My research focuses on how natural (forest fire) and anthropogenic (logging/ clear cut) disturbances affect the boreal forest and the feedback of boreal forest from a climate change perspective. I am collecting data on a number of climatic variables over the last four years to understand the mechanism. It will help us to manage the boreal forest more sustainably from a climate change perspective.
Abstract: We report measurements and analysis of a boreal forest fire, integrating the effects of greenhouse gases, aerosols, black carbon deposition on snow and sea ice, and postfire changes in surface albedo. The net effect of all agents was to increase radiative forcing during the first year (34 +/- 31 Watts per square meter of burned area), but to decrease radiative forcing when averaged over an 80-year fire cycle (-2.3 +/- 2.2 Watts per square meter) because multidecadal increases in surface albedo had a larger impact than fire-emitted greenhouse gases. This result implies that future increases in boreal fire may not accelerate climate warming.
