Question

Information on global warming?

Answer 1

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.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" via the 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.

These basic conclusions have been endorsed by at least thirty scientific societies and academies of science, including all of the national academies of science of the major industrialized countries. While individual scientists have voiced disagreement with some findings of the IPCC, the overwhelming majority of scientists working on climate change agree with the IPCC's main conclusions.

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.The 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.

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.

Answer 2

Many observations indicate that global warming has taken place during the 20th century. Global warming has resulted in a increase of the average surface temperature, a decrease in snow cover and ice extent and a rise of the sea level. Moreover, global warming affects precipitation, cloud cover and extreme temperature                                                                                                                  The warming of global climate is now unequivocal. There are many observations of increasing air and ocean temperatures, widespread melting of snow and ice, and rising sea levels.

Answer 3

yeah, its something about green house effect on the earth due to excessive  burning of hydrocarbon which produces carbondioxide(this has the property to absorb heat from the sun)thus increasing the surface temperature on earth.this rise in temperature results into melting of icecaps in the polar regions which is a threat the major cities on the caostal regions.

Answer 4

It's a lie...just like "Global Cooling" was in the 1970's. This too was brought to us by the same idiots.

Answer 5

Yeah, I know that it is increasing every day and its  caused mainly due to cfc's and automobile pollution.

Answer 6

It is a natural cycle which earth has experienced many times in the past, as global cooling has also occurred.

I don't know what sort of information you are asking for however.

Basic science could help, if you wish to know the truth.

I am not in the habit of giving links to websites, just to support my understanding of science, but I think that these are worth checking out.

If for no other reason than to see the farce about what this issue really is all about.

This will give some very 'Inconvenient Truths'.

On that site, you will also have the ability to listen to a radio broadcast which shows how the scientific community has been censored.

I hope this helps a little.

I hope that you are not one of those that are willing to be lead astray by following someone who is following someone who is lost.

There are far too many important and realistic things that man can change to improve our lives.

Answer 7

Global warming is the increase in the amount of green house gases such as methane, carbon dioxide etc in the earth surface this acts as a barrier which captures the heat and light of the sun escaping through the earth's surface. global warming can cause climate change leading to melting of ice caps and increase in the level of water in sea and oceans.
