Global warming causes lessmore precipitation

A paper published today in Nature Geoscience claims global warming caused a decrease in mountain rain & snow in the Northwest US that was somehow missed by satellite observations. 

This seems odd given given that the winter Northern Hemisphere snow extent has increased since 1967, as well as the global warming meme that warming causes increased water vapor and extreme precipitation.

Despite reports of no trends in snow- and rainfall, rivers in the northwest USA have run lower and lower in recent decades. A closer look at high- and low-altitude precipitation suggests that observational networks have missed a decline in mountain rain and snow that can explain the discrepancy.
