Scientists began an expedition to Antarctica to study Thwaites Glacier. This glacier is melting quickly. If it completely breaks apart, global sea levels could rise by two feet. This change could affect millions of people worldwide.
The maps show cities at risk from this rising water. Many low-lying areas are in danger. As Thwaites Glacier melts, other glaciers nearby could also break apart and add more water to the oceans. This would make coastal cities even more vulnerable.
Cities in Asia face the biggest risks. Fast-growing areas are at high danger. For example, Shanghai has many people living below sea level. If sea levels rise, more than four million people could be affected.
Protecting cities from flooding will cost a lot of money. For New York City, plans could cost over $52 billion. Some cities may not be able to afford these protections. Places like Bangladesh are struggling with rising tides and need help to prepare for future flooding.
