Grateful to be part of this work and to collaborate with such a thoughtful team. The findings highlight substantial Tribal adaptation underway, yet climate services still have a long way to go to meet their needs. Deep thanks to @kimberlyazzie.bsky.social for her leadership.
🚨Publication alert!
We conducted a national survey to understand the state of climate services for Tribes and how well they support Tribal adaptation efforts.
In short: Tribes are deeply engaged in adaptation, yet relatively poorly served by available climate services.

As far as I can tell, RFK Jr.'s latest antivax stunt runs counter to the WMA Declaration of Helsinki. Withholding HepB vaccination clearly does not meet any definition of clinical equipoise. Doing it anyway, overseas, is straight up colonialist medicine.
