Science: Sea levels are rising at their fastest rate in 2000 years

Global sea levels appear exquisitely sensitive to changes in temperature and greenhouse gas levels, according to a set of new studies that examines up to 6 million years of climate change data. The four papers, published today in the Proceedings of the National Academy of Sciences(PNAS), illustrate the growing power of computers to simulate complex interactions between climate, polar ice, and the planet’s oceans. They also underscore the effects that rising greenhouse gases and global temperatures could have on future sea level.

“The big takeaway is that the modern rate of sea level rise in the 20th century is faster than anything we’ve seen in the previous two millennia,” says Benjamin Horton, a Rutgers University, New Brunswick, in New Jersey geologist who helped direct one of the studies. “This isn’t a model. This is data.”
