDO/IPO variability on decadal timescales, likely affecting precip trends in the Southwest journals.ametsoc.org/view/journal...

All the more reason for a Parigo-style regular feature about MTA news like they have in Paris :p

my takeaway from climate week nyc is that "climate storytelling" is a little too much "we must reimagine our deepest souls in relationship to mother nature and the moral abyss of the polycrisis into which we must now stare" and not enough "ok but get a heat pump"

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....

New transpo infrastructure in London is presented as “unlocking [XX] housing units”, new neighborhoods in Central Europe are planned around tram, subway, s-Bahn lines. Great piece arguing for a similar approach in NYC.

New York City needs more housing, certainly. But where should that housing be located? In a new article in @vitalcitynyc.bsky.social, I argue that New York City—already the most transit-friendly city in the country—can do an even better job focusing its housing in areas near transit 🚇🏘️
