Debunking the myths about the cause of climate change

Scientific energy balance calculations confirm "Human-Caused Climate Change", but suggest greenhouse gases are NOT its primary cause. _Click for access on Amazon

The author, drawing on his expertise in calculating heating and cooling loads for home comfort, applies this methodology to a global energy budget analysis.

His scientific calculations conclude that Greenhouse Gases (GHGs) or CO2 are not the primary cause of global warming. Instead, the book asserts that the main driver is the widespread use of dark, low-albedo fossil fuel byproduct materials to modify the Earth's surface since the industrial revolution.

The scientific findings highlight the urgency of the climate crisis. The author issues a grave warning: continuing to focus on CO2 emissions—presented as a theory without verification—while failing to genuinely act to reduce solar radiation energy absorption will soon pose an existential threat to humanity.

The book ultimately concludes that construction and solar professionals hold a vital role in combating climate change. The effective solutions for reversing global warming are also provided in the book.

Authored by the sole inventor with three patents, this book introduces the groundbreaking Solar Charge Maximizing Controller (SCMC). The SCMC revolutionizes PV energy harvesting by eliminating common issues like overheating and power transmission loss, maximizing solar energy output in both grid-supported and off-grid systems.

The guide starts with SCMC fundamentals, followed by detailed system design and installation techniques, made easy to grasp with clear diagrams and pictures.

SCMCs are a powerful tool against Climate Change. They generate sufficient PV energy to charge electric vehicles, enabling on-site PV power use. SCMCs allow solar panels to be installed over low-albedo surfaces like asphalt and coal-tar pavement, minimizing solar irradiance absorption to cool the earth.

This essential guide is written for a wide audience, including solar professionals, contractors, hobbyists, and all renewable energy educators, engineers, technicians, and students.

Debunking the myths about the cause of climate change

Wayne Xue is the author of the book that debunks the myths about the cause of climate change. The excel calculation in the book confirms that the Greenhouse Effect may have a maximum 25% contribution to global warming, if there were any GHG effect at all. 

Myth #1: The greenhouse gas emission from human activity since the industrial revolution has caused global warming.

It is a fact that the CO2 level in the air has increased from 280 ppm to 430 ppm since the industrial revolution.  It is true that CO2 emission results in air pollution and poor air quality. But, it is also true that humans have been benefiting  from the increased CO2 level to support the needs of food consumption for over 8 bn world population currently worldwide.

Fossil fuel burning must be limited and reduced, but CO2 or GHGs are not the primary cause of climate change.

There are tons of Scientific Paper claims that CO2 level increase is the direct & primary cause of climate change, so they call CO2 a greenhouse gas (GHG), along with others such as methane (CH4), water vapor (H2O), and CFCs …etc.  But none of these claims had any scientific evidence to support, except that water vapor content has increased due to the temperature rise. None of the terms, such as “radiative forcing, climate sensitivity”…etc. they forged have any scientific merit. None of these claims are based on scientific calculation. The Radiative Forcing numbers (Watt per square meter) from CO2 or GHGs are also coming from the models they built, and the numbers vary from different models. So far, none of those models have predicted temperature increase correctly.

Climate Scientists built all the models by ignoring the fact that humans have been covering the earth’s surface with lower albedo materials from the fossil fuel byproducts since the industrial revolution. The pace of earth surface modification matches the CO2 level increasing. CO2 is the suspect who has been wrongfully accused since 1970’s, but was never convicted. The whole world has been led to bark up the wrong tree for decades, while letting the real crimes go by to cause disasters after disasters, to threaten humanity's existence with climate change.

The arthur of the following book performed the quantified calculation of earth’s energy budget and predicted further temperature increase, if no correct measures will be taken. The excel spreadsheet calculated exactly how much energy has been deposited in the oceans, and the earth has to be at what temperature to reach a balance point.

Debunking the myths about the cause of climate change

Myth #2: The greenhouse gases (GHGs) work as thermal blankets to keep the earth warm, and they are the main cause of global warming.

The climate scientists who believe in the theory of greenhouse gas, claim that GHGs work as thermal blankets to keep the earth warm. They further claim that the earth would be a freezing ball without GHGs. They claim it is CO2 that keeps the earth’s average temperature at present level.

They are making such claims by ignoring the fact that the earth’s temperature is not regulated by the CO2 level. It is a fact that the earth’s temperature is actually regulated by the thermal radiation energy it receives from the Sun, and the energy the earth rejects to space based on Stefan Boltzmann Law.

It is obvious that the earth's seasonal change is caused by the Summer and Winter Solstice due to the tilting of the earth. That is the very reason we have winter in the northern hemisphere, while summer in the southern hemisphere due to the tilting of the earth.  The CO2 level remains almost constant throughout the seasons with minor changes due to plant growth consuming CO2. Also, the south pole and north pole are cold while having the same CO2 levels.

The annual additional energy gain for the earth is over 50 Millions Tarawatt Hours to cause global warming at a current pace. There is no scientific basis of evidence that the energy gain has been caused by the additional 150 ppm of CO2 level increase since the industrial revolution.

The earth energy gain to cause global warming is calculated and summarized on page 30 of “the Causes and the Solutions” book. 

Nitrogen (N2) has a specific heat at constant pressure (Cp) of roughly 1.04 kJ/kg·K, while Carbon Dioxide (CO2) is around 0.84-0.85 kJ/kg·K. The specific heat content of Nitrogen (N2) is 22.3% higher than CO2. Nitrogen would have a better capacity to absorb the solar radiation heat during the days and release heat at nights to keep the earth warm than Carbon Dioxide (CO2) has. This is pure physics and science. There is no scientific basis of evidence to blame 0.043% of CO2 for causing global warming.  

Yes, water vapour has much higher specific heat content of approximately 1.9-2.0 kJ/kg·K, The moisture content in the air has higher capacity to store heat. However, water vapor (cloud) is not the cause, it is the result of high temperature due to the additional solar radiation energy that the earth received from the sun since the industrial revolution. Because humans modified the earth surface to receive more solar radiation energy and deposited it in the oceans since the “REVOLUTION”.

The air has to hold more moisture at higher temperature, based on the psychrometric chart that is also explained in the “the Causes and the Solutions” book.

“Minimizing solar radiation energy absorption & energy deposit in the air and in the oceans” is the only way to cool down the earth.

Myth #3: The high CO2 content on Venus is the primary cause of its extreme heat, creating a runaway greenhouse effect that traps solar energy.

The CO2 content on Mars is similar to the CO2 content on Venus, around 95~96%. Unlike Venus, which has an average surface temperature of about 464°C (867°F), Mars has an average temperature of -62°C (-80°F). There is no runaway greenhouse effect on Mars.

In fact, the high temperature on Venus is caused by the high atmospheric pressure on Venus. Its pressure is about 92-93 atmospheres (atm). The dense gas on the surface of Venus prevents the energy absorbed by Venus from emitting directly from the solid surface of Venus to space. Based on the ideal gas law of PV/T constant, the temperature has to increase due to the pressure increase.

On Venus, the high density and high pressure of the Venus atmosphere make it largely opaque to thermal infrared radiation. The Venus temperature would be even higher if Venus atmosphere contained Nitrogen or Oxygen mainly at high pressure, because their emissivities are even lower.

The earth’s surface has an emissivity of 0.6~1.0, while the CO2’s emissivity could be as low as 0.002. Venus and earth are similar in size, but Venus’s surface, consisting mainly of CO2, has an emissivity less than 1% of the earth’s surface emissivity. Based on the Stefan Boltzmann Law, Venus has no option, but to raise its temperature to reject the heat to the space it absorbs. It has nothing to do with greenhouse gas or radiative forcing.

The details of  Stefan Boltzmann Law calculation are explained in the book below. It  is available to read in Amazon through the link here:

<The Causes of Climate Change and the Solutions to Challenges>


Myth #4: Global warming is called “AGW” _Anthropogenic Global Warming, and there is nothing we could do. 

The term “AGW” was forged by some of the “climate scientists”, who have failed to find the real causes of global warming.  They could not explain why CO2 has been causing global warming, nor could they come up with any meaningful solutions to cool down the earth. They forged this term to blame everything on “Humans”. They also suggested removing CO2 from the air through the Carbon Dioxide Removal (CDR) or Direct Air Capture (DAC) process. Little did they understand that the CDR or DAC process will result in more additional energy being deposited into the oceans.

As a matter of fact, all of the CDR or DAR processes will deposit more additional energy into the air or the oceans, even if the power used for those processes comes from nuclear power plants. Similar to the power used for air conditioning equipment to cool down the buildings, all nuclear power plants have been depositing additional energy to the air or rivers that eventually end up in the oceans. It is the energy in the oceans that is slowing down or collapsing the AMOC (Atlantic Meridional Overturning Circulation) to cause climate change and climate catastrophes. Global warming has very little to do with the CO2 content in the air. The additional 150 ppm of CO2 in the air has nearly zero contribution to global warming!

Wayne's book quantifies all the factors that contribute to global warming.  The book also outlines the solutions.

The solutions must come from the building professionals, construction workers,  HVAC engineers, civil engineers, urban planners, architects and students. Once they understand how to minimize the solar radiation absorption, how to minimize the thermal energy absorption in the building materials during the day through their construction practice,  the earth temperature can be dropped to the pre-industrial level while still supporting current population and living standards!

The term "AGW" is misleading, and suggesting hopeless for humanity. It is true that human activity caused global warming, but there are lots we could do to reverse the trend. ENERPAK's solar charge maximizing controllers can harvest sufficient clean energy to support humanity, while cooling down the earth by covering all lower albedo materials to reduce the solar radiation energy absorption from the sun.

The Causes of Climate Change and The Solutions to Challenges

The book indicates that:

  1. Based on the earth’s temperature rise data collected since the industrial revolution, and the scientific calculation, as well as thermal dynamic analysis, the author of this book concluded that greenhouse gas emissions may only account for a maximum 25% of causes of the global warming, the major cause is from the  fossil fuel by-products that have been used to cover the surface of the earth, others include the excessive energy that humans have deposited in the oceans for over 100 years. 

  2. Humans have been using oceans as heat sinks to deposit excessive energy since the industrial revolution. Humans have set up the earth’s current condition for its temperature to reach an average of 18ºC if no actions are taken. Even if we stop greenhouse gas emission tomorrow and stop using fossil fuel by-products, the earth’s temperature will still rise at a pace of 0.0318 ºC (0.0572 ºF) each year, until it stabilizes at 18 ºC, when the earth will reject the same amount of energy into space as it will absorb. 

  3. To tackle this crisis that humanity has ever faced , the author of this book has come up with a concept called: “Global Warming Footprint Power” (GWFP). The GWFP has a unit of watts. GHG emissions can also be measured in GWFP. We can calculate the GWFP value for all the buildings, construction sites, parking lots, airport runways and pavement. We can also calculate the Global Warming Footprint Energy (GWFE) value in Kilowatt-hours.

  4. We may only cool down the earth, when the GWFP is written into the building codes, construction standards worldwide. This is the reason that we need lots of professionals, like you.
