Greenhouse Gases |

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

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. It was largely the result of a 419-MMTCO2e drop in carbon dioxide (CO2) emissions (7.1 percent). There was a small increase of 7 MMTCO2e (0.9 percent) in methane (CH4) emissions, and an increase of 8 MMTCO2e (4.9 percent), based on partial data, in emissions of man-made gases with high global warming potentials (high-GWP gases). (Draft estimates for emissions of HFC and PFC substitutes for ozone-depleting substances in 2009 are included; 2008 data are used for emissions of other high-GWP gases.) Emissions of nitrous oxide (N2O), on the other hand, fell by 4 MMTCO2e (1.7 percent). The decrease in U.S. CO2emissions in 2009 resulted primarily from three fact...Get price

Carbon footprint - Wikipedia

BackgroundMeasuring Carbon FootprintsCarbon Footprints of Geographical AreasCarbon Footprints of Energy ConsumptionCarbon Footprints of TransportCarbon Footprints of ProductsCausesRise in Greenhouse Gas Over TimeReducing Carbon FootprintsSolutionsHuman activities are one of the main causes of greenhouse gas emissions. These increase the earthtemperature and are emitted from fossil fuel usage in electricity and other byproducts of manufacturing. The major effects of such practices mainly consist of climate changes, such as extreme precipitation and acidification and warming of oceans. Climate change has been occurring since the start of the Industrial Revolution in the 1820s. Due to humans' heavy reliance on fossil fuels, energy usage, and constant deforestation, the amount of greenhouse gas in the atmosphere is increasing, which makes reducing a greenhouse gas footprint harder to achieve. However, there are several ways to reduce onegreenhouse gas footprint, choosing more energy-efficient eating habits, using more energy efficient household appliances, increase usage of fuel efficientcars, and saving electricity.
