Professor Emeritus Kenton Stewart’s legacy continues. Climate change has contributed to a loss of ice on northern lakes and ponds, and that has consequences for local ecosystems. In the 1980s, he needed volunteers to help collect data. For many years, Dr. Stewart used public-involved science to monitor a changing climate. His approach foreshadowed our current ‘big data’ world, collecting lake freezing and melting dates from the public.
