These images show projected future sea levels at Cattedrale di Sant'Agata (Catania Cathedral) in Catania, Italy 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.
