U.S. coastline to sink by up to 25 inches by 2050

The NOAA report warns of a significant rise in sea levels along the US coastline, projecting an increase of 10 to 12 inches over the next 30 years, comparable to the rise over the past century. This rise will vary regionally due to differences in land movement, with the southeastern US expected to experience more significant changes. Galveston, TX, could see a rise of 25 inches, while Seattle may only see 9 inches. The report highlights increased risks of storm surges and sunny day floods, particularly in Galveston and East Coast cities. Oceanographer William Sweet emphasizes that the most severe impacts of ice sheet melting will manifest at the century's end.

What is the projected average rise in sea levels along the US coastline over the next 30 years?

• 10 to 12 inches

• 5 to 7 inches

• 15 to 17 inches

• 20 to 22 inches

Why does the NOAA report suggest that sea level rise will vary regionally along the US coastlines?

• Because of different rainfall patterns

• Due to differences in the relative movement of land height

• Due to differences in ocean currents

• Because of varying temperatures

Which US city is expected to experience a 25-inch rise in sea level?

• Seattle

• Miami

• Galveston, TX

• New York

What are 'sunny day floods' as mentioned in the NOAA report?

• Floods occurring during high tides without storms

• Floods caused by heavy rainfall

• Floods due to hurricanes

• Floods caused by melting glaciers

According to the report, when will the effects of the current melting of Earth's ice sheets start to become significant?

• By the mid-21st century

• By the end of this century
