Ask A Scientist: Cores, Caves, and Climate Predictions

April 1st & 2nd, 2008

What is a paleoclimatologist? Tom Johnson, who is one, wants to take you through layers of climate history to decipher how rising concentrations of greenhouse gases affect Earth's patterns. Discover how scientists like Johnson, a professor with the University of Minnesota Duluth's Large Lakes Observatory and Department of Geological Sciences, use tree rings, marine sediments and coral, ice cores, and cave deposits to go "back to the future." Read a story about Johnson's talk.

The discussions, hosted by Minnesota Sea Grant, will take place on:

Tuesday, April 1, 6:30 – 7:30 p.m.
Blue Water Café
20 W. Wisconsin St., Grand Marais, Minn.
Wednesday, April 2, 7:00 – 8:00 p.m.
Amazing Grace Bakery and Café
394 S. Lake Ave., Canal Park, Duluth, Minn.
