Researchers studying climate change have developed computer models to predict the possible change in global temperature and precipitation. The two most commonly used models are from the Hadley Centre for Climate Prediction and Research and the Canadian Centre for Climate Modeling and Analysis. For more information on these research centers and their climate models, please visit their websites.
Datasets are available from these centers that contains point data with an x and y location and variables for temperature and precipitation for the years 2020, 2050 and 2080. To view these data as a map we created grid cells and then created a series of thematic maps using the variables for the different years. For the Hadley Center Model the grid cell size is 3.75 degrees (long) x 2.5 degrees (lat). The grid dimensions for the Canadian Centre model are 3.75 (long) x 3.71 (lat). Temperature values are in degrees centigrade and precipitation is defined as percent change.
Below is a sampling of the maps created using the climate change models:
