The decline in total emissions—from 6,983 million metric tons carbon dioxide equivalent (MMTCO2e) in 2008 to 6,576 MMTCO2e in 2009—was the largest since emissions have been tracked over the 1990-2009 time frame.

Global Greenhouse Gas Emissions Data | US EPA

Global Emissions by GasGlobal Emissions by Economic SectorTrends in Global EmissionsEmissions by CountryAt the global scale, the key greenhouse gases emitted by human activities are: 1. Carbon dioxide (CO2): Fossil fuel use is the primary source of CO2. CO2 can also be emitted from direct human-induced impacts on forestry and other land use, such as through deforestation, land clearing for agriculture, and degradation of soils. Likewise, land can also remove CO2from the atmosphere through reforestation, improvement of soils, and other activities. 2. Methane (CH4): Agricultural activities, waste management, energy use, and biomass burning all contribute to CH4emissions. 3. Nitrous oxide (N2O): Agricultural activities, such as fertilizer use, are the primary source of N2O emissions. Fossil fuel combustion also generates N2O. 4. Fluorinated gases (F-gases): Industrial processes, refrigeration, and the use of a variety of consumer products contribute to emissions of F-gases, which include hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (sf 6).

Climate change occurs due to an increase in greenhouse gases in the earth’s atmosphere. Greenhouse gases are the result of several human activities, particularly those that have taken place since the industrialization began. When these gases are emitted into the air, they work to trap solar energy in the atmosphere. This trapped energy turns into increased global temperatures. Since industrialization, carbon dioxide concentrations have increased, temperatures have increased by 1.7 Degrees Fahrenheit, polar ice caps have reduced in size by 13.3% per decade, and ice on land has reduced by 281 Gigatons per year. The effect that a greenhouse gas has on the environment depends on its lifespan, its global warming potential, and its amount. This article takes a look at some of the human activities that contribute to global warming.Get price

Greenhouse Gases | Encyclopedia.com

IntroductionHistorical Background and Scientific FoundationsBibliographyCertain gases in Earthatmosphere—particularly carbon dioxide (CO2), methane (CH4), and water vapor—trap energy from solar radiation and thus, keep Earth warmer than it would be otherwise. These gases are termed greenhouse gases and the warming they create is termed the greenhouse effect or greenhouse warming. About 65% of greenhouse warming is caused by CO2, the most abundant greenhouse gas. A certain amount of greenhouse warming occurs naturally; without it, Earth would be too cold to sustain most life. However, the intensity of the greenhouse effect is being increased by human activities that add greenhouse gases to the atmosphere. For example, burning fossil fuels (coal, petroleum, and natural gas) was adding over 6 billion metric tons of carbon dioxide to the atmosphere every year as of 2006, with world usage of such fuels increasing rapidly. About half of the CO2 released each year remains in the atmosphere and intensifies Earthnatural greenhouse effect; the rest is absor...Get price
