The science doesn't lie. I am just amazed at how many people are wrong with what is going on.

I think science can be wrong, but I'm not sure wy you think what you said is anything new.
Through study of sedimentary archives, it has become increasingly apparent that during much of the last 65 million years and beyond, Earth's climate system has experienced continuous change, drifting from extremes of expansive warmth with ice-free poles, to extremes of cold with massive continental ice-sheets and polar ice caps. Such change is not unexpected, because the primary forces that drive long-term climate, Earth's orbital geometry and plate tectonics, are also in perpetual motion. Much of the higher frequency change in climate (104 to 105 years) is generated by periodic and quasi-periodic oscillations in Earth's orbital parameters of eccentricity, obliquity, and precession that affect the distribution and amount of incident solar energy (Fig. 1) (1). Whereas eccentricity affects climate by modulating the amplitude of precession and thus influencing the total annual/seasonal solar energy budget, obliquity changes the latitudinal distribution of insolation. Because the orbital parameters vary with distinct tempos that remain stable for tens of millions of years (2), they provide a steady and, hence, predictable pacing of climate.

We already know that orbital variations result in large changes in climate, underpinning such things as ice-age cycles. OK. We know that.

You say that during these periods changes in CO2 are natural. Yeah, they are.
And?

Ask your geography dude whether CO2 is a GHG. Then ask him what GHGs do. Then put 2+2 together.

I honestly doubt that your average person knows about the orbital cycles of our planet and the earth. They are too busy believing one potential side of the global warming argument, the side that I believe has the least effect on our climate.
Co2 emmisions are natural and it seems you understand that. But what I don't think you're getting is that they can mean the difference between a few thousand or more years of sunny days on the beach or a couple hundred thousand years of ice skating on that same beach.
I don't have to ask my geography teacher about green house gases, I think by now everyone and their dog has heard the same story over a million times. We can't escape that one idea that the media, schools, politicians and whoever else can get their bit in have implemented in our minds.
I think that humans can help in speeding up the process and increasing the already exsting amount of GHG. We do effect our planet no doubt, but the question is, how much?

But current understanding suggests it will be enough to likely result in detrimental effects (i.e., climate sensitivity of 2-4'C).

A person who claims to get snow and uses that as an excuse against global warming is not armed enough to even be having this discussion.
Remember all the reports of blizzards in Colorado last January. Of course, who cares that is it snowing in Colorado? But they got excessive amounts of snow that was unusual for even them. And you can expect more stories like this to come out.
The fact is, if it were snowing in the Sonoran Desert right now, that is a sign of something seriously wrong.

Likely: means, well,.....we might be right, we might be wrong......your just going to have to wait to see if we are right....BUT in the mean time we would like you to pay these taxes we have decided will save the planet. We would also like you to start walking to work, to school to your friends house. By the way, we would also like you to join our collective. The collective is all those people that committed to saving the world, despite it not needing to be saved.
These are code words for global warming fanatics. Just keep making sure it sounds scary. Make them think it exists, therefore it does exist. Don;t stop kidding yourself...we need you to bring in more people to the collective!!!!!!
