You are right, it is Global Warming.
Apparently, temperatures in the Pacific Ocean were 2 degrees warmer this summer (centigrade?). This has created an extremely strong El Nino event which has caused all this precipitation across North America. They really needed it in the West after several years of drought. Remember the big fires.
El Nino has no relationship whatsoever to the hoax known as “Golbal Warming.” - It is a normal cyclical pattern that has been less frequent in recent years due to the delay in the sun spot cycle.
