Geo.me Solutions has created a fairly in-depth mapped display of global climate data. The map is a Google Map containing placemarks that when opened reveal current weather data as well as historical weather data. In some cases there is data dating back three hundred years. The data is recorded from more than 1,500 weather stations around the globe. You can browse through the data sets by clicking on placemarks on the map or you can enter a search for a specific location.

Applications for Education
This map could be very useful for having students conduct their own analysis of climate trends around the world.
