Climate and energy choices this decade will influence how high sea levels rise for hundreds of years.

These images show projected future sea levels at Torre Galp (Galp Tower) in Lisbon, Portugal 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.
