As a degreed climatologist, I could really get down in the weeds on this and explain why it's all B.S.
But let's take a simpler approach. How long has Earth been here? Some say millions of years, which I personally do not believe. Others say tens of thousands of years. Nobody knows for certain. What we do know for certain is that worldwide temperature MEASUREMENTS, not assumptions from carbon dating, tree rings, and all that bologna, but actual measurements, using calibrated thermometers, has been going on for less than 150 years. Which means that we have a <1% sample size.
In 3rd grade, we all learned that you cannot use a less than 1% sample size to describe the whole. That's bad science and leads to bad information.
Furthermore scientific law states matter cannot be created nor destroyed. In other words, we can transform one thing into another (trees into lumber, oar into steel, herbs into medicines, etc.) but we can't create new things and we can't destroy what God has made. It's science. Therefore, humans cannot "destroy the planet" by simply living here.
Also of interest, every time the local TV meteorologist says "we set a new record high today", I find it amusing that the old record we broke was set in the 1800s or early 1900s, long before there were cars, hairspray cans, and interstate highways everywhere. It was just as hot back then as it is now.
As the old saying goes, "there is nothing new under the sun".
