Coastal US sea levels will rise an average of a foot or more in the next 30 years, a new federal report warns. That's the fastest pace in 3,000 years.
The report predicts:
The 131.6 million people in the US who live within 60 miles of the ocean will face the worst effects from rising seas. That's according to the report published by the National Oceanic and Atmospheric Administration. But sea level rise will vary widely: 14-18 inches along the Gulf Coast, 10-14 inches on the East Coast, 6-8 inches on the Southwest coast, and 4-6 inches on the Northwest coast.
The report blames human-caused climate change. That's mostly due to emissions caused by burning fossil fuels. Unfortunately, the report calls the predicted sea level rise inevitable. That means drastically lowering emissions won't stop it by 2050.
But, the report says, curbing emissions would greatly reduce sea level rise from 2050 to 2100. Without that, sea levels could increase another 5 feet by century’s end. That would bring disastrous results.
Our Ocean | Timelapse in Google Earth
This time-lapse video uses Google Earth to show how climate change has impacted ice in the Arctic and how it may increase sea level rise in New York City, London, and Tokyo.
Sea Level Rise and Climate Change Demo
This lesson plan provides a podcast, student worksheet, and two hands-on experiments that demonstrate how melting land ice and the thermal expansion of water contribute to sea level rise.
Climate Change Inquiry Lab
Three laboratory experiments investigate factors that drive climate change: the increasing concentration of atmospheric carbon dioxide, sea ice and temperature, and the comparative effect of sea ice versus land ice melt on sea level rise.
