      One of the things that is little commented on in the discussions about climate change is the loss of water catchments.  

      If we are going to transition to a warmer planet without ice caps, without glaciers, with much reduced winter snow cover, that makes for a lot less water when you want to go turn on the hose.  And as the previous post noted, when rain does come and in deluge form, it doesn't soak in and tends to run off. In the future, catchments will be needed to hold surface waters and recharge underground aquifers.  If we weren't so worried about fiscal cliffs, there could be a lot of civil engineering projects (and jobs!) being done.

      Another thing to think about is how our agriculture is dependent on shallow rooted annual plants that are not very drought tolerant.  All of the cereal grains are grasses that do best with regular watering.  The most drought tolerant one, millet, is also the one with the least research attention devoted to it.
