Global warming.....

What do you understand about it???

Is it when the earth become warm and hot we can directly assume it as global warming??

Ha...actually 'Global warming ' is the increase in the average temperature of the Earth's near-surface air and oceans since the mid-twentieth century.The average global air temperature near the Earth's surface increased during the hundred years ending in 2005. The Intergovermental Panel on Climate Change(IPCC) concludes that "most of the observed increase in globally averaged temperatures since the mid-twentieth century is very likely due to the observed increase in greenhouse gas concentrations via an enhanced greenhouse effect. Natural phenomena such as solar variation combined with volcanoes probably had a small warming effect from pre-industrial times to 1950 and a small cooling effect from 1950 onward.

While the effect of increasing global temperature is expected to cause sea level to rise, an increase in the intensity of extreme weather events, and significant changes to the amount and pattern of precipitations. Others are expected effects of global warming include changes in agricultural yields, modifications of trade routes, animals extinctions and increases in the ranges of disease vectors.

Remaining scientific uncertainties include the amount of warming expected in the future, and how warming and related changes will vary from region to region around the globe. Most national governments have signed and ratified the Kyoto Protocol aimed at reducing greenhouse gas emissions, but there is on going political and public debate worldwide regarding what, if any, action should be taken to reduce or reverse future warming or to adapt to its expected consequences.

So, from that article I would like all of you try to feel and imagine how is our life in the future due to the increasing of Global Warming in the world now......please my frenz.....
