Flooding Has Increased By 200-400% In The Last 20 Years2
Although the sea level has risen by 6.5 inches since 1950, nearly half of it (3 inches) has occurred in only the last 20 years. This small increase in sea level has caused a 200-400% increase in flooding nationally. Minor increases of even an inch in the sea level are causing real problems everywhere—from Texas to Florida to New York. Higher seas mean more water and more flooding during high tides, hurricanes and rainstorms.
Some Regions Have Even Faster Rates Of Sea Level Rise
Enter Your State
Though sea level rise and flooding are increasing in all coastal communities across the United States, the increase is at different speeds. Select a state below to find out about how the historical rate, forecast, causes, and solutions are different in each.
We Know This Because Sea Level Is Measured Every 6 Minutes
To monitor local sea level, scientists use different equipment like satellites, floating buoys off the coast, and tidal gauges to accurately measure the local sea level as it accelerates and changes.
Coastal Towns Are Already Spending Billions Of Dollars Today
In low lying places, roads have been raised, seawalls and pumping systems have been installed, and fresh water wells have been relocated. Some cities have sufficient resources to deal with this problem while others do not. We need solutions at the individual, local, state, and federal levels to protect our coastal communities.
