Well even though.... I will have a go.
Global warming models do agree. It is the regional models that have wide discrepancies.
Just like you can more accurately predict the result of 100 pennies landing face up as opposed to one penny. So to can you more accurately predict the sum of all atmospheric factors as opposed to what only a few environmental factors produce.
We are "recovering" from a cooling period. Fluctiations in earths orbit around the sun are on a 100,000 year cycle. The cycle we started on 6000 years ago tells us we should be cooling off, because we are getting farther and farther away from the sun as this part of the cycle progresses. And we were cooling off, up until the industrial revolution.
Natural fluctuations are static at 100,000 years long, proving that model is correct.
Finally physics proves global warming to be correct.
Carbon in the carbon dioxide and methane have a very specific heat capacity. Carbon is the reason life is on this planet. Without the warming effect of carbon in our atmosphere this planet would be a steady 32 degrees farenheit. Too cold for anything. We know from measurements that we have increased the atmospheres carbon content by 30% in the last 300 years. And this increase can be directly traced back to human sources. Basic physics and chemistry just shout it out to you that the carbon we are putting into the atmosphere is warming the planet.
