Polar Diagrams of Potential Changes in Mean Centers
The links below allow you to explore potential changes in distance and direction of mean centers of suitable habitat for 147 bird species for the Hadley High (harsh scenario), PCM Low (mild scenario) and the GCM3-Avg. High and GCM3-Average Low (the average of all the three GCM scenarios for high and low carbon emissions).   Context-Sensitive Help    

Potential changes in distance and direction of mean centers of suitable habitat for 147 species, according to the Hadley A1f1 emission scenario. Note the 0-700 km scale on the spokes.

Mean Center Polar Graph - Hadley High

Potential changes in distance and direction of mean centers of suitable habitat for 147 species, according to the PCM B1 emission scenario. Note the 0-400 km scale on the spokes.

Mean Center Polar Graph - PCM Low

Potential changes in distance and direction of mean centers of suitable habitat for 147 species, according to the average high emission scenarios (PCM, Hadley, GFDL). Note the 0-700 km scale on the spokes.

Mean Center Polar Graph - GCM3-Avg High

Potential changes in distance and direction of mean centers of suitable habitat for 147 species, according to the average low emission scenarios (PCM, Hadley, GFDL). Note the 0-500 km scale on the spokes. Mean Center Polar Graph - GCM3-Avg Low
