Greenhouse Effects Video: The greenhouse gasses are a layer surrounding the earth. Sun rays warm the earth. A part of the sun’s rays are absorbed by earth Another part is reflected into space The last part of the rays are trapped by the greenhouse gasses The trapped rays are what warm the earth The main greenhouse gasses are: Carbon Dioxide (CO2), Methane (CH4), and Nitrous Oxide (N20). The greenhouse gasses are like a nursery. In both, the sun's rays are trapped. Just like in a greenhouse, trapped sun rays can come in, but not come out. Without the greenhouse gasses, earth would be very cold Without them, we wouldn’t survive. The Passage: Water Vapor, Carbon Dioxide, and Methane, trap the rays to stop them from escaping. Without the greenhouse effect, earth would only be at 18 degrees celsius. Due to human activities, the greenhouse effect is warming the earth up, which is causing global warming. Carbon Dioxide is a naturally occurring gas. Carbon Dioxide made by humans is the biggest contributor to global warming. It accounts for 76% of global greenhouse emissions. The levels of Carbon Dioxide is increasing by the use of fossil fuels. Many forms of transportation use diesel and fuel, which contributes to global warming. Before, Carbon Dioxide had a delicate balance, now it doesn’t. Fluorinated gas makes up 2% of the emissions. This gas has no natural source. Hydrofluorocarbons can last up to 270 years in the atmosphere. Some perfluorocarbons can last up to 50,000 years Methane Emissions are somewhere around 16% They’re less than CD (Carbon Dioxide) emissions. Human activities raise the emissions of methane. Cattle, Sheep, and goats create manure The manure is then made into fertilizer which increases the emissions Nitrous oxide makes up about 6% of the emissions. Fertilizers are one of the most common sources of nitrous oxide. The nitrous oxide molecules can be found in plants, animals, micro organisms, and the soil. The molecules stay for about (An average) 114 years in the atmosphere. Nitrous oxide has 300 times more impact on global warming, which is more than carbon dioxide. To help stop creating the emissions, people should try to reduce the use of fossil fuels that they use. Shifting to renewable energy is something to think of New technology like electric cars and fuel-efficient can help reduce emissions We should also protect forests. Reducing food waste is another way to help. Video: Three solutions could reduce 269.02 gigatons of CO2e Since 1751 the world has emitted a total of 1500 gigatons of CO2 (This was in 2020) Refrigerant management is a solution to help stop climate change In 1987, 196 countries and the European Union ratified a protocol to phase out the use of chlorofluorocarbons Hydrofluorocarbons (HFCs) are created at home. HFCs have around 1,000 to 9,000 times the capacity to trap heat than CO2. HFC control could lessen climate change We could avoid 57.8 gigatons of CO2 in 2050 (90 years of no cars is equal to that) Solution two is onshore wind energy Denmark gets a lot of their energy from the wind 47% of Denmark’s power usage was from wind turbines in 2019 29% of that coming from onshore installation of the turbines. Turbines have small land footprints. Which means, farming, recreation, and conservation Researchers at Project Drawdown say that if we can use the wind capacity to 26% our global energy consumptions, we could avoid about 147 gigatons of co2e The world only uses 4% of wind energy Raising the amount of wind energy usage from 4% to 26% won’t be easy in 30 years We need to get more money and materials for the wind turbines The last solution is a plant based diet If we didn’t eat so much meat, we the transportation of the animals would go down If we eat a plant-rich diet, by 2050, we could avoid making 65.02 gigatons of co2e (+)
