Greenland

Climate change led to accelerated melting of Greenland’s ice sheet during the past half-century, scientists said in a study that adds to evidence suggesting sea levels will rise faster than expected. Global warming has led to a “significant increase” in Greenland summer warmth and ice sheet melt and runoff since 1990, according to the study, published Jan. 15 in the Journal of Climate. In a review of ice thaw from 1958 to 2006, scientists determined that the five biggest melts have occurred since 1995. (Bloomberg)
