Document Summary
Global change increase in greenhouse gases in the atmosphere leading to warming. Accumulation of cfcs in the atmosphere impacting the ozone. Environmental degradation and deforestation are also associated with. Earth: a changing world changing faster today than throughout most of its history. : layer of gases enveloping the earth impacting the earth"s atmosphere, deforestation, and impacts on the earth"s oceans. Humans have generated local pollution since they developed agricultural societies. : easter island, process of deforestation led to the demise of the population 700 years ago. Having all of these technologies makes it more important and more global. The greenhouse effect solar radiation absorbed at the earth surface and reflected back in the form of long wave radiation some pierces through the atmosphere but a lot is trapped in the atmosphere contributing to the greenhouse effect. Natural processes: volcanic activity, decay of organic matter. Impacts on the ozone layer chemistry of the stratosphere has changed.
