OK, OK, OK, maybe the physics here won’t work. And the scale might be impossible, too. But if sea levels will rise because of melting ice sheets, how about creating some new ones? Put snow machines all over Greenland, and maybe Alaska and Siberia, too. Maybe even on icebergs at the North Pole. Pile up enough snow, it turns to ice, makes whole new glaciers. OK, OK, OK, these things would generate heat if powered by fossil fuels. But how about harnessing wind, solar or ocean-convection energy to power these machines? To help pay, maybe create some wild new ski resorts for the super-adventurous.
