What I can say for certain is that CO2 is not a cause of global warming.
Al Gore proves this in the movie he starred in, An Inconvenient Truth.

The entire UN sponsored "find global warming" project was a scientific fiasco. It was a political project to get people to buy into carbon tax credits, so that people could be taxed more. Proponents of global warming will stay say 100s of scientist proved global warming, ignoring the fact that it was proven that 100s of UN scientists lied. (And they still will not release the model they used for their statements, saying, "Why should I give away decades of my research?")

We have also entered a new area of space. Astronomers have noted it being so. This information seems to be burried; nothing to see here, move along.

So, in the end, we have two active groups.

1. a group of people that care about the earth. But not really. Not if cuts into their life styles. And big corporations that are still polluting places out of sight aren't even talked about.

2. a group of politicians that want more taxes. This group is active and well funded. They hire writers and bloggers and internet trolls. They feed the MSM "news" reports. And they will never stop pushing for more taxes. They also seem to have a bottomless wallet from which to pay for their shenanigans.
