![]() Rising concentrations of greenhouse gases in Earth's atmosphere increase the temperature of air and water, which causes sea level to rise in two ways. Given the large changes we are seeing in the ice sheets today, that's not likely." "Our extrapolation assumes that sea level continues to change in the future as it has over the last 25 years. ![]() "This is almost certainly a conservative estimate," Nerem said. 12 in the journal Proceedings of the National Academy of Sciences. The team, driven to understand and better predict Earth's response to a warming world, published their work Feb. ![]() If the rate of ocean rise continues to change at this pace, sea level will rise 26 inches (65 centimeters) by 2100 - enough to cause significant problems for coastal cities, according to the new assessment by Nerem and colleagues from NASA's Goddard Space Flight Center in Greenbelt, Maryland CU Boulder the University of South Florida in Tampa and Old Dominion University in Norfolk, Virginia. Global sea level rise is accelerating incrementally over time rather than increasing at a steady rate, as previously thought, according to a new study based on 25 years of NASA and European satellite data.
