First off, you did not state that some specific observation was not evidence. You stated that no observations were evidence. That is what I was hoping you would explain.
When you tell us that you "believe" the temperature increase (or decrease) is caused by a minute change in an atmospheric trace element, it's on you to show us the evidence. That is, lab experiments that control for eliminating all variables save for minute changes in an atmospheric trace element.
There are thousands of lab results that show CO2 behaves precisely as it is universally understood to do - absorbs IR radiation in certain bands. Attempting to dispute that is simply assinine. That it behaves in the same manner in the atmosphere - and I assure you it's absorption tendencies have been tested at all ranges of pressure and temperature - and that it is responsible for a portion of the greenhouse warming we undergo, is supported by mountains of evidence. If you would like us to believe that for some reason it does NOT behave in the atmosphere as it has been found to do in the lab, YOU are the one who needs to provide additional evidence - additional observations. That its atmospheric increase is responsible for the concurrent global increase in temperature is supported by mountains of evidence most conveniently seen at WG-I, The Physical Science Basis of AR5 from the IPCC.
If you can't show us the lab work, what you're putting forth is an article of faith on your part.
You believe CO2 is the culprit, but you presented no evidence to back up your claim
What's actually needed is a better understanding on your part as to how science operates. Tell me, what lab work does one find in the field of astrophysics? Astronomy? Cosmology? Do you perhaps believe them not be sciences and unable to formulate or test hypotheses?
And, again, there is an ENORMOUS amount of evidence that CO2 absorbs IR as has been understood for quite some time. I know it would be handy for deniers if it did not, but, hey, if you didn't want a challenge, you wouldn't have chosen to reject a theory that has earned almost universal acceptance among the experts.
In your car analogy, the car was full of other passengers, other variables, but you're telling us you believe a minute changes in an atmospheric trace element was the shooter.
Car analogy? You mean the observing-a-murder analogy?
My belief that increased CO2 is the cause of our warming is not an act of faith. It is supported by mountains of EVIDENCE driving extremely robust science and that belief is shared by virtually every scientist and educated individual on the face of this planet.
Sorry, I've installed bidets in both my bathrooms. Just for fun, though, to what "residue test" do you refer?
