Sea levels are rising much faster along the U.S. East Coast than they are around the globe, putting one of the world's most costly coasts in danger of flooding, government researchers report. U.S. Geological Survey scientists call the 600-mile (965-kilometer) swath a "hot spot" for climbing sea levels caused by global warming. Along the region, the Atlantic Ocean is rising at an annual rate three times to four times faster than the global average since 1990, according to the study published Sunday in the journal Nature Climate Change. It's not just a faster rate, but at a faster pace, like a car on a highway "jamming on the accelerator," said the study's lead author, Asbury Sallenger Jr., an oceanographer at the agency. He looked at sea levels starting in 1950, and noticed a change beginning in 1990. Since then, sea levels have gone up globally about 2 inches (5 centimeters). But in Norfolk, Virginia, where officials are scrambling to fight more frequent flooding, sea level has jumped a total of 4.8 inches (12.19 centimeters), the research showed. For Philadelphia, levels went up 3.7 inches (9.4 centimeters), and in New York City, it was 2.8 inches (7.11 centimeters). Climate change pushes up sea levels by melting ice sheets in Greenland and west Antarctica, and because warmer water expands. Biden, Warnock, and the resurgence of the liberal Christian
Computer models long have projected higher levels along parts of the East Coast because of changes in ocean currents from global warming, but this is the first study to show that's already happened.
