A scientist at the University of Minnesota may have found a better way to track the effects of climate change on Arctic and boreal regions like northern Minnesota where temperatures are rising at some of the fastest rates in the world. Rui Cheng, a professor in the Department of Bioproducts and Biosystems Engineering at the University of Minnesota, is behind the research on using leaf glow to monitor vegetation dynamics. While not visible under natural light, leaf glow can be detected using remote sensing and can provide important information about the health of Arctic-boreal ecosystems.Cheng shared more about the research on this week’s Climate Cast.
