The human fingerprints on coastal floods

Climate Central: There are human fingerprints on thousands of U.S. coastal floods -- and countless more the world over. We have known for a long time that sea level is rising. The link to global warming has been both intuitive and evident. Temperatures rise, and satellites watch glaciers and ice sheets shrink; networks of robotic buoys sample ocean waters as they heat and expand. We have also known that coastal floods are increasing. The link to sea level rise is clear. A higher starting level means that the...

American Icons Threatened by Sea Level Rise: In Pictures

Climate Central: Long-term sea level rise set in motion by near-term carbon emissions threatens major American icons. Here we present paired images showing how the Pentagon, the Wall Street Bull, and the Googleplex — symbols of American military, economic, and technological might — could fare under scenarios of business as usual vs. a sharp transition to clean energy. In the first image for each pair, we show projections of eventual sea level rise that would be locked in following 7.2°F (4°C) of warming from carbon...

Coastal Nations, Megacities Face 20 Feet of Sea Rise

Climate Central: If, as suggested by a comprehensive new review in the journal Science, 2°C of global warming will lock in at least 20 feet (6 meters) of eventual sea level rise, what would 2°C of warming (3.6°F) mean for the future and heritage of global nations and cities? It would mean a world we don't recognize, one losing more than 444,000 square miles of land, where more than 375 million people live today. China, the world's largest emitter of greenhouse gases, is home to by far the largest share of those...

How 2°C of Warming Could Reshape the U.S

Climate Central: If, as suggested by a comprehensive new review in the journal Science, 2°C of global warming would lock in at least 20 feet (6 meters) of eventual sea level rise, what would that warming mean for the future and heritage of the U.S.? It would mean a map we don't recognize: Louisiana would shed its boot, the Eastern seaboard would seriously retract, and the Bay Area would grow a second inland bay -- as the nation would lose more than 48,000 square miles of land, home today to 23.4 million people....
