Surging Seas: Seeing Choices
This map shows sea levels locked in by different amounts of carbon pollution, according to recent scientific research. If we burn enough fossil fuels to heat the planet by 4°C—continuing a path of unchecked pollution—we could drown coastal cities worldwide. If we make a rapid transition to a global clean energy economy and achieve the main goal of the Paris Agreement, limiting warming to 2°C, some cities will be saved. If we go faster and further to achieve the most ambitious Paris goal, 1.5°C, the outlook improves dramatically. Still, it is sobering to map the challenges following after 1°C of warming, a level we have just passed.
According to Climate Central’s analysis, 470 to 760 million people (central finding, 627 million) live on land that would be condemned by 4°C warming. The number drops by more than half for 2°C, and more than half again for 1.5°C.
