Dust Bowl 2.0

Brad Johnson on Texas population and climate:
One of the major reasons that there’s such a radical population shift is that central Texas is changing from arid grassland to uninhabitable desert, in part due to greenhouse pollution from the fossil fuels once buried under the ground. Other unsustainable practices, such as overpumping of groundwater, unregulated sprawl, and poor conservation practices are accelerating the desertification. The region has been in a drought since 1995-1996, with brief respites in 2007 and 2010 from catastrophic, flooding rains:
1996: “In Texas, losses to the agricultural industry exceeded $2.1 billion; statewide losses exceeded $5 billion.”
1998: “Without substantial rains, this year’s drought may be a worse disaster for Texas agriculture than the severe drought of 1996.”
2002: “Texas ranchers feel drought sting.”
2003: “Central Texas is in the midst of a seven-year drought.”
2005: “It’s been dry, it is dry, and it will likely stay dry through the winter, according to the state’s climatologist Dr. John Nielsen-Gammon based at Texas A&M University’s College of Geosciences.”
2006: “Texas’ drought losses have reached an estimated $4.1 billion, eclipsing the $2.1 billion mark set in 1998, according to Texas Cooperative Extension economists.”
2008: “Lack of rain and scorching temperatures hit Texas’ agricultural crops and beef operations hard late spring and summer, leading to an estimated $1.4 billion in drought losses, Texas AgriLife Extension Service economists reported.”
2009: “The most severe drought this part of Texas has ever seen means grazing pastures have dried up. Throughout central Texas, lake levels have fallen as much as 30 feet below normal, fields are cracking, and in some places half the cotton, corn and sorghum crops have withered away. Texas officials estimate losses are already at $3.6 billion and rising. . . . Over the past two months, Austin has sweltered through 19 days above 100 degrees. And rainfall is 20 inches below normal. ”
2011: “Deteriorating conditions in Texas and Oklahoma led to increased drought severity this week. In addition to the widespread wildfires in the region, impacts from agricultural areas are starting to be reported in counties along the Red River that illustrate the extreme nature of drought.”
This is just a taste of Texas’ future. “Triple-digit temperatures will be the norm in Texas within a few decades, and 115-degree heat won’t be surprising,” according to the state climatologist.
