www.cambridge.org
Bill Gates, Tony Blair, CFR are rethinking climate change in the Trump era: more "realistically." Can we dismiss this trend or do we need to understand what it means global climate politics? 🧵

1. Look, there are basically just two ways to run the global oil market: petro-imperialism and petro-consumerism. Historically USA has embraced both, varying over time. The attack on #Venezuela is a return to naked petro-imperialism. Thread.

The good news? Nearly all the world’s advanced economies are now *cutting* their emissions, while still growing their economies.
(It had little to do with the Paris agreement per se, though. It was due to better technology.)

The US is at war with Venezuela.
No Congressional authorization, no public debate, no clearly stated goal, no casus belli, and a gradual ramp up rather than big opening, so many haven’t noticed (or deny it). But this attack removes the ambiguity.

The West is funding both sides of the war.
Russia's "shadow fleet" generates an estimated $87 to $100 billion in revenue per year—matching, if not exceeding, the total valueof economic and military assistance provided to Ukraine since the start of the war.

really cannot be emphasized enough that bari weiss has literally never done journalism. i don’t mean that in the pejorative sense. i mean that in the “has never performed the job she was hired to do” sense
One explanation for Bari killing the story is that she did so as a public act of fealty to the administration. But another is that, as an inexperienced journalist, she doesn’t understand that a refusal to go on the record is a kind of comment in and of itself
