Global Warming

Global Warming

Scientists believe the rapid warming in the last several decades is due mostly to human-induced changes to the atmosphere, on top of some natural variations. Climate change induced by human activity may occur due to changes in the composition of the Earth’s atmosphere from waste gases due to industry, farm animals and land clearing, or changes in the land surface reflectivity caused by land clearing, cropping and irrigation. These gases include several, such as carbon dioxide, methane and oxides of nitrogen, that can absorb heat radiation (long-wave or infra-red radiation) from the Sun or the Earth. When warmed by the Sun or the Earth they give off heat radiation both upwards into space and downwards to the Earth.
