Why CO2 is not the cause of climate change

Does Carbon Dioxide cause climate change?

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 source.

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.

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.

$1.5 Trillion Climate Change Industry Equal to All Online Retail Sales.

Spot the Vested Interest: The $1.5 Trillion Climate Change Industry – from JoNova website

Climate Change Business Journal estimates the Climate Change Industry is a $1.5 Trillion dollar escapade, which means four billion dollars a day is spent on our quest to change the climate. That includes everything from carbon markets to carbon consulting, carbon sequestration, renewables, biofuels, green buildings and insipid cars. For comparison global retail sales online are worth around $1.5 trillion. So all the money wasted on the climate is equivalent to all the goods bought online.

The special thing about this industry is that it wouldn’t exist if it weren’t for an assumption about relative humidity that is probably wrong. As such, it’s the only major industry in the world dependent on consumer and voter ignorance. This is not just another vested interest in a political debate; it’s vested-on-steroids, a mere opinion poll away from extinction. You can almost hear the captains of climate industry bellowing: “Keep ‘em ignorant and believing, or the money goes away!”.

To state the obvious:

Policy, or the anticipation of new policy, has been one of the biggest drivers of the industry, the report shows.

Most industries this size exist because they produce something the market wants. They worry that competitors might chip into their market share, but they don’t worry that the market might disappear overnight. Normal industries fear that a “bad” political outcome might reduce profits by ten or twenty percent, and sometimes they donate “both ways”. But the climate industry has literally a trillion on the table that depends on big-government policy and election outcomes. They are always one prime-time documentary away from disaster. What if the public saw that thermometers were next to industrial exhaust vents? What if they learned that the climate models are unskilled, broken, and non-functional, or that 28 million weather balloons show carbon reduction is fruitless pursuit? What if they knew historic records are wildly adjusted to make the current weather look warmer than it would? …

In case you missed it, over the weekend, Willis Eschenbach published “Planet-Sized Experiments – we’ve already done the 2°C test” One of the truths in that article was directed at this past weekend’s “climate strikes”, inspired by 16 year old Greta Thunberg.

First they came for the coal industry, now for oil and gas: West Australian EPA decides state must meet “Paris” alone — The Wentworth Report

First they came for the coal industry, now for oil and gas: West Australian EPA decides state must meet “Paris” alone, by Joanne Nova. Suddenly, with five minutes warning, Western Australia may be going it alone to meet Paris on behalf of Australia. Not because an elected government decided that, but because of five people […]

History of Climate and Overpopulation Alarms

For a great history of Climate Change and Population Control Alarms watch this video from realclimatescience.com and Steve Goddard’s Youtube channel by Tony Heller.  A little long but well worth watching.  All scares are politics, not science. The aim is socialist/communist control – control of population, economy, politics, every facet of your life.


  • The world is still not overpopulated.
  • Hunger is more about politics than scarcity. Modern agriculture can feed everyone.
  • The climate is always changing, but it is not dangerous. Warm is healthier than cold.
  • Carbon Dioxide (CO2) is plant food, and why earth is not one giant ball of ice.
  • Water vapor is a far stronger greenhouse gas than CO2.
  • Most of the greenhouse effect occurred in the distant past with an almost opaque blanket preventing heat loss to space. Any further increase in CO2 will have little to no effect.
  • Deserts and jungles are greening. Crop yields have increased 15 to 20% on average.
  • The oceans are not rising, except for 7 inches a century since the little Ice Age.
  • Ocean acidification is a myth. Oceans are buffered to maintain alkaline pH, not acid.
  • Storms, droughts, floods are not increasing in intensity or frequency.
  • Polar bears and other wildlife are thriving.
