An important discussion about the use of silicates vs. carbonates for enhanced rock weathering to remove atmospheric carbon dioxide. https://podcasts.apple.com/us/podcast/reversing-climate-change/id1321759767?i=1000745262429

A major success for science thanks to @apsphysics.bsky.social staff and 5,300 volunteers. www.nytimes.com/2026/01/10/s...

It is hard to overstate how critical @ncar-ucar.bsky.social is to climate science in the US and around the world. It's the beating heart of our field. Generations of scientists have trained there, and almost everyone I know relies on deep collaborations with NCAR scientists. It's end is unthinkable.

Preening politicians made things worse in education by overtesting students and they're doing the same with firebreaks and other failed strategies: www.latimes.com/environment/...

Starting field trials of enhanced rock weathering (ERW) to remove atmospheric carbon dioxide (CDR).

Joy.

It's official: -2025 is now a more threatening year for the survival of the republic than 1968. -John Roberts will now go down in history as a worse chief justice than Roger "Dred Scott" Taney. www.nytimes.com/2025/10/11/u...

Video of my talk about "Atmospheric Carbon Dioxide Removal: A Physical Science Perspective" is up: youtu.be/OMN1B76MPpk?...

Indeed. Earlier this summer, the White House did this to me, as a scientific expert source in media, and issued a formal statement regarding my personal campaign contribution history in an attempt to discredit my commentary on wildfire, climate, and federal policy. Yet more alarm bells ringing...

Climate science is the most significant scientific collaboration in history, and its lessons are a massive human achievement. “How We Came To Know Earth,” our new series, is a guide to the modern understanding of fundamental climate science. www.quantamagazine.org/series/clima...

Hiked 450 miles of the #pacificcresttrail thru the state of Washington last month. This tread will have some photos in chronological order. First up: Bridge of the Gods across the Columbia River.

The Wise Use Agenda itself is an enormous rabbit hole (which you too can fall into here www.documentcloud.org/documents/13...). On its face, it doesn't seem too bad... "enough food, clothing, shelter and jobs for all mankind to live in humane conditions" ok sure

The video recording of my public lecture in Aspen is now up: "Can Physics Stop Climate Change?" https://www.youtube.com/watch?v=8zkDelyDcUo

Happy to share our new paper: we show that human-caused climate change is raising the odds of extreme climate-driven fire years across forested regions of the globe @climate-guy.bsky.social @pyrogeog.bsky.social rdcu.be/evJkX #ClimateChange #Wildfires

This is a note I sent the Project Drawdown team today. Thought it might be helpful to others working on the climate front…

As a fire scientist, my first reaction to these maps is that these places are gonna burn. Any time you open up public lands to private or communal ownership that does not center fire stewardship of the land, ignitions and fire events increase dramatically. www.wilderness.org/articles/med...

It's like evil Gifford Pinchot drew a map. That's a lot of national forest land in the Lower 48 and a massive amount of BLM land in Alaska. Some of the best public lands we have will be available for purchase, but not by people like you or me. Thanks to @wilderness.org for pulling this together.

Meanwhile here in San Marcos, huge turnout for #NoKings

Huge turnout in Santa Barbara with lots of young people.

🧪Now we have to see what the Congressional Appropriations Committees do. This is definitely the time for people to write to their lawmakers. American Physical Society link that I've posted before is below. You do not need to be a member of APS. www.aps.org/initiatives/...

We cleared Whitethorn Ceanothus from the #bigfoottrail in the northern Yolla Bolly wilderness. The California Conservation Corp joined us on Friday. They may have wondered if a judge had sentenced us to community service in the hot sun!

The president's budget proposal cuts billions in funding from the DOE Office of Science, NIST, NASA, and the NSF — but there’s still time to change it. Tell your lawmakers why they should stand up for science using our letter-writing toolkit, targeted to your state: go.aps.org/3RP9EWF

The move comes as the US's nascent offshore wind industry is facing uncertainty, with all future leases placed on hold by an executive order issued on the day of Trump's inauguration.

“Everybody in math and physics uses it.” Nearly 35 years ago, Paul Ginsparg created arXiv, a digital repository for sharing research. It changed science for good. Three decades in, Ginsparg reflects on its legacy—and its future.

College cove.

The Fix Our Forest Act is currently in the Senate Committee of Ag, Nutrition, and Forestry. This bill has calls to circumvent NEPA and undermine the Endangered Species Act. This will NOT “fix” our forests—it will only make it easier to cut trees without the proper review on environmental impacts.
