Simulating Global Warming: How Will Plant Communities Grow in Plus 2 Degrees? Field Notes on Climate Change

    • Natural Sciences

Global temperatures are rising. Whether our reduced carbon goals are met or not, we’re still likely to reach a 2oC rise. So how will our arctic plant communities grow and cope with these warmer conditions?By placing OTCs (open-top chambers best described as a small a plexiglass greenhouse with an open-top) on top of plots of natural Arctic plant growth above the tree line, which increase their internal temperature by 1-2oC, we can see what happens to the plant communities when given warmer seasons.If tree growth increases in the Arctic, the region will lose some of it’s large, white snow-cover, important for reflecting heat from the sun.In this episode, we cross Lake Tornetrask to establish these OTCs on a mountainside, then return to the Abisko Scientific Research Station to speak to Ellen Dorreppal, Senior Lecturer at Umea University, about her work. After listening, please consider taking part in a short listener survey. It'll take less than 10 minutes, all responses are anonymous and the data collected will form part of Emma Brisdion's MSc thesis.
