Well, Matt says ...
And of course, you argue that "we" haven't done that. Well, we have contributed, but you're correct fundamentally.
The problem with using percentage numbers is that they do not reflect the true scale of things. The figure of 35% also doesn't indicate a time range.
We generally talk about global warming since 1980, when global temperatures were just about at the mean value, as calculated by our esteemed climatologists.
Since 1980, atmospheric carbon dioxide content has increased ~ 14.7%.
Still, that seems like a big deal!
However, what it really means is a 50 PPM increase in atmospheric C02, from ~ 334 PPM to ~385 PPM.
That really means that C02 has risen from it's 1980 level of .033% of the atmopshere to it's current level of .039%.
These are both really small numbers.
In fact, C02 is a minimal part of the Earth's atmosphere, very minimal, and has little appreciable effect on greenhouse effect at these levels, especially when water vapor is a much more potent, and in fact THE primary greenhouse gas in the Earth's atmosphere.
Relative to the atmosphere, C02 has actually only increased over the past 27 years by 5/1000%.
As as to temperature, it is true we've observed an increase in "global mean temperature" since 1980 of (at its peak) ~ 0.5 degrees C (0.9 degrees F). However, that entire increase...which has been on a mild downswing since 2004, has been essentially wiped out in 2007, as we dropped 0.4 degrees C in one year. We are now at 1940 temperature levels. 1940 temperature levels were just a hair above the mean temperature (~0.5 degrees above the mean).
The fact is, the entire past 27 years of global warming, the topic of so much hysteria, has been eliminated.
You have to wonder what this is all about, and question why the increase in global temperature between 1910 and 1940, when there was a heck of alot less C02 being emmitted by humans, isn't mentioned at all....it increased during that period by over a half degree, at about the same rate that it had been increasing from 1980 to the present. And why did it drop between 1880 and 1910 by 0.4 degrees? And what about that 0.25 degree drop between 1940 and 1950, and the "massive" drop of 0.3 degrees in just a year in the latter 1970s, which of course signalled the impending Ice Age that never happened?
The fact is, we are sitting just about at mean global temperature values as we speak. There IS NO TEMPERATURE ANOMALY at the present time.
How much do you want to bet that you'll never see a chart that clearly shows what 2007 revealed? Or, how much do you want to bet that Al Gore will never acknowledge the fact that his ideas have just been eliminated, for the time being (one would've thought that the abject failure of "Live Earth" (Jesus...) would've sent him packing, but apparently not).
What we're looking at in this global warming data is a microcosm of a 12000 year old warming trend. We see the irregularities in what--observed in relation to the 12000 year scale of the real warming trend--is a tiny blip, and we make all sorts of conclusions about it that are essentially meritless.
..makes for an interesting hypothesis, but that's all it is.
We seem to neglect the actual facts in this matter, and prefer to think that we humans can actually effect the GLOBAL CLIMATE.
Mt. St. Helens, as we all know, erupted magnificently in 1980, and when it did it spewed more greenhouse gasses and pollutants into the atmophere in oine 24 hour period than all the automobiles in the United States at the time could've spewed in a decade.
Yet, the clear truth of the matter is that the Earth didn't care, and it cleansed itself of this actually minor annoyance ( a mere pimple on its surface...one of many that have occurred in documented history) rapidly.
Man has demonstrated no tangible or empirically demonstrated effect on the global climate. In fact, measuring something like average temperature globally is highly elusive, if not impossible to any great accuracy.
We know that the planet has apparently been warming for millennia. We also know that if history, which is documented many times over the past 700,000 years or so, repeats itself (which it certainly is wont to do), we will in a few centuies most probably, be cooling again, and that historians, as they do today regarding the nonsensical global ice age predictions of the latter 1970s, will chcukle at today's prediction of doom from something mankind has absolutely no effect upon, nor, despite his advanced sense of self-importance, could possibly have an effect on.
There's a reason for the short term cyclical temperature variants that we've seen since we've been able to accurately observe in detail. The man-made global warming nuts tend to ignore this, but the fact is that the engine that powers this planet is cyclical itself. It ebbs and flows in fairly regular rhythm, and it powers the global climate, and whatever temperature changes we see.
That's that bright light we see virtually every day in our skies: the Sun. The most logical, and certainly most plausible cause for what we can observe.
It's power is greater than the Earth's, and the Earth's power makes man look like a microscopic bacteria on its surface, which he in fact is.
No politically motivated nonsense concept will ever equal the real power that drives this planet.

That is what I said increased radiation.
