There are two main elements to observe when assessing sea-level rise. One is the loss of the ice on land, e.g., melting mountain glaciers and inland ice sheets on Greenland and Antarctica, and the other is that the sea will expand as it gets warmer. The more its temperature increases, the faster the sea will rise. Researchers at the Niels Bohr Institute, University of Copenhagen have constructed a new method of quantifying just how fast the sea will react to warming. Their comparison of sea-level responsiveness in models with historical data shows that former predictions of sea level have been too conservative, so the sea will likely rise more and faster than previously believed. The result is now published in the European Geosciences Union journal Ocean Science.
