Greenhouse gas

Termites and cows account for much greenhouse gas.

Only two greenhouse gases get much attention.

Models of the climate system serve as the primary means for developing quantitative estimates of the effects of increasing atmospheric concentrations of carbon dioxide and other trace gases. Since increases in the concentrations of CO₂ and other "greenhouse" gases lead to changes in the radiation field, the treatment of radiative processes is the natural starting point for comparison of model studies.

CFC's are very efficient greenhouse gases. The addition of one molecule each of CFC-11 and CFC-12 gives a greenhouse warming of more than 10⁴ molecules of CO₂.

Biological scientists are aware that increased atmospheric carbon dioxide and trace gas concentrations would also have direct effects on plant growth as well as indirect effects through warming. […] Consideration of potential impacts must include the direct effects of "greenhouse" gas concentrations as well as climate warming.

Rapidly developing nations such as China and India are not required to reduce greenhouse gas emissions, despite their large and growing use of fossil fuels.

In other sectors, greenhouse gas emissions have fallen sharply. But transport emissions in the UK have declined by only 2% since 1990.

An example of information disclosure could be product labels that show the greenhouse gasses associated with an item’s production and use.

To keep the world within the 1.5°C temperature rise, the IPCC [Intergovernmental Panel on Climate Change] has recommended that by 2030, greenhouse gas emissions be cut to 45 per cent below the 2010 levels.

The consequences were catalogued by the Royal Commission for Environmental Pollution in 1994, which recommended several measures to constrain the emission of greenhouse gases.
