Co2 emissions have little effect on global warming and if the Un really wanted to cut down on Co2 emissions, they would go after oil and gas companies. But since they are on the payroll they don't go after them

I think global warming is a natural cycle anyway, and you might want to search a topic about CO2 production from sea water if it's assumed that we're as human is the only factor influencing greenhouse effect.
That's what I heard, too. The natural CO2 production is like 95% of the CO2 and man-made CO2 like 5% (don't remember the exact values). They also said that the earth already had warm and cold periods before mankind did exist. It was some scientific documentary where I saw this.
For the first point, it is true that only a small part of CO2 production is man-made (actually only about 3%) However, it is important to note that such a small amount represents massive emissions in absolute terms, and it can "tip the balance". Natural CO2 goes into the atmosphere is balanced by equal amounts of natural CO2 going out. That's how it always have been. This is not the same for man-made C02 production. There is no pre-designed way to absorb man-made CO2. An extra 3% going in not being compensated by 3% going out, and the balance is upset.
If you look at CO2 concentration in the atmosphere over a long period of time, you can see it rising sharply starting around 100-150 years ago and accelerating since. Concentration was more or less the same for thousands of years, but in the past century it has risen about 30%, starting exactly around the time one would expect it to be.
To tackle the second point regarding global warming mentioned by all three, it is also true that the Earth had fluctuating temperatures long before humans exist and such is the natural cycle of the planet. Climate aren't changed by humans alone, but this doesn't mean humans can't change the climate all by ourselves, and indeed at a greater speed than ever before. We know that the pace of warming is well out of proportions compared to any prehistoric warming periods. And of course, the earlier point of the big increase in CO2 concentration comes up also. The CO2 are not hanging around doing nothing.
