Geoengineering could save the ice sheets - but only if we start soon

2. This spraying aerosols idea is the dumbest damn thing in the world.

Seriously, all it does is shade the Earth. Best case scenario is it does indeed stabilize the surface air temperature...for a while. But you have to keep spraying aerosols because they will fall out of the atmosphere at some point. Worse still, it treats only one aspect of AGW -and not the most important one.

In the meantime, for starters:
- we will keep emitting CO2 and other GHGs
- the oceans will continue to acidify
- sea ice will continue to melt (due to the warmer oceans)
- a bunch of other stuff I'm too lazy to type and/or look up

You get the idea. Spraying aerosols is a stupid, pointless idea.
