These images show projected future sea levels at The Pentagon in Washington D.C., United States due to human-caused global warming under two different scenarios. Climate and energy choices in the coming few decades could set the destination, but the timing of rise is more difficult to project: these sea levels may take hundreds of years to be fully realized.
