Arctic Sea Ice Melt and Shrinking Polar Ice Sheets: Are Observed Changes Exceeding Expectations?

This forum was aired on C-SPAN.

Is the Arctic sea ice cover melting faster than expected? If so, what are the contributing factors and why was the rate of melting unanticipated? How much sea ice cover has been lost in terms of extent and volume? What are the implications of both the loss of sea ice and the rate of loss? Is the Greenland ice sheet losing its mass faster than anticipated? If so, what are the contributing factors and why was the rate of loss unanticipated? What are the implications of continued accelerated ice loss from the Greenland ice sheet with respect to Sea Level Rise? Is the Antarctic Ice Sheet getting bigger or smaller and by how much and how fast? Are there parts of the Antarctic ice sheet that are gaining mass and parts that are losing mass? If so, what are the contributing causes? What are the implications of continued ice mass loss in Antarctica, especially the decay of ice shelves?
