How is Global Warming affecting people around the world?
We all know, the earth is surrounded by a cover of gasses as atmosphere. This atmosphere allows most of the light to pass through, which reaches the surface of earth. This light from sun is absorbed by the earth surface and converts into heat energy. This heat energy is re-emitted by the surface of the earth during night. Due excessive presence of some gasses in the atmosphere, this escape of heat from earth surface is prevented, resulting in heating of earth called ‘global warming’. The gasses which are responsible for causing global warming are called ‘greenhouse gasses’. Carbon dioxide is one of the most important greenhouse gases. This carbon dioxide mostly comes to atmosphere as air pollution from vehicles, coal-fired power plants and other industries burning fossil fuels. Human population increase and large scale deforestation are also responsible for carbon dioxide generation. Thus, Global Warming adds energy to the Earth’s biosphere.
