It is very telling how the AGW believers always come back to politics even while they say they believe in the science, not politics. Let's start from the beginning.
Is it warming? Maybe, maybe not.
There is no question about it. For the last 150 years, the world has been getting warmer. No one doubts that, even on your side of the argument.
For 4.5 billions years there has never been a time when the temperature of earth was static.
Human civilization hasn't been around for 4.5 billion years. We've been around for about 12,000. During that period, temperatures HAVE been quite stable. Civilization developed under those conditions. We have built an enormous infrastructure under those conditions. Now those conditions are changing and at an unnaturally rapid rate.
That is why the true believers went from global cooling in the 70s to global warming and now schucks, it's just climate change.
Meaningless nonsense. A minority of experts were concerned about possible cooling in the 1970s. They were never a majority and the majority of the experts even then were concerned about warming from human GHG emissions. Reviews of the literature showing precisely that have been posted here repeatedly. Global warming and climate change are different terms with different meanings. If that's what you've got as an argument, you've got nothing.
Is it greenhouse gases? Who knows. Certainly not the clowns that give us nothing but computer models that don't work.
Is what a greenhouse gas? CO2? That's been accepted science for well over a century and their were no computer models a century ago. The GCMs of today work far better than the misinformation you've apparently received and if you think assumptions of anthropogenic greenhouse warming make them inaccurate, try to remember that NO ONE has produced a functioning GCM that stays within miles of reality WITHOUT assuming anthropogenic global warming. No one.
Although here, one should treat this like any other experiment and do double blind experiments that eliminate other factors like, I don't know, the sun? Cloud cover? Ocean currents? Show me these, and many others, being eliminated through scientific experiments.
Show me another Earth to use as a control.
If greenhouse gases, is it CO2? Show me the double blind studies eliminating nitrogen, oxygen, argon and water among others. And at .04% of the atmosphere, why do you guys cling bitterly to CO2?
Why do you cling bitterly to such nonsense? The greenhouse warming from all the other constituents of the atmosphere have been heavily studied for over a century. For starters, nitrogen, oxygen and argon are not greenhouse gases, as has been amply demonstrated in numerous laboratory experiments. Water, of course, is one. The greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, ozone and the chlorofluorocarbon group. They exhibit the defining property of greenhouse gases: they absorb infrared radiation within the frequency band radiated by the Earth - a property easily tested in the lab. Despite what may seem the small proportion that CO2 makes up in the Earth's atmosphere, it has been well demonstrated to be capable of doing precisely that with which it is credited. The human emission of methane has also had a warming effect, though methane does not have the lifetime of CO2. Water vapor levels are controlled almost entirely by temperatures, so as the Earth's temperature rises, water vapor will enhance the warming effect our CO2 emissions produce. Water vapor has an atmospheric lifetime measured in single digits of days while CO2 will last 30-95 years. There is also the point that the final release of IR radiation to space takes place in the uppermost layers of the atmosphere, an area almost devoid of water vapor.
THAT is why scientists "cling bitterly" to CO2 as the primary causation of the global warming we've experienced over the last 150 years.
Yes.

And your still calling people deniers. Not too scientific. In fact, rather political.
It isn't the least bit political. You claimed that your observations showed we had nothing but political motivations for a belief in mainstream climate science, yet you showed not a single iota of evidence supporting that charge. What you did show was a abysmal weakness in science and a small collection of out-of-date denier memes.
I call people "deniers" when they deny an argument without valid cause. Mountains of evidence and the opinions of the vast majority of the experts tell us that the primary cause of the warming we've experience over the last 150 years has been the greenhouse effect acting on human GHG emissions and deforestation. If you deny that, I would call you a denier. Simple enough. And no politics involved.
