University of Colorado at Boulder researchers studied 25 years of satellite data. They concluded that global sea level rise is not cruising along at a steady 3 mm per year, as was previously feared. It’s accelerating. Every year.
If the oceans continue to rise at this pace, sea level will rise 65 cm (26 inches) by 2100.
“It’s a big deal” because the projected sea level rise is a conservative estimate and it is likely to be higher, said the lead author, Steve Nerem of the University of Colorado.
Other scientists said even small changes in sea levels can lead to flooding and erosion. “Any flooding concerns that coastal communities have for 2100 may occur over the next few decades,” said Katy Serafin, a coastal flooding expert at Oregon State University.
