Research Interests

Glen M Sproul dit MacDonald works on issues of climate change and ecological and societal responses. His lab uses a number of research tools to develop long temporal records of climatic and environmental change and large spatial records of such changes. These tools include biological, elemental geochemical and isotopic analysis of lake sediments and wetland sediments, tree-ring analysis, satellite remote sensing and modeling. Studies of treelines and climate change, drought and its impacts, vegetation and fire, dynamics and carbon stores of wetlands, and sea-level rise and coastal marshes have been particular foci of his research. Field sites have included Canada, the western USA, Russia, Mexico, Egypt, Syria and India. He often works with international teams of academic, government and NGO researchers. Glen believes in the public communication of science and writes and speaks frequently for more general audiences and policy makers. Glen has published over 160 scientific papers and is a Member of the National Academy of Science.
