I can't stress enough how close U.S. science is to the cliff. "Numbers released in May by the National Science Foundation (NSF) indicate that if Congress approves the cuts to the agency proposed by the White House, the number of early-career researchers it supports could fall by 78%" (@science.org)

I categorically disagree with claims that CO₂ removal (CDR) is a scam. The field is full of smart people dedicated to figuring out what, if anything, works, because we’ll need CDR in the future for legacy and residual emissions. Funding via market mechanisms isn’t ideal, but doesn’t make it a scam.

🌲 Did you know over 13 million metric tons of biogenic CO₂ are mineralized into carbonates each year in U.S. pulp mills — but then released back into the atmosphere? Our new study shows how we can capture that CO₂ instead — at low cost. 🧵 1/5

The UK/EU agreement today includes linking the UK and EU's carbon pricing systems (known as Emissions Trading Systems). A couple of observations... 1) If it wasn't already clear, this makes it obvious that the UK's commitment to net zero and its access to European markets are closely linked

In case anyone needs to reference the DOE's liftoff reports, which no longer appear on the official website: yardsale.energy/liftoff-repo... 🔌💡

Lets be a little careful here; while it seems to be the case that there have been real performance challenges, it is also not uncommon that other clean energy technologies (EVs, solar panels, etc.) take a year or two of operation to pay off their embodied emissions:

Two days remain to comment on the US FWS and NMFS rule change that undermines the Endangered Species Act (ESA). This proposal rescinds the definition of “harm,” limiting protections to actions that directly injure or kill listed species, leaving their habitats vulnerable. Please submit comments! 🧪

Great to see today's announcement of a JP Morgan debt facility, backed by The Schmidt Family Foundation, for Mati Carbon to advance the deployment of enhanced weathering with smallholder farmers in the Global South. High-leverage + super-catalytic philanthropy 👏👏👏 www.prnewswire.com/news-release...

Some thoughts from me on the current US administration's disastrous plans for science and technology funding.. It is time for everyone to speak up and ask for the investments that we need! galenmckinley.github.io/commentary/C...

Honestly, could this is why the big oil and their political enablers are behaving so badly? Hold on tight people!

Let's be real: if Republicans pass the House budget bill as is, it will murder the US nuclear industry, ruin our chances of winning the AI race (by constraining power supply), concede the global auto sector to China, and vaporize about half a trillion dollars of US manufacturing investment...

The 7 billion tonne gap! Climate science & national emissions reporting use different definitions & methods to estimate anthropogenic land-based carbon removals. This is no small issue, but what can we do about it? www.nature.com/articles/s41... (sorry, shareable open link not yet published). 1/

What does the House Energy & Commerce Committee's draft reconciliation bill mean for IRA funding programs? We @sabincenter.bsky.social estimate that $10 billion in IRA funding (and perhaps much more) is at risk of rescission. Our latest blog has more info: blogs.law.columbia.edu/climatechang...
