 Abstract Simulations of future regional and global vegetation distributions and results from experiments on individual plants indicate that climate change is expected to alter significantly the functioning and distribution of major vegetation types. However, there is a significant disagreement in magnitude, directions and characteristics of these changes. Using a probabilistic approach we evaluate ecological risks of possible changes in the potential vegetation distribution over North America under different climate change scenarios. Currently we are exploring different approaches to characterization and visualization of uncertainty in the vegetation responses.
