It's definitely happening... I'm not sure how "deniers" arrive at their conclusions. Of course, I find myself a little concerned that we are entering a "mini ice age" for the next 11 years... that'll give deniers fuel for their arguments... but what's happening (a natural cycle) is a bit like putting a few ice cubes in a pot that's heating on the stove... it may get cooler for a moment, but it remains a pot heating on the stove.

The interspecies thing is already happening... more and from "Grolar" bears sighted (grizzly/polar bear)...
