Konrad "Koni" Steffen (born 1952)[1] is a glaciologist and the former director of the Cooperative Institute for Research in Environmental Sciences at the University of Colorado Boulder, a position he held from 2005[2] until he took office as the director of the Swiss Federal Institute for Forest, Snow and Landscape Research on July 1, 2012.[3] He is known for his research into Arctic sea ice and the glaciers of Greenland, and how they are affected by global warming.[4] He has often traveled to Greenland to study these glaciers firsthand; for example, when studying Petermann Glacier for three weeks in 2004, Steffen did so from a camp set up 4,000 feet up the flanks of the glacier's ice cap.[5] He also operates a network of 20 weather stations on the Greenland ice sheet,[6] the first of which, Swiss Camp, he established in 1990.[7] He has argued that due to this ice sheet melting faster than anticipated, sea levels could rise by about 3 feet by 2100, considerably higher than the IPCC's upper limit of 59 centimetres (1.94 ft),[8] and that Greenland might lose all its ice in 10,000 years, but Antarctica would take considerably longer, since it is so much bigger.[9]
Education
Steffen attended ETH Zurich, from which he received a Doctor of Science degree in 1977 and a Diplom in 1983.[10]
Career
Steffen was an associate professor of geography at the University of Colorado Boulder from 1991 to 1997, whereupon he became a full professor there.[10] He was a lead author of the "Observations: Cryosphere" chapter of the IPCC AR5, released in 2013.[11]
