This animated model shows the predicted effects of glacial melting and changes in vegetation patterns in the Blackfoot-Jackson Glacier Basin of Glacier National Park, Montana. The scenario incorporated in the model consists of a predicted exponential rise in atmospheric CO2 concentrations, a 2xCO2 global warming scenario, with a concurrent warming of 2-3 degrees centigrade (4-5 degrees Fahrenheit) by the year 2050. In addition, it assumes that precipitation, primarily in the form of rain, will increase over the same time period about 10 percent. The animation is accompanied by a set of still images displaying intermediate steps used in the calculations of the ecological components, such as terrain characteristics, sun impact, soil moisture, and wind.
