What is the potential impact of the Thwaites Glacier collapse on sea levels?

The collapse of the Thwaites Glacier could raise global sea levels by two feet over several decades.

Which regions are most vulnerable to rising sea levels from glacier melt?

Coastal cities worldwide are at risk, with a particularly acute threat to rapidly growing urban areas in Asia.

How much might it cost to protect coastal cities from sea-level rise?

Protecting certain areas, like parts of New York City, could cost over $52 billion, with adaptation costs being astronomical for many places.

Antarctic Ice Shelf Collapse: Coastal Cities Face Flood Doom

A potential collapse of Antarctica's Thwaites Glacier could trigger a significant acceleration of global sea-level rise. Scientists are studying the glacier, which is melting rapidly. If it disintegrates, sea levels could increase by two feet over several decades, affecting millions globally.

Coastal cities, especially in Asia, are acutely vulnerable to this rise. Shanghai faces increased impact for millions of residents, while Bangladesh's capital, Dhaka, will struggle with adaptation due to its low-lying geography and rapid population growth.

In the United States, the cost of adaptation is immense. Protecting New York City alone might cost over $52 billion. Despite these threats, populations continue to grow in vulnerable coastal areas like Miami.

Further research into Thwaites's collapse timing is crucial for adaptation efforts. Past decisions, including the abandonment of climate research and promotion of fossil fuels, could exacerbate the glacier's melting and hasten future sea-level rise.
