TL;DR: the total energy produced by humanity in a year.
Or if you want to do it in let's say 20 years, 5% of the total power output.
It's way less than that. 2.39x10^20 is around 4% of 5.8x10^21. Not even close to "almost as much". Looks like the authors don't know their powers of 10. So if we dedicate 5% of the total energy for one year it could theoretically be done.
Assuming a 100% efficient CO2 capture system...
Here's an actual carbon capture system, I have mo idea how efficient or practical it is.
That doesn't sound too bad.
Technically yes, but politicians start freaking out as it would lower GDP a few percent too.
I think the technical term is: But muh ecomnomie!
They're going to say that anyway when the real cost of warming hits. Calculation about that says GDP -30% to -50%. But that's for the next legislature I guess.
Yes, for politicians the cost is always lower to kick the can into the next administration's term. Unfortunately it becomes more and more expensive for the rest of us.
In the end, they'll have kicked so many cans down the road that the huge pile is blocking the way.
