"Sea level rise from global warming is well on the way to doubling the risk of coastal floods 4 feet or more over high tide by 2030 at locations nationwide. In the lower 48 states, nearly 300 energy facilities stand on land below that level, including natural gas infrastructure, electric power plants, and oil and gas refineries. Many more facilities are at risk at higher levels, where flooding will become progressively more likely with time as the sea continues to rise. These results come from a Climate Central combined analysis of datasets from NOAA, USGS and FEMA."
