The article Contribution of Antarctica to past and future sea-level rise by Robert M. DeConto and David Pollard is about the ice caps in Antarctica melting at a rapid rate. The extensive ice shelves in the Ross and Weddell Seas are about 1km thick at the grounding line and around a few hundred meters thick near the calving front. These ice sheets are eroding fast due to the oceans warming. The oceans are warming at rates faster than 10 meters per year. These ice shelves are also effected by atmospheric warming, causing meltwater on the ice-shelf surfaces which leads to thinning of the ice because of percolation. The Antarctica ice sheets are melting rapidly causing habitat loss to many species.

The question the authors are asking in this article is, will atmospheric warming soon become the dominant driver of ice loss? To collect the data the scientists used a model coupling ice sheet and climate dynamics which would be reports of acts and behaviors. The data analysis method is interval and ratio data. This research article was well written and easy enough for anyone to understand. The authors did a good job covering all the different ways that climate change is effecting the Antarctic ice sheets and there were no bias opinions. I found this research article very interesting but the part that stood out to me the most is how fast the sea ice is melting. This has so many effects of animals and organisms but it also affects us as humans because the more ice that melts, the more the sea level will rise.
