Mapping Choices: Sea Level Rise Around the Globe

Program Summary

Carbon emissions causing 4°C of warming — what business-as-usual points toward today — could lock in enough sea level rise to submerge land currently home to 470 to 760 million people, with unstoppable rise unfolding over centuries. At the same time, aggressive carbon cuts limiting warming to 2°C could bring the number as low as 130 million people. These are the stakes for global climate talks December in Paris.

Our analysis details the implications of different warming scenarios for every coastal nation and megacity on the planet, and our globally searchable Mapping Choices tool maps them. We have also published Google Earth fly-over videos and KML contrasting these different futures for important cities around the world, and printable high-resolution photorealistic images of select global landmarks. We have made these visualizations embeddable and downloadable. These are the stakes for global climate talks, in one video.
