CANTON — After two years of virtual events, Clarkson University Science Cafes will return in person this fall on Tuesday, Sept. 20 in Canton, and Wednesday, September 21 in Potsdam with Dinosaurs, Asteroids and Climate Change.

The dinosaur-killing asteroid hit the surface of the Earth about 66 million years ago and resulted in a cascade of natural disasters, including widespread wildfires, tsunami, an impact winter and a hypothesized period of sustained global warming.

Using stable isotopic signatures preserved in microscopic fish fossils, we were able to test the global warming hypothesis and provide the first empirical evidence of warming following the asteroid impact.

Join Associate Professor Page Quinton (Earth and Environmental Sciences, SUNY Potsdam) to learn about how geologists study past climates and how this information can be used to understand the causes and consequences of modern climate change.

The Canton events will be held Tuesdays at 7:15 p.m. in The Rushton Conference Room in the Best Western University Inn at 90 E. Main Street, Canton. The Potsdam events are held on Wednesdays at 7:15 p.m. in the Potsdam Civic Center Community Room at 2 Park St.

The Science Café is sponsored by Clarkson University School of Arts & Sciences.
