The white, reflective barrier protecting our northern polar region from the heat-amplifying effects of human-caused warming took a severe blow today. The National Snow and Ice Data Center’s sea ice area measure essentially fell off a cliff as values plummeted by more than 286,000 square kilometers. That’s an area of ice the size of Nevada lost in a single 24 hour period. A state-sized region flipping from white, reflective, cooling ice, to dark, heat-absorptive water.

Sea Ice Area Goes Vertical

Overall, the sprawl of sea ice fell to 9,984,000 square kilometers or a negative 907,000 square kilometer anomaly vs the already low 1979 to 2008 mean. The fall was rapid enough to bring sea ice area to within striking distance of new record lows for the date…
