Siphoning 2% of the sun's radiation sounds easy until you think about how much fucking energy that is. If we back it off to like 1% we can catapult ourselves onto the kardashev scale. #10 would still be at play, and it would be even more disastrous than before!
Well it says "siphoning", but I think it rather refers to just blocking the light.
Which is something we've actually thought about and which definitely doesn't have any global risks attached to it.
