Facebook's new Fact-Checking policies have carved out an exemption for climate deniers

The CO2 Coalition is a non-profit climate denial organization with deep pockets supported by the Mercers, the Kochs, and other conservative fossil fuel financial interests. Despite the demonstrable unreality of its mission, the CO2 Coalition has already found favor in the White House.

In August 2019, they posted an op-ed on Facebook from the Washington Examiner that was written by a known climate denier and disguised itself as legitimate and factual reporting about climate change. As Judd Legum's Popular Information Newsletter explained:

The article claimed computer models used by climate scientists to predict warming have proved overblown, and thus shouldn’t be trusted. To prove it, Michaels compared “actual temperatures since 1979 with what the 32 families of climate models used in the latest U.N. report on climate science predicted they would be.”

The comparison was flawed. Michaels compared the earth’s present temperature with past climate models that predicted more carbon pollution than actually occurred. If we had polluted as much as the models predicted, the world would have warmed as much as the models predicted.

We know this because actual climate scientists have published research assessing the accuracy of climate models. […] Michaels’ analysis, on the other hand, didn’t go through any peer-review process, nor is Michaels climate scientist himself. What Michaels did was amateur Google sleuthing. What the scientists did was science.

Regardless, the post was shared more than 2,000 times before it was removed by Facebook's Independent Fact-checkers.

Then, according to E&E News:

A "conservative" Facebook employee quietly intervened, overturning the fact check, and the misinformation was no longer labeled as false, according to the CO2 Coalition.

If humans gave up on geoengineering after 50 years, it could be far worse than if we had done nothing at all

In Potentially dangerous consequences for biodiversity of solar geoengineering implementation and termination (published in Nature Ecology and Evolution, Sci-Hub mirror), a group of cross-institutional US climate scientists model what would happen if human embarked upon a solar geoengineering project to mitigate the greenhouse effect by aerosolizing reflective particles into the atmosphere, then gave up on the project after a mere half-century.
