Coastal communities across the U.S. are seeing some of the fastest sea level changes ever recorded — and a new visualization brings those shifts into sharp focus, per Visual Capitalist. 

According to data compiled by the Virginia Institute of Marine Science (VIMS), places like Grand Isle, Louisiana, and Rockport, Texas, are experiencing dramatic rises in sea level that could reshape how — and where — we live in the future.

What's happening?

A new report card from VIMS tracks sea level changes at 36 U.S. coastal locations. In 2024, Grand Isle topped the list with sea levels rising by 8.2 millimeters per year — part of a staggering seven-inch increase since 2010. Rockport, Texas, and areas in southeastern Virginia are close behind, with some regions also facing the added challenge of sinking land.

These changes are largely driven by the warming of our planet. As dirty energy sources like gas, oil, and coal continue to pollute our atmosphere, they trap more heat, which in turn contributes to glacier melting in places like Greenland and Antarctica. That meltwater eventually raises sea levels around the globe.

Meanwhile, in parts of Alaska, sea levels are actually dropping — but not for a comforting reason. In Juneau and Yakutat Bay, melting glaciers are causing the land itself to rise, with sea levels falling by over 13 millimeters. It's a startling reminder of how much the Earth's surface is shifting in response to our actions.

Why is sea level rise concerning?

Rising sea levels don't just threaten our coastlines — they endanger homes, raise insurance costs, worsen flooding, and increase the risk of storm damage. In Grand Isle, the average home insurance premium is a jaw-dropping $11,000 per year, due in part to worsening flood risk. Southeastern cities like Norfolk, Virginia, are also bracing for more frequent high-tide flooding and infrastructure damage as land sinks and water rises.

Experts warn that if this trend continues, millions of Americans could be displaced or face skyrocketing costs to adapt their homes and neighborhoods to these new realities.

What can be done about this?

Fortunately, there are ways we can reduce our impact and prepare for what's ahead. Supporting policies that shift us away from dirty energy and toward more affordable, less-polluting alternatives like solar and wind power is a powerful first step. Organizations like the American Flood Coalition are also pushing for smarter infrastructure and coastal protections nationwide.

Homeowners can take action too — by improving flood resilience with raised foundations, natural landscaping, or even installing solar panels with battery storage. These steps don't just help protect homes during extreme weather events — they also reduce monthly energy bills. EnergySage offers a free tool that lets you compare quotes from local installers and potentially save up to $10,000 on solar upgrades.

Sea level rise might seem like a distant issue — until it starts lapping at your doorstep. But by staying informed and taking small, proactive steps, we can help protect our communities and create a safer future for everyone.
