  • 00:00:00 In this section, Dr. Stuart Harris discusses the influence of heat on ecosystems, particularly as it relates to permafrost and global warming. His research in climatology and paleoclimatology, combined with his experience working with Russians and Chinese on permafrost research, has led him to the conclusion that heat is generated from the surface of the Earth and affects soil conditions. He talks about the importance of exploring Earth-Sun relationships and the development of models to have a better understanding of these relations, as well as the progress that has been made through the use of new weather stations, oceanographic research, and satellite measurements. He also contrasts and compares climatic theories and their support for each other.
  • 00:05:00 In this section, Stuart Harris discusses the role of water in climate change. According to him, 70% of the Earth's surface is covered by water, with only 30% consisting of land that absorbs heat. The reflectance of ice ranges from 0.5 to 0.7, meaning that ice and snow cover surfaces reflect back into space much of the incoming radiation. This results in less heat being absorbed at the Earth's surface. Transporting heat around the surface, dry air has low heat capacity, so it does not carry a significant amount of moisture. Warm ocean currents, on the other hand, carry large quantities of heat, but are constrained by the distribution of land and water. Antarctica, due to its circular shape, stops warm surface ocean currents from reaching the South Pole. Overall, the distribution of water affects the heat absorption and transport in the Earth's climate system.
  • 00:10:00 In this section, Stuart Harris discusses the movement of heat and currents across the globe, particularly the impact of the Gulf Stream. The Gulf Stream carries warm water and air northwards from the tropics, which heats up the Arctic Ocean and Europe. However, the Kuroshio Current in the Pacific bumps into meltwater from glaciers on the south coast of Alaska and gets deflected, preventing it from passing through the Bering Strait. As a result, cold air and ice form in the arctic, affecting the temperature in Europe. The primary source of cold dense Arctic air is in the interior of North Northeast Siberia, where it moves eastwards along three pathways, resulting in the formation of ice caps in North America during colder months. This movement is caused by the rotation of the Earth and is warmed by the Gulf Stream over the North Atlantic, resulting in warmer weather over Western Europe. The air also absorbs heat and moisture from the ocean, which causes it to form ice caps when it passes over Eastern Europe before heading towards Asia where it stagnates and calls to form the next lot of cold. The most important path is the one that comes across the Arctic and into the Hudson Bay Area, where it stagnates and affects primarily the temperatures in Ontario, Canada.
  • 00:15:00 In this section, Stuart Harris discusses how heat and moisture picked up by the Gulf Stream brings warm weather and rain to Western Europe, which gradually cools down as it moves into Siberia. The source of the cold air in Siberia comes from the ocean with sources of warm air masses centered on the zone of inter tropical convergence between the Tropics of Cancer and Capricorn where the sun is over directly overhead twice a year. The main sources of dry subtropical air are desert areas such as the Sahara in Africa, the Haryana Desert in India, and Northern Mexico in North America. The main moist sources of heat transport into the Northern Hemisphere are monsoons and typhoons, which occur mainly in the northern and eastern hemispheres, on the east side of continents, coming from the eastern part of Asia. The identification of cold areas on land is best known today from glaciers remaining from the last ice ages. A reasonable but incomplete record was obtained by plotting all the available dates of cold events on the history histogram, showing that there have been at least 13 cold events starting about 3.6 million years ago. For a more complete record, scientists have to go to the ocean and examine the sediments, which are full of plankton, allowing them to have a look at the climate record.
  • 00:20:00 In this section, Stuart Harris discusses the cyclical nature of climate change and how it has been affecting the Earth for the past 800,000 years. He explains that there have been 23 Ka-cycle cycles of glaciation, including similar recession cycles observed during the Milanich GS period. The cycles are alternating periods of cold and warm temperatures, and each cycle lasts for about 10,000 years, with interglacials separating them. The cycles have become more frequent due to the climate's natural oscillation, leading to an increase in the Earth's cooling over time. Harris also explains that the movement of heat is not always to the north, as previously believed. Instead, the evaporation of water and addition of heat to the air result in the Arctic water becoming heavier and sinking to the bottom of the ocean. This process leads to periodic cold currents flowing out from the Arctic, while a return current is established to keep the ocean flat or horizontal. The return flow carries cold Antarctic water into the North Atlantic, thereby transporting heat to the south and balancing the temperature fluctuations. However, this process cannot occur all the way to Antarctica due to the Halocline, which is a halo of cold water at the ocean's bottom.
  • 00:25:00 In this section, the speaker discusses the effects of carbon dioxide on the Earth's climate. The speaker explains that after a sudden drop in the atmospheric carbon dioxide levels, there was a glaciation period in South Africa, which caused a drop in temperature and a reduction in carbon monoxide in the air. However, the recovery in temperature was not followed by a complete recovery in carbon dioxide levels, and this drop has become more serious. The speaker also discusses the Intergovernmental Panel on Climate Change's (IPCC) hypothesis in 1988 that human activities, particularly the start of the Industrial Revolution, have led to an increase in atmospheric carbon dioxide levels, which has caused an increase in global temperatures. The speaker concludes that while carbon dioxide is a greenhouse gas, its effects are limited to a small range of the full long wave radiation emitted by the Earth, and it does not settle in high places, meaning that theories involving the formation of a layer in the stratosphere do not hold water.
  • 00:30:00 In this section, the speaker discusses the interaction between atmospheric carbon dioxide (CO2) and calcium ions in the sea during glaciations. When the temperature drops, CO2 becomes more soluble in water and reacts with calcium ions to form limestone, which is deposited. The process of decarbonization results in CO2 being absorbed into the ocean, leaving less gas for photosynthesis of plants. This also lowers atmospheric CO2 levels, making it difficult for plants to carry out photosynthesis.
  • 00:35:00 In this section of the video, Stuart Harris discusses the temperature changes that have occurred on Earth and the role of the Arctic in this process. He compares two periods of time, showing that there has been rapid warming in the Arctic, while other regions such as the Sahara, Australian Outback, Eastern China, and Germany show no obvious warming. Harris argues that this disagrees with the Intergovernmental Panel on Climate Change (IPC) and suggests that there is new data coming from Salt Lake City in Utah that shows that there has been a decrease in winter cold temperatures. He believes this indicates that the 23k U peak of warming may have ended about 2020 and that we are now heading towards another glaciation. Harris explains that the source area for the cold air mass that affects the Arctic is in Siberia, where there is a one summer and one winter, and warm air masses come in from the subtropics, leading to two peaks of heat in the summer.
  • 00:40:00 In this section of the video, the speaker is discussing the current cooling trend in tropical and subtropical air masses, which is causing an increase in summer values despite the solar position in its source area. This is due to the fact that the warm and cold sources are out of phase, and local factors such as El Niño will further modify these changes. The speaker also mentions that this change occurred around 2020 and had significant impacts on weather patterns, including extreme flooding events, droughts, and fires in Canada. In particular, the coldest temperatures recorded in Antarctica in 2018 have been linked to the warmest temperatures in the northern hemisphere. According to the speaker, if the next two climatic cycles continue to evolve as they did in the last location, Canada is likely to face more significant weather events in the future, including extensive snow and ice coverage.
  • 00:45:00 In this section of the video, Stuart Harris discusses the potential impact of climate change and the possibility of another glaciation occurring. He explains that while there is still time before an immediate impact is felt, there may be a need for humans to adjust to the changing environment. This may involve reductions in the population of Canada and challenges related to power sources, such as icing up of electric cables and hydrological reservoirs. Harris also discusses the limitations of nuclear power and the need to invest in backup renewable energy sources, such as coastal wave energy and wind power. Finally, he emphasizes the importance of carbon sequestration through photosynthesis and the need to maintain adequate levels of carbon dioxide in the atmosphere.
  • 00:50:00 In this section of the video, Stuart Harris discusses the significance of the changing climate on various aspects of life, including economics and the environment. He emphasizes the importance of adapting to these changes and using all available resources to cope with them. Harris also mentions the impact of carbon dioxide on the agricultural industry and how the tax on fertilizer and fuel affects the final price of goods. He argues that changes in the climate are undeniable and that we need to adjust to them in order to survive successfully. Harris also touches on the current debate over whether to transition to clean energy sources and the importance of understanding the natural cycle of cooling and warming events.
  • 00:55:00 In this section, Stuart Harris discusses the possibility of a global glaciation and its potential impact on the Earth's climate. According to Harris, the current climate conditions are relatively stable, and the Earth is not currently experiencing the worst of it. However, there are two upcoming papers that provide insight into the history of climate and the formation of the Earth's atmosphere. One of the papers deals specifically with photosynthesis and the continuation of life, while the other looks at the history of climate from the start of the Earth. Harris mentions that CO2 was not initially an original component of the atmosphere and that its presence was largely due to marine animals and the production of oxygen from iron ORS. Harris further mentions that his recent paper on the calculation of air around the Arctic has been widely read and that other papers in the range of 5,600 reads are also available for those interested in learning more.

In a recent YouTube video, retired IT distinguised engineer Stuart Harris discusses how global warming and climate change have become a topic of concern for him after a hiking trip with a CEO of a company. Harris goes on to explore the possible causes of climate change, including the spike in warmth in the UAH data and the possibility of other factors such as a giant asteroid impact. He also challenges the idea that humans are the primary cause of climate change, arguing that animals' chemical reactions with temperature changes play a crucial role in species diversity and extinction.

  • 01:00:00 In this section, Stuart Harris discusses how hiking with a CEO of a company led him to explore the issue of global warming and climate change. He notes that the tax negotiations they had sparked his interest, and he wanted to learn more about the connection between cold weather and the generation of CO2. Harris then delves into the recent spike in warmth in the UAH data, which some have speculated could be due to a volcanic eruption. According to Harris, while water vapor can have an effect on the atmosphere, its contribution is not critical compared to the movement of heat. He also discusses the possibility of other factors contributing to climate change, such as a giant asteroid impact. Harris concludes by stating that if the earth continues to warm up, it will require a significant shift in the species that support our bodies' chemical reactions.
  • 01:05:00 In this section, the speaker discusses the idea that species diversity has decreased since the Jurassic period due to climate change. He explains that chemical reactions between temperature changes and species can lead to changes in equilibrium, which can cause a species to go extinct if it cannot adapt quickly enough. He also mentions that like sharks, some species in a previous era may have been able to adapt to the conditions of the time, but large species like dinosaurs faced significant challenges such as needing a lot of food and living in semiarid environments with both floods and dry areas. The length of time each species lasted in the past is short compared to some of the species seen today. The speaker also notes that some dinosaurs had feathers, and that it is interesting that the people pushing the CO2 theory in the government may not have considered the anomalies that have been discovered.
  • 01:10:00 In this section, the speaker discusses the abandonment of the idea of planetary motion and the movement of the Earth, and the shift towards research into physical sciences and the close terrain sciences. The speaker suggests that the government was cutting down funding for these fields in the 1970s and 1980s, and that scientists were concerned about the lack of funding. The speaker goes on to discuss the Earth's warming and the lack of evidence of human contribution to this phenomenon. The speaker suggests that the abundance of radiation at higher latitudes can cause an increase in solar energy, and that the angle of the Earth also influences the amount of radiation received. The speaker then asks if atmospheric CO2 has risen from 280 PPM to 420 PPM since the 1800s and if the increase was caused by humans, and the speaker suggests that the contribution of humans is negligible.
  • 01:15:00 In this section, Stuart Harris discusses the impact of deforestation on surface temperature and how it is altering the global climate. He acknowledges the severity of the issue and suggests that people are working on it to mitigate its effects. Harris also thanks the listener for their time and expresses his hope to have a similar conversation again in the future.
