Learning Objectives

25.2.1 Relate the observed increase in global temperature over the past century to the potential causes for the change in climate.

25.2.2 Describe the expected and observed responses of organisms' geographic distributions resulting from climate change.

25.2.3 Evaluate why current climate-community distribution relationships may not adequately predict the future composition of communities under climate change.

25.2.4 Determine the factors that may increase the susceptibility of species to extinction due to climate change.
