This Bloomberg piece highlights China's extraordinary development of energy capacity, primarily through renewable energy sources. "China’s energy-building rush has no match. In the past four years, it has added more power generation than the entire US system." Link in comment 👇

For those who were off the grid for snowmageddon: how and why the US withdrawal from global climate bodies is so important...

These are not “tariffs” - they are unilateral economic sanctions and a violation of Int’l trade law - media and pundits need to stop normalizing this unlawful economic coercion with the term “tariff.”

My thoughts on why the US withdrawal from int'l climate institutions, particularly the UNFCCC and the IPCC, is so significant, and poses a real threat to the global effort to address the climate change crisis. Link in the comment 👇

This is a useful compilation, by a post-doc at Basque University, of formal national responses to the US & Israeli strikes against Iran last year: addi.ehu.es/bitstream/ha...

Very interesting. (And disquieting to hear of big bets on Venezuela invasion hours before the intervention!). Link below 👇

Judge Young's final "annotated order" in AAUP v. Rubio, just issued. A huge First Amendment victory. Very proud of my colleagues @ramyakrishnan.bsky.social @alexabdo.bsky.social @georgewang.bsky.social & grateful to our clients @aaup.org @mesa1966.bsky.social. knightcolumbia.org/documents/k4...

The @wsj.com is today reporting that the Trump Administration is actively seeking regime change in Cuba, based on info from high-level sources. Gift link in comments 👇

Mark Carney's Davos speech, and particularly what he has to say about the current rupture of the international legal order, and future of international relations, is very much worth listening to: www.youtube.com/live/Pg4rNz8...

My interview last week with Noura Doukhi of Lebanon's L'Orient-Le Jour, on the lawfulness of any humanitarian intervention to protect protesters in Iran (spoiler: unless authorized by the UN Security Council, any military intervention would be unlawful). www.lorientlejour.com/article/1491...

This piece from last month, by @mikeschmitt.bsky.social and Marko Milanovic, remains just as important today. Where is Congress? Link 👇

No tariff decision today...

SCOTUSBLOG for live-blogging of the decisions coming down this morning....

Bloomberg Green examines the methane emission implications of US ramping up extraction of Venezuelans fossil fuels. Link in reply 👇

The US announced today that it is withdrawing from 66 more international organizations, agencies, and institutions, including the ILC! So disappointing and disheartening - this makes Int’l cooperation and coordination on shared challenges much more difficult. www.whitehouse.gov/presidential...

Today's op-ed by @oonahathaway.bsky.social in the @nytimes.com nails why it is so important for all states to defend the international legal order, and call out the intervention in Venezuela as unlawful. The whole piece is worth your time - gift link in the comment 👇

Very good basic analysis here 👌

For those who missed this over the weekend…that much more relevant after the events of this weekend! Link in first reply.

I have a thread over at the hellsite tracking state reactions to the Venezuelan regime change op btw. Sorry can’t do it here cuz there’s not enough ministries and I don’t have a List for that x.com/alonso_gd/st...

Here is my preliminary analysis of the US intervention in Venezuela, and brief explanation of the violations of international law so far. craigxmartin.substack.com/p/the-us-int...

This is an extraordinary response from a leader of a political party in Canada - celebrating and endorsing a clearly unlawful act of aggression.

New episode of JIB/JAB - a discussion with @monicahakimi.bsky.social of Columbia Law about how to better understand and respond to the current crisis in international law. Fascinating and important conversation! Link in reply 👇

For those who missed it (I did), this episode of Bloomber's Zero podcast is an interesting discussion with Canada's former Minister of the Environment on the new government's retreat on climate change policy: podcasts.apple.com/us/podcast/i...

For those who missed this over New Years ;-)

My thoughts on the importance of the conflict in Sudan-not only because it's the worst humanitarian crisis, if largely ignored in public discourse-but because the UN Security Council's failure to resolve it reveals further weakening of the UN collective security system. Link below 👇

The @nytimes.com confirmed earlier reports that the CIA conducted a drone strike on dock facility in Venezuela last week (link 👇), with large explosion but no casualties reported. 1/2...

More indications that Japan is considering departing from the long-established non-nuclear principles - which could lead to a nuclear arms race in Asia. www.japantimes.co.jp/news/2025/12...

NY Times reports that this tanker was not on any OFAC sanctions list, and there was no seizure warrant authorizing it under domestic law - even more lawless than the first seizure. www.nytimes.com/2025/12/20/u...

Great post by @stevevladeck.bsky.social on the anniversary of Korematsu, explaining why the legal justifications and rationalizations for unlawful action is often more damaging to the rule of law than the action itself. Necessity, Legality, and the Rule of Law open.substack.com/pub/stevevla...

Perplexity just released an internal report on how the company actually uses its own platform internally - it is being touted as a useful guide for very practical application: www.perplexity.ai/hub/blog/ai-...

Canada’s anti-greenwashing rules protect our health, but they’re under threat. Send a message to Ottawa: don’t give fossil fuel companies the license to lie to us. Choose truth, health and transparency instead. cape.ca/action/prote...

My thoughts on how the recently announced Canada-Alberta agreement on expanding Alberta’s oil and gas production violates Canada’s international law obligations regarding climate change - and why that matters. open.substack.com/pub/craigxma...

Interesting analysis in The NY Times of discussions between DoD and the State Dept about how to deal with boat strike survivors. www.nytimes.com/2025/12/09/u...

"Legally shaky"?! This headline in the @theguardian.com is irresponsible- there's overwhelming consensus among legal experts that the strikes are unlawful. The article itself states "The rationale has been widely rejected by most legal experts..." Media have to do better! bit.ly/3YfFU8k

Not surprising - it is impossible to square the government's pipeline deal with Alberta with Canada's climate change goals and obligations. www.thestar.com/politics/fed...

Exactly right.

This piece by @mikeschmitt.bsky.social, @rgoodlaw.bsky.social, and @tessbridgeman.bsky.social, on @justsecurity.org, is an outstanding precise analysis of the legal issues surrounding the “second strike”. www.justsecurity.org/125948/illeg...

The MSM are focusing on the wrong issues/questions. - It doesn't matter whether he saw survivors, or whether he specifically ordered a 2nd strike. - Evidence is he gave an order to kill them all (a "no quarter" order); ... 1/2 www.bbc.com/news/article...

As I and many others pointed out over a year ago, Hegseth made very clear his intention to disregard international humanitarian law and human rights law. Congress should not now be surprised - but it should do something about it!
