Major U.S. drought coming by 2021?

Drought conditions generally are not welcome anywhere these days. A lack of moisture makes for uneven crops and other agricultural conditions that raise food prices and create supply and demand imbalances -- and that's not good for producers or consumers.

Climate scientists said late last week that Texas may even face a future of consistent drought conditions as bad as the record dry years of the 1950s because of global warming. While there are supporters and foes of global warming, specific scientific data supports a rise in coming global temperatures, right?

Whatever your position on global warming, a trend towards a drier, hotter southwestern U.S. may be coming in the next 15 years and it's feared dust bowl-like conditions could re-emerge -- and not in temporary fashion.
