Global Drought on the Horizon?

According to a new study by the National Center for Atmospheric Research (NCAR), the United States and many other heavily populated countries could face a growing threat of severe and prolonged drought in coming decades, as a result of warming temperatures associated with climate change (notice how I didn't say global warming!). These warming temperatures will likely create increasingly dry conditions across much of the globe in the next 30 years, possibly reaching a scale in some regions by the end of the century that has rarely, if ever, been observed in modern times.

The study,
which is highlighted in an article in "Wiley Interdisciplinary Reviews: Climate Change," indicates that most at risk would be the Western Hemisphere, along with large parts of Eurasia, Africa, and Australia, while higher-latitude regions from Alaska to Scandinavia are likely to experience opposite conditions.

An expert working on the study noted that if the projections come even close to being realized, the consequences for society worldwide will be enormous as some of the worst impact we face will involve a decrease in water as a natural resource.
