Interglacial Warming Period and Rise in Sea Level

The National Aeronautics and Space Administration (NASA) has published a short article about a past warming period and an associated rise in sea level. The article summarizes the work of a team of scientists led by Andrea Dutton at the University of Florida (Dutton et al., 2015). The authors argue that an interglacial warming period 125,000 years ago reduced the Greenland and Antarctic ice sheets, leading to a six to nine meter rise in sea level. Dutton and her research team used proxy data from coastline sediments and tiny marine organisms called foraminifera to determine the change in sea level. The authors argue this data will be instructive to scientists attempting to predict the effects of anthropogenic climate change. The full article can be found here.
