Global Warming


GLOBAL WARMING AWARENESS

There has been a considerable increase in the average temperature of earth in the past century. This rise in temperature is attributed to the effects of global warming brought about by the accumulation of greenhouse gases in the atmosphere. This phenomenon is called Global Warming. The effects of global warming are numerous. The main culprits in the issue are excessive discharge of green house gases in the atmosphere.

Global Warming Facts - How does it affect you?

The green house gases like carbon dioxide, methane, and nitrous oxide are playing hazards in the present times. These green house gases trap heat in earth’s atmosphere and thus result in increasing the temperature of earth. The excessive emission of these gases is one of the major Causes of Global Warming. The major source of carbon dioxide is the power plants. These power plants emit large amounts of carbon dioxide produced from burning of fossil fuels for the purpose of electricity generation.

The global warming has led to increase in mean earth surface temperature and thus melting of polar ice. There are frequent melt down of glaciers that result in floods and other natural calamities. The melting of ice at the poles had led the mean sea level. And further increase in temperature may further melt the ice and lead to further increase in mean sea level, which will engulf low lying countries.
