Proud to be part of the Expert Working Group on Climate Change and Health that just put together a report summarizing the evidence of health harms of climate change to date. Report is here: zenodo.org/records/1728... 🛟 #climatesky

The path between here and a just and livable future is not a smooth curve of managed transition any more (if it ever was). It's white water, surprises, confusion, advance, retreat, learning, messing up, grieving, celebrating, experimenting, truth telling, pausing in the beauty.

This Expert Working Group on Climate Change and Health in the United States comprises 114 scientists with experience researching various dimensions of the health effects of climate change. We are submitting this public comment in response to the proposed reconsideration of the Endangerment Finding and Greenhouse Gas Vehicle Standards. Our overall conclusion is that EPA is incorrect in its assessment of uncertainties in the 2009 Endangerment Finding as a reason to reconsider the rule, given that the scientific evidence since that time reduces the uncertainty regarding health harms from climate change stemming from greenhouse gas emissions. Greenhouse gas emissions, by altering the climate and disrupting earth systems, pose a clear and indisputable danger to human health and well-being.

Another expert review of the science behind the endangerment finding, this time from health professionals.

they conclude that CO2 emissions "pose a clear and indisputable danger to human health and well-being."

A Rhode Island Wind Farm Changed Their View. And Their Lives, for the Better.

The end of soot-laden windows. The arrival of broadband internet. Cheaper and more reliable electricity. Rhode Island’s first electricity co-op. The return of birdsong.

Here are the myriad benefits the first US offshore wind farm has brought to Block Island, from @catrineinhorn.bsky.social.

The recent DOE climate science report misrepresents the work of many researchers. Carbon Brief asked those cited to review the parts of the report where their work was used, and we collectively found 100+ misleading or false statements: interactive.carbonbr...

YouTube video by CBS Sunday Morning Elon Musk on DOGE and his work in and out of government

Beyond frustrating and disappointing that CBS got a rare exclusive sitdown interview with Musk and didn’t ask him a single question about his reckless and ignorant cuts to USAID and all the lives that are being lost across the world as a result of it:

These regulations might produce acute costs for producers from plant retrofits and retirements, but they provide diffuse benefits to all of society from improved air quality and lowered greenhouse gas emissions.

It’s little surprise which group’s interests matter to EPA administrator Lee Zeldin.

The political theory behind IRA was roughly as follows: We have lost control of the information landscape and can no longer win rhetorical or purely political battles; however, if we make substantive policy progress that directly touches voters' lives, they will notice and reward us.

A foundation model for the Earth system - Nature Aurora, a new large-scale foundation model trained on more than one million hours of diverse geophysical data, outperforms operational forecasts in predicting air quality, ocean wave dynamics, tropica...

Researchers at Microsoft just introduced Aurora, their new AI earth system model.

It can produce global air quality forecasts that match or beat the performance of the Copernicus Atmosphere Monitoring Service — at 100,000 times the speed.

They blame pollution but cut the EPA and clean air and water regulations. They blame poor nutrition but cut SNAP and programs to bring local produce to schools. They blame increased screen time while destroying public infrastructure that connects people. All while they take millions off healthcare.

At the same time, Slotkin spoke out against the procedural aspects of the vote. Republicans argued that the Congressional Review Act gives Congress the ability to overturn rules passed by federal agencies, but Democrats argue that bypassing the filibuster sets a dangerous precedent, with some even questioning the legality of the move. "Unfortunately, the way Senate Republicans brought this vote to the floor will have longstanding implications for how we change and make laws in the U.S. Senate. That is why I voted at least 11 times against the Republican attempts to change the Senate rules and bring this provision to the floor," Slotkin said. "House Republicans last night gutted those incentives for EV advancement. And let's make no bones about it, if this becomes law, China is poised to dominate that global marketplace for the foreseeable future at our expense."

Such deft political maneuvering here by Sen. Slotkin, who opposed the process Republicans used to revoke California's vehicle emissions waivers and then ... joined Republicans in revoking California's vehicle emissions waivers. www.cbsnews.com/detroit/news...

Whenever Trump announces some new authoritarian policy, like the ban on Harvard international students, the first two questions should always be:

1) Can he do that?
2) If he can't, will he get away with it?

More often that not, the answers are no. And I think this case will fit the pattern.

Harvard Sues Trump Administration Over Move to Bar International Students

Breaking News: Harvard University sued the Trump administration less than a day after the government said it would block international students from attending.

Congress moves to loosen toxic air pollution rules The House and Senate both voted to loosen regulations on air pollutants like dioxin and mercury, which are associated with higher cancer risk.

"The decision represents the first time since the creation of the [Clean Air Act] that Congress has rolled back its environmental protections."

This means some facilities will no longer need to use maximum achievable emission controls for hazardous air pollutants such as mercury, lead, and benzene.

Cover of new REPEAT Project report, "A Fork In The Road: Impacts of Federal Policy Repeal On The U.S. Energy Transition."

Summary Full repeal of current federal energy and climate policies would: • Increase U.S. greenhouse gas emissions by roughly 0.5 billion metric tons per year in 2030 and more than 1 billion metric tons per year in 2035. • Raise U.S. household and business energy expenditures by $25 billion annually in 2030 and over $50 billion in 2035. • Increase average U.S. household energy costs by roughly $100 to $160 per household per year in 2030 and roughly $270 to $415 per household per year in 2035. • Reduces cumulative capital investment in U.S. electricity and clean fuels production by $1 trillion from 2025-2035. • Imperil a total of $522 billion in announced but pending investments in U.S. clean energy supply and manufacturing. • Reduce annual sales of electric vehicles by roughly 40% in 2030 and end America’s battery manufacturing boom. • Substantially slow electricity capacity additions, raising national average retail electricity rates and monthly household electricity bills by about 9% in 2030 — and as much as 17% in some states (including TX, OK and PA). • Kill off the nascent clean hydrogen, CO2 management, and nuclear power sectors.

Most Americans use federal science information on a weekly basis, a new poll finds Most Americans frequently use federal science information. But few are concerned that cuts to federal science spending could affect their access to such information, a new poll finds.

The scientific community is at a pivotal moment right now. And we are seeing things start to shift. Now is the time for scientists and scientific institutions to step up. No one is coming to save us. 🧵

Senate overturns EPA rule on seven highly toxic air pollutants If also passed by the House as expected, the action will be the first time Congress has weakened protections under the Clean Air Act.

Because they felt that air pollution isn't killing enough Americans, the Senate voted to overturn an EPA rule that limits toxic air pollutants emitted by industrial facilities, marking the first time Congress has weakened protections under the Clean Air Act.

Citing N.I.H. Cuts, a Top Science Journal Stops Accepting Submissions (Gift Article) With federal support, Environmental Health Perspectives has long published peer-reviewed studies without fees to readers or scientists.

During graduate school, studies published in Environmental Health Perspectives regularly offered models of robust and compelling science that helped guide my work.

Some of the best research on air quality and public health graces EHP's pages. The journal's discontinuation would be a real shame.

AGU has filed a new lawsuit to prevent the Administration’s dismantling of U.S. scientific agencies.

We’re proud to take this stand with our plaintiffs’ coalition for our federal workforce.
