Greenhouse gases (GHG)

Gaseous constituents of the atmosphere, from natural or anthropic sources, that absorb and re-emit infrared radiation. The UNFCCC and Kyoto Protocol count for carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), and sulfur hexafluoride (SF₆), accompanied by two families of gases – hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) .

Diffusion in the oceans

The process through which the atmosphere and water continuously exchange molecules of carbon dioxide. The diffusion of carbon dioxide into the oceans accounts for almost half of the carbon extracted from the atmosphere. The colder oceans absorb more CO2 than warmer...

Albedo

The proportions of solar radiation reflected by a surface or object, expressed in percentage. Snow-covered surfaces have high albedo level; ground (soil) albedo can be high or low; vegetation-covered surfaces and oceans have low albedo level. The Earth’s albedo...

Avoided deforestation

It is the reduction in deforestation rate of an area, so that the resulting deforestation rate is lower than in a non-intervention scenario to decrease the forest conversion process.
