The FACT is there really isnt any viable evidence that global warming isnt real, that it isnt caused by human activities, and that it isnt going to cause REAL problems...

The fact is the global warming has been occuring for about 10,000 years, in this time frame, ocean levels have risen around 100 meters, and during this time frame there has been a period in which global temperature have been higher than current levels, and at this time there was no human industries or cars and human population was significantly lower than today by factor of 10 to 100. And global warming is not caused by humans because there were periods of global warming prior to the existance of humans.
CO2 is a trace gas in our atmosphere; CO2 is a greenhouse gas and does add to the greenhouse affect, but CO2 is not the primary cause of the greenhouse affect, water vapor is the major element causing Earth's greenhouse affect.
It is inaccurate to describe Earth's Climate as in a delicate balance which is so delicate that humans activity is or would significantly and/or permanently affect it. Earth's history is full of events which dwarf human activities; there common variety events, such as Hurriances, volcanos, forest fires, and flooding. Plus there are the rarer events such as large impactors and super volcanos.
The Sun is the whole ballgame, as far affecting Earth's climate, and idea that the heavens are serene and unchanging is completely wrong. Another big time player in global climate is the ocean, rather then the atmosphere. Other elements which could have a significant impact on Earth's climate.
There may be ways for human activity to significantly affect global climate, but changing the amount of CO2 in the Earth atmosphere would probably an inefficent way of doing this. In other words if global temperatures would to drop by say 2 C and we wanted to increase the temperature, increasing the amount CO2 in the atmosphere wouldn't be a effective way of doing this.
