Let's say Hansen is right???? Let's give him the benefit of being right in this thread. We really do see warming at .25-.3c per decade all the way to 2100. What would you suggest us do? Let's say we get 3 to 4c warmer than today by 2100. A few idea's -Build sea walls around cities that are within 5 feet of sea level. -Move cities, towns, etc to higher ground -Work on toughing up grains, etc to sustain themselves through drought and flood What else do we do?
