🌅Morning!

💉Trump & RFK Jr often host press events at which they spout damaging BS about vaccines, Tylenol, etc; why are powerful physicians, like Drs Makary & Bhattacharya, standing by their sides nodding obsequiously?

Trump says he'll make deals with oil companies to fix Venezuela's oil industry, should help with all the resources theft their planning, and threatens Venezuela with further violence.

Trump just announces the US will be running Venezuela now, until the can do a "safe, proper, and judicious" transfer of power. Announcing an occupation before you've occupied a country is a new one.

I’m thinking this morning about all the people I spoke to last year who were absolutely convinced, and tried to convince me, that Trump would be antiwar compared to Biden and Harris.

In the past week alone he has attacked Nigeria and then Venezuela and also threatened to attack Iran (again).

Kidnapping the leader of a foreign state without any declaration of war and announcing it via social media is full-on rogue state stuff. From the world’s number one superpower.

Yesterday, I read a quick note by @michaelemann.bsky.social on the problems of UNFCCC rules on consensus that keep derailing COP after COP. It led me to organise a few thoughts on whether UNFCCC reform is still possible and what other pathways are/could be available.

Is there life after COP? And is UNFCCC reform even possible?
With so many COP 30 eulogies, we need to ask if our toxic relationship with the climate change negotiations system is part of the problem.

For some context the Morbidity and Mortality Weekly report in addition to being just a good read, to quote wikipedia, "is the main vehicle for publishing public health information and recommendations that have been received by the CDC from state health departments. "
