Greenhouse Gas Concentrations
EE Link EnviroInfo Environmental Information FOE Future Flight Geography World National Building Specification Think Energy Greenhouse Gas Concentrations The atmospheric concentration of a greenhouse gas is a measure of the abundance of that gas in air, usually defined in terms of the proportion of the total volume that it accounts for. Greenhouse gases are trace gases in the ...

CRU Information Sheet no. 7: Thermohaline circulation
Increased rainfall and warming over the North Atlantic are both expected as a result of increased greenhouse gas concentrations, and so it can be argued that global warming may cause a rapid collapse of the thermohaline circulation. The self-sustaining system described above is, however, much more complex in reality, and the more complete ...

Greenhouse Gas Emissions
In the last 200 years, mankind has been releasing substantial quantities of greenhouse gases into the atmosphere. These extra emissions are increasing greenhouse gas concentrations in the atmosphere, enhancing the natural greenhouse effect, which is believed to be causing global warming. While man-made greenhouse gases include carbon dioxide, methane and nitrous ...
