U.S. Coastal Cities at Risk from 3-Meter Sea Level Rise
Scientists are raising alarms about the potential collapse of Antarctica's Thwaites Glacier, also known as the 'doomsday glacier,' which could lead to a dramatic rise in global sea levels. According to Newsweek, the glacier's instability could contribute to a 3-meter (nearly 10-foot) sea level rise over time, inundating major U.S. coastal cities. NOAA projections indicate that areas such as New York City, Florida, and parts of California would face severe flooding risks. The glacier, which has been losing ice at an accelerating pace, is held back by an ice shelf and a seafloor hump, both of which are showing signs of weakening. If these barriers collapse, the resulting sea level rise could redraw coastlines and threaten critical infrastructure.
