"It contains a lot of units conversions and also astronomical facts that I needed for some research on moving Mars to a more temperate location."
lmfao, anywhere I can read more about McCarthy's plans for this?

Oh well.
I think it would be easier to just limit greenhouse gas emissions on earth.
Your point works pretty well considering that Venus has a a dense atmosphere unlike Mars.
The same technology could be used to reduce gw on the earth:
1. an orbiting sunshade
2. putting something in the atmosphere that makes it more reflective, like sulfur dioxide
I wonder how big a sunshade would need to be to reduce temps by, say, one degree. A specific location could be shaded by putting the shade in geosynchronous orbit. To finance the sunshade, put a Starbucks or Coca-Cola logo on it.
A single giant megaproject sunshade is not feasible. But it is possible to make many smaller ones, each diminishing insolation by just a few fractions of a percent.

Of course it would, but that's besides the point
Somehow I doubt our ability to do this strategically...
0. climate change has already entered an irreversible spiral
1. decades from now, the irreversible spiral having deepened and accelerated, civilization as we know it has been destroyed, leaving no authorities to do anything about climate change
2. decades to centuries from now, climate change makes earth mostly uninhabitable
3. hundreds or thousands of years in the future, if they weren't all dead, humans perhaps would have been able to maintain a self-sustaining colony of all for humanity another planet
there's not a realistic path for humanity to survive an earth-destroying asteroid, and there never will be
