Changes in the orbit of the Earth around the San. The reast elliptical orbit means higher levels of solar radiation and therefore higher average temperatures. The cyde eecers every 100,000 years
Product of organic material being decomposed. Animals significantly contribute to the global budget. Greenhouse effect is 30 times that of carbon dadde
The increase in the proportion of greenhouse gases in our annosphere due to human actions. This eats in the average temperature of the atrasphere increasing above what it would be naturally
The process of removing carbon dioxide from the combustion process so that the amount being released into the atrsssphere is reduced. The carbon is typically stored in the Ithasphere
