This map visualizes what climate change actually means in terms of precipitation changes in different parts of the globe over a 100-year period (from 1980/89 to 2080/99) under the greenhouse gas emission scenario A1b (see further). With respect to the global drylands, the following table summarizes these changes by relating Read more…

The general moisture regime of the drylands of the world can be expressed by a simple measure, the aridity index (ratio annual precipitation to annual potential evapotranspiration). The following classes are shown on this map: Hyper-arid: aridity index <0.03 Characterized by very low and irregular rain, which may fall in any Read more…
The drylands of the world show great diversity in their temperature characteristics and precipitation patterns. This map captures this diversity in a limited number of classes with the following characteristics: NON-TROPICAL DRYLANDS Cold (< 10° C) to mild winters (10-20° C); Mild (10-20° C) to very warm (> 30° C) Read more…
