So you think it would be cheaper to build sea walls around all our coastal cities, resettle millions of people living on islands around the world and completely moving all centres of agriculture out of the now deserts into former tundra areas than reducing carbon emissions? Stabilising at 550ppm CO2 would cost about 3% of global GDP, around $1.5tr, or about what the US has spent on war in the last decade.

Craziness.
