I admit, I was convinced that global warming was happening. Droughts where I currently reside in Texas, little snow where I grew up in Minnesota, etc.
This winter, for some reason, I’m not so sure. 
Could it be that the warmth of the past few years has been more due to El Niño? Then again, you could ask, if it has been due a change in ocean currents, is that change still due to too much pollution in the air?
I’m no expert in all that, not a scientist, but it would make sense to me.
