I've been following the anthropogenic induced climate change scam for many years and I don't use talking points. Perhaps your views on "global warming" are further symptoms of your jumping to conclusions.
The point I made remains the same. How does one molecule trap and redirect enough heat to noticeably warm 2500 other molecules? While you made a clumsy effort at deriding my comment, you didn't offer anything to provide insight into it.
Whether it's part of someone's talking points or not, it is still a relevant point. Adding up all of the earth's greenhouse gases (manmade and natural) excluding water vapor, it only adds up to 0.04% (generously rounded off) of the entire atmosphere. Presented graphically, that ratio of GHGs to the rest of the atmosphere would look like this:
Of the GHGs (the red dot in the upper left corner), the gray section in the enlarged red region below is presumed to be contributed by human activity:
I can't say I feel all too guilty about that gray area.
You also stated:
"The earth's system is a balance. If you ever tilt a sensitive balance by .04% you see that it changes."
Every physical state in nature is a balance. Your phrasing with import to the earth's system almost smacks of gaia fanaticism. You infer that this balance is sensitive. If you know that it is sensitive, exactly how sensitive is it? What are the tolerances? If you can't answer that with any specificity, then you should not infer that this balance is especially sensitive. Such presumptions equate to baseless conjecture on your part.
Over half of that 0.04% of GHGs has been in the atmosphere for over a century, yet regardless of the slow but steady increase, GTAs have gone down as well as up even during periods where aerosols were not a cause of temperature decreases. To say that the atmosphere's meager amount of GHGs is the main contributor to warming must infer that, barring events of high levels of aerosols and global dimming and such, the GTA should always be increasing along with GHG levels. We know that this isn't true. So much for being a sensitive balance.
I could continue this discussion on other numerous points, but after reading your replies to other posts here, it becomes abundantly clear that your real argument is something along the lines of, whether climate change is factual or not, we conservatives ought to bring about our own Kyoto so the liberals don't beat us to the punch. If that's truly the case, that logic would be akin to saying that we should all slit our own throats so Islamofacsists won't do it first. At this rate, you entirely miss the point.
While the climate may be warming for a period, there is no sound proof to reason that (a) it will continue unabated, (b) that GHGs are mainly to blame, (c) that mankind is solely at fault and (d) that mankind can do anything meaningful about it. Doing "something" about it is a waste of time and would amount to reckless political posturing at enormous costs. The end result in reality would be that conservatives would get the blame for creating costly policies that would wreck the economy and do little to affect climate change. I don't think we need that in our historical record.
The climate change issue is merely a convenient vehicle for socialists to kick the West right in it's energy based heart. We don't see climate change protests in China where energy use is just as rampant and energy waste is worse. I believe that if the US were to suddenly change all energy consuming devices to use some magical zero-pollution, free energy system, the leftist wackos would attack that as well on some unfounded grounds until the US bowed to a socialist agenda. As I have posted on numerous forums over the years, the bulk of the "scientists" on the pro-GW side are rife with socialist causes and are deeply entangled with the like of Sierra Club, Greenpeace and similar groups and this influence runs from the Woods Hole Oceanographic Institute right on through into NOAA and NASA.
"Global warming" is a farce and a scam used by socialists to push their agenda. Don't drink the warm kool-aid.
