What are gas emissions?

gas emissions are released into the atmosphere of gas materials, whether naturally or artificially. These gas emissions exist in various forms: especially water vapor, carbon dioxide, methane, nitrous oxide and ozone. Each of these substances, although they already exist in the atmosphere at certain levels, can be increased by different means, such as the burning of fossil fuels or eruption of the volcano. The effects of these gas emissions come in the form of a greenhouse effect. Each of these gases absorbs radiation in the atmosphere and raises the ground temperature. For example, methane is one of the strongest radiation absorbers, while there is no carbon dioxide. However, carbon dioxide levels from gas emissions are much more predominant than methane, so its effect is much stronger overall. This atmospheric warming is required to maintain the current conditions of the plan. Earth's surface temperature would be approximately 59 ° F (about 33 ° C) cooler if these gases were not present in the atmosphere.

Water vapor is the most common gas emissions on the planet and is the largest percentage of impact on the greenhouse effect. This is generally not caused by people in abundance. Two percent of the atmosphere consists of water vapor, including clouds, most of which stem from a simple gas emissions caused by evaporation. This percentage, according to the Environmental Health Center of the National Security Council, is 66 percent of the greenhouse effect.

Using samples of ice core, scientists have found that greenhouse gas emissions have changed over time. 500 million years ago, carbon dioxide levels were as predominant as it is today. High Concentrations of Greenhouse Gases Continumed Until The Modern Era. Humans now lives in the era of the Holocene, which began at the end of the last ice age for about 10,000 years. During this period, gas emissions remained from naturally occurring sources such as volcanoes, relatively stabilized, which represents only one percent of the atmosphere fluctuations.

Since 1750 However, gas emissions have increased significantly due to the onset of the industrial revolution. Before this time, carbon emissions were about 280 parts per million (PPM). Since then, this number has been steadily increasing to 387 ppm by the beginning of the 21st century. These greenhouse gas emissions come mainly from the combustion of fossil fuels, deforestation, chlorofluorocarbons used in cooling and fertilizer. Each of these culprits was focused at the end of the 20th and at the beginning of the 21st century by the "Green Movement", an effort to reduce carbon emissions.
