on drought becoming normal in the Southwest (davis):
Some climatologists have not hesitated to call this a "mega-drought," even the "worst in 500 years." Others have been more cautious, not yet sure whether the current aridity in the West has surpassed the notorious thresholds of the 1930s (the Dust Bowl in the southern Plains) or 1950s (devastating drought in the Southwest). But the debate is possibly beside the point: The most recent and authoritative research finds that the "evening redness in the West" (to invoke the portentous subtitle of Cormac McCarthy's Blood Meridian) is not simply episodic drought but the region's new "normal weather."
(...) Yet mere scientific pronouncement, even to the thunder of nineteen unanimous climate models, is unlikely to cause much of a flutter in golf-course suburbs of Phoenix, where luxury lifestyles consume 400 gallons of water per capita each day. Nor will it stop the bulldozers shaping monstrous strip suburbs of Las Vegas (a projected 160,000 new homes) along US 93 all the way to Kingman, Arizona. Nor, despite possible pumping out of the vast Ogallala Aquifer, the underground water resource lying under eight states in the Great Plains, will it prevent Texas from doubling its population by 2040.
(...) [technology eating itself up] More futuristically, there is also the "Saudi" option. Steve Erie, a University of California, San Diego, professor who has written extensively about water politics in Southern California, told me that desert developers in the Southwest and Baja California are confident that they can keep the population boom well-watered through the conversion of seawater. "The new mantra of the water agencies, of course, is incentivizing conservation and reclamation, but rapacious developers are casting covetous eyes at the Pacific Ocean and the alchemy of desalination heedless of the pernicious environmental consequences."
(...) [and who´ll bear the burden] As water becomes more expensive, the burden of adjustment to the new climatic and hydrological regime will fall on subaltern groups like farmworkers (jobs threatened by water transfers), the urban poor (who could easily see water charges soar by $100 to $200 per month), hardscrabble ranchers (including many Native Americans) and, especially, the imperiled rural populations of Northern Mexico. Indeed, the ending of the age of cheap water in the Southwest--especially as it may coincide with the end of cheap energy--will accentuate the region's already high levels of class and racial inequality as well as drive more emigrants to gamble with death in dangerous crossings of the border deserts. (It takes little imagination, moreover, to guess the Minutemen's future slogan: "They are coming to steal our water!")
(...) [and the future?] Conservative politics in Arizona and Texas will become even more envenomed and ethnically charged, if that is possible. The Southwest is already sown everywhere with violent nativism and what can only be described as proto-fascism: In the droughts to come, they may be the only seeds to germinate. As Jared Diamond points out in his recent bestseller Collapse, the ancient Anasazi did not succumb simply to drought but rather to the impact of unexpected aridity upon an over-exploited landscape inhabited by people little prepared to make sacrifices in their "expensive lifestyle." In the last instance, they preferred to eat one another.
