- an aspirational goal of holding warming to no more than 1.5C
Big fans at the poles?
Huge air conditioners stationed at strategic points around the world?
Building a huge sun blocker in the upper atmosphere?
Speed up the Earth's rate of turning on its axis, so the globe gets sun for a lesser amount of time?
Put a big hose with a large sprayer on the Moon and have it shoot water toward Earth to cool it?
Fine cows for farting?
Fine senators, other politicians, and global climate change hoax pushers for bloviating?
