@deprecated_ii They should build giant peltier coolers that are powered by absorbing the excess heat of the earth and shooting it into space using a laser.

@Elliptica @deprecated_ii It's be a lot more effective to extract the excess CO₂ from the atmosphere and bury it, but that's very expensive to do, to do anything at all against the scale of CO₂ release.

@Suiseiseki @deprecated_ii laser beams it is then.

@Elliptica @deprecated_ii Peltier's coolers are unfortunately very polluting and very expensive to construct at small sizes, let alone square km size.

How one side tends to freeze despite not that much heating on the other, means very little electricity can be generated in practice.

Lasers have the problem of how the atmosphere will absorb 99.99999999% of laser light - microwaves would be far more successful, but would also have the problem of cooking people and birds who stray too close.

@Suiseiseki @deprecated_ii Well, develop some other way to passively extract heat and turn it into electricity. Sterling engines I guess.

There is a window in the near infrared that would be ideal for a laser.
