Re: USA urges scientists to block out sun

I studied meteorology at the University of East Anglia ,England in
1980 and was given the problem of solving global warming.
I came to the decision that preventing the release of CO2 would be
almost impossible with the politics and short term thinking of the
worlds people and thus another solution would have to be found.
The two solutions I came up with were either to some how get more CO2
absorbed by the sea by techniques like stimulating plankton and algae
growth (addition of key nutrients) , or to construct a sunshield at
L1.
I proposed using a rotating bolo space elevator to transport the
materials up from Earth and then have several large rotating shields
of very thin material. These would have thrusters to ensure their
position is maintained.
One of the advantages of this sun shield technique is that it starts
working as soon as the first piece is in position.
An alternative simpler solution , but requiring more mass to be
transported to L1 is to have millions of un-controlled Y shaped
objects that do not require to be positioned accurately relative to
the Earth.
