The original cars with their much larger restyling versions issued years later [📹 roma_urraco] Original post

JUST RELEASED: 14 million battery-electric cars sold globally in 2025 says @iea.org. China: 8.2m. Europe: 2.9m (28% of new cars). Norway: 97%. US flat at 1.2m. In 2015 the world sold 330,000 BEVs. Ten years later, 14 million. Long-read coming on Bright Spots 👇 janrosenow.substack.com

A hot bank holiday weekend perhaps hottest on record becomes clear. I am >90% sure we’ll see 30C broken in capital, it will be first time since 2005. I would also give a 50% chance we see record high May temperatures. Heathrow’s oldest record of 31.7C from May 1953 to beat.

A number of wildfires going up in Southern California this evening.

Just a quick look at a cross-section of temperature trends in the lower atmosphere during the month of May. The bottom of the y-axis is the lower troposphere, and the upper portion is reaching into the stratosphere. The x-axis is latitude. Data is provided by ERA5.

Late night seeing #GuySebastian and #SamFischer 😵‍💫 both alway excellent in concert.

Very interesting paper teasing out the nuances of flood risk distribution in the US using an incredible individual-level dataset. Documents a huge concentration of flood risk among the very highest income group - lots of wealthy people enjoying the coast and river views from their second homes.

Subsequent work by the #PAGES2k team of ~80 scientists around the world using expanded data and refined methods produced the most authoritative reconstruction to date (www.nature.com/articles/nge...). It was virtually indistinguishable from the #HockeyStick:

I have total forcing, based on Forster et al 2023 (I havent updated). Not sure how comparable, re, definitions etc You were thinking CO2 only? Or all components? (I would have to look later)

Back in 2012 we did a figure comparing historical emissions to previous generations of emission scenarios. rdcu.be/brDGx Surprisingly, the figure is still doing the rounds. We update it every year, with many interesting changes primarily due to revisions in land-use change emissions. 1/

The weekly Nino 3.4 relative anomaly is now up to +0.5C. Just 8 weeks ago it was -0.6C.

Monster tornado-warned storm near Minneapolis, KS. #kswx

Exceptional heat wave in Central Asia,coming from Iran,where record heat has persisted for weeks. Max Temperatures up to 42C and extraordinary Minimums up to 31C in UZBEKISTAN with the hot air moving East towards China again next days. One after another...

Even fresh May snow cannot hide the irreversible damage caused to the Bossons Glacier by human-induced global warming! ❄️🧊🔥 📷 by @lomdumtblanc.bsky.social

AFRICA HEAT WAVE -17 May 46.8 Tragen LIBYA 46C in Algeria,Chad,Niger,Egypt. Scorching hot nights Mins 30/35C. Min 32.6C at Tinalkoun,ALGERIA is a new May record of High Minimum Next days the heat will move East To Egypt and Sudan with historic high temperatures.

16th May 2026 Tail end of a tornadic supercell near Goodland, KS then dust at Oakley, then an amazing lightning show!!

INDIA RECORD HEAT Another Record in India: Tonight the Minimum Temperature of 32.6C at Chittorgarh was the hottest night ever recorded in the city,matching that of 7 June 2011. More records are on the way.

EXTRAORDINARY 42.6 again at Choluteca HOTTEST DAY IN HISTORY HONDURAS HOTTEST MAY DAY EVER Hundreds of records being broken every day from Mexico to Colombia for weeks. Never happened anything like this or even close.

NEW ANALYSIS: Do renewables make electricity cheaper or more expensive? I pulled together wholesale and retail data across Europe and the US. Wholesale prices track gas exposure, not renewables share. Retail prices barely track either. Read full piece👇 janrosenow.substack.com/p/do-renewab...

Warm humid hike across #Kunanyi #MtWellington #Tasmania . Nice weather but it should be cold not warm 🥵

Hi Bluesky 👋 I finally deleted my X/Twitter account today after years of going back and forth about it. Walking away from nearly 4k followers was honestly terrifying. Washington photographer obsessed with wildlife, ferries, storms, and dramatic Pacific Northwest light ❤️

(Likely) El Nino update for Alaska.

Outlooks recently updated from the multi-model system run at Copernicus are pushing for a spring positive IOD event, though mostly from warmer conditions off Africa. climate.copernicus.eu/charts/packa...

Been seeing a lot of such graphs in recent years 😬 #BraveNewWorld

Every year now, the pre-monsoon heat (the hottest time of year in South Asia with temperatures well over 40°C) starts earlier & lasts longer - due to human-induced climate change - exposing 1billion people to deadly heat. @wwattribution.bsky.social www.worldweatherattribution.org/climate-chan...

Fire starter storms. Lightning started multiple fires in SW Kansas. There is a trail of fires at least 60 miles long from these storms. 14th May 2026

Our record warm autumn rolls on with another warm sunny day. The weather is perfect, but geez could do with some rain 😬#Tasmania

Controversial take: Eurovision is awful. Always has been. I will not be taking questions at this time.

The latest El Nino strength probability outlook from NOAA's Climate Prediction Center. Translation: pain and suffering.

Strange when feeling current coolness and how massively different it could be in near future. Modelling hinting at relatively intense Spanish plume scenario which entertains 30C temps later next week. Solutions like this from ECMWF are not isolated this evening - currently I put it at 20% chance.

Why have SSTs in the Gulf of Mexico been warming over 2x faster than the global oceans since 2012? I cover the mystery in my post today: yaleclimateconnections.org/2026/05/some...

Coastal erosion and recession was one of the priority hazards in the Australian first National Climate Risk Assessment. These types of impacts can be expected to grow more common and more severe www.abc.net.au/news/2026-05...

Unusually high pressure over the Tasman Sea driving showery weather across eastern Australia, and allowing tropical moisture to build over central parts.

Phone, internet and council-run TV services have been making way for foreign satellite technology in rural Queensland as ground infrastructure ages, forcing councils to shut down services.

Have you ever read the Sherwood, Webb et al 2020 assessment of ECS and thought "I'd love to play with the numbers if only it didn't take 1 day to sample the posterior?" Rejoice! I've implemented the model in @mc-stan.org, and it now runs in ~1 minute. You can even run it in Google colab: 1/
