It seems to me, although I must admit that I have not done the math,
this would need to be reduced or you would have a planet like the
McDLT with a hot side and a cool side.
I suspect it's easier to put up orbiting shades (and, eventually, mirrors).
We did some of this math for the Transhuman Space: In the Well playtest.
There's a lot of problems with terraforming venus; just adding water
isn't enough. With a lot of resources spent on building a giant shade,
you can probably cool things down enough to allow starting with the next
step in several hundred years. Actually binding all that CO2 is the work
of millennia if you're using means that are powered by solar energy, and
all other options require ridiculous amounts of hardware.
