Rich atmosphere, definition

The definite amount of greenhouse gases in the atmosphere has yet to be calculated. It depends on population, the per capita consumption of fossil fuel, deforestation, forestation activities and countermeasures that balance the extra carbon dioxide in the air. This could include planting more trees. Another factor is the use of alternative energy and conservation. Trades in fuel carbon will also have an effect. Transfers may occur from coal-rich to coal-poor nations. 

Despite the richness of the records, ice-core data alone can give only clues and not definitive answers concerning the mechanisms of the observed changes. This is because climate and atmospheric composition are multidimensional phenomena that cannot be adequately indexed by measurements from one or two regions. Changes in climate have distinctive spatial sig-...
