Climate Science

  

    

I have been a Climate Change skeptic but now, after reading M.J. Sangster’s, The Real Inconvenient Truth,  a 2018 book on all the factors that make up the Earth’s climate, I now accept the opprobrious label of Climate Change Denier (CCD). It is not that I deny that the Earth might be in a warming phase, or that the CO2 level in the atmosphere has been increasing over the last 100 years. 

But in Sangster’s extremely well-researched book, he demonstrates that human-caused CO2, is a tiny fraction of the CO2 produced by nature, and that it makes up an  even tinier fraction of Greenhouse gases (GHG) which are 95% water vapor. In other words, human caused CO2, is little more than a drop in the vast ocean that is our atmosphere. Despite the claims of Climate Change Alarmists (CCA), Carbon Dioxide (CO2), human-caused or natural, is not poisoning the planet. Here are some facts from Sangster’s book.

 

“Carbon dioxide  (CO2) is not a toxic gas; it plays a vital role in plant and animal processes, including photosynthesis [CO2+sunlight+Water produces Plant food (carbohydrates) + Oxygen). Obviously, we need the oxygen, and plants need the carbohydrates.” … [199]

“That CO2 is directly correlated with temperature is not the issue however, the issue is whether or not the relationship is the dominate climate driver in the presence of other natural events and feedbacks, and clearly it is not or, as CO2 increases linearly, so too would temperature… It is just one climate forcing event in a complex Earth system… “[198]

 

The major factors in the complex Earth climate system are the Sun, Tectonics, Wind and Ocean Circulation, Oceanic Oscillations, Clouds and Aerosols, and Greenhouse Gases.  Sangster devotes a chapter to each of these factors and they are must reads for anyone really interested in following the science. Actually, his book is a fascinating introduction to Earth science. Did you know, for example:

That the Sun revolves in a relatively circular orbit around the nucleus of our galaxy at a speed of over 500,000 miles per hour. It takes 11 Earth years to complete its immense orbit, and drags us along with it although we don’t feel a thing. On route, we pass through fields of cosmic rays that bombard us. Our atmosphere protects us, but these cosmic rays still effect our climate. 

That the plate tectonics that formed our continents is still going on and generating vast amounts of energy. They also create mountain ranges. Did you know that 85% of the Earth’s volcanos are below the surface of the oceans?

That wind and Ocean circulation is a major factor in our climate. Without the warm waters of the tropical Gulf Stream, Northern Europe would be uninhabitable.

That clouds play a key role in regulating our climate. Some let in needed heat from the Sun, while others reflect it back into space. As noted above, water vapor makes up 95% of the greenhouse gas that keeps heat in, and that prevents the entire planet from looking like Antarctica. Sangster quotes former President Obama’s Science Czar, Dr, John Holdren: “a 1% increase in cloud cover would decrease the surface temperature by .8 degree C., the entire warming amount attributed to CO2 since the start of the Industrial Age.” [196]

That water vapor makes up 99% of the greenhouse gases that help regulate our climate, and that it is entirely natural. There is nothing we can do about it this fact, or any of the other facts noted above. 

Finally, Sangster points out a basic truth: “Earth is the only planet in the solar system with an atmosphere that can sustain life. The blanket of atmospheric gases not only contains the air we breathe but also modulates the energy balance… “[197].

I have limited this post to Climate Science. The rest of “The Real Inconvenient Truth” deals with the politics of Climate Science. We will deal with that in subsequent posts, but for now I will just say that it appears to me that it is the height of hubris to think that humans can combat the vast and powerful natural forces that have shaped our Earth on its incredible journey through space and time.
