The Truth about AGW aka Climate Change

The truth about Anthropogenic Global Warming aka Climate Change

The climate is changing as it always has.

The real question is

    • whether manmade Carbon Dioxide (CO2) is causing it,
    • whether it will have the dire consequences predicted and
    • whether we can or should do anything about it.
  • The earth has been warming since the Little Ice Age in the 18th century and has not reached the warmth of the Medieval Warm Period.
Recorded temperature throughout history (red) vs. IPCC model (blue)
  • Since the Little Ice Age, oceans have been rising steadily at 7 inches per century (<0.2 cm/yr.) and glaciers have been steadily receding with no recent acceleration.
  • Water, as vapor and clouds, is the major climate influence in the atmosphere. Water vapor can hold heat but also produces clouds that reflect heat back out into space. Precipitation from cooler high altitudes also helps in cooling.  More clouds, more cooling.
  • In the narrow band where CO2 absorbs heat reflected from the earth, it has already blocked the escape of most of the heat that it can. Increases in CO2 will have little or no effect on warming.
  • Warmer oceans hold less CO2 than cooler oceans, so warming causes off gassing. CO2 may be a trailing rather than a leading indicator of warming oceans and climate.
  • Plants use carbon dioxide for photosynthesis and give off oxygen. Animals use oxygen and exhale carbon dioxide.
  • Increasing from an assumed 280 ppm to 400 ppm (ppm = parts per million) is still a miniscule amount, but has increased plant growth rates so that forests and oceans have a greening effect that is visible from space.      (400ppm = 0.04%)
    • Greenhouses add CO2 by as much as 10 times normal to increase growth rates
  • During the Little Ice Age, the sun was quiet with no sunspots aka storms. This happened again around 1850 with a more modest cooling period. (Maunder Minimum and Dalton Minimum)
  • We appear to be entering a quiet period of the sun. That means a weaker solar wind so that more cosmic rays reach earth. Cosmic rays nucleate clouds. That means more clouds to cool the earth.
  • Other possible influences on climate include deviation of ocean currents, eg. Pacific Decadal Oscillation, which may be associated with more clouds, the wobbling (precession) of the earth’s axis and/or orbital eccentricity.
  • In Conclusion: CO2 is not the cause of recent warming.  None of the scary predicted consequences have materialized, and judging from history, are not likely to occur.  The climate is a very complex, poorly understood chaotic system.  Increased CO2 has been a boon to crops, forests and ocean plankton, and reducing CO2 would be harmful to plant life.
  • It is probably not possible to do anything about the current warming trend.

Perverted Truth Exposed: How Progressive Philosophy Has Corrupted Science[1]

by T Kiser (Author)

4.5 out of 5 stars 2 customer reviews on Amazon

In Perverted Truth Exposed, Kay Kiser exposes areas of science that have been corrupted by progressive and atheist philosophies disguised as science, including the theories of evolution, origin of life, cosmology, and quantum physics.

The climate change debate presents a modern example of how the perversion of science is politically imposed to support an anti-God, anti-human progress agenda of Marxist control and power while silencing opposition through intimidation. Kiser also answers:

Did Darwin really steal his theory of evolution from Alfred Wallace?

Why did Wallace later abandon the theory as not having sufficient evidence?

If Hubble discovered the expanding universe leading to the Big Bang Theory, why did he continually try to convince others that their conclusion was wrong?

Is man-made carbon dioxide causing global warming or is it a trailing indicator of climate change in a system dominated by solar cycles, cloud cover, and ocean currents?

[1] Excerpts from Amazon 11-9-2017

AGW Claims vs. Truth – Claim 10: World governments must take drastic action now to prevent catastrophic consequences.

Claim 10:  World governments must take drastic action now to prevent further warming and catastrophic consequences.

Truth:  The jury is still out as to whether warming is a good thing or a bad thing. More people die from cold weather-related events than from heat. Warming periods in the past such as the Medieval Warm Period were times of increased prosperity and peace. There is no indication that any sort of a tipping point is approaching that would cause the predicted catastrophic consequences. There has been no warming since 1998 and a possible cooling since 2005.

         It is not even certain that government action could have any effect on warming. If carbon dioxide is not the main cause of warming, then regulating it might be a fool’s errand. (See Claim 2.) Developed nations might curtail use of fossil fuels, but treaties proposed like Kyoto and Rio exempt developing countries. This includes China, India, and Mexico, among the largest and most industrialized developing countries in the world. Their output of carbon dioxide and pollutants from power plants and industry more than overpowers any gains from developed countries’ gains in efficiency or a change to “renewable” and “sustainable” solar and wind energy.

       Additionally, the money collected by the UN through these treaties is designated only for such unreliable energy development, not for improving the lives of impoverished peoples.  Improving the lives of these people would go much farther to protect the environment than any of these things. (Meanwhile, the development of over 200 hydroelectric dams in Africa have been prevented by activists within and outside the UN.)  People who have to worry about eating and feeding their families have no incentive to care for the environment.  Higher standards of living lead to more caring for the environment.

AGW Claims vs Truth – Claim 8: The world is in danger of catastrophic consequences – sea level rise, polar ice and glaciers melting, growing deserts, worse storms, droughts and floods

Claim 8: The world is in danger of catastrophic consequences of global warming such as sea level rise, polar ice and glaciers melting, growing deserts, worse storms, droughts and floods.

 Truth: a.) Sea levels have been rising along with warming since the Little Ice Age at an average rate of 7 inches per century due to glacier melting and expansion of seawater with warming. This rate has not changed significantly in recent times. To claim that sea levels have risen, the IPCC used a tide gauge in Hong Kong that showed tide levels rising, not because of sea level rising, but because the land is sinking (subsiding).  Those islands that were supposedly in danger of being swamped have had almost no net sea level rise in all the years since the early predictions. Globally, some land has been lost due to sea level rise and subsidence, but more land has been gained by other forces.

b.) Polar ice caps have shrunk and grown in recent years but overall they have remained relatively unchanged since preindustrial times. The media hype is about a theory that the Larsen Ice Shelf (in the more northerly Western Antarctica peninsula) might break away from Antarctica, causing rapid sea level rise of 5 meters (16.4 ft.). Although a part broke away in 1995, most experts say rapid collapse will not happen and any collapse and sea level rise would occur over centuries[2]. Both sea ice and ice cover have grown even more in other, more southerly locations on the continent. This year northern polar sea ice was thicker than usual so that there was some concern that the polar bears might have a harder time finding seals to eat. By the way, polar bear populations have been increasing in recent years.

c.) Glaciers have been receding since the Little Ice Age at a relatively steady pace that, along with water expansion with warming, accounts for much of the sea level rise. Melting of floating sea ice doesn’t cause a rising sea level. It is already displacing its weight in saltwater. Ice expands as it freezes, so that melt water shrinks as it melts, resulting in the release of the same weight of water as was originally displaced. Only land-based glaciers will have any effect on sea level. While most glaciers are receding, there are some that are actually growing.

d.) Droughts have not increased in recent times. Some years are worse than others, but the overall picture has not changed.

e.) Deserts are generally a result of geographic barriers and over grazing. Most of the Sahara Desert was once a grassy plain where livestock were grazed. It is a naturally dry area due to mountains to the west that block much of the moisture from the Atlantic Ocean. Overgrazing and loss of denuded top soil by winds had contributed to its expansion long before the industrial age. In most areas of the world, there has been no marked increase in the rate of desertification in recent times. Instead, deserts are greening as a result of higher CO2 levels that increase growth rates and make plants more tolerant of dry conditions by reducing the leaf pores. See previous post AGW Claims 2b The Benefits of Carbon Dioxide, answer c.

f.) Storms have not gotten worse. The dollar damages in some areas have increased due to increased urbanization, but not the severity of the storms themselves. The number of tornados has actually declined in the United States and their severity has not increased. The same is true of hurricanes and in recent years few have made landfall in the United States.

AGW Claims vs Truth – Claim 6. Temperatures are hotter than in the last 100,000 years

Global Temperatures 2500 BC to 2040 AD
Global Temperatures 2500 BC to 2040 AD

Claim 6. Temperatures are hotter now than they have been in the last 100,000 years

Truth: This is clearly an unsubstantiated myth meant to scare people into compliance with drastic environmental regulations.  The climate modelers have eliminated the Medieval Warm Period, which was hotter than it is today, and it was a time of prosperity. It was hotter in the 1930s than it is today. However, the American “Dust Bowl” of the 1930s was not due to warming. It was caused by opening up vast areas to farming that were poorly suited to it and a years-long severe drought. Based on historical accounts, ice cores and tree rings, modelers have dismissed the Medieval Warm Period and the Little Ice Age by claiming that they were not global phenomena but were limited to Europe and North America. More recent and more detailed ice core studies, etc. have shown that both of these periods were indeed global. Over the last 100,000 years, temperatures have been far hotter and far colder than the present.  Who can say what “normal” global temperature is when it is always changing?  Should we attempt to freeze the present day conditions as the ideal, or should we take a more reasonable approach to an ever changing climate?

AGW Claims vs. Truth – 4. Increased Fossil Fuel use and CO2 level

CO2 Increase since 1950 does not track Glacier Shortening
Increase in hydrocarbon use since 1950 does not change Glacier shortening rate since Little Ice Age (indicator of warming climate)

Claim 4. Manmade CO2 levels have been rising rapidly due to increased industrialization and populations since the 1950s.

Truth: CO2 levels have been steadily rising along with warming since the Little Ice Age. Recent increases in industrialization and population appear to have contributed to the increase in atmospheric CO2 since the 1950s when fossil fuel consumption began increasing. Rising temperatures have also contributed to increased CO2 because it is less soluble in warmer ocean water and is thus released.  it is unclear how much is from manmade sources and how much is from natural processes, but some estimate put it at 5%. However, if CO2 is not responsible for global warming, (see previous posts) increased levels shouldn’t alarm anyone and in fact increased CO2 should be celebrated as a plant growth promoter.

AGW Claims vs. Truth -3. Water Vapor Magnifies Warming from Carbon Dioxide

No hot spot - JoNova
Predicted hot spot from water vapor forcing is missing

Claim 3. Carbon dioxide is important because it has a forcing effect on other factors such as water vapor which magnify warming effects.

Truth: Since the atmospheric absorption of CO2 is already near saturation, (see previous post), very little additional heating can take place due to increased CO2. Contrary to AGW advocates, increased water vapor from warming doesn’t stay as vapor to trap heat near the surface. It forms low altitude clouds that strongly reflect solar heat back out into space, overwhelming any trapped re-radiation from the Earth and having an overall cooling effect. The models, which assume water vapor remains as vapor, predict an atmospheric “hot spot” at middle altitudes. Weather balloons and satellites have failed to find this assumed hot spot, which is the signature of atmospheric forcing of global warming in computer models. Due to low altitude clouds reflecting sunlight back into space, any feedback is negative (cooling), not positive (warming) as assumed in computer models.  For earlier posts, go to
