Prove to me global warming is caused by man by proving the evidence I provided is flawed/incorrect

I am going to submit evidence that global warming may not be caused by man and most if not all of that evidence will summarily be dismissed do to non scientific reasons such as it is junk science or it is bought and paid for by some oil company, it is political propaganda by deniers or the scientists who are submitting the evidence have some ax to grind or they don't meet some higher learning qualification. I seriously doubt any of it will be analyzed or even compared to any evidence for global warming being caused by man. More than likely I will be sent to links justifying the pro position and none of my evidence will be addressed. Instead the focus will be shifted from my evidence and an attempt will be made to shift the burden of proof on me and I will have to prove their position. This will not happen in this debate. The burden of proof is on the challenger to prove why my evidence is invalid "SCIENTIFICALY", not politically or in any other manner that is not scientific. The sources I use are irrelevant, if it can be proved wrong with a high degree of conclusiveness using comparative scientific data from other sources it should be very easy for you to do. I will not dismiss your sources as I approach any evidence or theories on this subject as valid until I can compare the data and see if it is consistent, biased or completely incorrect based on other available data from both sides of the argument. If you are not willing to except the terms of this debate don't accept the challenge. If you attempt to dismiss any of my sources based on anything other than scientific reasons I will immediately end the debate because it will become a complete waste of my time. I am on this site to be educated on the subject both pro and con based on the scientific evidence from both sides of the argument. I do not care if I win or lose this debate. I am almost positive but not completely positive that when this debate is over nothing will be proved to any conclusive degree that man is more likely than not to be the cause of global warming based on the evidence available from both sides.
Being able to determine an average global temperature must be accurate in order to determine if the average global temperature is warming or cooling. Researchers in this link say it is thermodynamically and mathematically impossible to put a single number on the average temperature of the earth. Furthermore there are several different ways to figure averages and depending on which method you use you will get completely different results. So from this data it is impossible to tell if the average global temperature is rising without being biased towards one method of determining average global temperature. And if you do use a method that is biased you have to leave out the fact that it is mathematically and thermodynamically impossible to figure an average global temperature even when you use that biased method.

I have searched for other sources and could find none that dispute this claim. Good luck to you in your searches. You will find lots of sites claiming average temps but from the data I have read they are more likely than not to be flawed and inaccurate representations if indeed it is impossible to figure an average global temp. What I ask for in this link is a similar link that says it is not impossible to figure average global temps using mathematics and thermodynamics and that those figures are more likely to be accurate than not. This should be very easy to prove in my opinion because a great deal of the evidence for the pro side is based on the theory that average global temps are rising.

(GCM's ) General Circulation Models: They attempt to simulate or predict future climate conditions. These have been proven to be completely inaccurate and flawed at predicting climate changes in the future because the data that is initially input to generate the simulation is based on guesses and assumptions on how the climate works and scientists all agree that they are not even close to knowing how it works with any degree of accuracy. It is further stated that GCM's are unsuitable and to inaccurate for the basis of setting public policy with regard to Global warming

There are hundreds of links that discuss GCM's and virtually all of them admit to guessing or using arbitrary numbers based on the limited knowledge that is available on how the earth's climate works. My research indicates that GCM's are virtually worthless indicators of future global conditions.
!7,000 Scientists disagree that Co2 is the main cause of global warming and that we are still recovering from a small ice age and have provided an extensive report as to why they think this is so based on all available data with regard to the earth's climate. This report is extremely detailed and just as convincing as the pro side. Why is everything in this report not valid when used as evidence that would suggest global warming is not caused by man?

I want to know the truth about this subject. But for every link that says global warming is caused by man I can find one that is equally scientific if not more based on science that it isn't.
I wish my opponent luck, this will be a very hard for you because the burden of proof is on you should you accept this debate. Don't take this debate if you are not going to use science to prove my links wrong and make no attempt to shift the burden of proof on me. You are trying to convince me that global warming is caused by man by man. If you can prove that the evidence that I have provided is flawed or incorrect with a reasonable degree of conclusiveness I will change my mind.

I don't need to make a rebuttal under the terms of this debate as none of my evidence was addressed. The burden of proof is not on me.
