Will the Greenland Ice Sheet be gone by the year 2200 and sea level rise 23 feet?
Americans will do nothing different significantly about energy consumption unless cheaper new energy technologies appear in the next 50 years or sea level rises at least six inches. Humanity is poised to burn more fossil fuels in the next century than has been consumed until now. A new billion Indian, Chinese and third-world middle-class consumers, high energy-consumption individuals, will want the “American Dream.” America's answer to their desire for “cheap” energy will be to provide natural gas and coal.
The rapidly thinning Greenland ice sheet is due to soot from forest fires, to dark pigments created by organisms growing on the glaciers to increased melting caused by enhanced absorption of sunlight by melting ice and exposed rock. However, recent studies in the journal Nature indicate that the ice sheet will not disappear completely even if temperatures rise eight degrees. The major unknown at this point is how much the Antarctic ice sheet will melt in response to global warming.
However, if by 2200 sea level rises as little as 10 feet, many port cities will have to be abandoned e.g. New Orleans; much of Florida and Bangladesh will disappear. To protect or rebuild the ports world wide will take over one hundred trillion dollars---all thanks to “cheap” fossil fuels.
