Everything seems to be getting more polarized lately, and global warming is no different. Facts suggested by opposing sides don't seem to change anyone's mind. This subject is sold on emotion just as TV commercials, and politicians are sold to us as well. Our ego, and identity become intertwined with our opinions, and then too much is on the line to accept a different point of view. Just as happens in the Patch comment sections, it usually breaks down to personal attacks, and mudslinging.
So, why do you believe in global warming? The single most common answer I have received after breaking through all the barriers boils down to "because they say so." Is their anyone that can state anything beyond "because they say so"
If you don't believe in Manmade global warming, can you state why?

If anyone can, great. I am simply trying to learn more, and ask questions. I am not here to argue, and hurl insults. If your only method of communication is as described, do it somewhere else. If you want to give your opinion, ask questions, and learn, welcome
A LITTLE BACKGROUND OF GLOBAL WARMING (To the best of my knowledge)

Most of the theory is based on computer models. The models are complicated, but basically state that more C02 will cause warming, which will then cause more water vapor in the air which basically triples the original C02 effect. This is called the positive feedback loop.
Some things don't' make it to the front pages of global warming debate, such as orbital cycles ocean current cycles, and Sun cycles.
The recent history, ( last two thousand years) we have had a significant warming, called, "Medieval warm period", and a colder time called "The Little ice age". The pro, and con debate of the two periods are if they were hemispheric, or global.
In the long period, (millions of years) their have been severe ice ages, and warming. During these time a fairly close correlation of C02 rising and falling with global temperatures is agreed. But causation is reversed almost every time. That means that the rise in C02 came AFTER warming, not before, and by about 800 years on average.
Glaciers are shrinking, and have been doing so for 300 years
The seas are rising, but have been doing so for 12,000 years.
It has warmed a little, and has been doing so since coming out of the little ice age around 1750, a hundred years before the industrial revolution.
The computer models that state the C02 ...warming....then more water vapor feedback uses what is described as empirical evidence for the C02, but as yet I have never read, or had anyone able to point out where their is empirical evidence for the water vapor feedback. This is very critical.
If anyone wants I can provide links for any of the above.
