It's most certainly the latter, California isn't designed to handle as high a load for the extreme hot weather. Growing cotton in Arizona is plain madness. This year, Arizona was hotter than Saudi Arabia during summer. Honestly, I don't see how the US can dig itself out of this one. The Chinese circumvented this problem by reducing the agrarian population significantly while acquiring massive land tracts in Africa for cultivation, but the US will be bound by the farming lobby. Perhaps government incentives to shift water utilization to newer technologies, instead of effectively subsidizing agriculture, might help.
