"Global Warming" or "Interesting Debate On Munk"

[Geminex]

I'm guessing the rest of the world is absolute in their stance, because they perceive it as an urgent matter of survival, which it quite possibly is. And your argument that "we can't know" is... interesting.

But see, I really can't think of any way that CO2 could have gotten into the air other than by human influence. There aren't all that huge amounts of free CO2 in depots or reservoirs. I doubt that it came from the earth itself. Definitely not volcanoes, we're doing quite a lot of monitoring there, and we probably would've noticed that. Besides, Unless it's extremely active, no volcano could come even close to the amount of gasses we put into the air.
I'm not definite. But I can say that there's a very high probability that the source of CO2 and other greenhouse gasses appears to be humanity. Also cows, but they're just there to feed the humans.

As for this:

But that's only the data for that one spot on Earth.

I guess that's an argument you could make. Though it does sound rather desperate. Yes, climate is a hugely complex business, and we can't even predict the weather with exactitude, let along analyze the exact impact of certain atmospheric gasses. But the physics behind global warming really aren't that complex. Solar radiation gets bounced back to earth when it tries to leave the atmosphere. Of course there's factors we don't know about, that we can't predict, that might even change the final outcome. But we really need to look at "what is most likely?" here, and not take a stance that amounts to "unless we can be 120% sure, the status quo remains".
