WH opens doors to study blocking sun's rays to slow global warming

8. This would make climate change worse by altering the albedo effect

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.
