Imagine an alien with extreme tech capabilities is pointing a heater at the earth. Now react appropriately:

- model and build temperature resistant crops.

- harvest energy from the heat

- create resilience in social governance to enable safer movement of people with education to enable quick adaptation.

- build energy resilience everywhere - including in and especially in desert areas.

- more constructive ideas.

Don’t:

- guilt your children into not having children to “protect the planet” from themselves.

- use your megaphones to racketeer the people making your food into paying you “indulgences” for producing useful stuff for you and other humans (thus making stuff needed by humans more expensive)

- use the problem to gather around with rich friends on fuel-hogging private jets while making others eat less to reduce emissions.

If you’re suffering from obesity, is it helpful to imagine an alien somehow beaming calories into your stomach?

>harvest energy from the heat

This is not a thing. This is just entropy.

we have this interesting thing called a thermoelectric generator,that converts thermal gradient to electromotive force.

so yes harvesting energy from "the heat" is a thing, if you gate the dissipation of heat from the source to a sink.

these are already used to scavenge heat to drive fans, lights, phone chargers, and pumps.

What “thermal gradient”??? Climate change exists within a greenhouse. We are raising the ambient temperature. Even if you could do something like that at scale (ha!), I’d love to know where your continuous cold sink comes from in an enclosed system.

Except it's not aliens, it's us. Maybe stop doing that.
