A Biden administration report required by Congress outlines research options for a last-ditch effort to slow the heating of the planet. But the White House says its not changing its climate strategy.
The White House offered measured support for the idea of studying how to block sunlight from hitting Earths surface as a way to limit global warming, in a congressionally mandated report that could help bring efforts once confined to science fiction into the realm of legitimate debate.

The White House report released late Friday indicates that the Biden administration is open to studying the possibility that altering sunlight might quickly cool the planet. But it added a degree of skepticism by noting that Congress has ordered the review, and the administration said it does not signal any new policy decisions related to a process that is sometimes referred to or derided as geoengineering.

About time. The knuckle-draggers still do not think global warming is a problem. I've seen attempts to discuss this issue derided in GD forum.

(19,564 posts)Dark surfaces like solar panels would radiate heat into the surrounding environment. This is the same reason why the Arctic is trapped in a death spiral; as the white ice melts, it exposes dark ocean water and tundra soil, which absorbs instead of reflects solar radiation. More ice melts, more ocean and soil exposed, until no ice remains (should hit that point around 2035-2040 now).
To cool the poles, you need to deploy reflective and/or white material, but solar panels can't by their very nature be reflective.
