The European Space Agency released this video on sea level rise on September 24, 2018. The video explains that – on average, as measured by satellites orbiting Earth – sea level has been rising 3.1 millimeters (0.12 inches) per year over the past 25 years. Melting glaciers and ice sheets, and the thermal expansion of sea water as oceans warm, are mainly responsible for the rise.
The rate of sea level rise has been accelerating in the past five years to nearly 5 millimeters (0.2 inches) per year. Jérôme Benveniste of ESA, who is featured in the video, called this “a strong acceleration.” He said:
By 2100, we could have a rise of 2 meters [6.5 feet].

Bottom line: A new ESA video on the rate of increase in sea level rise.
Deborah Byrd created the EarthSky radio series in 1991 and founded EarthSky.org in 1994. Today, she serves as Editor-in-Chief of this website. She has won a galaxy of awards from the broadcasting and science communities, including having an asteroid named 3505 Byrd in her honor. A science communicator and educator since 1976, Byrd believes in science as a force for good in the world and a vital tool for the 21st century. "Being an EarthSky editor is like hosting a big global party for cool nature-lovers," she says.
