Boulder scientist teams on study probing implications of ice sheet's demise

Flying over the remote during research at the Barnes Ice Cap on Baffin Island in 2009, a Boulder scientist saw dark where there should have been white.Closer inspection revealed that what Gifford Miller spotted was the remnants of a 1963 geological camp that had been buried for decades by snow and ice. Long-abandoned tents and snowmobiles were being unveiled by melting of the ice cap, and that helped inspire a study that suggests a disturbing climate change signal.
