What is Global Warming ?

A slow but sure escalation in the overall temperature of the Earth's atmosphere generally attributed to the g r e e n h o u s e e ff e c t caused by increased levels of carbon dioxide, CFCs, and other pollutants is called G l o b a l Wa r m i n g .Back to

CausesOne of the most

prominent causes of the Global Warming is the G r e e n h o u s e E ff e c t .

Greenhouse Effect

Greenhouse EffectThe partial trapping of solar radiation by a planetary atmosphere, similar to the trapping of heat in a greenhouse.B

ack to TOC

When greenhouse gases like carbon dioxide, methane, chlorofluorocarbon(CFC’s) etc. trap the outgoing solar radiations of the sun reflected by the surface of the earth and do not allow the heat to escape then this is known as greenhouse effect which causes GLOBAL WARMING.

EffectsGlobal Warming has numerous harsh effects which are represented by these pictures:

What can be done ?"As a society, we can

blunt the worsening of global warming by immediately cutting back on our wasteful energy usage. If we do nothing, the effects will be much worse."
