Future: World

Below, 2071-2099 Average, Less 1971-2000 Average - for 2 RCPs
     from US National Climate Assessment

     Areas toward the poles get wetter, as water and ice there warm, increasing evaporation.

(Cross-hatching below means high agreement among the models used.)

Future: US

Observed US precipitation is from the draft 2013 US National Climate Assessment.

% change for 1991-2011 average, compared to 1901-60 average

     Below are observed changes in the amount of precipitation falling in very heavy events (the heaviest 1% of all daily events) from 1958 to 2011 for each region.

The 4 seasonal maps just below are for a high emissions case.
The 4 farther below are for a low emissions case.
