Topic 5: Ecology & Evolution
A natural process that creates moderate temperatures on earth to which life has adapted.
Earth is about 30oC warmer than it would be without any greenhouse gases in the environment. This is needed to sustain life on earth.
Enhanced greenhouse effect
The concern that the activities of humans may be increasing the levels of carbon dioxide and other greenhouse gases (methane, oxides of nitrogen) in the atmosphere.
This may lead to increased global temperatures and climate change.
Why can’t scientist know what problems the Greenhouse effect will cause?
However, it is possible to hypothesize about the general effects:
