PNAS Study Confirms Acceleration In Sea-Level Rise; At Least 2-Foot Global Rise By 2100, Maybe More

The rate of sea level rise is accelerating so fast that some coastal communities could confront an additional 4 inches per decade by the end of the century—a growing concern now confirmed by thorough measurements from space.

At that rapid pace of change, vulnerable communities might not be able to keep up. Storm surges will increase erosion and damage homes, businesses and transportation infrastructure in some areas. In other places, seawater will intrude on freshwater aquifers. In South Asia and the islands, people will lose the land where they live and farm. And the changes will arrive much faster than they do today.

Scientists have been warning about this speed-up for many years based on computer climate simulations. A new study released Monday confirms the modeled trend with a detailed analysis of satellite observations spanning a quarter of a century.

The findings, published in the Proceedings of the National Academy of Sciences, reinforce the outlook that average global sea level is likely to go up at least 2 feet by the end of this century compared to 2005 levels.
