Explain this, Al Gore!!

Okay, so Al Gore is a champion for global warming. His claims that the world is pretty much slowly melting from the effects of global warming have scared a lot of people.

So, if global warming were detrimental to our society, please explain to me why the majority of July had below-average temperatures. Why are the leaves changing on the trees already, and it’s only the first week of August? Why did the last winter end up so bitterly cold?
