The Fastest Rising Sea Levels in America 🌊

Key Takeaways

• Coastal cities, including Grand Isle, Louisiana and Rockport, Texas saw the highest sea level rises in 2024.
• Since 2010, sea levels in Grand Isle have risen seven inches—with Louisiana seeing one of the fastest rate of land loss globally.
• In southeastern Virginia, sea levels are not only rising but land is sinking at a notable rate, further compounding the issue.

Gulf Coast Sees the Fastest Rise

Sea levels are rising at the sharpest rate in the Gulf Coast, with these areas particularly hit by high tide flooding.

Among the primary causes is the melting of glaciers in Greenland.

By contrast, sea levels are falling at the sharpest rate in Juneau, Alaska, at 13.7 millimeters in 2024.

This too is driven by melting glaciers—but instead it is causing the land to rise given the loss of glacier weight.
