However, when greenhouse gases and urban development are both taken into account, regional climate modeling focused on the continental United States shows compensating impacts between the effect of urban development and greenhouse gasThe Short Answer The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat This process makes Earth much warmer than it would be without an atmosphere The greenhouse effect is one of the things that makes Earth a comfortable place to liveGreenhouse gases are gases in the atmosphere such as water vapour, carbon dioxide, methane and nitrous oxide that can absorb infrared radiation, trapping heat in the atmosphere This greenhouse effect means that emissions of greenhouse gases due to human activity cause global warming
