Inside the natural history museums of the world are billions of animal and plant specimens from birds, fish and beetles to flowers, mushrooms and grasses, all stacked, stored and preserved in jars and collection drawers. The rich and diverse collections could be critical to understanding how the Earth鈥檚 biodiversity is changing in the face of a growing human footprint 鈥� if only the information were easily accessible.

Last July, something unprecedented in the 34-year satellite record happened: 98 percent of the Greenland Ice Sheet鈥檚 surface melted, compared to roughly 50 percent during an average summer. Snow that usually stays frozen and dry turned wet with melt water. Research led by the Cooperative Institute for Research in Environmental Sciences now shows last summer鈥檚 extreme melt could soon be the new normal.
