The recent observations of climate models and satellite indicate that the total amount of water in the atmosphere will increase at a rate of 7% per Kelvin of surface warming Climate experts have cast doubt on the conclusions of a new study predicting that a warmer world would lead to more rainfall - a contradiction of the prediction of most climate change models - which was based on just 20 years of data.
The observations shows that total atmospheric water and precipitation have increased at about the same rate over the past two decades. Where as the recent analysis of satellite observations does not support this prediction of a quiet response of precipitation to global warming.
According to climatologist Brian Soden of the University of Miami in Florida -
"The study is the first to question the accuracy of precipitation in current climate models. There are dozens of different climate models out there, and every single one of them predicts that precipitation will increase more slowly than this study suggests. Plus, they all get the historical record wrong. Improving these models could help climatologists better predict future storms,"
