Why CO2 is not the cause of climate change

Does Carbon Dioxide cause climate change?

a) Carbon dioxide is a minor player in any further warming. It is uniformly distributed in the atmosphere but only absorbs infrared (heat) in a very narrow wavelength range. The CO2 wavelength range is outside the range of most of the solar radiance that penetrates our atmosphere. It falls roughly inside the wavelength range of temperatures re-radiated when solar radiation heats the earth’s surface. The atmospheric CO2 already absorbs almost all of the radiation that it can in that range. Most of the warming effect of CO2 has already occurred in the past and is one of the reasons our planet is not a frozen wasteland. Any increase in CO2 will have a very minor effect. With CO2 absorption near saturation, almost all of the re-radiated heat in that wavelength range is already being trapped, so it can have little or no effect on future increases in temperature or supposed forcing of water vapor. With CO2 essentially eliminated as a source, any increases in temperature must be from some other sources.

Absorption of gases – note narrow CO2 bands & broad water bands.

This figure requires a bit of explaining. The top spectrum shows the wavelengths at which the atmosphere transmits light and heat as well as the “black body” idealized curves for no absorption. It is a little misleading because the data is not based on actual solar and earth data. It is based on two experimental heat sources, one centered at 5525 K (5252o C or 9485o F), the approximate temperature of solar radiation, and one centered in the range of 210 to 310 K (-63o C to 36.8o C or -82oF to 98o F), the approximate temperature range of re-radiated heat from the earth. In reality solar radiation power, (Watts/m2/micron), shown in red, is six million times as strong as the power of re-radiated heat from the earth, shown in blue.

The other spectra are absorption[1] spectra. The top one shows the relative percent absorption by total atmospheric gases at various wavelengths, (note that this spectrum is practically the inverse of the transmission spectrum above it), and the spectra below that show the absorption wavelength ranges of individual atmospheric gases, but not the relative strength of that absorption in reality. As experimental, not real atmospheric, data they can only tell us the wavelength ranges of the absorption, not their relative strengths.

Note that CO2 absorbs in the 15 micron range[2], which is within both the range of re-radiated heat and the strong absorption by water vapor of which the CO2 peak forms a mere shoulder. This is used to claim forcing of water vapor by CO2, without regard to the near-saturation level of CO2. Lesser CO2 peaks in the 2.7 and 4.3 micron ranges also only contribute in a minor way, the first is completely covered by a water vapor absorption peak and the second forms a shoulder in another water vapor peak. These minor peaks occur in a region where both solar radiation and re-radiation are minimized. Methane and nitrous oxide are also shown to be minor players, having narrow absorption ranges and low concentrations. Note too that ozone blocks most of the ultraviolet light from the sun.

b.) Water is by far the most important greenhouse gas/liquid in the form of vapor, high and low altitude clouds, rain and snow, which both absorb and reflect sunlight and re-radiated heat from the surface. Water vapor is not uniformly distributed in the atmosphere, being concentrated near the earth, but strongly absorbs heat in a wide range of wavelengths. More heat means more water vapor evaporating from the oceans. Sounds pretty scary, doesn’t it? Contrary to what is assumed by climate modelers, who use this to claim forcing by CO2, the extra vapor doesn’t remain as vapor. It quickly forms low altitude clouds that strongly reflect in-coming sunlight and heat into space. Any re-radiated heat from the surface that may be trapped by clouds is a small fraction compared to the in-coming solar radiation, so blocking solar radiance has a net cooling effect that overwhelms any increases in trapped re-radiation. High altitude clouds tend to trap heat from being re-radiated into space, but have little effect because the increases in cloud cover due to warming are mostly in low altitude clouds.

[1] Transmission and Absorption are inversely related by the formula A = 1/log T.

Carbon Dioxide is plant food and increases growth rates

Animals exhale Carbon Dioxide (CO2) and breathe Oxygen (O2), while plants use CO2 and exhale O2. Professional greenhouses often add extra CO2 to increase growth rates. Increased plant growth removes much of the CO2 released into the atmosphere. Between pre-industrial and present times, studies show an average of 15% increase in plant growth rates, with some species increased many times that, e.g. young pine trees. Increased plant growth rates and wider distribution of arable (farmable) land due to warming as well as improved farming practices can solve the so-called overpopulation problem. If much of the data used in the climate models are based on proxy data from tree rings, and growth has been increased by CO2, does that mean that the data is artificially skewed toward “warmer” results? Hmmm.

A. Critics created the “progressive nitrogen limitation hypothesis,” which assumes that increased growth rates of trees would deplete poor soils of nitrogen, thus mediating the positive effects of increased CO2. This is a scenario based on theory, not reality, which stubbornly refuses to support the hypothesis. Many studies[1] show that, contrary to the hypothesis, although roots grow deeper and produce more fine hairs, soil and forest floor are enriched in nitrogen from biological sources, i.e. increased root mass and leaf litter supporting beneficial microbes in the soil.

B. One benefit of increased CO2 is that the stomata (openings) of leaves, which take in CO2 and emit water vapor and oxygen, are reduced, leading to less water loss, enhanced water use and improved tolerance to dryer conditions. At elevated CO2 levels, stomata do not need to be open as far to allow sufficient CO2 in for photosynthesis and, as a result, less water is lost through transpiration[2]. In controlled studies, an additional benefit of reduced stomata openings is a reduction of ozone damage.

C. The increased rate of growth of plants, from forests to sea algae, results in more of certain cooling aerosols being produced. These include Carbonyl Sulfide (COS) from soil and seas that become highly reflective sulfate in the stratosphere to reflect more solar radiation back into space, Iodo-compounds from sea algae that nucleate clouds to reflect more solar radiation back into space, dimethyl sulfide (DMS), from seas that nucleates clouds and other aerosols such as isoprene from trees with similar effects.

D.  Hormesis is a phenomenon, commonly seen in medicine and nutrition, where a low concentration or dose results in a positive effect, but a larger dose results in damage. For instance, some salt and water are necessary to good health, but beyond a certain point, ingesting more can be harmful or fatal. The effect of CO2 on plant life appears to be one such system. Increased CO2 obviously benefits plant life, but it is uncertain at what level CO2 might have a detrimental effect on growth. In professional greenhouses and experiments, even ten times the current level is still beneficial.

As a matter of fact, CO2 below 400 ppm restricts growth, and below 150 ppm plants die en masse.  For a good summary of this, see post at http://notrickszone.com/2013/05/17/atmospheric-co2-concentrations-at-400-ppm-are-still-dangerously-low-for-life-on-earth/ by posted on 17.

Calculated Chaos: Renewable Energy Zealot’s Wind & Solar Plan for California Just Doesn’t Add Up


Mad Bill doesn’t just look like a zealot …

Facts, reason and logic have never troubled the true believers in our ‘inevitable transition’ to an all wind and sun powered future.

Trifling matters, like cost and reliability, are dismissed in an instant. The slaughter of millions of birds and bats, swept under the carpet. And the environmental havoc wreaked across countryside carpeted in thousands of toxic turbines and solar panels from horizon to horizon, is deemed to be all for the greater good.

They’re not called zealots, for nothing. As Robert Bryce details below.

Back in 2012, the environmental organization 350.org and its leader, Bill McKibben, took a “Do the Math” tour across America to talk about “the terrifying math of the climate crisis.” Alas, it appears McKibben has since developed an allergy to simple arithmetic.

Reality Bites: ‘Transition’ to All Wind & Solar Powered Future Pure Fantasy



Plenty of destructive ideas have been launched on the back of well-crafted propaganda campaigns. The wind and solar industries have used every trick in the PR book, turning pure fantasy into an all-too-real nightmare.

Where electricity was once an essential service, which governments went out of their way to insure was available to all-comers, heavily subsidised, weather dependent wind and solar have trashed that idea. Nowadays, governments of all persuasions have taken to educating the populous that they are ‘demand resources’ and subject to ‘demand management’. That is, unceremoniously chopping the power supply to households and businesses, whenever the sun sets or calm weather sets in.

Rocketing power prices have a more immediate and permanent effect – tens of thousands of Australian households can no longer afford electricity and have had their power cut off, completely: Australia’s Self-Inflicted Renewable Energy Crisis: 200,000 Families Can’t Afford Power

Censorship and Corruption in science

Climate Change Science, aka Religion, is Corrupted by Censorship of Critical Scientists

I hope you will take the time to listen to this Youtube video in which Dr. Willie Soon gives evidence of scientific censorship.  He has been the target of intimidation, censorship and vicious lies because he uses real scientific data to refute alarmist claims by Climate Change Advocates in academia and scientific publishing. Even if you choose not to view the video, please read his conclusions below.

Conclusion #1:  The dark cloud of censorship and intimidation is sweeping across [the] climate science arena in full display now. Climate science, as we know it, is dangerously invaded and corrupted by scientism. The big bad bullies of censorship, those scientists, scientific institutions and funding agencies, continue to be calling [the] shots and making decisions in just about any matter that is important to science, and that has to be stopped.

Conclusion #2: Nearly all institutions are essentially populated and controlled by activists and alarmists, rather than curious scientists, that are firmly convinced of the great harms of CO2 without any need nor interest for scientific evidence.

The so-called “Deniers” are not the real science deniers. It is the “Warmists” among scientists, turned advocates, who refuse to look at any data/ information that does not agree with their fore-gone conclusions and with models that do not track reality. For example, they firmly refuse to consider any contribution from the Sun or Water Vapor and Clouds.

“The common enemy of humanity is man. In searching for a new enemy to unite us, we came up with the idea that pollution, the threat of global warming, water shortages, famine and the like would fit the bill. All these dangers are caused by human intervention, and it is only through changed attitudes and behaviour that they can be overcome. The real enemy then, is humanity itself.” (emphasis added)

Water Wars: Wind Turbine Construction Destroying Underground Water Supplies in Ontario


Pundits have predicted that the next major war will be sparked over water. In Ontario just such a battle is (pardon the pun) well underway.

A couple of weeks back STT reported on the destruction of underground water supplies in Chatham-Kent: Ontario: Water, Water Everywhere – But Thanks to Wind Turbines – Not A Drop to Drink

While that story has clocked up almost 4,000 hits, it seems we only just scratched the surface.

Locals are furious, not just at the fact that once pristine water supplies have been turned to toxic sludge, they are wild at the way wind power outfits and their pet consultants are lying about the cause.

The first story goes right to the heart of that piece of wind industry spin.

Fact Factory: Smashing Big Wind Starts & Ends With Data & Detail

Very useful data and facts from stopthesethings.com blog about harm to birds, bats, etc. and the real cost and imaginary benefits of offshore wind turbines.


What the wind industry hates most are facts; facts about rocketing power prices, massive subsidies, chaotic intermittency, incessant noise and consequent harm to neighbour’s health, the destruction of birds and bats, the destruction of underground water supplies, turbines spontaneously combusting, disintegrating or throwing their blades to the four winds. We could go on.

On this occasion, however, we’ll hand over to our American cousins from the North American Platform Against Windpower, who deal with all of the above and more in a cracking and compendious letter to the Ohio Power Siting Board (and others) about plans to spear a clutch of massive Vestas 3.45 MW whirling wonders into the shores of Lake Erie, in Cleveland, Ohio.
