|IS GLOBAL PRECIPITATION INCREASING?15-01-2016 10:17|
|Does anyone have any reliable info that shows whether global rainfall is increasing or decreasing?|
The two sites that I have posted seem to show that world precipitation is decreasing if anything. Am I missing something?

There is no global precipitation data. It's not possible to tell whether precipitation has changed worldwide.
The U.S. maintains weather stations scattered across the lower 48 that contain data back to 1890. These contain precip data that far back. The central NOAA site does not use weather station data (for reasons of their own).
This data shows that precip patterns across the U.S. has not changed outside of normal variation since 1890.
You can look at this data at http://cdiac.ornl.gov/epubs/ndp/ushcn/ushcn_map_interface.html

|It could be, because warmer air would be able to hold more moisture. This could result in higher precipitation totals.|
