Greenhouse effect is the warming effect seen in a green house by allowing solar radiations to pass in but preventing long wave heat radiations to pass out due to glass panes, water vapours and carbon dioxide. In atmosphere, the gases which are transparent to solar radiation but retain and partially reflect long wave heat radiations are called as greenhouse gases. Important greenhouse gases are carbon dioxide, methane, chlorofluorocarbons, nitrous oxide, water vapours and ozone.
So, the correct answer is 'Warming of Earth'
