Climate Change: How do we know?
February 20, 2020 @ 6:30 pm - 8:00 pm
How do we know that Earth’s climate is changing? How do current trends fit into longer-term, natural cycles of climate change? How will changes in global climate impact us here in Maine? Join us for an informative presentation on establishing the evidence for present-day climate change, and placing it in the context of past climate changes by Dr. Bess Koffman, an Assistant Professor of Geology at Colby College. We’ll meet at the Camden Public Library, 55 Main St., Camden, on Thursday, February 20 at 6:30 pm.
Dr. Koffman has studied past changes in the Earth’s climate system using a combination of field and laboratory approaches. She is a paleoclimate scientist with twelve years’ experience working in the field of ice core paleoclimatology. She will speak about her research using ice cores from Antarctica and Alaska to study Earth’s climate. Dr. Koffman’s research is focused on learning about past changes in Earth’s atmospheric circulation, or winds. She uses mineral dust as a tracer of past wind patterns.
