Summary of PhD author Markus Ott: “Dismantling The CO2 Hoax” | Tom Nelson Podcast #78

00:00:00 - 00:30:00

PhD author Markus Ott challenges the premises of the man-made global warming theory, stating that the increasing concentrations of CO2 in the atmosphere are not solely caused by human activities and that there is no dangerous atmospheric greenhouse effect. He argues that cheaper methods to measure CO2 concentrations in the air exist and that examining plant remains is a more reliable alternative to ice core measurements. Additionally, Ott discusses the solubility of CO2 in water and its dependence on temperature, suggesting that changes in ocean temperature are likely responsible for the rise in CO2 concentration in the atmosphere. He also presents a graph indicating that political decisions such as lockdowns have had no impact on CO2 increase.

• 00:00:00 In this section, Markus Ott challenges the claims that pre-industrial CO2 was steady at 280 parts per million and that humans are solely responsible for the increase in CO2 since 1850. He presents evidence of climate change in his village, such as the remains of the ice age and the erosion channel and terraces, which farmers believe were constructed during a time of warm and dry weather to stop rainwater from flowing away and preserve humidity for crops. Additionally, Ott discusses the excavation of a station that dates back to the early Romans and the oldest streets in the area, indicating that the area has been continuously used for thousands of years.
• 00:05:00 In this section, PhD author Markus Ott discusses the main premises of the man-made global warming theory. He explains that the two main premises are that the steady increasing concentrations of CO2 in the atmosphere are caused by human activities and that there is an atmospheric greenhouse effect causing dangerous warming. He goes on to refute both of these premises, stating that they are not correct. He also mentions cheaper methods to measure CO2 concentrations in the air and that the margin of error for such methods is low.
• 00:10:00 In this section, Markus Ott discusses the issues with CO2 measurements in ice cores. He explains that the late 1800s measurements did not fit with the industrial era measurements, so some 18 years were cut out and the values were pushed together to fit the narrative of the CO2 hoax. Ott argues that the air bubble explanation for CO2 concentration is unreliable, and that examining plant remains is a more promising alternative method. By determining the density of openings in plant stomata and correlating it to the CO2 concentration of the environment, a reconstructed CO2 concentration shows much more variation than what is seen in ice core data.
• 00:15:00 In this section, PhD author Markus Ott explains the biases involved in analyzing CO2 concentrations in ice cores, including the migration of CO2 in ice bubbles and the impact of drilling techniques on the samples. He also examines the effect of human activity on CO2 levels in the atmosphere, citing research that suggests the increase in atmospheric CO2 is not primarily due to human emissions. Ott goes further to discuss the basic chemistry and thermodynamics of CO2 to explain these results.
• 00:20:00 In this section, PhD author Markus Ott discusses the solubility of CO2 in water and its dependence on temperature. He explains that CO2 is approximately 50 times more concentrated in the oceans than in the atmosphere. The speed at which CO2 goes into and out of the water is in equilibrium, but depends on temperature. Low temperatures make CO2 more soluble, so warming of the oceans could cause a higher CO2 concentration in the air. Additionally, deep sea vents exist that emit pure CO2, and their origin is not entirely known. Pierz Corbyn's hypothesis is that melting ice in high latitudes releases CO2 that is then transported by ocean currents to warmer areas of the earth.
• 00:25:00 In this section, PhD author Markus Ott discusses the slow transport of CO2 from the Arctic to warm oceans, which fits well with the hypothesis of the medieval warm period and the observation of Mariselsby. He also explains that human emissions have no measurable influence on the increase of CO2 concentration in the Earth's atmosphere and that changes in the temperature of the oceans are likely responsible for the rise. The lack of time resolution in some graphs has led to the claim that CO2 causes the increase of temperature, but with high-resolution ice core data, this hypothesis should no longer be considered valid.
• 00:30:00 In this section, PhD author Markus Ott discusses the questionable nature of pre-industrial CO2 concentration data and presents a graph that shows political decisions such as lockdowns have had no impact on CO2 increase.
