John Smol Canada Research Chair in Environmental Change and Professor, Department of Biology Synopsis: Dr. John Smol is world-renowned paleolimnologist (someone who studies long-term environmental change using lake sediments), and he has received over 60 awards for his research, outreach and teaching. He has conducted studies around the world on the impacts of humans on the environment, with a particular focus on the Arctic. In this episode, Dr. Smol describes how the study of paleolimnology allows humans to study the difference between natural and human changes to the environment. The changes in lakes are often “under the radar,” and Dr. Smol explains how these subtle changes are affecting fish populations and altering the ecology of lakes. Dr. Smol sees his duty as providing both scientific knowledge to public policy-makers and tools for science translation to the general public so that everyone can understand the science behind climate change.
