The L1 LaGrange point is NOT a place that something can be hung and remain

Thanks for quantifying the impracticalness of using the Lagrangian points
with a huge structure. These points have become what I call a "Hollywood
magnet of Science". People who do not know much of the subject of Earth
AirConditioner immediately fall into this Hollywood-Science of dreamy ideas
using the Lagrange points.

Question BZ, since David Smith is puzzled by this question. How much of the
present day Global Warming can be attributed to the ozone depletion? I am
guessing it is anywhere from 3% to perhaps (a stark surprize) as large as
50%.

What I mean is that if we replenished the ozone in the layers of the
atmosphere we can cut present day Global Warming by 50%. And if I am lucky,
we can even beckon the initiation of another Ice Age if we replenish the
upper atmosphere with ozone to its maximum carrying capacity within practical
means even though we have an ongoing GlobalWarming via greenhouse gases.

So I wonder, BZ, if you have your fingers on the best available data as to
how much ozone depletion contributes to Global Warming.
