of course it is, when were we first aware of it? when the government told us about it
when was the hole in the ozone layer discovered? when they had instruments to measure it, for all anyone knows it could have been there for millennia, and be a natural phenomena due to being over the south pole

some elements are working very hard to turn it into a myth
SCIENCE HAS BEEN INVADED WITH POLITICS AND HUMAN EMOTIONS
The truth is being distorted at high levels,
And lies have been weaved in.
Some of the real dangers are being hidden because there are no solutions , Public could panic.and Authorities would loose control .
Besides Corporations have other priorities and changes will cause loss of profits ,this also affects the truths being published
Others facts are exaggerated so that the phenomena can be used to milk the people.
This is further complicated with Arrogance that will not admit that mankind could be guilty, or that Gods could be out of control ,unloving or incompetent.
Global Warming is true, there are Natural fazes but we are affecting that to a great extent ,with deforestation ,desertification and pollution., especially air pollution.
I do not think we can make a real difference anymore to change the tide.
On a Global scale,Humanity is not co operative enough .
The poor regions have other priorities such as daily survival.
There is a lot we can do about being more responsible with what we got ,
but In the first world countries many do not care or are more interested in Global Control than Global Warming.
On this forum the attitudes of Those who wish to be frugal with our natural resources and want to preserve the Nature that is left ,
are replaced by those who wish to exploit it.
So do not expect the truth this has become politically incorrect.
And listen to Trevor or Bob they do not speak with a forked tongue.
I just had a violation notice for a Best Answer,on evidences of Global warming.(things that are happening today in China,Africa and Mexico) And other have been simply deleted.
Deleted Answer:
(this answer was classified as a violation)
This week, one of NASA's top scientists concluded that the Arctic Ocean could be nearly ice-free within five years, much faster than all previous predictions.
when the north pole is gone , you may have polar bears soon in America ,looking for a home ,
Calculations do not include the accumulative ,speeding up ,factor with time. the increase in water temperature will get faster all the time as well as the melting, when the ice is all gone the deeper cold Ocean currents will stop ,and the drag has gone with it ,also changing the higher warm currents,And only the moon will keep things moving
This will affect coastal climates ,world wide ,almost instantly. All aquatic flora and fauna will be affected,many dying off and others becoming invasive,
Right now In Chiapas ,and Tabasco in Mexico .more then a million people became homeless overnight with water coming up to their roofs ,because of rains from super evaporation from the forests,this had never happened before. Millions of animals died.
In India 3000 people died because of super storms .
.A few years ago in Europe 3500 people,died during a heat wave ,many of them in France .
Right now the average death toll annually is 150.000 due to Global warming
. these figures are already out of date and are expected to double soon.
In Northern China millions of people are running for their lives because regular dust storms so far have buried 900 villages under the sand and the whole of northern China is turning into a dessert.
The Sahara is growing by 7 kilometers a year all around the edges ,like a slow burning fire shriveling up their neighbors In the Kalahari huge rivers have dried up and thousand of species are gone due to their habitats disappearing .
The biggest changes are invisible at micro biotic levels species are becoming extinct ,others are multiplying ,
This affects the insect populations that follow ,and changes in that ,affect all that follows in the food chains ,
All life is interrelated of both flora and fauna, And since we are on the top of the food chain ,
we are always the last to know.
So Global warming has its toll there are incidents all over the world ,

Nickthesurfer is correct. There is natural global warming going on following the last ice age but there has been a very significant change in the rate at which this is happening since about 1950. There is less than a 1 in 20 chance that this is happening by chance and the models of showing the impact of greenhouse gases appear logical and explain what is happening best.

I do not think it is a myth but only hope that the consequences will not be as severe as forecasted.If we can reduce global warming then perhaps in the centuries to come our efforts will be appreciated. However, I do agree that Governments are inclined to take advantage of the situation when levying taxes.

Global Warming is real; all over the world higher temperatures together with droughts, flooding, tsuamis are
playing havoc with agriculture and wildlife; the extreme heatwave in Europe in the summer of 2003 killed 4,000 people. Floods in England in summer 2007 caused billions of pounds worth of damage. Global warming isn't the only threat to the future of the planet. Over population is as great or a greater threat. Feeding the billions would be difficult enough without the threat to agriculture from global warming. The sheer quality of everyday life in our overcrowded cities
all over the world is declining rapidly; just think of the everyday
problems commuting to work where you live, the housing shortages and waiting lists for medical treatment as well as the psychological illnesses caused by living stressed lives in overcrowded conditions.

Global Warming not a myth but the idea that human released CO2 are causing it is largely a myth.
Here is a good reference on the facts of GW:

No, it's not a myth..it seems that our world has warmed and cooled periodically. (ice ages, and vines cultivated in Yorkshire etc).
But I am sceptical about how much of the current warming is man made....what exactly do the green lobby want? All of us not to travel and enjoy modern living (except for the chosen few?)...and governments are always looking for ways to tax and control us minions!

It’s possible to track changes in both temperature and CO2 going back hundreds of millions of years through the isotopes taken from drilled seabed cores (using oil rigs).
CO2 concentrations have slowly fallen over the past 100 million years as both volcanic activity and the rate of seafloor spreading has declined. The planet is now much less volcanically active and more geologically stable than it has been in the deep past. The rate of volcanic CO2 emissions declined at the same time as the rate of its absorption into the ground was increased.
Secondly, the formation of the Himalayan Mountains and Tibetan Plateau from 45 mya both increased regional rainfall and exposed great amounts of freshly shattered rock; this increased the rate of chemical weathering by which CO2 is precipitated from the atmosphere and absorbed into the land and oceans. (The carbon dioxide dissolved in rainwater helps decompose rock minerals, especially silicates, and forms bicarbonates - HCO3- - a form of inorganic carbon. These bicarbonates are soluble and are transported by rivers downstream to the coasts where they are deposited on ocean floors as sediment.)
Though astronomical (Milankovitch) cycles had caused the amount of solar energy to vary over the eras, (These cycles show clearly in the sediment cores covering the Cenozoic era.) the first of the present series of ice ages, where ice sheets advanced and retreated across the northern hemisphere, only began three million years ago. But the Earth's tilt and wobble altering the amount of solar energy only account for changes of 5 degrees of temp., the rest can only be accounted for by the accompanying falls and rises in CO2.
There have been other changes, ocean currents are very different now to those of the age of the dinosaurs because Africa, India and later S. America have joined onto continents in the N Hemisphere, this altered heat transport around the globe, as temps fell so have CO2 levels. Yes, Earth and its climate has changed over millions of years, but factors affecting CO2 concentrations have also changed as well. The two are inextricably linked. We should be on a long decline (thousands of years) into the next ice age so earth's temp and CO2 concentrations should be slowly falling, But the opposite is happening (the northern ice cap is certainly shrinking) whilst CO2 levels are rising.
Rather than think of climate change in terms of warmer or cooler also I think it better to think in terms of "wetter" or "dryer". Small rises and falls and falls in Earth's temp. alter both atmospheric circulation patterns and the amount of water vapour in the atmosphere. Some areas will become more prone to flooding and storms, others will see more occurrences of drought.
Tax incentives can also be used to encourage change, we changed in the past from wind and water energy to steam, then to combustion engines; we're technologically advanced, it can be done again. Fossil fuel industry figures I've seen indicate serious depletion of oil by the end of this century, if not before. Think of new energy sources as forward planning.

I believe that we should conserve energy, reduce our dependence on oil by developing new technologies that use cleaner sources of energy that are more readily available and that we should do our best to take care of the environment, but I think at least 90% of the .6ºC increase in temperature that we have experienced over the past 100 years in naturally caused. Here is why:

I also think the subject has become very politicised and that some people are trying to capitalize on it for their own cause, such as environmentalists, politicians and even science organizations seeking funding.

The warming may be happening but the cause is debatable. I believe all the political and economic hype is a scam. I believe that others wish to become rich and thus more powerful by scaring people into changing life styles.

It is time to stop the blame game and do something constructive to lessen the impact on all life. And at the moment one of the easiest ways is taxation. And has you will find out it is very hard to come up with imaginative ways that all side of the argument will agree to.
