ABCs of Climate Change
350 ppmv is considered to be the maximum amount of CO2 in the atmosphere in order to avoid a 2 degree rise in global temperature.
A tmosphere, which is warming up, thanks to the greenhouse gas effect of burning fossil fuels (and other practices).
Water vapour and carbon dioxide in the troposphere trap some of this heat, preventing it from escaping thus keep the Earth warm. This trapping of heat is called the "greenhouse effect".

A griculture, some aspects of which are potent causes of greenhouse gas emissions (see Methane).
A nthropocentrism, or Human-centredness, with consequent neglect of the needs of other species, ignorance of our dependence on them and our mutual interdependence.
A daptation, or measures to adapt to higher temperatures and other weather effects from climate change, as opposed to (or complementary to) Mitigation.
