Simple question for you:
Does the climate ever "not change?"
Maybe should try another angle.
Global warming err global climate change err...what's next?
Climate change is non-sensical in light of the fact that the one constant throughout Earth is is of constant climate change.
The earth has been several degrees warmer and several degrees colder than it is on average now and humans had absolutely nothing to do with it. That's a fact.
Using your same logic, we could never convict anyone of murder, because people have been dying naturally for millennia.....
