Some things we might do if we got desperate enough: scrub greenhouse gasses from the atmosphere technologically, geo - engineering to create cooling effects to offset greenhouse heating, [SLIDE 42] lots of

against tropical disease, new water
projects for flood control and drought management, dyke storm surge barriers, avoiding further development on flood plains in near sea level.
