Board of Trustees Professor Seminar
Assessing and Predicting Effects of Global Warming at Earth's Poles
Ross Powell, Ph.D.
Department of Geology & Environmental Geosciences
Board of Trustees Professor
Distinguished Research Professor
Why should we care about global warming? Ninety-seven percent (97%) of all scientists conducting research on climate change have data to convince them that global warming is real; yet debate rages about this issue in the public and political arenas. Scientists consider this to be one of the foremost issues societies will need to cope with in the future, but taking action to mediate causes and potential problems remains a struggle. Evidence for warming is amplified at high latitudes but the effect is global. Extensive efforts are underway to both document and quantify current and predict future rates of change. Dr. Powell will discuss the relevance of this issue to us, and what current faculty and students are doing that adds to a long history of polar research at NIU.
Ross Powell joined NIU in 1980. His main research focuses on dynamics of glaciers and ice sheets and their interaction with the sea, and in unraveling past ice sheet and climate cycles to better predict future trends. Ross has spent 40 years researching in Alaska, Antarctica, Baffin Island, Chile and Svalbard. He has 130 scientific publications (including in Nature), presented 285 talks at scientific conferences and is on many national and international committees. Current research includes helping establish and lead a $30 million international geological drilling program in Antarctica (ANDRILL); co-leading a large multi-disciplinary study of areas under the Antarctic Ice Sheet both in a sub-ice lake and where the ice goes afloat into the ocean (WISSARD); drilling in southern Alaska; and monitoring ice-ocean changes in Svalbard, all with an aim of understanding interactions of climate, ice sheets and sea level. He has had a one-of-a-kind robotic submarine built for future research under Antarctic ice.
