Scientists have found evidence that increased evaporation could result in more extreme weather as global warming progresses . The IPCC Third Annual Report says : " ... global average water vapor concentration and precipitation are projected to increase during the 21st century . By the second half of the 21st century , it is likely that precipitation will have increased over northern mid - to high latitudes and Antarctica in winter . At low latitudes there are both regional increases and decreases over land areas . Larger year-to-year variations in precipitation are very likely over most areas where an increase in mean precipitation is projected . " Research based on satellite observations , published in October 2010 , shows an increase in the flow of freshwater into the world 's oceans , partly from melting ice and partly from increased precipitation driven by an increase in global ocean evaporation . The increase in global freshwater flow , based on data from 1994 to 2006 , was about 18 % . Much of the increase is in areas which already experience high rainfall . One effect , as perhaps experienced in the 2010 Pakistan floods , is to overwhelm flood control infrastructure
