Merchants of Doubt (2014) with Naomi Oreskes, Jamy Ian Swiss, Frederick Singer Movie

1/ Given CDC evisceration, attacks on climate science, NASA... here's a short tale of worrisome prescience from 2014.
I attended an early showing in San Francisco of the fine film "Merchants of Doubt". It has book's foci of climate denial/tobacco, but adds more.

Louisiana Surgeon General Ralph Abraham has just been named as the principal deputy director at the CDC.
Abraham’s accomplishments include banning the health department from promoting vaccines and overseeing the concomitant explosion of whooping cough in the state, which has killed two babies.

Plausible that Trump’s policy of mass deportations will not just end a “temporary shift” among Hispanic voters but also lead to a more durable U-turn. In California, the 1994 “anti-immigrant ballot measure Prop 187 marked the death knell of the Republican Party.” calmatters.org/commentary/2...

In a 2024 paper criticizing the 'billion-dollar-disasters' database, Roger Pielke Jr. published analysis that is best described as a Russian-doll of errors.
