The livestock sector requires a significant amount of natural resources and has an important role in global greenhouse gas emissions. The most important greenhouse gases from animal agriculture are methane and nitrous oxide. Mitigation strategies aimed at reducing the emission intensity of this sector are needed to meet the increasing demand for livestock products driven by population growth.

In simplest terms, "greenhouse gases" let sunlight through to the earth's surface while trapping "outbound" radiation. This alters the radiative balance of the earth see Figure A. The greenhouse gases in the atmosphere act in much the same way as the glass panels of a greenhouse, which allow sunlight through and trap heat inside. The panel refers to warming due to increased atmospheric concentrations of greenhouse gases as "greenhouse warming. The solar radiation is set at percent; all other values are in relation to it.
Larger image to save or print Gases that trap heat in the atmosphere are called greenhouse gases. This section provides information on emissions and removals of the main greenhouse gases to and from the atmosphere. For more information on the other climate forcers, such as black carbon , please visit the Climate Change Indicators: Climate Forcing page. A million metric tons is equal to about 2. For comparison, a small car is likely to weigh a little more than 1 metric ton. Thus, a million metric tons is roughly the same mass as 1 million small cars!

Methane CH 4 is a hydrocarbon that is the primary component of natural gas and a very potent and important greenhouse gas GHG. Unlike other GHGs, methane can be converted to usable energy. Capturing and using methane offers opportunities to generate new sources of clean energy and mitigate global climate change. Like emissions of other GHGs, emissions of methane due to human activities anthropogenic emissions have increased markedly since pre-industrial times. The global atmospheric concentration of methane has grown from a preindustrial value of about parts per billion ppb to 1, ppb in — a nearly percent rise and far above the natural range of the last , years.

Greenhouse gases GHGs warm the Earth by absorbing energy and slowing the rate at which the energy escapes to space; they act like a blanket insulating the Earth. Different GHGs can have different effects on the Earth's warming. Two key ways in which these gases differ from each other are their ability to absorb energy their "radiative efficiency" , and how long they stay in the atmosphere also known as their "lifetime". Specifically, it is a measure of how much energy the emissions of 1 ton of a gas will absorb over a given period of time, relative to the emissions of 1 ton of carbon dioxide CO 2.
Atmospheric methane is the methane present in Earth's atmosphere. Atmospheric methane is rising. The year global warming potential of methane is Early in the Earth's history carbon dioxide and methane likely produced a greenhouse effect. The carbon dioxide would have been produced by volcanoes and the methane by early microbes.
