“Global sea level rise has been accelerating in recent decades, according to a new study based on 25 years of NASA and European satellite data. This acceleration has been driven mainly by increased ice melting in Greenland and Antarctica, and it has the potential to double the total sea level rise projected by 2100, according to lead author Steve Nerem, a scientist at the Cooperative Institute for Research in Environmental Sciences (CIRES) and the University of Colorado.
If things continue to change at the observed pace, sea level will rise 65 centimeters (26 inches) by 2100, enough to cause significant problems for coastal cities. The team—comprised of scientists from NASA’s Goddard Space Flight Center, the University of Colorado, the University of South Florida, and Old Dominion University—recently published their work in the journal Proceedings of the National Academy of Sciences.
“This is almost certainly a conservative estimate,” said Nerem, who is a member of NASA’s Sea Level Change team. “Our extrapolation assumes that sea level continues to change in the future as it has over the last 25 years. Given the large changes we are seeing in the ice sheets today, that is not likely.”
