UM professor to speak on climate change

ORONO – Stephen Norton, University of Maine professor emeritus of Earth sciences, will present the second lecture in the UMaine Climate Change Institute’s monthly series, “Climate Change on Planet Earth.” The lecture is scheduled for 6:30 p.m. Wednesday, Dec. 10, at Bangor Public Library.

Norton, an internationally known geochemist, will discuss “Maine’s Air Pollution History: Distant Past to Near Future.” He will share how archival natural records help scientists reconstruct aspects of Maine’s chemical climate since deglaciation about 14,000 years ago, and how direct measurements enable people to understand what has happened over the last few decades and what could happen in the future.

The lecture series is intended to make the science of climate change accessible to a broad audience. All lectures are free and open to the public.
