In an August 30th press release, the Intergovernmental Panel of Climate Change promised to address the relationship between climate change and water supply in more detail.
The IPCC says that the sustainability of water resources is a serious issue.
Dr. Pachauri says that a major challenge for scientists is whether catastrophic droughts and floods are changing.
On a global scale, pollution from certain regions - in particular soot from local sources - could affect local, regional, and larger scale weather according to the IPCC.
Global warming, increasing populations, and urbal sprawl are some of the reasons for water shortages.
Some regions have already felt the 'draught' of this problem such as sub-Saharan Africa. But water shortages will not only affect poorer areas according to a 2006 BBC News story (http://news.bbc.co.uk/2/hi/science/nature/4796909.stm). A report released that year by the WWF (a global environmental conservative organization) wealthier countries continue to waste water while using the water of developing countries. The report also said that it is up to wealthier countries to use their money and resources to preserve fresh water supplies.
