> 3.8W/m2 total variation.
Now multiply that with the surface of the earth, morons. See the total energy balance, idiots. Only 0.9W/m2 is absorbed by the earth and contributes to the so called "global warming" you talk so much.

Jeez you are such idiots. Btw, you do know that even without the Sun you could have warming, right? The nuclear thorium and uranium reactions happening inside earth's core release a lot more than you think. It's almost half of the total energy received directly from the Sun. Venus is much more colder than expected (-157 Celsius) but you morons don't ask yourselves why. Do the math.

I had exactly the same idea in 2005. You need a 500 km array orbiting around L1 to deflect or absorb 0.5% of the total radiation. That could trigger ice ages (the big ones, correlated with Jupiter's orbital plane - every 26.000 years), and small ones as well (the ones that appear every 8-10.000 years).

0.5% is enough. You don't need much more than that, because the whole Earth will be in penumbra (think of a partial eclipse of the Moon).
