Climate models and satellite observations both indicate the total amount of water in the atmosphere will increase substantially due to global warming at a rate of 7% K-1. However, the climate models predict global precipitation will increase at a much slower rate of 1-3% K-1. A recent analysis of satellite observations does not support this prediction of a muted response of precipitation to global warming. Rather, the observations suggest that precipitation and total atmospheric water have increased at about the same rate over the last two decades.
