Umm, akshually. The Martian atmosphere is already 95β„… CO~2~. Its cold because the atmosphere is so thin. Its thin because Mars does not have a strong magnetic field like Earth does, so solar winds can strip away bits of the atmosphere. Also, Mars only has about 0.38 times the gravity of Earth, making it easier for gases to escape.

Akshually akshually atmospheric escape is a very slow process and would take even a large atmosphere thousands or maybe even millions of years to disappear. You could add the atmosphere first and have plenty of time to figure out how to keep it second.

The atmosphere would still be a CO2 toxic hellscape, so we could only send billionaires there for a long time.

What if the second solution is some technology - godlike to people from our time - that could start spinning the core of Mars to create a magnetosphere? That might be more difficult with people already living there.

I've seen people restart core spinning on earth with nukes, might work on Mars too!

Millions of years? Good thing Mars is 6000 years old!

Wait... So if we just get rid of Earth's magnetic field, solar winds will solve global warming?

Crisis averted!

Ay, you beat me to it. I found this out as a kid after watching Total Recall. I ruined the movie for myself.

We could just send your mom, and that would fix the gravity situation.

And the gas situation amirite?!

Mars does not have a strong magnetic field like Earth does, so solar winds can strip away bits of the atmosphere.

I wanted to say the same. And furthermore I wanted to add that it's beside the point of the comic. But I still wanted to say it.

Exactly. And yet sci fi keeps wanting storms to happen on Mars.

But that is an easily solved problem. Take the design of the James Webb, substitute the super cooled infrared camera and replace it with a superconducting magnet setup. Fly this setup to L1 of mars and start global warming.

I didn't come up with that. Someone at NASA did. Years ago: https://astrobiology.nasa.gov/news/how-to-give-mars-an-atmosphere-maybe/

I know this is fiction, because it's unlikely for any of the senators to be able to check the science provided.
