Assistant Professor of Geography at the University of Nebraska at Omaha. I research climate and human health interactions with a focus on extreme heat. Penn State Forever.

2025: Pretty good (personally, at least) until the whole breaking my ankle thing. As I watch the London NYE festivities since I won't be awake at midnight here, I'm going to say farewell to social media until 2027 to try and become a better, deeper version of myself. Be good and do good, everyone.

Global CO2 from fossil fuels is projected to hit a record 38.1B metric tons in 2025, up 1.1%. Increases in the U.S., India and China, plus a 6.8% jump in aviation, outpace clean energy gains. Researchers warn that staying below 1.5°C is no longer plausible.

Record fossil fuel emissions in 2025 despite renewables buildout, report says

Global carbon dioxide emissions from fossil fuel combustion are projected to reach a record 38.1 billion metric tons in 2025, an increase of 1.1% from 2024, according to the 2025 Global Carbon…

Bob and I were among the hundreds of researchers that were supposed to conduct the 6th U.S. National Climate Assessment. Now it looks like they're gonna produce it with a few people and Grok? Communities need rigorous and accurate information about climate change. This will put communities at risk.

Maue did not respond to requests for comment from E&E News. But he wrote on X that he was enlisting artificial intelligence to help with the latest National Climate Assessment. He cited the Gemini 3 Pro program as well as Grok, an Al chatbot developed by xAl, the artificial intelligence company led by tech tycoon Elon Musk. https://www.eenews.net/articles/its-the-gold-standard-of-us-climate-research-contrarians-could-write-the-next-one/

I look forward to the legally required, transparent peer review process required by the US Global Change Research Act and the Information Quality Act. I always thought they would try to do a NCA with Judith Curry, five old men and a LLM.

Before the 1990s, plane crashes caused by microbursts used to kill planeloads of people fairly regularly. Dr. Ted Fujita and NCAR scientists figured out how to detect microbursts and warn pilots about them. Since then? Zero airliner crashes from microbursts.

Exclusive: The Trump administration is moving to dismantle the National Center for Atmospheric Research in Colorado, according to a senior White House official, taking aim at one of the world's leading climate research labs.

Air and road travel are safer, hurricanes, thunderstorms, and wildfires are better predicted, students, early career scientists, and teachers are trained, and the public learns more about STEM because of NCAR. We’ve spent decades preaching STEM and we’re destroying it all in less than a year.

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.

This entire grift relies on convincing people that they don't know how to do the things they have always known how to do, and ironically, if it works, we will, in a very short amount of time, forget how to do all the things we have always known how to do.

Jimmy Fallon: "And do you use ChatGPT when raising your baby?" Sam Altman: "I cannot imagine figuring out how to raise a newborn without ChatGPT."

Additionally, it appears that all of EPA's previously extensive "indicators of climate change" pages have been scrubbed entirely. The pages no longer exist; there are numerous dead links on the current/live EPA site, and no indication they have been moved to a new URL.

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.

bums me out kinda bad that all the cool life-saving shit ai was always supposed to do, working through immense amounts of data incredibly fast to tailored ends, has to have a disclaimer slapped on it like "no not the plagiarism machine that urges you to commit suicide" now

Meteorologists are surprised that the weather model that did the best job forecasting hurricanes this year was a new one, introduced by Google. AI may be the beginning of a new era of forecasting. n.pr/49MFa1M

Beer talk: This year's BCBS Chocolate Praline Stout might be the best boozy dessert stout I've ever had. It's what watching the snow fall while watching It's a Wonderful Life on Christmas Eve night tastes like.

I used to handle interlibrary loans for a public library. ILL is a magnificent expression of the idea that readers deserve books, and books deserve readers. It’s libraries everywhere pooling their resources for the benefit of everyone. Killing IMLS could have killed ILL. This is great news. 📚
