the gradual increase of the temperature of the earth ‘s lower atmosphere as a result of the increase in greenhouse gases since the Industrial Revolution .The temperature of the atmosphere near the earth’s surface is warmed through a natural process called the greenhouse effect . Visible, shortwave light comes from the sun to the earth, passing unimpeded through a blanket of thermal, or greenhouse, gases composed largely of water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Infrared radiation reflects off the planet’s surface toward space but does not easily pass through the thermal blanket. Some of it is trapped and reflected downward, keeping the planet at an average temperature suitable to life, about 60°F (16°C).
