22 October 2015, Science Daily, Measuring the impacts of severe wildfires in the Arctic. Based on the number of acres burned, 2015 is shaping up to be the second most extreme fire year during the past decade in North America’s boreal region. Historically, the area has had one or fewer extreme fire years per decade. This season, 15 million acres burned in Alaska and Canada, according Northern Arizona University’s Michelle Mack, researcher and biological sciences professor, who is leading a NASA-funded project to measure the severe fire impacts in North America. “In the boreal region, there is a thick organic layer on the surface comprised of litter and soil, that in some cases is hundreds to thousands of years old,” Mack said. “Will more fires and hotter fires burn that layer and release it to the atmosphere and how deep will it burn into the soil?” These questions are part of NASA’s $100 million dollar, 10 year project called Arctic Boreal Vulnerability Experiment, also known as ABoVE. The experiment seeks to understand the vulnerability and resilience in the Arctic, where climate change is most pronounced and rapidly unfolding. Mack serves on the project’s international science team tasked with implementing the field campaign. Read More here
