Great piece out today in Physics Today on historical origins, contemporary relevance, & fundamental irreplaceability of the National Center for Atmospheric Research, which remains at imminent risk of dismantling for partisan political reasons.

Tien Shan glaciers are projected to lose around one-third of their 2020 ice mass before 2040, and 69-93% by 2100, depending on the climate scenario. By the late 21stC, the probability of unmet water demand in summer will increase substantially agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Electrostate China.

Is climate change responsible for increasingly frequent or severe cold events? The evidence suggests it is not. Instead, the impact of climate change is warmer winters and less severe cold events. @hausfath.bsky.social has a great post on The Climate Brink talking about this.

In our new paper in GMD @egu.eu by @seppelampe.bsky.social, we present BuRNN v1.0: an open-access, data-driven fire model. BuRNN largely outperforms current-generation process-based fire model across a range of metrics model: github.com/VUB-HYDR/BuRNN paper: gmd.copernicus.org/articles/19/...

NEW | India is forging a different #energytransition path to China 🇮🇳⚡ Where China built first on coal and gas, India is taking a shortcut — using cheap solar to meet rising demand, relying far less on fossil fuels, and electrifying transport earlier. https://loom.ly/UFDLamw

NEW | 2025 was another RECORD-breaking year for the EU’s electricity transition, as wind and solar overtook fossil fuel generation for the first time. Here’s what happened in the 🇪🇺 power sector last year, all in one thread 👇 🧵 1/9

While Australian heatwaves were some of the very first extreme events attributed to climate change, people still underestimate how much worse they got - killing more people than all other natural hazards combined. New @wwattribution.bsky.social study. www.worldweatherattribution.org/climate-chan...

NEW | Wind and solar generated more power than fossil fuels in the EU for the FIRST time ever. 🌪️ and ☀️ made up a RECORD 30% of 🇪🇺 electricity, up from 20% just five years ago. https://ember-energy.org/latest-insights/european-electricity-review-2026/

Last week, @carbonbrief.org listed the top climate papers that were the most featured in the media. Proud to have our paper in #8! The paper here: www.nature.com/articles/s41...

Denmark's December car sales data just released. Battery-electrics reached an incredible 81% in December to make up 68% for the year.

2025 global climate highlights are out: 🌡️ 2025 was 3rd warmest year on record, 1.47ºC above the preindustrial level 📈 2023-2025 is the first three year period above 1.5ºC (according to ERA5) 🌍 The last 11 years have been the warmest 11 years on record See: climate.copernicus.eu/global-clima... ⚒️🧪🌊

China's December numbers are in, and battery-electric cars made up 35% in December and 33% for the year. Plug-in hybrids made up another 21% for the year for a total "new-energy" share of 54% in 2025. robbieandrew.github.io/carsales/

The Trump Administration's announced withdraw from the IPCC is disappointing, but not surprising. US scientists will continue to play key roles in the @ipcc.bsky.social. A statement from the US Academic Alliance for the IPCC:

The USA has pulled out of the UNFCCC. www.theguardian.com/us-news/2026...

The UNFCCC underpins global climate action. It brings countries together to support climate action, reduce emissions, adapt to climate change, and track progress. The decision by the world’s largest economy and second-largest emitter to retreat from it is regrettable and unfortunate.

Here's the EU's reaction to Trump administration formally pulling the US out of the UNFCCC and IPCC. But all eyes now on how/whether China chooses to seize this geopolitical gift from the US

2025 goes down as the ~3rd-warmest year on record (based on ERA5). Like in 2024, every single day this past year was warmer than the average of even the most recent reference period (1991-2020).

Looking back to @wwattribution.bsky.social studies in 2025 showed again, in stark terms, how unfairly the consequences of human-induced climate change are distributed. The world does not have to be like this, we have a lot of agency to make it better. www.worldweatherattribution.org/unequal-evid...

Forget “Follow your passion.” At the School for Moral Ambition, we say: Follow the Gandalf 🧙 Gandalf didn’t ask Frodo about his passions. He said: “Here’s a world-sized problem. You’re the one to fix it.” So… which big, solvable, overlooked problem could you be the unlikely hero for?

Awesome turnout in support of @ncar-ucar.bsky.social at #AGU25. Take a look at how many people use our products!

Friends at NCAR, we're with you. @ncar-ucar.bsky.social is a trailblazer in community modelling driven not by idealogy, but by open science. We share all our code, thoughts, ideas. These can't be shut down. We'll fight and find every mechanism to support the ongoing CESM community.

NCAR’s Mesa Lab is literally a science castle dedicated to understanding our planet in an open and collaborative way, and leading the world in that effort. We cannot let this happen.

Here's our reporting on the proposed dismantling of the jewel of US atmospheric science, @ncar-ucar.bsky.social. The plan is to break NCAR apart and disburse some parts to other locations (like the research aircraft fleet) and eliminate others. www.nature.com/articles/d41... 🧪 #AGU25 #climate

I know many of you who follow me don't work in climate science, but this is the biggest story in climate right now. Breaking up NCAR makes us all less safe and is another act of self-harm that will take decades to recover from.

I came to the US over 10 years ago for a postdoc at NCAR. It changed my life and supercharged my ability to do science. NCAR's unique community nature makes it a global node in atmospheric and climate research. It's really not possible to overstate its value for science and society.

NCAR is a unique & valuable asset - far more than a climate model, or observations, or technology, or training ground, or gathering space. It covers weather, space weather, data, climate, paleo-climate, and everything in-between. It's building is an icon, but it's iconic status goes far beyond that.

Uhhhh, yikes ☹️ www.nsf.gov/news/intent-...

Threatening to dismantle NCAR, our premier weather and climate research institute (apparently) because Colorado refuses to pardon someone accused of tampering with voting machines is a sad example of our current kakistocracy in action… www.nytimes.com/2025...

"Science Under Siege -- the NCAR Development" | My new commentary: michaelmann.net/science-unde... #ScienceUnderSiege

It's like on the eve of WWII we decided to stop funding R&D into weapons systems to develop advanced aircraft, ships, and tanks. Climate change is going to kick our butts if we lose NCAR (and NOAA) at a time when climate change is increasing extreme weather events capable of crashing the economy.

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.

Unbelievable. This would be a terrible blow to American science, writ large. It would decimate not only climate research, but also the kind of weather, wildfire, and disaster research that has underpinned half a century of progress in prediction, early warning, and increased resilience.

In an internal email to NSF NCAR employees, UCAR President Antonio (Tony) Busalacchi told staff: “This story is the first we have heard of any plan to target NSF NCAR, and we have already reached out to NSF to get more information.” UCAR released a media statement regarding the USA Today report:

The beautiful idea of NCAR, to improve understanding of our planet through a cooperative, shared and open intellectual team effort, is literally what has got me out of bed every morning for nearly two decades. This cannot, CANNOT be allowed to happen. eu.usatoday.com/story/news/p...

Most of the scientists at the nonprofit that I cofounded, including my two cofounders, came from NCAR. It’s hard to overstate the importance of this place for climate science.

"In regions dominated by small and rapidly responding glaciers, such as [...] the European Alps, over 50% of the glaciers are projected to disappear within the next two decades." New @natclimate.nature.com study by @landervt.bsky.social @harryzeko.bsky.social @hydr-vub.bsky.social

Research involving Vrije Universiteit Brussel reveals peak glacier extinction will hit mid-century. Up to 4,000 glaciers could vanish annually. That equals the entire European Alps population. Limiting warming to +1.5°C halves this loss. #ClimateChange #Glaciers 🔗 doi.org/10.1038/s415...

As we move into the final days of the year, 2025 has just overtaken 2022 as warmest year-to-date for Central England. Given the forecast, it looks likely that 2025 will end up being the warmest calendar year for this region since records began in 1659. The top 3 warmest will be 2022, 2023 & 2025.

It appears that the U.S. Environmental Protection Agency (EPA) has, within the past week, scrubbed a large amount of climate change content from its official website, as well as *removed human-caused warming* from the discussion on its "causes of climate change" page.

In our new study led by @amaurylaridon.bsky.social in #ORE, we present a nonlinear two-forcing emulator for the #AMOC. By accounting for Greenland Ice Sheet melt, it captures 3 additional collapse trajectories for scenarios SSP3-7.0 to SSP5-8.5. open-research-europe.ec.europa.eu/articles/5-87

Today, DOE renamed the National Renewable Energy Laboratory (NREL), one of the crown jewels of U.S. science and engineering for renewable energy, the National Laboratory of the Rockies (NLR). We should be reinvesting in our world-leading national labs not renaming them. www.nrel.gov/news/detail/...
