What is the greenhouse gas effect and what are the atmospheric gases responsible for this effect? Earth rising global temperature is primarily the result of greenhouse gases which have been ‘mirroring’ back more heat than they have in the past, due to their larger concentration. The most dominant greenhouse gases which have contributed to this predicament are water vapour and CO2. The emission of carbon dioxide into the environment has resulted from burning fossil fuels which has led to this greater concentration in greenhouse gases. The main greenhouse gases are: †¢ Water Vapour †¢ Carbon Dioxide †¢ Methane †¢ Ozone ...and... †¢ Nitrous Oxide The American Government officially released a report stating that the biggest source of greenhouse pollution (restricted to the United States) is electricity production, which, in 2013 generated over 31% of of greenhouse
