Greenhouse Effect Essays: Examples, Topics, Titles, & Outlines
Greenhouse gases include carbon dioxide CO2methane CH4nitrous oxide N2Oozone O3essay on greenhouse effect, essay on greenhouse effect fluorinated gases. Biology, Earth Science, Ecology, Geography, Human Geography. The gases act like the glass walls of a greenhouse—thus the name, greenhouse gas. According to scientists, the average temperature of Earth would drop from 14˚C 57˚F to as low as —18˚C —0. Some greenhouse gases come from natural sources, for example, evaporation adds water vapor to the atmosphere. Animals and plants release carbon dioxide when they respire, or breathe. Methane is released naturally from decomposition. There is evidence that suggests methane is released in low-oxygen environmentssuch as swamps or landfills. Volcanoes —both on land and under the ocean —release greenhouse gases, so periods of high volcanic activity tend to be warmer.
Since the Industrial Revolution of the late s and early s, people have been releasing larger quantities of greenhouse gases into the atmosphere. That amount has skyrocketed in the essay on greenhouse effect century. Greenhouse gas emissions increased 70 percent between and Emissions of CO2, rose by about 80 percent during that time. The amount of CO2 in the atmosphere far exceeds the naturally occurring range seen during the lastyears. Most of the CO2 that people put into the atmosphere comes from burning fossil fuels. Cars, trucks, t rainsand planes all burn fossil fuels.
Many electric power plants do as well. Another way essay on greenhouse effect release CO2 into the atmosphere is by cutting down forestsbecause trees contain large amounts of carbon. People add methane to the atmosphere through livestock farming, landfills, and fossil fuel production such as coal mining and natural gas processing. Nitrous oxide comes from agriculture and fossil fuel burning. Fluorinated gases include chlorofluorocarbons CFCshydrochlorofluorocarbons HCFCsand hydrofluorocarbons HFCs. They are produced during the manufacturing of refrigeration and cooling products and through aerosols.
All of these human activities add greenhouse gases to the atmosphere. As the level of these gases rises, so does the temperature of Earth. The Greenhouse Effect and Climate Change Even slight increases in average global temperatures can have huge effects. Perhaps the biggest, most obvious effect is that glaciers and ice caps melt faster than usual. The meltwater drains into the oceans, essay on greenhouse effect, causing sea levels to rise. If all of this ice melted, sea levels would rise by about 70 meters feet.
The Intergovernmental Panel on Climate Change states that the global sea level rose about 1, essay on greenhouse effect. Rising sea levels cause flooding in coastal cities, which could displace millions of people in low-lying areas such as Bangladesh, the U. state of Florida, and the Netherlands. Millions more people in countries like Bolivia, Essay on greenhouse effect, and India depend on glacial meltwater for drinking, irrigationand hydroelectric power. Rapid loss of these glaciers would devastate those countries. Greenhouse gas emissions affect more than just temperature. Another effect involves changes in precipitationsuch as rain and snow. Over the course of the 20th century, essay on greenhouse effect, precipitation increased in eastern parts of North and South America, northern Europe, and northern and central Asia.
However, it has decreased in parts of Africa, the Mediterranean, and southern Asia. As climates change, so do the habitats for living things. Animals that are adapted to a certain climate may become threatened. Many human societies depend on predictable rain patterns in order to essay on greenhouse effect specific crops for food, clothing, and trade. If the climate of an area changes, the people who live there may no longer be able to grow the crops they depend on for survival. Some scientists also worry that tropical diseases will expand their ranges into what are now more temperate regions if the temperatures of those areas increase.
Most climate scientists agree that we must reduce the amount of greenhouse gases released into the atmosphere. Ways to do this, include:. Chlorofluorocarbons CFCs are the only greenhouse gases not created by nature. They are created through refrigeration and aerosol cans. CFCs, used mostly as refrigerants, are chemicals that were developed in the late 19th century and came into wide use in the midth century. Other greenhouse gases, such as carbon dioxide, are emitted by human activity, at an unnatural and unsustainable level, but the molecules do occur naturally in the Earth's atmosphere.
