I just watched a video on how covering the Sahara in solar panels would change the climate and likely kill the amazon rainforest. Dangerous to play eith climate like that.
The laws of thermodynamics are inexorable - if something has arrived, somewhere it has gone from...Eggheads should focus their research on places where there has will loss rather than gain.
Solar parks with gigantic dimensions are particularly worthwhile in dry, inhospitable areas with many hours of sunshine. A study using weather models shows that the dark areas have an even greater effect on the environment.
