How will climate change affect future water supply in United States?

Many scientists believe that the increased climate change impact will severely reduce future water supply and significantly increase the risk of future water shortages.

Why is global climate change such a threat to future water supply? This is mostly because it is expected that climate change will significantly decrease the amount of rainfall compared to today’s levels. Add to this the fact that world population in constantly growing and you have a future where water will indeed become the most precious resource on our planet that will sadly not be available for all to use.

And what about the possibility of future water shortages in the United States? According to the recent study published in the ACS's Journal of Environmental Science & Technology United States will also experience problems with water supply in years to come.

The results of this new study say that more than 1 in 3 counties in the United States could face a "high" or "extreme" risk of water shortages due to climate change by the year 2050.

The report also says that 7 in 10 of the more than 3,100 U.S. counties could face "some" risk of shortages of fresh water for drinking, farming and other uses.

The researchers have concluded this by developing so called "water supply sustainability risk index" that includes factors such as water withdrawal, expected population growth, susceptibility to drought, projected climate change and other factors in individual U.S. counties for the year 2050.

The U.S. counties that are likely to be worst affected by water shortages are in southern and southwestern states and in southern Great Plains states.

The sustainable use of water resources has already become one of main prerequisites for our future wellbeing.
