All credible projections indicate that temperatures here will become increasingly warmer on average for the rest of this century, even if greenhouse gas emission rates are greatly reduced. However, climate is not the only factor to consider in predicting future ecological change in the Champlain Basin; how people influence the landscape will be at least as important. The goal of this report is to assess the patterns and ecological consequences of recent and future climatic change in the Champlain Basin, and to use that information to stimulate further research, informed planning, and adaptive management that can help residents of the watershed to maintain its diverse natural communities in a warmer future. The report focuses, in particular, on species and habitats of Lake Champlain and its associated shorelines, wetlands and tributaries.
