It’s truly astonishing to see how comprehensively the US government is tearing down every part of the system that has made it up until now a world-leading power in science, research, and technological development. The entire world will suffer from this wanton destruction.

The American government is turning its back on the things that made us a global leader in science, engineering, and technology. Independent science — vetted by rigorous peer review, not political hacks — is crucial. This undermines our future. www.scientificamerican.com/article/whit...

This man looks like if Gollum got divorced

I’m so used to thinking of politicians as motivated by greed that I forgot about malice. Nobody’s making money off this, it’s pure destruction

This is bad. Bad for researchers. Bad for science. Bad for universities. Bad for professional associations. For example: 1. Every award would be vetted by political appointees, who could overrule peer reviewers and deny the award if it doesn't advance the president's priorities. 1/🧵

MAGHGA

Every single policy reads like it was written by a greenhouse gas

“RCP8.5 is dead but we still might reach RCP8.5 temperatures by 2150”

oh no why is RCP8.5 trending

The RCP8.5 story just seems like good scientific process: 1. we explored a wide scenario space when future warming (emissions & climate sensitivity) was uncertain 2. we focused on high-end cases because damages are nonlinear/tail risks 3. we updated to a narrower scenario space as more data come in

In the year 536 AD a massive volcanic eruption caused major climate change, forcing rats to cluster in human environments and leading to the first recorded epidemic of bubonic plague

*taps the sign*

The article misses a key point which is that, now that the identity of these designer particles is public, it's clear they don't make much sense as an SAI material.

The average household has paid over $1500 to wreck the climate and our health, isolate ourselves from the international community, and cede future leadership to China

In Human Nature I wrote about getting through the pandemic with David Attenborough

We're so excited to announce that the Drawdown Explorer just crossed the 100+ solutions mark -- and we're just getting started! Science-based climate solutions. Deep insights. Data, charts, maps, code. All free, forever.

GA Tech students and staff are incredibly impressive, Atlanta's a lucky city

Thank you for this! One of my favorite things about the ozone layer is that it's also a climate win! There are estimates Earth would be 1.1 °C warmer if we hadn't banned CFCs, which also happen to be powerful greenhouse gases. (I know you know this, just sharing for the commenters in the wings!)

In addition to the big environmental wins listed here, it's worth celebrating the smaller, local victories that often go unheralded but make those places cleaner and healthier for everyone who lives there. For example:

This answer is designed to kowtow to Trump and his devastating proposed cuts to NASA. It's baloney. NASA barely has enough money to do anything, and the cuts would wipe out entire missions. He should say it's a tiny slice of the fed budget, has a huge ROI, and funding should actually be increased.

I'd like to add the US Endangered Species Act, signed by Nixon in 1973, the first law ever to acknowledge the incredible diversity of plants and animals that share our planetary home and our obligation to protect them.

First they came for evolution Then they came for climate science Then they came for epidemiology Then they came for, like, really really basic math

In honor of Earth Day: a thread of environmental wins

And our ace podcast team (welcome back @feltman.bsky.social!) spoke to @drkatemarvel.bsky.social, @billmckibben.bsky.social, and chemist Susan Solomon about past environmental wins:

'The NSF has only committed $500 million of the $8 billion it was appropriated for the fiscal year, which began on Oct. 1. The NSF will lose the billions of remaining funding if it does not spend it by Sept. 30.' thehill.com/homenews/adm...

Dear Friends, Please send this to your networks. Project Drawdown is offering full-time, paid (with benefits) fellowships to scientists and engineers working on climate solutions in the public interest. Deadline is April 17. drawdown.org/careers/clim...

Now would be a great time to reconsider that 46% cut to NASA’s science budget for FY2027.

As a fire scientist, I am devastated for my many good friends and colleagues who will be affected by the mass closure of so many research stations and offices. Many will leave the agency. USFS has pioneered so much foundational fire science. The consequences of this will be catastrophic.

Me too! Can't wait to meet these amazing writers in LA

Every once in a blue moon I get invited to do a literary event that sounds so cool, I wish I could just sit in the audience enjoying it, rather than being on stage trying to think of what to say next. This one in LA on 4/18 w/ @chanda.blacksky.app & @drkatemarvel.bsky.social is one such event!

🍁 HEY CANADIANS I will be on your gorgeous west coast next week to 1) be jealous of your political leadership 2) talk about Heated Rivalry 3) speak at UBC. Please come say hi!

The FY 2027 NASA budget request hides its science cuts by omitting mission names instead of explicitly zeroing them out. We did the work and found 54 missions cancelled in this proposal. This is another extinction-level event for NASA science. Full list: planetary.org/save-nasa-science

In Opinion “Reasonable people can disagree on what should be done to limit the effects of climate change,” writes Kate Marvel, who last month quit her job at NASA researching the future of Earth’s climate. “But rather than debate policy, the administration has chosen to attack science itself.”

Former NASA climate scientist, now Senior Scientist at Project Drawdown, Dr. Kate Marvel, has a fantastic piece in the New York Times today. This is a must-read if you care about science, the planet, and the future. www.nytimes.com/2026/04/08/o...

the thing about a publicly funded space program is that you get to be represented by these people as opposed to, say, Jeff Bezos's second wife

The images of Earth from Artemis are amazing. But if we destroy our ability to understand (and live on) our planet, all they are is pretty pictures www.nytimes.com/2026/04/08/o...

This book may have been one of the best things I’ve read in a very long time. Absolutely recommend it to anyone who’s maybe super familiar with the physics of climate change, but wants to read something a little more human and reflective on it.

Next Wednesday, @drkatemarvel.bsky.social will be at UBC to talk about about her beautiful book Human Nature. Join us if you are in the Vancouver region, there are still a few tickets available. sustain.ubc.ca/events/ubc-r...

I’ve been there. This is true

NASA isn't why the US doesn't have universal healthcare, or a social safety net. The US doesn't have those things because politicians with the power to provide them choose specifically not to (with varying levels of support from voters). Enthusiasm for human spaceflight doesn't drive that choice.
