Those aren't sources.

>“Researchers who study the Earth's climate create models to test their assumptions about the causes and trajectory of global warming. Around the world there are 28 or so research groups in more than a dozen countries who have written 61 climate models. Each takes a slightly different approach to the elements of the climate system, such as ice, oceans, or atmospheric chemistry.

This isn't a source. You need to provide the actual studies, and point out where it proves that global warming is caused by co2, and have a coherent argument. Right now seem to be throwing everything but the kitchen sink at me in an attempt to win the argument.

> The computer model that generated the results for this graphic is called "ModelE2," and was created by NASA's Goddard Institute for Space Studies (GISS), which has been a leader in climate projections for a generation. ModelE2 contains something on the order of 500,000 lines of code, and is run on a supercomputer at the NASA Center for Climate Simulation in Greenbelt, Maryland.”

500,000 lines of code? Oh wow, then, must be accurate! NASA did it, must be correct, right? That's how you prove things, you get NASA to sign off on them.

> The link is the summary of what calculating which physical formulas gives, as I've quoted. It's you who "doubt" in the "tree rings" and I've given you the context: tree rings are just a small piece of he whole picture, and what we know, including the levels of confidence from that part of science is still good enough to have a good picture of what is happening and what has happened before. But once again: not any single historical proxy is directly used when the physical formulas are applied.

When did I ever say I doubted tree rings? All I'm saying is that I'm not sure that co2 is a significant cause of global warming.

> > In the same spirit as your link, here is Leonard Nimoy talking about Global Cooling

> That's a joke, right? I'm presenting you the results of the NASA's best computer models, and you are giving me a link to... what actually? Since when are TV shows a proof for anything?

Actually, you're right, it was a joke, but you missed the punchline. You give me a link of a news reporter trying to interpret and regurgitate what scientists say now, and I give you an actor doing the same for what scientists said in the 1970's. You don't see the similarities?

> If you don't understand physics, I can imagine that it's hard to you to believe in something you simply don't understand, and I don't know your background to help you.

I do understand some physics. And what I don't I'm willing to learn. Do you? Why is it that all you do is regurgitate quotes from websites, or give arguments of authority?

> It's about the formulas and measurements. Note: I'm not saying "take that guy as a reference." I'm saying: he's the guy who didn't know enough but was willing to learn and made enough notes, so if you are actually interested in some formulas "for beginners" you can find them there. If you'd want something even "more serious"... you'd need at last university level material, which of course exists too...

You still haven't addressed my concerns the lack of transparency of your link from skepticalscience.com. You also didn't address the graph from co2levels.org. I was hoping you knew or would be able to say why temperature increase precedes co2 rising in the graph from co2levels.org. I was hoping you'd be able to show the sun output, the glaciation, the co2 levels against temperature, so I can see the relationship between them. At this point, though, it seems you're not interested.

I thought I was talking to someone who knew what they were saying. You're telling me to read this guys entire website, but I know all I'll be left with a bunch of conflicting data and further questions, and probably still not have my questions answered.

The reason I was talking to you in the first place was that I thought you had some understanding. But by now, I'm pretty convinced, you don't.

Believe it or not, I'm on the fence about whether co2 is the primary cause of global warming or not. I simply was refuting the original poster's assertion that co2 being the primary cause of warming was basic physics and the relationship is undeniable. Talking to you, it seems that you don't know much about the topic, but instead believe that arguments from authority are good enough. You can't find information that directly answers my questions, but instead point to just reams and reams of data that has nothing to do with what I asked, along with snide comments (ex. me "doubting tree rings", although I never brought this up).

I'm on the side of "Question authority" and you seem to be on the side of "Accept authority". That's fine, but I'm not interested in taking conclusions as gospel simply because NASA says so, no matter how many models nor lines of code were used.
