Cap and Trade

Today it is time to talk about cap and trade. I am sure now that it is going to be imposed as a priority program in the USA and very likely in both India and China. It can become the first international revenue/expenditure model in place that will help create common cause on a global scale.

It took the fear of global warming (wrong reason) to make this program possible. By monetizing the disposal of CO2, it becomes profitable to solve the problem. This means that it creates demand for solutions that is driven by something other than altruism. I have thought for years that any and all waste disposal problems were best monetized just like this so that the invisible hand of the market can do its magic. Otherwise that invisible hand is quite happy to send it downstream unto its neigbours.

We have reached an historical pass in which even the statist gimme crowd supports such an idea, although they would never admit that they are calling on Adam Smith. It is actually the right thing to do and it needs to be fully internationalized, while grandfathering and scheduling out the advantage players, including India and China.

I find it offensive that we have torn down obsolete super polluters and shipped them off to China. These are now twenty years older and long paid for and surely ready for disposal. Much better technologies are now available and need to be encouraged by fast write offs and loan support.

A really good start in the USA since the cash value of a ton of carbon may be about $40.00 would be to convert all agricultural subsidies into carbon credits upon the farm sequestering the appropriate ton of carbon in the farm’s soils. If Europe did the same, we will have killed two birds with one stone. The farmers will actually earn their subsidies. The subsidies will no longer be paid by the tax payer but by the carbon polluters. With any luck that will jump start the terra preta soil revolution in the USA.

It will also establish a new global agricultural regime that will be more easily directed into extending these same systems everywhere else. I would love to subsidize new terra preta soils in the Phillipines at the rate of $40 per acre per year per ton of carbon while converting tropical soils into lush croplands forever. That would swiftly put millions to work establishing family farms like the family farms that existed in the Amazon for thousands of years. And modern mechanization allows these operations to be economically sized and operated.

This will also swiftly end slash and burn agriculture.

I know that this can be done right. My misgivings come from the unlimited capacity of the stupid and ignorant to divert programs like this into their own dreams of self aggrandizement, making it all messy for everyone else.

We only need to look at the ease which the mortgage industry bought off Congress to prolong their death spiral to know how possible this is. Can we keep them honest or do we have to walk through a history of swindles before it is done right? I am not too trusting these days.

Roosevelt and his brain trust did get a lot of things right back in the thirties. That is why I was so disturbed when Congress merrily took of the governors as a late action of the Clinton administration. To be followed by a smuck whose grasp of economic history was modest and clearly prone to been hoodwinked by folks he thought were on his side.

Obama and his brain trust have an opportunity to get this right, principally because the folks in office on both sides of the house have a lot to account for. But he better be prepared for an arm wrestle. Clinton ran into an unchastened house that was unprepared to give up anything and this immediately emasculated him for the entirety of his mandate.

So far Obama’s cabinet choices are fairly conservative and certainly careful. And he already knows what is top of the agenda as the auto industry has been given a stay of execution for three months to sort things out.

By the way, a subsistence farmer can be expected, using terra preta, to sequester one ton per year of carbon while upgrading one acre of soil per year. Therefore, removing 100,000,000 tons of carbon per year requires 100,000,000 families to be paid $40 for a total of $4 billion dollars. Maybe we can get Mohammed Younis to administer the program rather than the UN.


Connecting the Carbon Dots

By Nick Hodge Friday, December 19th, 2008
Pee-Wee Herman used to sing, "Connect the dots... laa la laa la laa," as he leapt into the magic screen.


No, I haven't been hanging out with Pee-Wee in movie theaters. But his advice on connecting the dots is applicable in the context of financial and political realms... and the trends and investment ideas that emerge.

Since the election in November, a series of dots have been emerging that indicate it's time to take a serious look at recently-established carbon ETFs and ETNs.

Connecting the Carbon Dots

In naming his climate change and energy team last week, Mr. Obama nominated Lisa Jackson to head the Environmental Protection Agency.

In her previous position, Jackson led the New Jersey Department of Environmental Protection, where she is credited with helping put New Jersey in a leadership role on the issue of climate change and with encouraging the state to adopt a moratorium on building new coal plants.

She also championed the reduction of emissions. And, in 2007, New Jersey became the third state, behind California and Hawaii, to pass a law that mandates steep emissions cuts over the next four decades.

New Jersey, under Jackson's direction, also helped establish the Regional Greenhouse Gas Initiative (RGGI), the first mandatory, market-based CO2 emissions reduction program in the United States.

A "market-based" program means it is possible to profit from reducing emissions.

And I suspect, under her leadership, the EPA will push through a similar measure that covers the entire country. You may know it as a cap-and-trade system.

Her new boss is certainly on board. The 'agenda' section of his website has the following three things to say about changing our carbon habits:

· Reduce our Greenhouse Gas Emissions 80 Percent by 2050

· Implement an economy-wide cap-and-trade program to reduce greenhouse gas emissions 80 percent by 2050

· Make the U.S. a Leader on Climate Change.

Obama has already said he'll consider asking the EPA to regulate emissions under the Clean Air Act, which is something they should've been doing already, but Bush declined to do so after saying that such a plan would turn the EPA into the "de facto regulator of the economy."

In response, Jackson sent a forceful letter to the EPA saying that "the past eight years have demonstrated a shocking, yet consistent, irresponsibility on the part of the federal government to engage in any meaningful way... in implementing sustainable solutions to reduce emissions."

I think the policies she intends to carry out in her new position are clear.




Here we have an attack rant against cap and trade. He is right of course, if no carbon ever gets sequestered, and he is not about to investigate the possibilities. The object is to monetize the carbon waste stream. My object is to use that to monetize the two billion or so subsistence farmers so that their enterprise is recognized as capital.



The Cap And Trade Fraud - Global Warming Scams


by Jack Ward

The big buzz in the political world is 'cap and trade'. What is cap and trade and where did this idea come from?

The cap and trade concept came from the UN's Kyoto Protocols. Cap and trade is based on the flawed premise that anthropogenic activities (humans) are causing global warming by increasing
carbon dioxide (CO2) in the atmosphere. The American Physical Society (APS), which represents nearly 50,000 physicists, has reversed its previous position on climate change. APS editor, Jeffrey Marque said, "There is a considerable presence within the scientific community of people who do not agree with the ICCP (Intergovernmental Panel on Climate Change) conclusion that anthropogenic CO2 emissions are very probably likely to be primarily responsible for global warming that has occurred since the Industrial Revolution." The UN IPCC computer modeling contains numerous exaggerations and extensive errors which led to the global warming hoax.

Virtually all human activities (work and play) results in the release of CO2. A cap and trade scheme would limit the release of CO2 that countries, corporations, and individuals could emit. Those that exceed this arbitrary carbon cap would be required to buy or trade a carbon
credit from a country, corporation or individual that did not exceed the arbitrary cap. A carbon credit is a permit that allows a country, corporation, or an individual to emit a specified amount of carbon dioxide. These credits are bought and sold on carbon trading markets just like stocks. Contrary to stocks that have an actual value, the value of carbon credits is artificially created by governments for the sole purpose of generation income from a commodity that has no actual value. In a free market economy no one in their right mind would pay good money for a commodity that has no value without government coercion.

The buying, selling, and
trading carbon credits will not remove one molecule of CO2 from the atmosphere. But, the purpose is not to eliminate CO2, it is to generate income for the government, redistribute wealth, and control the people. Yet Obama said, "Under my plan of a cap and trade system, electricity rates would necessarily skyrocket. Even regardless of what I say about whether coal is good or bad. Because I'm capping greenhouse gases, coal power plants, you know, natural gas, you name it — whatever the plants were, whatever the industry was, uh, they would have to retrofit their operations. That will cost money. They will pass that money on to consumers."

According to the Congressional Budget Office this new energy tax will cost businesses and individuals trillions of dollars. In addition, legislative analysts have predicted that millions of jobs will be lost if legislation implementing the cap and trade proposal is passed. Once these schemes are allowed, the government will be able to regulate and control all carbon emissions. This will give the government complete control over travel, lifestyle and what ever businesses and citizens consume and produce. This is the change Obama desires.

Cap and trade advocates chose the Hegelian Dialectic to sell this draconian plan. Georg Hegel's theory of the dialectic was used by Karl Marx and Frederick Engels to sell their economic theory of
Communism. The Hegelian Dialectic is used to guide thoughts and actions that lead to a predetermined solution. Here is how it's done:

* First, create a problem of monumental proportions.

* Second, stir up hysteria by every means possible.

* Third, when people hysterically demand a solution to the contrived problem, offer predetermined solutions that will take away rights, cost considerable money, and put more power in the hands of the power-grabbing bureaucrats.

Global warming zealots are using the Hegelian Dialectic to push their environmental agenda to the detriment of the American people. People are being brainwashed into believing the planet is being threatened by global warming. Speaker of the House, Nancy Pelosi, even claims that she was elected to 'save the planet'. Al Gore, the self appointed high priest of global warming, lectures everyone to reduce their energy consumption. But don't be fooled. Neither Peolsi nor Gore walks the walk. Both are multi-millionaires that live in energy gobbling mansions.

These elitist Liberals want to re-create a serf / royalty society, with them representing the royalty class. You will know when this global warming hype is for real when Gore, Pelosi, and their ilk give up the amenities of the 'rich and famous' and live in 1600 sq. ft. houses, fly coach, and use mass transit. Until then, their hot air is the cause of global warming. Every aspect of your life will be adversely affected if our politicians are allowed to implement any of these fraudulent cap and trade schemes.

David Evans Recants

This article out on the clear lack of any linkage between CO2 and global warming can hardly be starker. David Evans direct involvement in the science and data gathering around the global warming – CO2 hypothesis put him in the position of been an informed apologist for the theory. Thus his recanting any support for the position is very important. It is always difficult to pry oneself loose from a position that you have loyally supported in good faith. It was surely difficult for him.

Again, shifting global temperatures and rising CO2 is not disputed. The idea that they are linked is in question as I have always maintained in this blog.

What this article adds that I find new is that a CO2 causation hypothesis as with any other hypothesis must have a hotspot that is a direct result of the predicted behavior. As he makes very clear, that signal is completely missing.

This does not take away from the fact that the environment has failed to suck up all the CO2 that we have produced or that responsible husbandry means that we do something about it. Which over the next generation we certainly can.

The globe, and let us be a little more precise and say the northern hemisphere, has warmed about a half degree to a degree over the last one hundred years. Our unreliability over land measurements creates an error range that could even account for this apparent gain.

The only fact that we can be sure does not simply fit inside the historical range of conditions over the two hundred years, is that the severe cold of the little ice age has now fully abated. Growing grapes in England is surely once again an option and once the permafrost is gone in Greenland, the dairy industry can restart.
The loss of perennial sea ice fits this scenario very nicely.

In the meantime our satellites have observed a recent temperature drop of .6 degrees. They had observed a modest rise since they began back in 1979. This will be worth monitoring over the next year to see how responsive it really is and how sustained this drop is.

I do not want to sound suspicious, but one of the most insidious problems with computer supported continuous data gathering is that baseline algorithms that are updated without independent correction systems can accumulate rounding errors. This usually leads to a positive or negative trend line that eventually leads to a recalculation and an abrupt reset.

Of course I do not have the data to look at, so we have assumed this abrupt change is real. Is it sustainable? Why is such an abrupt change possible? Where did the heat go?

The only thing that we can be sure of this year is that the perennial sea ice is continuing its collapse. The press is now starting to call it a death spiral which it is. Unless that purported .6 degree temperature decline turns into a three to four degree drop in the Arctic, there is nothing to halt this trend. We shall see.

I had thought that the historical land temperature work up had been largely settled, including the urban island problem. However, we have already had recent corrections that put the current regime on a par with the 1930’s. He does reopen the issue and I would like to see more on it. A corrective fudge factor could produce a lot of error all by itself.


Why I recanted

'There is no evidence to support the idea that carbon emissions cause significant global warming'
David Evans, Financial Post Published: Saturday, August 30, 2008

I devoted six years to carbon accounting when I built models for the Australian Greenhouse Office. I am the rocket scientist who wrote the carbon accounting model (FullCAM) that measures Australia's compliance with the Kyoto Protocol, in the land use change and forestry sector.

FullCAM models carbon flows in plants, mulch, debris, soils and agricultural products, using inputs such as climate data, plant physiology and satellite data. I've been following the global warming debate closely for years.
When I started that job in 1999 the evidence that carbon emissions caused global warming seemed pretty good: CO2 is a greenhouse gas; the old ice core data; no other suspects.

The evidence was not conclusive, but why wait until we were certain when it appeared we needed to act quickly? Soon governments and the scientific community were working together and lots of science research jobs were created. We scientists had political support, the ear of government, big budgets and we felt fairly important and useful (well, I did anyway). It was great. We were working to save the planet.

But since 1999, new evidence has seriously weakened the case that carbon emissions are the main cause of global warming, and by 2007 the evidence was pretty conclusive that carbon played only a minor role and was not the main cause of the recent global warming. As Lord Keynes famously said, "When the facts change, I change my mind. What do you do, sir?"

There has not been a public debate about the causes of global warming and most of the public and our decision makers are not aware of the most basic salient facts:

1. The greenhouse signature is missing. We have been looking and measuring for years, and cannot find it.

Each possible cause of global warming has a different pattern of where in the planet the warming occurs first and the most intensely. The signature of an increased greenhouse effect is a hot spot about 10 km up in the atmosphere over the tropics. We have been measuring the atmosphere for decades using radiosondes: weather balloons with thermometers that radio back the temperature as the balloon ascends through the atmosphere. They show no hot spot. Whatsoever.

If there is no hot spot then an increased greenhouse effect is not the cause of global warming. So we know for sure that carbon emissions are not a significant cause of the global warming. If we had found the greenhouse signature then I would be an alarmist again.

When the signature was found to be missing in 2007 (after the latest IPCC report), alarmists objected that maybe the readings of the radiosonde thermometers might not be accurate and maybe the hot spot was there but had gone undetected. Yet hundreds of radiosondes have given the same answer, so statistically it is not possible that they missed the hot spot.

Recently the alarmists have suggested we ignore the radiosonde thermometers, but instead take the radiosonde wind measurements, apply a theory about wind shear, and run the results through their computers to estimate the temperatures. They then say that the results show that we cannot rule out the presence of a hot spot. If you believe that you'd believe anything.

2. There is no evidence to support the idea that carbon emissions cause significant global warming. None. There is plenty of evidence that global warming has occurred, and theory suggests that carbon emissions should raise temperatures (though by how much is hotly disputed) but there are no observations by anyone that implicate carbon emissions as a significant cause of the recent global warming.

3. The satellites that measure the world's temperature all say that the warming trend ended in 2001, and that the temperature has dropped about 0.6 degrees Celsius in the past year (to the temperature of 1980). Land-based temperature readings are corrupted by the "urban heat island" effect: urban areas encroaching on thermometer stations warm the micro-climate around the thermometer, due to vegetation changes, concrete, cars, houses.
Satellite data is the only temperature data we can trust, but it only goes back to 1979. NASA reports only land-based data, and reports a modest warming trend and recent cooling. The other three global temperature records use a mix of satellite and land measurements, or satellite only, and they all show no warming since 2001 and a recent cooling.

4. The new ice cores show that in the past six global warmings over the past half a million years, the temperature rises occurred on average 800 years before the accompanying rise in atmospheric carbon. Which says something important about which was cause and which was effect.

None of these points are controversial. The alarmist scientists agree with them, though they would dispute their relevance.

The last point was known and past dispute by 2003, yet Al Gore made his movie in 2005 and presented the ice cores as the sole reason for believing that carbon emissions cause global warming. In any other political context, our cynical and experienced press corps would surely have called this dishonest and widely questioned the politician's assertion.

Until now, the global warming debate has merely been an academic matter of little interest. Now that it matters, we should debate the causes of global warming.

So far that debate has just consisted of a simple sleight of hand: show evidence of global warming, and while the audience is stunned at the implications, simply assert that it is due to carbon emissions.

In the minds of the audience, the evidence that global warming has occurred becomes conflated with the alleged cause, and the audience hasn't noticed that the cause was merely asserted, not proved.

If there really was any evidence that carbon emissions caused global warming, don't you think we would have heard all about it ad nauseam by now?

The world has spent $50-billion on global warming since 1990, and we have not found any actual evidence that carbon emissions cause global warming. Evidence consists of observations made by someone at some time that supports the idea that carbon emissions cause global warming. Computer models and theoretical calculations are not evidence, they are just theory.

What is going to happen over the next decade as global temperatures continue not to rise? The Australian Labor government is about to deliberately wreck the economy in order to reduce carbon emissions. If the reasons later turn out to be bogus, the electorate is not going to re-elect a Labor government for a long time. When it comes to light that the carbon scare was known to be bogus in 2008, the ALP is going to be regarded as criminally negligent or ideologically stupid for not having seen through it. And if the Liberals support the general thrust of their actions, they will be seen likewise.

The onus should be on those who want to change things to provide evidence for why the changes are necessary. The Australian public is eventually going to have to be told the evidence anyway, so it might as well be told before wrecking the economy. - David Evans was a consultant to the Australian Greenhouse Office from 1999 to 2005.

Water Vapor

I have steered clear of directly tackling the CO2 causation theory and its mechanisms except to merely maintain that the linkage is unnecessary in terms of human decision making. After all, it is obviously not smart to jack up CO2 levels blindly and to then hope for the best. And changing weather within its historical parameters is not a compelling argument either.

I thought that it would be worthwhile however to copy these two items that addresses the issue of water vapor and indirectly the use of its omission to seriously overstate the effect of other greenhouse gases. This is a subtle way to manipulate data that will get past all but the most informed insiders to the debate.

The fact is the CO2 linkage was controversial and challenged during its early promotion. I have seen little in the way of answers to these criticisms, but time and expanding public acceptance of what essentially is a great story has silenced most serious critics, or at least outlived them.

I have observed this effect repeatedly were a fairly weak theory is accepted and removed from serious criticism for a great span of time. Usually this is a harmless pastime as was the silly idea of rising and falling land bridges when any school child could observe the obvious existence of crustal separation. It is not harmless when governments divert resources toward wrongheaded schemes in pursuit of these ghosts.

This came out in 1999 through the Fraser Institute and is part of a larger review article.

Exaggerated warming



The computer projections are exaggerating the greenhouse warming by a large factor, partly because they are subject to major errors due to the assumption that water vapor is a strong, positive feedback.

But the effect of water vapor is not understood.

In calculating the response to climatic forcing it is important to note that the computer simulations rely on a positive feedback provided by water vapor in the upper troposphere to amplify the small warming directly resulting from the increase in carbon dioxide and other minor greenhouse gases.

This amplification is the predominant source of temperature gain in the computer simulations.

"This feedback operates in all the climate models used in global warming and other studies". (IPCC I 1996: 200, 4.2.1).

However, note: "Intuitive arguments for the feedback to apply to water vapor in the upper troposphere are weak; observational analyses and process studies are needed to establish its existence and strength there" (200, 4.2.1).

Also: "Feedback from the redistribution of water vapor remains a substantial uncertainty in climate models" (201, 4.2.1). The assumption that the feedback from water vapor is positive has been challenged by theory (Sun and Lindzen 1993: 1643) and by observations (Spencer and Braswell 1997: 1097).


Without the assumed gain from the water-vapor feedback, there would be little amplification of the warming caused by the increases in the minor greenhouse gases (Lindzen 1994: 353).

What, then, is the maximum amount of warming due to increased greenhouse gases that can be expected to occur, if the exaggerated forecasts are reduced to the limits allowed by the actual temperature measurements?

The answer is that the corrected warming in the next century, at present rates of increase in the greenhouse gases, will be less than a few tenths of a degree Celsius.

This second item was published in 2003 by Monte Hieb and tackles the subject with appropriate calculation.

Water Vapor Rules
the Greenhouse System

Just how much of the "Greenhouse Effect" is caused by human activity?

It is about 0.28%, if water vapor is taken into account-- about 5.53%, if not.

This point is so crucial to the debate over global warming that how water vapor is or isn't factored into an analysis of Earth's greenhouse gases makes the difference between describing a

significant human contribution to the greenhouse effect, or a negligible one.

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 activites 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 missions would have a very small-- perhaps undetectable-- effect on global climate.

For those interested in more details a series of data sets and charts have been assembled below in a 5-step statistical synopsis.

Note that the first two steps ignore water vapor.

1. Greenhouse gas concentrations

2. Converting concentrations to contribution

3. Factoring in water vapor

4. Distinguishing natural vs man-made greenhouse gases

5. Putting it all together

Note: Calculations are expressed to 3 significant digits to reduce rounding errors, not necessarily to indicate statistical precision of the data. All charts were plotted using Lotus 1-2-3.

Caveat: This analysis is intended to provide a simplified comparison of the various man-made and natural greenhouse gases on an equal basis with each other. It does not take into account all of the complicated interactions between atmosphere, ocean, and terrestrial systems, a feat which can only be accomplished by better computer models than are currently in use.


Greenhouse Gas Concentrations:
Natural vs man-made (anthropogenic)

1. The following table was constructed from data published by the U.S. Department of Energy (1) and other sources, summarizing concentrations of the various atmospheric greenhouse gases. Because some of the concentrations are very small the numbers are stated in parts per billion. DOE chose to NOT show water vapor as a greenhouse gas!

The chart at left summarizes the % of greenhouse gas concentrations in Earth's atmosphere from Table 1. This is not a very meaningful view though because 1) the data has not been corrected for the actual Global Warming Potential (GWP) of each gas, and 2) water vapor is ignored.

But these are the numbers one would use if the goal is to exaggerate human greenhouse contributions:

Man-made and natural carbon dioxide (CO2) comprises 99.44% of all greenhouse gas concentrations (368,400 / 370,484 )--(ignoring water vapor).

Also, from Table 1 (but not shown on graph):

Anthropogenic (man-made) CO2 additions comprise (11,880 / 370,484) or 3.207% of all greenhouse gas concentrations, (ignoring water vapor).

Total combined anthropogenic greenhouse gases comprise (12,217 / 370,484) or 3.298% of all greenhouse gas concentrations, (ignoring water vapor).

The various greenhouse gases are not equal in their heat-retention properties though, so to remain statistically relevant % concentrations must be changed to % contribution relative to CO2. This is done in Table 2, below, through the use of GWP multipliers for each gas, derived by various researchers.


Converting greenhouse gas concentrations

(using global warming potential )

2. Using appropriate corrections for the Global Warming Potential of the respective gases provides the following more meaningful comparison of greenhouse gases, based on the conversion:

( concentration ) X ( the appropriate GWP multiplier (2) (3) of each gas relative to CO2 ) = greenhouse contribution.:

NOTE: GWP (Global Warming Potential) is used to contrast different greenhouse gases relative to CO2.

Compared to the concentration statistics in Table 1, the GWP comparison in Table 2 illustrates, among other things:

Total carbon dioxide (CO2) contributions are reduced to 72.37% of all greenhouse gases (368,400 / 509,056)-- (ignoring water vapor).

Also, from Table 2 (but not shown on graph):

Anthropogenic (man-made) CO2 contributions drop to (11,880 / 509,056) or 2.33% of total of all greenhouse gases, (ignoring water vapor).

Total combined anthropogenic greenhouse gases becomes (28,162 / 509,056) or 5.53% of all greenhouse gas contributions, (ignoring water vapor).

Relative to carbon dioxide the other greenhouse gases together comprise about 27.63% of the greenhouse effect (ignoring water vapor) but only about 0.56% of total greenhouse gas concentrations. Put another way, as a group methane, nitrous oxide (N2O), and CFC's and other miscellaneous gases are about 50 times more potent than CO2 as greenhouse gases.

To properly represent the total relative impacts of Earth's greenhouse gases Table 3 (below) factors in the effect of water vapor on the system.

As illustrated in this chart of the data in Table 3, the combined greenhouse contributions of CO2, methane, N2O and misc. gases are small compared to water vapor!

Total atmospheric carbon dioxide (CO2) -- both man-made and natural-- is only about 3.62% of the overall greenhouse effect-- a big difference from the 72.37% figure in Table 2, which ignored water!

Water vapor, the most significant greenhouse gas, comes from natural sources and is responsible for roughly 95% of the greenhouse effect (4). Among climatologists this is common knowledge but among special interests, certain governmental groups, and news reporters this fact is under-emphasized or just ignored altogether.

Conceding that it might be "a little misleading" to leave water vapor out, they nonetheless defend the practice by stating that it is "customary" to do so!

of greenhouse gases

4. Of course, even among the remaining 5% of non-water vapor greenhouse gases, humans contribute only a very small part (and human contributions to water vapor are negligible).

Constructed from data in Table 1, the charts (below) illustrate graphically how much of each greenhouse gas is natural vs how much is man-made. These allocations are used for the next and final step in this analysis-- total man-made contributions to the greenhouse effect. Units are expressed to 3 significant digits in order to reduce rounding errors for those who wish to walk through the calculations, not to imply numerical precision as there is some variation among various researchers.



Putting it all together:
total human greenhouse gas contributions
add up to about 0.28% of the greenhouse effect.

5. To finish with the math, by calculating the product of the adjusted CO2 contribution to greenhouse gases (3.618%) and % of CO2 concentration from anthropogenic (man-made) sources (3.225%), we see that only (0.03618 X 0.03225) or 0.117% of the greenhouse effect is due to atmospheric CO2 from human activity. The other greenhouse gases are similarly calculated and are summarized below.

This is the statistically correct way to represent relative human contributions to the greenhouse effect.

From Table 4a, both natural and man-made greenhouse contributions are illustrated in this chart, in gray and green, respectively. For clarity only the man-made (anthropogenic) contributions are labeled on the chart.

Water vapor, responsible for 95% of Earth's greenhouse effect, is 99.999% natural (some argue, 100%). Even if we wanted to we can do nothing to change this.

Anthropogenic (man-made) CO2 contributions cause only about 0.117% of Earth's greenhouse effect, (factoring in water vapor). This is insignificant!

Adding up all anthropogenic greenhouse sources, the total human contribution to the greenhouse effect is around 0.28% (factoring in water vapor).

The Kyoto Protocol calls for mandatory carbon dioxide reductions of 30% from developed countries like the U.S. Reducing man-made CO2 emissions this much would have an undetectable effect on climate while having a devastating effect on the U.S. economy. Can you drive your car 30% less, reduce your winter heating 30%? Pay 20-50% more for everything from automobiles to zippers? And that is just a down payment, with more sacrifices to come later.

Such drastic measures, even if imposed equally on all countries around the world, would reduce total human greenhouse contributions from CO2 by about 0.035%.

This is much less than the natural variability of Earth's climate system!

While the greenhouse reductions would exact a high human price, in terms of sacrifices to our standard of living, they would yield statistically negligible results in terms of measurable impacts to climate change. There is no expectation that any statistically significant global warming reductions would come from the Kyoto Protocol.


" There is no dispute at all about the fact that even if punctiliously observed, (the Kyoto Protocol) would have an imperceptible effect on future temperatures -- one-twentieth of a degree by 2050. "

Research to Watch

Scientists are increasingly recognizing the importance of water vapor in the climate system. Some, like Wallace Broecker, a geochemist at Columbia's Lamont-Doherty Earth Observatory, suggest that it is such an important factor that much of the global warming in the last 10,000 years may be due to the increasing water vapor concentrations in Earth's atmosphere.

His research indicates that air reaching glaciers during the last Ice Age had less than half the water vapor content of today. Such increases in atmospheric moisture during our current interglacial period would have played a far greater role in global warming than carbon dioxide or other minor gases.


" I can only see one element of the climate system capable of generating these fast, global changes, that is, changes in the tropical atmosphere leading to changes in the inventory of the earth's most powerful greenhouse gas-- water vapor. "

Known causes of global climate change, like cyclical eccentricities in Earth's rotation and orbit, as well as variations in the sun's energy output, are the primary causes of climate cycles measured over the last half million years. However, secondary greenhouse effects stemming from changes in the ability of a warming atmosphere to support greater concentrations of gases like water vapor and carbon dioxide also appear to play a significant role. As demonstrated in the data above, of all Earth's greenhouse gases, water vapor is by far the dominant player.

The ability of humans to influence greenhouse water vapor is negligible. As such, individuals and groups whose agenda it is to require that human beings are the cause of global warming must discount or ignore the effects of water vapor to preserve their arguments, citing numbers similar to those in Table 4b . If political correctness and staying out of trouble aren't high priorities for you, go ahead and ask them how water vapor was handled in their models or statistics. Chances are, it wasn't!
