Two global climate change experts to speak April 6

Lehigh’s Department of Earth and Environmental Sciences (EES) will present two lectures on Friday, April 6 as part of the department’s annual D. Foster Hewett Lecture Series.

Lonnie G. Thompson, Ph.D., University Distinguished Professor in the department of geological sciences and a senior research scientist of the Byrd Polar Research Center at Ohio State University, will deliver a talk titled “Abrupt Climate Change: Past, Present and Future” at 12:10 p.m. in Lewis Lab 270.

Michael E. Mann, Ph.D., associate professor of meteorology and geological sciences and director of Earth System Science Center at Pennsylvania State University will speak on “The Scientific Case for Climate Change and its Causation” at 1:10 p.m. in the same location.

Thompson is a world famous ice-core climate scientist, considered the founder of tropical alpine paleoclimatology. Over the last several decades, he has been collecting ice cores from some of the most imposing mountaintops of the world, including the Andes, the Himalayas and Mount Kilimanjaro in Africa.

He has become a celebrity in helping capture the public’s attention on rapidly shrinking tropical mountain top glaciers in the world. Thompson has received many international awards, including the Tyler Prize, the world prize for environmental achievement.

He was also selected in 2001 by Time magazine and CNN as one of America’s Best in Science and Medicine, and was elected member of The National Academy of Sciences in 2005.

Mann is a leading climatologist who attained public prominence as author of a number of ground-breaking articles on temperature reconstructions over the last 1000 years, using tree rings, ice core and sediments. This evidence suggested a recent sharp rise in temperature caused by human activities, referred to as the Hockey Stick curve. In fact, Scientific American magazine described him as the Man Behind the Hockey Stick.”

He was lead author of a chapter in the Intergovernmental Panel on Climate Change (IPCC) 2001 Assessment Report. He has been selected as one the 50 leading visionaries in Science and Technology by Scientific American.
