EPA admits global warming is a good thing: page 19 "The Administrator acknowledges that as for human health, so too for welfare: moderate temperature increases may have some benefits, particularly for agriculture and forestry over the short term, as summarized above in this section and discussed in more detail in the Technical Support Document in Part IV, sections 9(a) and 10(a). This possibility is not inconsistent with a judgment that greenhouse gases in the atmosphere endanger welfare. Beneficial effects can coexist with harmful effects, and it is not necessary to reach a firm conclusion, for particular domains and sectors, about the net result in order to reach an overall conclusion in favor of endangerment."
EPA also admits water vapor is the most abundant greenhouse gas, but would only consider regulations to prevent contrails!!!
"Water vapor may be an issue of concern when it is emitted by aircraft at high altitudes, where, under certain conditions, it can lead to the formation of condensation trails, referred to as contrails. Similar to high-altitude, thin clouds, contrails have a warming effect. Extensive cirrus clouds can also develop from aviation contrails, and increases in cirrus cloud cover would also have a warming effect. The IPCC Fourth Assessment Report estimated a very small positive heating effect for linear contrails, with a low degree of scientific understanding."

Yep!

THE ACQUITTAL OF CARBON DIOXIDE
by Jeffrey A. Glassman, PhD
ABSTRACT:
"Carbon dioxide in the atmosphere [historically] is the product of oceanic respiration due to the well-known but under-appreciated solubility pump. Carbon dioxide rises out of warm ocean waters where it is added to the atmosphere. There it is mixed with residual and accidental CO2, and circulated, to be absorbed into the sink of the cold ocean waters. Next the thermohaline circulation carries the CO2-rich sea water deep into the ocean. A millennium later it appears at the surface in warm waters, saturated by lower pressure and higher temperature, to be exhausted back into the atmosphere. Throughout the past 420 millennia, comprising four interglacial periods, the Vostok record of atmospheric carbon dioxide concentration is imprinted with, and fully characterized by, the physics of the solubility of CO2 in water, along with the lag in the deep ocean circulation.
Notwithstanding that carbon dioxide is a greenhouse gas, atmospheric carbon dioxide has neither caused nor amplified global temperature increases. Increased carbon dioxide has been an effect of global warming, not a cause. Technically, carbon dioxide is a lagging proxy for ocean temperatures. When global temperature, and along with it, ocean temperature rises, the physics of solubility causes atmospheric CO2 to increase.
If increases in carbon dioxide, or any other greenhouse gas, could have in turn raised global temperatures, the positive feedback would have been catastrophic. While the conditions for such a catastrophe were present in the Vostok record from natural causes, the runaway event did not occur. Carbon dioxide does not accumulate in the atmosphere."

The graph above represents temperature and CO2 levels over the past 400,000 years. It is the same exact data Al Gore and the rest of the man-made global warmers refer to. The blue line is temps, the red, CO2 levels. The deep valleys represent 4 separate glaciation/ice-age periods. Look carefully at this historical relationship between temps and CO2 levels (the present is on the right hand side of the graph) and keep in mind that Gore claims this data is the 'proof' that CO2 has warmed the earth in the past. But does the data indeed show this? Nope. In fact, rising CO2 levels all throughout this 400,000-year period actually *followed* temperature increases -lagging behind by an average of 800 years! So it couldn't have been CO2 that got Earth out of these past glaciations. Yet Gore continually and dishonestly claims otherwise. Furthermore, the subsequent CO2 level increases due to dissolved CO2 being released from warming oceans, never did lead to additional warming, the so-called "run-away greenhouse effect" that Al Gore and his friends keep warning us about. In short, there is little if any evidence that CO2 had ever led to increased warming, at least not when the levels were within 10-15 times of what they are today. -etl

"The above chart shows the range of global temperature through the last 500 million years. There is no statistical correlation between the level of carbon dioxide in the atmosphere through the last 500 million years and the temperature record in this interval. In fact, one of the highest levels of carbon dioxide concentration occurred during a major ice age that occurred about 450 million years ago [Myr]. Carbon dioxide concentrations at that time were about 15 times higher than at present." [also see 180 million years ago, same thing happened]:

So, greenhouse [effect] is all about carbon dioxide, right?
Wrong. The most important players on the greenhouse stage are water vapor and clouds [clouds of course aren't gas, but high level ones do act to trap heat from escaping, while low-lying cumulus clouds tend to reflect sunlight and thereby help cool the planet -etl]. Carbon dioxide has been increased to about 0.038% of the atmosphere (possibly from about 0.028% pre-Industrial Revolution) while water in its various forms ranges from 0% to 4% of the atmosphere and its properties vary by what form it is in and even at what altitude it is found in the atmosphere.
In simple terms the bulk of Earth's greenhouse effect is due to water vapor by virtue of its abundance. Water accounts for about 90% of the Earth's greenhouse effect -- perhaps 70% is due to water vapor and about 20% due to clouds (mostly water droplets), some estimates put water as high as 95% of Earth's total tropospheric greenhouse effect (e.g., Freidenreich and Ramaswamy, 'Solar Radiation Absorption by Carbon Dioxide, Overlap with Water, and a Parameterization for General Circulation Models,' Journal of Geophysical Research 98 (1993):7255-7264).
The remaining portion comes from carbon dioxide, nitrous oxide, methane, ozone and miscellaneous other 'minor greenhouse gases.' As an example of the relative importance of water it should be noted that changes in the relative humidity on the order of 1.3-4% are equivalent to the effect of doubling CO2.

Water Vapor Rules the Greenhouse System
Water vapor constitutes Earth's most significant greenhouse gas, accounting for about 95% of Earth's greenhouse effect (4). Interestingly, many 'facts and figures' regarding global warming completely ignore the powerful effects of water vapor in the greenhouse system, carelessly (perhaps, deliberately) overstating human impacts as much as 20-fold.
Water vapor is 99.999% of natural origin. Other atmospheric greenhouse gases, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and miscellaneous other gases (CFC's, etc.), are also mostly of natural origin (except for the latter, which is mostly anthropogenic).
Human activities contribute slightly to greenhouse gas concentrations through farming, manufacturing, power generation, and transportation. However, these emissions are so dwarfed in comparison to emissions from natural sources we can do nothing about, that even the most costly efforts to limit human emissions would have a very small-- perhaps undetectable-- effect on global climate.

Water Vapor Confirmed As Major Player In Climate Change
ScienceDaily (Nov. 18, 2008) — Water vapor is known to be Earth's most abundant greenhouse gas, but the extent of its contribution to global warming has been debated. Using recent NASA satellite data, researchers have estimated more precisely than ever the heat-trapping effect of water in the air, validating the role of the gas as a critical component of climate change.

I have been seeing this unexplainable shift in government opinion on globull warming. Sound to me like they are setting up “justification” to drop c(r)ap and trade so they can do one of their other remaining “big three”
Gun Registration
Criminal Illegal Alien amnesty
Communist health “care”
I don’t think they believe they can get all of that in before the mid-terms and they are right.
I don’t think they can get any of it without getting kicked out of both the House and the Senate at the mid-terms.
They probably will get hammered in the House and the Senate anyway, just over the Ten Trillion Dollar deficit they are creating.
It’s 46 in May.... Please send some global warming. My furnace is still running.
That “with a low degree of scientific understanding” leaped out at me too. We have a “with a low degree of scientific understanding” of our climate and how it does what it does and yet they can shut down entire industries because of it. Now, there are counter indications (that they are admitting to) and suddenly a “low degree” of understanding is a bad thing. I guess Lib “scientists” haven’t voted on it yet to obtain their much heralded but scientifically irrelevant “consensus.”
Right now, our biggest threat is TICKS. It's springtime (sorta) and the warmth is stirring them! I hate them almost as much as the calamatists!
Ticks and calamatists: one’s a blood sucking parasite and the other is a bug.
I’m expecting the EPA to ban carbonated beverages; after all, they are mostly water (a greenhouse gas) and dissolved carbon dioxide (another greenhouse gas).
If they do this, they only prove they are exceptionally stupid, to modern society's detriment.
To ban contrails would not only eliminate aircraft because there is no way to prevent water vapor from airplane engines.....
.....But even if the water vapor was invisible (no contrail), there would still be water vapor.
This would also affect cooling towers, smokestack, and vehicles since there is a lot of water in the products of combustion (laying bare the notion that we are somehow using up water in the modern world).
In addition, water vapor is 100% uncontrollable. It forms and condenses constantly by the sun's action.
The amount that man adds is absolutely a TINY FRACTION of that which is made by nature.
Do you know of any research that correlates the output of carbon from human activity to the amount of carbon in the atmosphere over say, the last 200 years?
The AGW people always talk about this correlation, yet I can’t remember a ever seeing a chart that shows the relationship.
Not sure at the moment. I’m on my way out now. Check the water vapor links I provided earlier. Or do some internet searches.
The cirrus clouds and contrails cause some small amount of warming. Water vapor below 15 or 20k feet causes nothing compared to natural water vapor. So smokestacks etc are irrelevant. Of course plane contrails are mostly irrelevant too.
The file global.1751_2006.ems has the global totals.
Very useful. Thank you very much!
