California doesn’t need a global carbon-emissions regime; it needs a better water system.
That California’s catastrophic drought is a result of global warming has become a commonplace of contemporary political rhetoric. That truism isn’t true: Most scientific accounts of California’s current dry spell link recent low precipitation to naturally occurring atmospheric cycles, not to global warming. Indeed, most of the global-warming models relied upon by those advocating more-invasive environmental policies predict that warming would leave California with wetter winters — winter precipitation being critical to the snowpack-dependent state — rather than the drier winters at the root of the state’s current water crisis. What some studies do suggest is that warmer temperatures make the effects of scanty precipitation more intense for California’s end users of water, a reasonably straightforward proposition — higher temperatures will probably contribute to higher demand for water and will certainly contribute to the much more significant problem of evaporation, which steals tremendous amounts of water away from California’s outdated storage-and-conveyance infrastructure and imposes substantial water losses on old-fashioned irrigation systems.
