Lesson 13 - Atmospheric Pollution

• Another term for atmospheric pollution - Air pollution
• Greenhouse structure is commonly used in countries with cold temperature.
• Greenhouse structure is commonly made of what transparent material - Glass
• The greenhouse structure makes the temperature inside warm
• Most of the heat absorbed by greenhouse gases are radiated in all directions and cause warming of the Earth.
• Greenhouse is a structure with walls and roof made chiefly of transparent material, such as glass, in which plants requiring regulated climatic conditions are grown.
• The interior of a greenhouse exposed to sunlight becomes significantly warmer than the external temperature, protecting its contents in cold weather.
• The greenhouse effect happens because most of the heat is absorbed by greenhouse gases and then radiated in all directions, warming the Earth.
• A powerful greenhouse gas produced by soil cultivation practices, especially the use of organic fertilizers – Nitrous Oxide
• A hydrocarbon gas produced from manure of livestock – Methane
• Most important long-lived "forcing" of climate change – Carbon Dioxide
• The most abundant greenhouse gas that acts as a feedback to the climate – Water Vapor
• In water cycle, the process by which water vapor is formed – Evaporation
• In water cycle, the process by which clouds are formed – Condensation
• Released through natural processes such as respiration – Carbon Dioxide
• Gases that contributed to the greenhouse effect: Water Vapor (H2O), Nitrous Oxide (N2O), Carbon Dioxide (CO2), Methane (CH4)
• Water Vapor (H2O) - The most abundant greenhouse gas, but importantly, it acts as a feedback to the climate.
• Water vapor increases as the earth's atmosphere warms, but so does the possibility of clouds and precipitation, making these some of the most important feedback mechanisms to the greenhouse effect.
• A minor but very important component of the atmosphere, carbon dioxide is released through natural processes such as respiration and volcano eruptions and through human activities such as deforestation, land use changes, and burning fossil fuels.
• Humans have increased atmospheric CO₂ concentration by 47% since the industrial revolution began.
• Humans have increased atmospheric CO₂ concentration by 47% since the industrial revolution began.
• Humans have increased atmospheric CO₂ concentration by 47% since the industrial revolution began.
• This is the most important long-lived "forcing" of climate change - Carbon Dioxide (CO2)
• A hydrocarbon gas (which is Methane) produced both through natural sources and human activities, including the decomposition of wastes in landfills, agriculture, and especially rice cultivation, as well as ruminant digestion and manure management associated with domestic livestock.
• A powerful greenhouse gas produced by soil cultivation practices, especially the use of commercial and organic fertilizers, fossil fuel combustion, nitric acid production, and biomass burning - Nitrous Oxide (N2O)
• Atmospheric (air) Pollution - Refers to the release of pollutants into the air that are detrimental to human health and the planet as a whole
• Atmospheric (air) Pollution - The presence of toxic chemicals or compounds (including those of biological origin) in the air, at levels that pose a health risk
• Atmospheric (air) Pollution - The presence of chemicals or compounds in the air which are usually not present and which lower the quality of the air or cause detrimental changes to the quality of life (such as the damaging of the ozone layer or causing global warming)
• Scientists attribute the global warming trend observed since the mid 20th century to the human expansion of the "greenhouse effect"— warming that results when the atmosphere traps heat radiating from Earth toward space. 
• Certain gases in the atmosphere block heat from escaping. Long-lived gases that remain semi-permanently in the atmosphere and do not respond physically or chemically to changes in temperature are described as "forcing" climate change.
• Gases, such as water vapor, which respond physically or chemically to changes in temperature are seen as "feedbacks."
• Gases, such as water vapor, which respond physically or chemically to changes in temperature are seen as "feedbacks."
• Climate Change - Refers to the long-term alteration of temperature and typical weather patterns in a place.
• Climate change could refer to a particular location or the planet as a whole.
• Climate change may cause weather patterns to be less predictable.
• Climate change - These unexpected weather patterns can make it difficult to maintain and grow crops in regions that rely on farming because expected temperature and rainfall levels can no longer be relied on.
• Climate change has also been connected with other damaging weather events such as more frequent and more intense hurricanes, floods, downpours, and winter storms.
• Human activities, particularly the combustion of fossil fuels, are altering the climate system.
• Human-driven changes in land use and land cover such as deforestation, urbanization, and shifts in vegetation patterns also alter the climate, resulting in changes to the reflectivity of the Earth surface (albedo), emissions from burning forests, urban heat island effects and changes in the natural water cycle.
• Because the primary cause of recent global climate change is human, the solutions are also within the human domain.
