Global Warming Affects Desert Climates

How does global warming affect desert climates?  
source: Tell Me Why June 2012
We know that our planet is undergoing major climate change and that the level of carbon dioxide in the atmosphere is rising significantly. This has a major effect on the climate of deserts became hotter since 1976.
Global warning is expected to induce an overall increase in rainfall. However, since regions in the high latitudes are expected to warm more than those in mid and low latitudes, there will be more rainfall in high latitude deserts and less in sub tropical ones. As a result, desert in the lower latitudes are expected to grow. A new study has found that, as deserts become hotter their soil releases nitrogen in these arid environments, scientists believe, will result in a loss of whatever plant life there is in deserts.
