In 2024 and 2025, a spring drought hit Northern Germany, an extreme rainfall event led to severe flooding in Southern Germany, and a heatwave affected all of Germany. We find that people misestimate how frequently such events occur in the current climate with around 1.3°C of global warming.

As you are suffering through this #heatwave, remember: One billionaire going on a 11-min-flight into space emits more greenhouse gases during those 11 min than any person from the 1 billion people with the lowest emissions will emit during their entire life wir2022.wid.world/chapter-6/

The hottest summer days are warming faster than monthly average temperatures. Only looking at changes in average temperatures can hide the most extreme and dangerous changes we are experiencing. Good threat by @hausfath.bsky.social on the new attribution study by @wwattribution.bsky.social 👇

Heat waves are driven by weather patterns but occur on the backdrop of a rapidly warming world. Without climate change the current European heat wave would have been ~3.2 °C (5.8 °F) cooler. Heat impacts are non-linear, so this higher severity can lead to much greater suffering

The London Ambulance Service responded to the highest number of life-threatening emergencies in its history yesterday. The Chief Executive said this was "driven by the extreme heat across London".

The London Ambulance Service responded to the highest number of life-threatening emergencies in its history on Wednesday. Temperatures soared to 36.1C in parts of the UK on Wednesday, and that record for June has been broken again today. Ambulance crews responded to 642 calls relating to category 1 incidents - those that include the most serious, life-threatening injuries and illnesses such as cardiac arrests and patients who are not breathing. Chief Executive Jason Killens KAM said this was "driven by the extreme heat across London".

Leaders around the world are banking on tech advances to solve climate change. One leading idea involves capturing carbon pollution from the air and then burying it underground forever. It sounds practical. Here’s why there's no conceivable way it can work: (THREAD)

How can scientists, practitioners and communities collaborate to create actionable climate information for local climate change adaptation? Slowly heading toward the third and last Adaptalab of IMPETUS 4 CHANGE (I4C), where we will create policy briefs capturing our I4C experiences.

Heading to #SRAEurope2026 now Please reach out if you want to chat about climate risks, risk perceptions and the use of climate information in adaptation decision-making. Also, if you are already around and want to explore the city, feel free to reach out too.

📈Why is there is upward trend in billion-dollar disasters? 1. There is a growing number of people, homes, and businesses exposed to these hazards. 2. Climate change is causing an increase in frequency and intensity of certain types of extreme weather. That's a bad combo.

NCAR is quite literally our global mothership. Everyone who works in climate and weather has passed through its doors and benefited from its incredible resources. Dismantling NCAR is like taking a sledgehammer to the keystone holding up our scientific understanding of the planet. Unbelievable.

Trump moves to dismantle major US climate research center in Colorado

The Trump administration is breaking up the National Center for Atmospheric Research, taking aim at one of the world's leading climate research labs.

What issues matter most to #Voters? 😬 @gefjonoff.bsky.social & @fedetrastulli.bsky.social study 6 European countries to find that different groups care about different issues--and that what people care about isn’t the same as what they think about those issues. 🧭🗳️

What is the most profitable industry in the world, this side of the law? Not oil, not IT, not pharma. It's *scientific publishing*. We call this the Drain of Scientific Publishing. Paper: arxiv.org/abs/2511.04820 Background: doi.org/10.1162/qss_... Thread @markhanson.fediscience.org.ap.brid.gy 👇

We wrote the Strain on scientific publishing to highlight the problems of time & trust. With a fantastic group of co-authors, we present The Drain of Scientific Publishing: a 🧵 1/n Drain: arxiv.org/abs/2511.04820 Strain: direct.mit.edu/qss/article/... Oligopoly: direct.mit.edu/qss/article/...

A table showing profit margins of major publishers. A snippet of text related to this table is below. 1. The four-fold drain 1.1 Money Currently, academic publishing is dominated by profit-oriented, multinational companies for whom scientific knowledge is a commodity to be sold back to the academic community who created it. The dominant four are Elsevier, Springer Nature, Wiley and Taylor & Francis, which collectively generated over US$7.1 billion in revenue from journal publishing in 2024 alone, and over US$12 billion in profits between 2019 and 2024 (Table 1A). Their profit margins have always been over 30% in the last five years, and for the largest publisher (Elsevier) always over 37%. Against many comparators, across many sectors, scientific publishing is one of the most consistently profitable industries (Table S1). These financial arrangements make a substantial difference to science budgets. In 2024, 46% of Elsevier revenues and 53% of Taylor & Francis revenues were generated in North America, meaning that North American researchers were charged over US$2.27 billion by just two for-profit publishers. The Canadian research councils and the US National Science Foundation were allocated US$9.3 billion in that year.

To my followers: What do you think about messages like this? Are they understandable, useful and credible? Really curious to hear your thoughts :)

#Melissa rocketed to Category 4 strength overnight — gaining 70 mph in just 24 hours over unusually warm Caribbean waters made 600–700x more likely by climate change. It’s the 4th storm this season to undergo Extreme Rapid Intensification. (#Erin, #Gabrielle, #Humberto)

Hamburg just said YES in the climate referendum! ♥️ Thanks to everyone who fought for it. This vote matters for Hamburg – and sends a strong signal far beyond. The climate issue is alive: we can set the agenda and win! Another lesson: climate action must go hand in hand with social justice.
