This is just my opinion and it does not follow the preferred group think.
The sun spot activity has been dormant for the past 12 years. La Nina has been active for the last seven or so years. (NASA data) (Sunspot activity is thought to expand the upper atmosphere, affecting the weather and winds)
In fact, several years ago there were NO sunspots for the entire year. last year the sun had major sunspot eruptions, and even a few weeks ago it was very active. La Nina has completely broken down in the east pacific. (Howard's weather discussion for eastern Sierra)
We have been seeing the return to the normal fall flash floods in Vegas and New Mexico; haven't seen those for nearly a decade, but before then was not unusual. Europe usually goes through a severe drought every few years in the fall; hasn't happened in a few years (decade?) until this year. I could go on. but those of us who remember the "normal " weather of the 70, 80 and 90, remember this is now getting back to normal.
Just my humble opinion.
Lastly, they dont call it mother nature for nothing; just when you think you got it figured out.....
