How did EPA ultimately justify its decision to reverse course on greenhouse gas emissions? The agency's 3 arguments will define the inevitable court battle over this move. Here's what they are. heatmap.news/climate/epa-...

The Trump administration finally issued its justifications for repealing the endangerment finding for greenhouse gases. Now the big question: Will they hold up in court? @emilypont.bsky.social walks through the arguments: heatmap.news/climate/epa-...

lol

While I anxiously refresh various government websites because the EPA hasn't actually posted its formal repeal of the endangerment finding yet, here's what we know and don't know...

I wrote about the first 100% transparent climate risk tool. You can look up your home's wildfire risk, w/ all underlying data, methods, and code available to dl. The hope is to get this info out of black box models and invite public/scientific scrutiny and collaboration. heatmap.news/adaptation/c...

The Treasury's guidance for 45z, the Clean Fuel tax credit, indicates its moving forward with allowing biofuels producers to account for "climate smart agriculture" — which could ultimately just make the credit an even bigger subsidy for ethanol heatmap.news/politics/45z...

We are expecting the EPA to make a decision about its "endangerment finding" for greenhouse gases in the next week or so. While many expect the agency to rescind it, there's a few important questions to look out for about how the move is justified. Here's why. heatmap.news/climate/epa-...

What if our thinking about Elon Musk is all wrong? What if he isn't the next Henry Ford, but the 21st century's Jack Welch or John D. Rockefeller? techcrunch.com/2026/02/01/b...

climate reporting under the Biden admin: tracking grant announcements climate reporting under the Trump admin: tracking lawsuits

Michigan's new fossil fuel lawsuit is fascinating. The state is alleging antitrust violations, arguing that Big Oil colluded to stifle competition. I spoke to experts about the case and the challenge of proving conspiracy vs. independent responses to market pressures. heatmap.news/climate/mich...

Vineyard Wind has about 10 turbines left to complete. Now it can get back to working on them. heatmap.news/sparks/viney...

BREAKING: Construction on Vineyard Wind can proceed, according to a federal judge. That marks four losses in a row for the Trump administration against offshore wind. Read more from @emilypont.bsky.social: heatmap.news/sparks/viney...

there's a new-ish player in the world of ultra-long duration (100+hour) battery storage: Noon Energy. last week, the startup announced the successful demo of its carbon-oxygen battery, which it hopes to commercialize as soon as next year to provide behind-the-meter power to data centers

The DOE revealed today that it cancelled some $30 billion in loan guarantees for Biden-era clean energy projects and is "revising" another $53 billion worth. Those numbers include public cancellations from last year like Grain Belt, but the remainder is ???? heatmap.news/sparks/83-bi...

Vineyard Wind is sounding the alarm that Trump's stop work order is getting in the way of its efforts to replace the defective blades that caused the 2024 broken blade fiasco, paradoxically creating new hazards. Scoop w/ @jael.bsky.social heatmap.news/politics/tru...

Would still love your recommendations on this if any come to mind!

“The most popular scope 3 models assume an entirely American supply chain. That doesn’t square with reality.” Deft summary of our latest paper by @emilypont.bsky.social in @heatmap.news: heatmap.news/sustainabili... Open access paper here: www.nature.com/articles/s41...

Scientists were frustrated by a piece in the Guardian earlier this week that seemed to call into question the science on microplastics in the body. I wrote about why researchers are certain microplastics are in the human body -- and what we still don't know: www.washingtonpost.com/climate-envi...

News from me: Trump has lost yet again in court over the stop work order halting Coastal Virginia offshore wind The offshore wind sector is now 3/3 in court this week @heatmap.news #greensky #climatesky #energysky

Great story by @mariagallucci.bsky.social on how Trump forcing all Department of Interior reviews of clean energy projects to get personal approval from DOI Secretary Doug Burgum has stifled 22GW of development in the midst of an energy crisis: www.canarymedia.com/articles/cle... #energysky

NEW: A federal judge has lifted Trump’s stop-work order for New York’s Empire Wind project, allowing construction to continue and dealing yet another legal blow to the president’s war on offshore wind @jael.bsky.social reports: heatmap.news/sparks/new-y...

My sense is that when people advocate for not speaking of "climate change," they are pretty narrowly talking about not using it in certain political and policy contexts, and not implying that the words never be spoken or the issue be abandoned

Interesting to see the Guardian's @dpcarrington.bsky.social weighing in on this. My take, as someone covering microplastics heavily for the past year (and currently sitting at a 200+ person conference with many of the scientists in question): www.theguardian.com/environment/...

2025 was bleak but someday we will have fusion at sea and SMRs underground heatmap.news/climate-tech...

Day in the double-life of superstar @jael.bsky.social 🙇🏻‍♀️

it’s probably really important for anyone reading about the offshore wind stuff today to know the military already spent many years addressing these issues and those reviews are well documented, can be filed in court

Its not just energy demand putting pressure on utility bills. Many states and utilities are implementing wildfire mitigation and preparedness plans representing hundreds of millions in costs that "won’t hit utility customers for years," @robinsonmeyer.bsky.social writes. heatmap.news/energy/wildf...

⚠️ It’s official! New York has repealed the “100-foot rule” subsidy for new gas hookups, joining five other states that have ended similar subsidies. Statement from Hochul:

The House passed the SPEED Act today, which would make sweeping changes to NEPA. But a last minute tweak to safeguard Trump's meddling with previously-approved renewable energy projects pissed a lot of people off. A Senate deal won't be easy. heatmap.news/sparks/speed...

I did a lengthy interview with the CEO of Stardust, in which he walked back the solar geoengineering startup's testing and deployment plans a bit. The company also intends to release details about its proprietary particles early next year and expects to open a US office soon.

New: Key Senate Democrats told @jael.bsky.social they want a permitting deal that supports transmission and clean energy, and that the current House proposal, the SPEED Act, "does not meet that standard." heatmap.news/politics/sch...

Hello! Do you have a friend or family member (a boomer in your life, perhaps?) who was looking into #heatpumps 🔌⚡ and then wouldn't stop going on and on to you about the technology or trying to give you a physics lesson? Please DM me or respond here, I would like to talk to you!

Permitting reform is back, and there's a lot of motivation on both sides to get a deal done — Trump's war on wind and solar, interest in AI leadership, energy affordability. The debate is impenetrable as ever, so I wrote this guide to help you (and myself tbh) follow it heatmap.news/politics/per...

My colleague @emilypont.bsky.social wrote THE explainer on the big “permitting reform” bill Republicans are trying to pass this Congress She really nails what the bill would do and why some cleantech people like it while many others really don’t I highly encourage all wonks to read

permitting reform is on the table once again. with the SPEED act expected to come to a vote on the house floor in the coming weeks, @emilypont.bsky.social breaks down where the debate stands this time around

I wrote this spring about an intriguing idea: Could utilities pay people to electrify their home with new appliances, instead of just swapping out old pipes? nysfocus.com/2025/03/10/n... @emilypont.bsky.social profiled the woman who’s actually doing this, on her own, for ConEd. Wonderful piece:
