She has conducted extensive research on the two largest masses of ice on Earth — the Antarctic and Greenland ice sheets — with the goal of understanding how these entities are shrinking and contributing to sea level rise as the planet's climate warms.

The Greenland and Antarctic ice sheets already appear to be shrinking «100 years ahead of schedule» as Penn State climatologist Richard Alley put it in March 2006.

Recent evidence of faster rates of global sea - level rise suggests that these projections may be too low.3, 4,5 Given recent accelerated shrinking of glaciers and ice sheets, scientists now think that a rise of 2.6 feet (80 centimeters) is plausible — and that as much as 6.6 feet (2 meters) is possible though less likely.16

The retreat of glaciers and shrinking of the Greenland ice sheet in the Arctic, for example, is predicted to cause significant sea - level rise, changes in the salinity of our oceans, and altered feedback loops that will make the Arctic warm up even faster.

The Arctic (North Pole) has shown the most rapid rate of warming, with dramatic effects such as shrinking of this region's glaciers, ice caps, ice sheets, and permafrost.

For example, the lower atmosphere and the upper layers of the ocean have also warmed, snow and ice cover are decreasing in the Northern Hemisphere, the Greenland ice sheet is shrinking, and sea level is rising (see Figure 1b).

But because the concentration of carbon dioxide is so much higher now than any time in nearly 1 million years, ice sheets are shrinking instead of growing.

Ice sheets and glaciers are shrinking, of course.

If it melted completely, it would raise global sea level by about 23 feet (7 meters).13 While the ice sheet is unlikely to disappear in our children's lifetimes, the pace of shrinking largely depends on what we do to limit future warming.14 (See Greenland ice sheet hotspot for more information.)
