Two Ohio State University researchers spent months scouring through old expedition logs and reports, and reviewing 70-
year-old maps and photos before making a surprising discovery: They found that the effects of the current warming and
melting of Greenland 's glaciers that has alarmed the world's climate scientists occurred in the decades following an abrupt
warming in the 1920s. Their evidence reinforces the belief that glaciers and other bodies of ice are exquisitely hyper-
sensitive to climate change and bolsters the concern that rising temperatures will speed the demise of that island's ice fields,
hastening sea level rise. [Source: Ohio State Univ. Press Release]
