I’m against doing to much massive modifications to “fix it”, until we know for a fact that there is something to be fixed, and that the fix actually makes things better.
I’m not convinced that an extra half-degree of heat is a bad thing overall. It clearly is for the rich liberals that have populated the coastlines that might lose some of their beachfront property.
More CO2 means more green plants. That and a tad more warmth might mean a lusher nature. It’s not like the earth was designed by an idiot like Algore.
And for the beaches? The urf has reportedly been making them fluctuate for countless millennia. If they move, the wealthy will just have to move too. That’s the urf for ya. Mightier than we are.
