Melting ice in the Arctic revealing new coastline geography in Greenland

The New York Times has another article on the impacts of global warming, this one discusses how the melting of glacial ice is exposing new land area and changing our knowledge of the coastline geography of Greenland. This is illustrated by the example of a recently-identified island, which was thought to be part of a peninsula of land under the ice until the ice melted and a channel of seawater was exposed between the island and the mainland. As the melting continues, there will surely be more efforts to map these new topographic features, even though their exposure through ice melt is continuing evidence that the climate is rapidly changing. This may also impact other disciplines like archaeology, since sites that were once occupied in past times when the earth was warmer may now be exposed again by melting ice.
