Climate change semi-arid areas gridded climate data It is now recognized that global warming part of the climate change phenomenon is due to sharp increases in the concentration of greenhouse gases GHG such as carbon dioxide CO 2 methane CH 4 nitrous oxides N 2 O chlorofluorocarbons CFCs beyond their natural levels.

In many cities and towns in the arid and semi-arid West impervious cover and engineered conveyance systems reduce the amount of precipitation that enters the groundwater store. The hotter climate will mean more rain and the region will witness a 11 to 14 rise in average rainfall. Evaluation of responses of arid environments to global climate change requires further data collection experimental work modelling and interdisciplinary.

Both observa- tion and modelling studies have indicated that an aridity trend is occurring and will occur most significantly in the semi-arid regions in terms of precipitation soil moisture and. That global warming will likely enhance the agricultural potential of the arid zones turning them into a sort of greenhouse paradise. Download Full PDF Package.
