Compose a 1250 words assignment on the concentration of greenhouse gases in the atmosphere. Needs to be plagiarism free! If the heat from the sun is balanced by the same amount of heat flowing towards space, the earth can be said to be in a radiative equilibrium, and temperatures throughout the globe will become more stable.
Climatic changes have typically taken place on earth as a result of natural causes through timescales varying from decades to centuries, nonetheless, based on significance evidence, professionals in climatic science research agree that the changes that have been evident in the past few decades are large as a result of human activities. The influences of human beings on climate change come from the burning of fossil fuels as well as changes in the manner in which lands are utilized. These activities modify the radiative equilibrium of the planet through altering the composition of the atmosphere thereby increasing the effect of greenhouse gases or changing the degree of reflectivity of the surface of the earth.
Greenhouse gases enter the atmosphere through two distinct ways: natural processes such as respiration by plants and animals and through activities undertaken by human beings. The key sources of greenhouse gas emissions by human beings include the burning of fossil fuels, deforestation, usage of synthetic fertilizer, and numerous other industrial processes. Four key forms of greenhouse gases exist including methane, carbon dioxide, nitrous oxide, and gases that contain fluorine, bromine, and chlorine, with the main greenhouse gas that can be considered as feedback being water vapor. All these gases can continue to exist in the atmosphere for varied periods while at the same time impacting climate at various scales.
The lifespan of carbon dioxide, which is the most common greenhouse gas associated with the activities of man, in the air is possibly the most difficult to conclude since various processes remove it from the atmosphere.
