Agree, but only somewhat. It's not clear that we are actually short of sunlight to grow a lot of plants in a lot of places. Sure, places with short growing seas

Agree, but only somewhat. It's not clear that we are actually short of sunlight to grow a lot of plants in a lot of places. Sure, places with short growing seasons would have less yield, but, cooling the planet would also make more equatorial latitudes a bit easier to farm in for some crops by reducing the irrigation needs. My personal favorite geo-engineering approach, though, is iron-seeding parts of the pacific to create large plankton blooms. to me, this seems substantially less risky.
