It is very easy to debunk the claim that it is “scientific fact” that man is causing “global warming”. All that is required is to refer to the following fundamental principle of science -
“ONLY EXPERIMENTAL DATA HAS THE POWER TO SHOW CAUSE.”
This is the basis of the scientific method and is not debatable.
Note that climatologists have NO EXPERIMENTAL DATA and will not have any anytime soon. Without experimental data, no reasonable conclusion can be obtained.
In order to produce experimental data on the concentration of CO2 in the atmosphere, the experiment would have to be performed at the same scale as the Earth’s atmosphere! Obviously that’s not going to happen.
Global Warming proponents have only observational data. A corollary to the above states:
“OBSERVATIONAL DATA CAN NEVER BE USED TO SHOW CAUSE, ONLY ASSOCIATION.”
I wonder how many “global warming” advocates know the difference between “cause” and “association”? The difference is of course vast.
As a scientist I have examined the theories and methods used by global warming proponents. It is nothing short of appalling to see their “scientific work”.
The principles which you rightly reassert apply equally to all sides of this debate, and certainty is thus equally suspect whether expressed by proponents or by deniers.
