That almost feels like beating a dead horse at this point. Everyone in the know knows they knew. It’s just that there’s nobody powerful and interested enough to hold them to account.

This is the best summary I could come up with:

A coalition of oil and car manufacturing interests provided $13,814 (about $158,000 in today’s money) in December 1954 to fund Keeling’s earliest work in measuring CO2 levels across the western US, the documents reveal.

This ‘Keeling curve’ has tracked the steady increase of the atmospheric carbon that drives the climate crisis and has been hailed as one of the most important scientific works of modern times.

The fossil fuel interests backed a group, known as the Air Pollution Foundation, that issued funding to Keeling to measure CO2 alongside a related effort to research the smog that regularly blighted Los Angeles at the time.

The findings of this work would lead the US scientist to further experiments upon the Mauna Loa volcano in Hawaii that were to provide a continual status report of the world’s dangerously-rising carbon dioxide composition.

This essential tracking of the primary heat-trapping gas that has pushed global temperatures to higher than ever previously experienced in human civilization was born, in part, due to the backing of the Air Pollution Foundation.

Muffett said the documents add further impetus to efforts in various jurisdictions to hold oil and gas firms legally liable for the damages caused by the climate crisis.

No shit - we’ve had smoking guns for years. Add it to the pile or better yet, hold it and growl while we ask politely for change.
