22-year Sea Level Rise - TOPEX/JASON

Satellite measurements show how sea level is changing around the world. Learn more about the causes of sea level rise and how sea level has changed over the last two decades in this video. Sea level changes detected by satellites between 1992 and 2014 are shown on this map. Cooling waters off the west coast of the U.S. have led to a drop in sea level in this part of the world. Scientists attribute the rise in sea level in the western Pacific Ocean to winds and ocean currents piling up warm water in the region.

Sea Level Rising Inteview with Tom Wagner Earth’s rising seas are some of most visible signs of our warming planet. Over the last 20 years, NASA satellites, airborne missions and field campaigns show a steady rise in global sea levels as the world’s polar ice sheets melt. As the Earth continues to warm, new research suggests sea levels could rise by as much as several feet in the next 100 years. Sea level rise is one of the biggest environmental challenges of the 21st Century, and NASA research is helping us understand how much our oceans will rise, and how fast that will happen. Hear from NASA scientists about the latest research on rising sea levels and melting polar ice. See surprising new views of ice loss in Greenland and Antarctica, and talk about the consequences of our rising oceans.Sea Level Rise Gallery.Material from the August 26, 2015 teleconference is here.
