Asitha-K said:Ok heres my openion!
Globel worming is not good for earth! its a result of uncontrollable and unlimited polution of environment
by carban dioxide emmission!
But now all world is concerned about this matter. and the main bad guy in this story is
America because US is countrey which releases highest amount of carbon
Actually what happens in Globel warming is that it increases the tempriture of earth
and it will cause to melt glaciers in Northpole and south!
which will increase the water level of the sea and many islands will dis appear!
e.g. Maldives
That is not the only bad effect of Globel worming but it will cause
the extinction of some animals like polarbears etc...
Globel Warming also makes lots of differences in the environment that we live and effect life cycles of some species....

Not easy to express in one or two lines
The main source of global warming is happen because of Green House gases with their green house effect.
There has been 7 gases named by Kyoto Protocol as the green house gases which are harmful in world.
The effects of global warming of the rise of the world temperature & due to this melting of ice caps, low lands been submerged can be higlighted.
Another big issue emerging in the world, Urban Heat Isalnd Effect also cause of this.
Very basic things about Global Warming & more info can be browsed![]()
upulcranga said:Global warming is the increase in the average temperature of the Earth's near-surface air and oceans since the mid-twentieth century, and its projected continuation.
The average global air temperature near the Earth's surface increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the hundred years ending in 2005.[1] The Intergovernmental Panel on Climate Change (IPCC) concludes "most of the observed increase in globally averaged temperatures since the mid-twentieth century is very likely due to the observed increase in anthropogenic (man-made) greenhouse gas concentrations"[1] 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.[2][3]
These basic conclusions have been endorsed by at least thirty scientific societies and academies of science,[4] including all of the national academies of science of the major industrialized countries.[5][6][7] While individual scientists have voiced disagreement with some findings of the IPCC,[8] the overwhelming majority of scientists working on climate change agree with the IPCC's main conclusions.[9][10]
Climate model projections summarized by the IPCC indicate that average global surface temperature will likely rise a further 1.1 to 6.4 °C (2.0 to 11.5 °F) during the twenty-first century.[1] This range of values results from the use of differing scenarios of future greenhouse gas emissions as well as models with differing climate sensitivity. Although most studies focus on the period up to 2100, warming and sea level rise are expected to continue for more than a thousand years even if greenhouse gas levels are stabilized. The delay in reaching equilibrium is a result of the large heat capacity of the oceans.[1]
Increasing global temperature will cause sea level to rise, and is expected to increase the intensity of extreme weather events and to change the amount and pattern of precipitation. Other effects of global warming include changes in agricultural yields, trade routes, glacier retreat, species 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 ongoing 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.
