Memories of the 28th Century

This is part three of a series of blog posts on reversing global warming. In the first part I proposed trying iron dust on the oceans to cause phytoplankton blooms that would eliminate atmospheric CO2, which would (in theory) reduce global warming. The second method would be to cut down on heating from the Sun. And this third part is about cheaper ways to reduce the amount of sunlight reaching the Earth.

In addition to the methods for shielding the Earth from the radiation from the ...

This is part two of a series of blog posts on reversing global warming. In the first I proposed trying iron dust on the oceans to cause phytoplankton blooms that would eliminate atmospheric CO2, which would (in theory) reduce global warming. The second method would be to cut down on heating from the Sun.

It is obvious that reducing the amount of solar radiation reaching the Earth would lower the temperature of the Earth. My suggestion is not new. Others have suggested shielding the ...
