Koppen Geiger Climate Shifts Mapped On-line

As a geographer religion, I have always been partial to the Von-Koppen climate classification schemes, and this map service from ESRI was a pleasure for me to see, because I wanted to do something like this as a grad-school project (a long, long time ago), but the technology just wasn't there. The authors have taken historical and modeled climate data, mapped it in the modified Koppen-Geiger system, and put it in an on-line map service hosted by ESRI. Make sure to press the little time slider to watch the decades slip by, and what the models portend for the future. - HLG http://www.arcgis.com/home/webmap/viewer.html?webmap=0b9f1f90f4f745daacbc35599609b59a
