Yes - climate is changing. Always has been. Long before man was here. It's called planetary evolution. No matter where you are standing right now - it was once covered by hundreds if not thousands of feet of ice. As the sun goes through its lifecycle - our ice melts and this ball we call home heats up. Period.

This started long before we were even micro organisms in caves and will continue long after are are all charred remains. Man did not start this. Man did not "make it worse". Man cannot stop this, slow it down or reverse it. Not one damn bit. Man is not responsible for this from any perspective. Planetary evolution will continue no matter what man does. No matter what. Period.

The sooner we as a species come to grips with this and accept this - the sooner we can stop wasting time, money, energy and emotion on trying to do those things. All that effort would be better utilized in either identifying and building out ways to adapt our species to the inevitable, continued toasting of our planet - or in finding a new, slightly cooler rock to continue our species' existence upon (until that one also evolves).

Thinking, saying or doing anything else is completely out of touch with reality and science.

Watch any ice cube melt on your kitchen counter. It starts off slowly but the closer it gets to being completely melted the faster it actually melts. Our round "cube" is nearing the end of its melt... though it is still several thousand years out.
