We can't even control our own climate yet

The latter.

It is not outside the realm of plausibility to get small oceans, the ability to go outside without a spacesuit, and some plant life, but Mars will always be cold and dry relative to Earth.

Consult Martyn J Fogg's Terraforming for an in-depth scientific analysis of the concept for an academic audience.

crash the largest asteroid belt objects objects on Mars and and you will at least get new craters and a reasonably big lake
Only problem, our technology is not advanced enough to to this.

Difficult, but possible.

Venus would be better. It has 0.9 Earth gravity, it's warmer, and it's closer by.

Even if an atmosphere could be created on mars, would radiation still be a problem due to the lack of a magnetic field?

Terraforming is retarded, simpler to just become machines.
In fact, why the fuck would you even stay in gravity well. Find yourself a nice asteroid, remodel it in a nice solar panel, and chill out for the next millions years, masturbating your virtual robodick while browsing the extranet.

I mean, staying on those big "PLEASE STRIKE ME WITH AN RKV" targets is really dumb.

I dare say that getting rid of thousands of tons of gas is harder than artificially thickening a planet's atmosphere. And no, I don't buy the venus balloon idea at all.

Given the extent to which we'd need to thicken Mars' atmosphere, no, I don't think it'd be quite the problem that some imagine it to be. Here on Earth, the atmosphere's thickness helps to shield radiation as well.

I don't have any math to back it up, but because Mars has 1/3 of Earth's mass, doesn't that mean that its atmosphere would need to be considerably thicker than Earth's to get the same levels of atmospheric pressure we see on Earth? If so, that means that it would also be much more capable of shielding radiation than our atmosphere is.

The other problem frequently cited is atmospheric blowoff by solar wind, but that process is so slow that if we have terraforming technology, maintaining the atmosphere would be no issue. In fact, the mere presence of a large industrial population would likely offset the blowoff and then some, if you look at the volume of thickening gasses we exhaust here on earth.

>>8005121
Possible, but that'd take a few 1000 years and lots of bombardment from ice comets/asteroids or whatever the source would be from.

The biggest thing is keeping the atmosphere on it. You are better off trying to convert another planet or moon that already has an atmosphere.
