I just love how CO2 is classified as a "problem" period. Carbon is the fundamental building block of life on this planet and no amount of the failures' rewriting history and science will ever change that.
The only CO2 "problem" is the fraudsters are still exhaling it....
So, is that really the best you've got?
If water starts pouring under your front door, the fact that you'd die without it doesn't prevent it's presence a foot deep on your living room floor from being "a problem".
The purpose for this set of notes was to demonstrate AGW without invoking a computer model that all you deniers seem to think are the work of demons.
If you have some objective, technically supportable disagreement with any of the six point Dr Schmidt makes, let's hear 'em. "Carbon is the building block of life" wouldn't sell a six year old.
The amount of CO2 on this planet is the exact same as existed for the last 4 billion years or so. Very little has been added from extra planetary sources so CO2 is merely being used and reused in an endless cycle. If the atmospheric level of CO2 drops to 200ppm or less nothing grows and we all starve. That's a fact.
I don't care to "argue" with Schmidt because he's not capable of arguing a point. He is merely capable of talking at people. If they have differing opinions he prevent them from being published. In other words he's a scientific fraud. I don't waste my time with frauds.
