CAMDEN — Climate scientist Paul Mayewski will lead a program titled “The Arctic, Maine, and the First Abrupt Climate Change Event of the Modern Era” in an online webinar for Merryspring Nature Center Tuesday, Sept. 7 at noon.

As the earth’s “first responder,” ice communicates to scientists the effects of a warming planet. In this program, internationally acclaimed glaciologist, climate scientist, and polar explorer, Dr. Paul Mayewski, will speak about his expeditions to observe arctic ice and how atmospheric emissions from human activity are affecting the Arctic at a rate two to three times more than the rest of the planet — including how what happens in the Arctic affects Maine.

Mayewski is the director of the multidisciplinary Climate Change Institute and distinguished professor in the School of Earth Sciences, School of Marine Sciences, School of Policy and International Affairs, Business School, and Law School at the University of Maine. He has led more than 60 expeditions to the remotest polar and high-elevation regions of the planet and has received many awards for his and his teams’ contributions to climate science. He has over 500 scientific publications, two books, and has made many media appearances in print and television.
