Rising sea levels could swamp the US coastline by 2050, NASA predicts

Sea levels are likely rising faster than previously thought, meaning low-lying coastal cities in the U.S. could flood far more regularly in the coming decades, a NASA study has revealed.

According to the study, which analyzed three decades of satellite observations, by 2050, sea levels along the coastlines of the contiguous U.S. could rise as much as 12 inches (30 centimeters) above current waterlines, the research team said in a statement (opens in new tab). The Gulf Coast and Southeast are expected to be most severely impacted, and will likely experience increased storm and tidal flooding in the near future, according to the study, published Oct. 6 in the journal Communications Earth & Environment (opens in new tab).
