What a lot of people don't buy into is the human factor - anthropomorphism - that humans are responsible for global warming. Climate is cyclical and we are entering into a warming period along with geological instability which is cyclical too. There is even indications that our magnetic poles are in the process of switching which is cyclical too, possibly fueling the geological instability.

Sometimes, during these climate cycles which are driven by our sun, a dramatic decrease in sunspots can trigger something called a Maunder Minimum - literally a mini ice age. The last one occurred around 1645 and continuing to about 1715. It's a very interesting phenomena:

Sunspots are at a low and it is thought we might be entering a Minimum.
