How to Discuss Global Warming with a “Climate Alarmist.” Scientific Talking Points to Win the Debate

Smoking Gun #1: Al Gore’s Ice Core CO2 Temperature Chart


Ironically, some of the most damning evidence again the AGW or Anthropogenic Global Warming Theory comes from Al Gore himself.

This post has been updated and reformatted since being published.

Talking Points:

  1. Climate change is the norm. Never in the 800,000-year ice core record is climate not changing.
  2. Four Temperature Peaks in the last 400,000 years were all above today’s temperatures and occurred at lower CO2 levels.
  3. Every ice-age began when CO2 was at or near peak levels, in other words, high CO2 levels were not enough to prevent ice ages.
  4. The current record high level of 400 parts per million(ppm) CO2, a full 33% above any previous level on the chart, has failed to carry temperatures to a record high.
  5. For any cause and effect relationship, the cause MUST lead the effect. CO2 does not lead Temperature, it follows it by 800 to 1,500 years. This video does an exhaustive review of the research. The AGW Theory is similar to claiming that lung cancer causes smoking. (Must Watch Video Clip)
  6. There is no mechanism defined that explains how or why CO2 would lead temperatures to pull the globe out of an ice age.
  7. There is no mechanism defined to explain how or why high levels of CO2 would trigger an ice age.
  8. The only defined mechanism by which CO2 can cause climate change is by trapping outgoing long-wave infrared (LWIR) radiation between the wavelengths of 13 and 18 microns. CO2 can only result in warming, there is no mechanism by which it can result in cooling. CO2 can only trap outgoing radiation, that is it.
  9. In the documentary “An Inconvenient Truth” Al Gore discusses how his classmate challenged the “consensus” of the continents never having been joined. The teacher mocked Al’s friend for challenging the “consensus.” The arrogant and close-minded teacher spouting the “consensus” view was wrong. Today, Al Gore and his fellow climate alarmists are acting like the closed-minded and very wrong Teacher. Albert Einstein, Christopher Columbus, Michelangelo, and Galileo aren’t remembered for agreeing with the “consensus,” they are remembered for shattering the “consensus.”

Smoking Gun #2: 600 Million Year Geologic Record


Talking Points:

  1. The current CO2 level of 400 ppm is at the extreme low end of the past 600 million years. Plants and therefore most life will die if CO2 falls below 180ppm.
  2. CO2 has been as high at 7,000 ppm, or 17.5x today’s level and the earth has NEVER in 600 million years experienced catastrophic global warming, NEVER.
  3. The earth fell into an ice age when the CO2 level was at 4,000 ppm, or 10x the level of today.
  4. Modern reefs and sea life developed over the past 220 million years when CO2 and temperatures were much higher than today. Coral Reefs only exist in the warm parts of the oceans and rely on dissolved CO2 to form their CaCO3 shells.
  5. There is no defined mechanism by which CO2 can allow the globe to cool, the only defined mechanism it to trap outgoing radiation between 13 and 18 microns.
  6. Over the past 600 million years, CO2 and Temperature simply aren’t correlated, and regardless of the level of CO2, temperatures cap out around 22 Degrees C.
  7. CO2 caused ocean acidification is simply not a possibility due to the huge buffering capabilities of the ocean, once again, the coral reefs developed during periods of much higher CO2 levels.

Smoking Gun #3: The IPCC Climate Models Fail…Miserably

Talking Points:

  1. Climate “science” is a “model” based science, its entire credibility is dependent upon the accuracy of its computer models. The very precise climate models are very inaccurate.
  2. The confidence of the climate science “consensus” increased as the climate models increasingly deviated from observations.
  3. 100% of IPCC Climate Models overestimated the expected increase in global temperatures, 100%. A 100% overestimation rate involving that many models represent a systemic bias, not a random error.
  4.   The climate models assume a linear relationship between CO2 and temperature. That relationship does not exist and will be covered in a later smoking gun.
  5. Real science relies on the scientific method, and reaches a conclusion through falsification (rejecting the null), experimentation, data collection, data analysis and reproduciblity. Climate “science” relies on none of the classical scientific practices, and relies on computer models, peer review and consensus. Albert Einstein isn’t remembered because he agreed with the “consensus,” he is remembered because he shattered the existing consensus.
  6. The extreme failure of the IPCC Climate Models to accurately model global temperatures means that the IPCC Modelers failed to include significant variables, failed to properly model CO2 or both. Regardless of which is true, the IPCC has failed on an epic scale to make the case that CO2 is the cause of the recent warming.
  7. If climate “science” was a “settled science,” the climate models would be able to accurately predict the climate. They don’t even come close.
  8. In real science if something is understood it can be modeled with great accuracy. Things fall at 9.8 m/sec^2 in a vacuum can be tested over and over and over again and the results will always be the same. If something isn’t understood, it can’t be modeled with any accuracy. If something really isn’t understood, the experts won’t even be able to agree on what is wrong with the models. The vast number of different and unique excuses (52 documented here) to explain why the models have performed so poorly proves just how little the expert climate “scientists” truly know.
  9. How can any real “science” have a “consensus” on something that they can’t even remotely model, and whose conclusions aren’t supported by empirical evidence/natural observation? Additionally, all these models passed “peer review,” and helped solidify the “consensus.”
  10. If this “science” is truly “settled” why are there so many different models with widely different results? The only thing that all the models seem to agree upon is that they are all wrong. I imagine that is because the most significant factors used in these models is CO2. To properly cure an illness, one must first properly diagnose it. Prescribing eyeglasses for headaches caused by a brain tumor will only lead to the death of the patient. Climate “scientists” can model CO2 and temperature all they want, the models will never be accurate.
  11. The climate models ignore significant factors like the Sun, Clouds and Water Vapor.
  12. Scott Adams of Dilbert fame even weighed in on this one.

Smoking Gun #4: There simply isn’t enough Anthropocentric CO2 to make a difference

Talking Points:

  1. OSU Stadium holds 100,000 Buckeye Fans and atmospheric CO2 is 400 ppm. If every Buckeye Fan represents one atmospheric molecule, then 40 Buckeye Fans would represent atmospheric CO2. Man however is not responsible for all the atmospheric CO2, and is responsible for at most 15 of those 40 molecules of CO2. Man’s contribution to atmospheric CO2 is the equivalent of 15 Buckeye Fans in OSU Stadium.
  2. CO2 is a trace gas at 400 ppm, and its contribution to global warming is to trap a very narrow band of outgoing radiation between 13 and 18 microns. Those wavelengths are consistent with a black body of temperature -80 degrees Celsius. More on this topic is covered in a later smoking gun.
  3. CO2 is 0.00004 or 0.04% of the atmosphere. Is it plausible that “activating” 1 out of every 2,500 molecules in the atmosphere can actually result in a material temperature change?
  4. Unfortunately, simple experiments to demonstrate even the basics of this “science” haven’t been properly run or even tried. What efforts have been attempted are complete jokes from the perspective of real science. Anthony Watts shows no mercy when he “peer reviews” Al Gore’s and Bill Nye’s effort to demonstrate the GHG effect of CO2. It is truly alarming how such foundational figures can’t even demonstrate even the basics of the “science” that they have manufactured and promoted at great tax-payer expense.
  5. Does it seem plausible that “thermalizing” 1 out of every 2,500 molecules can make a material difference upon the remaining 2,499? Especially when its energy if consistent with a black body of temperature -80 degrees Celsius?

Smoking Gun #5: Water Vapor is by far the most significant Green House Gas (GHG)

When discussing global warming with a climate alarmist, be sure to always tie things back to how CO2 could be the cause. The only defined mechanism by which CO2 can affect climate change is by trapping outgoing radiation between the wavelengths of 13 and 18 microns.

Talking Points:

  1. Incoming visible radiation has a wavelength between 0.4 and 0.7 microns and is consistent with a black body with a temperature around 5,200 degrees C (the Sun). CO2 is transparent to these wavelengths. (The importance of this will be addressed in a later Smoking Gun)
  2. The earth emits IR mostly between 6.5 and 12.5 microns, with a peak near 9.5 microns. 9.5 microns is consistent with a black body of temperature  18 degrees Celsius. CO2 is mostly transparent to those wavelengths.
  3. CO2’s absorbs between 13 and 18 microns, with a peak near 15 microns. Those wavelengths are consistent with a black body of temperature -80 degrees Celsius. CO2’s signature would be to cause warming in Antarctica, which is addressed in a later Smoking Gun.
  4. H2O is by far the most significant GHG, and absorbs across the IR Spectrum. Where there is water vapor in the atmosphere, there is warmth. The same can’t be said about CO2.
  5. CO2 absorbs a small fraction of the IR Spectrum having 3 narrow peaks at 2.7, 4.3 and 15 microns, all of which largely miss the peak outgoing  IR radiance of the earth at 9.5 microns.
  6. H2O largely absorbs the same IR spectrum as CO2, and is at much higher concentrations in the atmosphere. H2O IR absorption usually makes CO2 contribution to warming inconsequential.
  7. CO2 has changed from 0.0003 to 0.0004 over the past 100 years and absorbs a very very very small % of the outgoing radiation. H2O can change from 0.001 to 0.04 in a day and absorbs a vast majority of the outgoing IR spectrum. Neither H20 or CO2 have ever caused catastrophic warming of the globe.
  8. Given that the GHG effect only slows cooling, and can never actually “warm” the atmosphere, the dynamics of the GHG effect is to put in a temperature floor. If you notice from the above graphic, as the earth warms, it enters what is called an “atmospheric window” where little energy is trapped. As the earth cools, more and more of the outgoing wavelengths are trapped (note the near solid black to the right of 13 microns)
