How to Fight Climate Change with Bacteria and Oxygen Climate change is one of the most urgent challenges facing humanity today. It is caused by the accumulation of greenhouse gases, such as carbon dioxide and methane, in the atmosphere. These gases trap heat and raise the average temperature of the planet, leading to melting ice caps, rising sea levels, extreme weather events, and loss of biodiversity. One of the ways to combat climate change is to reduce the emissions of greenhouse gases, especially from burning fossil fuels. However, this may not be enough to prevent the worst effects of global warming. We also need to find ways to remove the excess greenhouse gases from the atmosphere and restore the natural balance of the Earth's climate system. In this blog post, I will explore two possible solutions that involve using bacteria and oxygen to reduce the levels of methane and ozone layer depletion in the atmosphere. These are examples of geoengineering, which is the intentional manipulation of the Earth's environment to control climate change. Geoengineering is a controversial topic, as it may have unintended consequences and ethical implications. However, some scientists argue that it may be necessary as a last resort if other mitigation measures fail. Wildfire Prevention and Methane Reduction with Purple Sulphur Bacteria Methane is a potent greenhouse gas that has a warming effect 28 times greater than carbon dioxide over a 100-year period. It is produced by natural sources, such as wetlands, termites, and volcanoes, as well as human activities, such as agriculture, landfills, and fossil fuel extraction. Methane has a relatively short lifespan in the atmosphere, as it reacts with hydroxyl radicals (OH) and breaks down into carbon dioxide and water. However, the concentration of methane in the atmosphere has more than doubled since the pre-industrial era, and it is currently responsible for about 20% of the human-induced radiative forcing. One of the ways to reduce methane excess is to prevent wildfires. Carbon monoxide from wildfires make hydroxyl radical more scarce, which impact on methane concentration in atmosphere. On one hand, we need to prevent wildfires, on the other hand we could try to enrich upper atmosphere in oxygen in polar regions when polar jet help build ozone layer. ' Wildfires are becoming more frequent and intense due to climate change, droughts, and human activities. They not only release greenhouse gases, but also destroy forests and vegetation that act as carbon sinks. One possible solution to prevent high concentration of methane is to use purple sulphur bacteria (PSB), which are photosynthetic microorganisms that live in aquatic environments. PSB can use hydrogen sulphide (H2S), which is a flammable gas that often leaks from oil and gas wells, as an electron donor for photosynthesis. By doing so, they can convert H2S into sulphur, which is a non-flammable solid that can be used as a fertilizer. PSB can also produce organic matter that can feed other organisms and increase the biodiversity of aquatic ecosystems. By using PSB to consume H2S from oil and gas wells, we can reduce the risk of fire and explosion, as well as lower the emissions of methane and other greenhouse gases. This could also improve air quality and human health in areas affected by oil and gas production. However, this solution would require further research and development to ensure its feasibility, safety, and efficiency. Methanotrophs are bacteria that can use methane in their biological processes. They can lower atmospheric methane emissions, remove nitrogen in environmental and wastewater treatment systems, and even transform organic pollutants in soils 1. However, the use of methanotrophs to prevent the emission of methane from permafrost is still in the research phase. A study conducted by the University of Gothenburg demonstrated that when thawed soil dries up, emissions can decline instead of increasing 2. Another study found that changes in plant cover could limit emissions from melting permafrost, but if rainfall increases as temperatures rise, that could prevent soil from drying out, leaving wet-loving grasses to convey methane to the atmosphere 3. While the use of methanotrophs to prevent the emission of methane from permafrost is still in the research phase, it is a promising area of study that could have significant environmental benefits in the future. Ozone Layer Restoration and OH Production with Oxygen Spraying Ozone is a molecule composed of three oxygen atoms (O3) that forms a layer in the stratosphere, about 15 to 35 kilometers above the Earth's surface. The ozone layer protects life on Earth from harmful ultraviolet (UV) radiation from the Sun, which can cause skin cancer, cataracts, and damage to crops and ecosystems. However, the ozone layer has been depleted by human-made chemicals, such as chlorofluorocarbons (CFCs), which break down ozone molecules into oxygen atoms (O) and chlorine atoms (Cl). Although the production of CFCs has been banned by international agreements since 1987, their effects will persist for decades due to their long lifespan in the atmosphere. According to my own observations, there is a link between Climate Change and ozone depletion climate-change-and-ozone-layer.html One of the ways to restore the ozone layer is to spray oxygen (O2) into the upper troposphere, where it can react with UV radiation and form ozone molecules. This could also increase the production of hydroxyl radicals (OH), which are highly reactive molecules that can remove methane and other pollutants from the atmosphere. OH are formed by the photolysis of water vapour (H2O) in the presence of ozone. OH are short-lived in the atmosphere, as they quickly react with other molecules and form water vapour again. One possible method to spray oxygen into the upper troposphere is to use electric planes that can fly at high altitudes without emitting greenhouse gases or pollutants. These planes could be powered by renewable energy sources, such as solar or wind power. They could also take advantage of the polar jet stream, which is a fast-moving air current that circulates around the poles. The polar jet stream could help disperse the oxygen over large areas and enhance its mixing with other atmospheric components. By spraying oxygen into the upper troposphere, we could boost the formation of ozone and OH, which could reduce the levels of methane and other greenhouse gases in the atmosphere. This could also lower the global mean temperature and slow down the rate of climate change. However, this solution would also require further research and development to ensure its feasibility, safety, and efficiency. Oxygen can be derived from water by electrolysis of water. Electrolysis of water is a process that uses electricity to split water into hydrogen and oxygen gas by electrolysis 1. The process involves passing an electric current through water, which causes the water molecules to break down into hydrogen and oxygen gas 1. The hydrogen gas produced in this way can be used as hydrogen fuel, but must be kept apart from the oxygen as the mixture would be extremely explosive 1. The process of water electrolysis requires a minimum potential difference of 1.23 volts, although at that voltage external heat is also required. Typically 1.5 volts is required 1. Electrolysis is rare in industrial applications since hydrogen can be produced less expensively from fossil fuels 1.
