The Ecological Question

How might global temperature change during the 21st century?  How might these changes vary geographically, seasonally, and depending upon future human activities?


Students consider how to detect trends in large data sets against a background of variation. They use output from global climate models to examine projected climate change during the 21st century under a range of greenhouse gas emissions scenarios. Using Excel, they graph projected changes in temperature at particular locations over time and perform linear regressions. They compare projections of temperature change among emissions scenarios, across latitudinal gradients and between seasons. These exercises are adaptable to studying a wide range of climate parameters at any terrestrial location.
