Are we witnessing Global Warming at a very large scale that it may devour Earth in 20 Yrs?

Yeah it's getting very clear it's happening. Now we're going to have to find ways to be more efficient. It won't devour the earth, but it can potentially raise heat and suck in a few cities under water.

Possibly.\nEither by the sun dying out, thats billions of years away. Or the glaciers melting, thats possible in a million or two, given our pollution. \nA meteor hit can do it, like dinosaur wipe-out. Probability is one in a billion, but hey we have been around for that long or more.

ok now here is some truth for you. Global warming is a THEORY nothing more, it has not been proven. an ALL the scientists do not agree. more than half do not agree and because of that they do not get media coverage. That is why all you hear is global warming on the news because it gets ratings. Many, many scientists agree this is a phase, the earth has wamring periods and cooling periods, we just now are getting out of a cooling period. every here of the "year without a summer" in the 1770's. that was the height of the cooling period. if you look back further in the 1300's it was hotter then, than it is now according to historical evidence. Volcanoes produce almost 10 times the green house gasses then humans produce per year. Nature is not this fragiel little thing like all the libs want you to believe, its very tough and adaptive it recycles many of the wastes we produce but also many of the wastes itself produces which in comparison to ours is infintismal. I agree we should not be reckless and find better, cleaner and more efficient ways to do things. If you want the truth, yes global warming is true, the "globe" is "warming" but not because of the Dodge Diesel you drive, but because its a cycle and in a few centuries it will begin to cool again. Most people here never heard of what these very same scientists were saying in the 70's. the same people screaming about global warming were do the same thing about "global cooling" in the 1970's and some suggested we put coal soot on the ice caps to gather heat from the sun to melt them. Look it up, its true. So before you goes starting going nuta about this global warming farse, do your homework instead of believing everything you hear on the ratings driven news everynight.

The Earth is already living on borrowed time. Consider this:\n\nWe're overdue for an E.L.E.* caused by an earth-crossing asteroid.  Geologic evidence point to massive bombardments every 12 million years or so, the last big hit was about 11-12 million years.  It is not only highly probable, but an astromonical surety that someday we will again face this threat. Few people realize how many close calls we have had in that last couple of decades.\n\nThen there's the threat of emerging pandemic viruses that might wipe out a great majority of mankind.  Or a disease which bould wipe out our crops or food and animals.  There is the threat of ecological disaster, which the geological records shows happens in cycles of hundreds of thousands of years. We may be plunged into another Ice Age or face massive global warming.\n\nAnd lets not forget the destruction we bring on ourselves from nuclear weapons.  Guess how many times since 1950 that we've been a hair's breath away from utter destruction?  False alarms and warnings, and tensions number around 20+, and these are just the public ones we know about.  Even in post-Cold War era there was that 1995 incident in Russia, and i could go on.\n\nMy point is, the Universe is a hostile place and we have only scratched the surface of how improbable our continued existence is, according to the odds.  We have beaten the odds, but probability has a way of catching uyp to you.

It is too early to tell but with Global Warming the chances are getting better and better!\nBut it would be pretty weak.

Climate change is a natural cycle for the Earth and will happen regardless of human interferance. In fact if you look at the cycles of Glaciation and Warming over the past few hundred millenia, we are probably due for a massive cooling phase, maybe even dramatic glaciation, sometime in the next few hundred years. A number of things affect this, most notably the tilt of the Earth in relation to the sun. This is effected by the cycle of the planets and their orbits, and cannot be changed or prevented. We are due, and when it happens it is likely that large portions of the northern hemisphere will become covered in glacial ice, as happened about 20,000 years ago, and lasted until about 8,000 years ago. The mini-glaciations happen in about 10,000 year cycles, so our current warm period (an inter-glaciation, not a warm period) is due to end soon. \nOne of my archaeology professors said to me once that it may well be deemed that the breif delay in this caused by carbon emissions may be deemed the greatest attempted effort of human engineering well in the future.

Barring the very unlikely event of a meteor hitting Earth, no, the world isn't going to end any time soon.\nIf you mean, could our lives change drastically because of global warming soon, well, perhaps.  But Earth itself will continue.

We are currently nearing the warmest point in our meteorlogical history during the Holocine Epoch, the temperature will decrease quickly (geologically speaking) and we will enter an "ice age" in the next 40 million years.  The eventual glacial erosion, if substantial, will begin the next epoch.

Start with Al Gore's Inconvieniant Truth to get the big picture. Then if you can consider other people elsewhere besides where you live you would know they are being effected right now. The world is warming up and ice is melting everywhere. We should all be very concerned......

Well, I don't think I can convince you; you're apparently believing false information...but rest comfortable in knowing that the atmosphere is not deteriorating and nothing drastic is going to happen…during your lifetime.\n\nThat being said, eventually, the Earth (and its atmosphere) will wind down to a point where it won't sustain human life. That's the natural process, but we won't see it for several billions of years.\n\nHumans couldn't destroy the atmosphere or planet if we tried...even with nuclear weapons.\n\nOther people may answer with differing opinions, but their "evidence" is based on false science and anecdotal evidence and is designed to be alarmist. There's no rest for the weary!

"Are we destroying the earth with technology or is the earth doing business as usual"\nI suggest you track the changes scientists have found in the entire history of the earth, warming, freezing, wet and even effects of smoke from Krakatoa. Then compare what is happening now with pollution and the depletion of the ozone layer and ask the readers to make their own conclusion.

Global warming is the term used to describe how the average temperature of the planet is going up. No one denies that the temperature is, in fact, going up. Therefore, no one denies that global warming is a fact.\n\nHowever, according to studies of Antarctic ice, the average temperature of the planet has been rising for 6,000 years, which is well before the Industrial Revolution of 150 years ago. This proves that global warming is not caused by man. In that time, however, the rate of temperature rise has increased, which means that the actions of humanity probably has worsened the situation.\n\nThe critical facts about global warming are these:\n\nWhat are the effects of global warming going to be, and how can we prepare for them? Currently, no model of global atmospheric projection has shown itself to accurately predict to any degree the general weather patterns of the Earth (such as the number and ferocity of hurricanes). Until we come up with an accurate way of predicting the effects of global warming, preparing for them will be difficult and based upon conjectures, which are a difficult sell to taxpayers.\n\nWhat can be done to limit the effect of humanity on global warming in the future WITHOUT putting a major damper on economic growth and development, especially in developing nations? For example, all nations could agree to stop driving vehicles that use internal combustion engines, but to do so at once would devastate the economies of many nations. However, other options, such as diverting tax funds to subsidize the development of alternative-energy propulsion for vehicles, would accelerate the advent of such earth-friendly technology.\n\nAll in all, because of the massive stakes involved when discussing global warming (and the subsequent misinformation flying around about it), many people are confused as to the facts about it. I was hoping to be as informative and unbiased as possible.\n\nPlease let me know what you think!

Yes, global warming has started and finished and started and finished.\n\nThe earth has been much warmer before and much colder.  It will be both much warmer and much colder again many times.

CO2 is 30% higher than it has been for 650,000 years. Methane is 130% greater. These are two of the main pollutants humans put into the atmosphere in excess, and they are two of the primary greenhouse gases.\n\nLook at the 'hockeystick', which shows a dramatic warming since 1950 after a fairly stable climate for 1000 years. In fact, the 10 hottest years in recorded history have all happened since 1990, with 2005 being the hottest.\n(see links below)\n\nHow's that for proof of man's fault in this? There is ample proof, any real scientist will tell you that.\n\nThere has NEVER been an article doubting man's influence on global warming published in a peer-reviewed journal. A recent study of almost 1000 proved that.\n\nYes, the earth naturally heats and cools, but the rate and amount we are warming now is unprecedented in the recent geologic past. We are doing this, and we must stop it. This is not some political statement or rhetoric. This is science trying to educate a crass, ignorant public of the damage they are doing. The magnitude of temperature increase ALREADY is about 10x that of the 'little ice age' of the middle ages, and rate and amount are only going up. \n\nJust to be clear, glacial and interglacial cycles are mainly controlled by astronomical fluctuations, but we have a detailed record of the last 7 cycles, and what the climate and CO2 is doing now is way different and extreme. The rate of increase is much higher than in the past AND the value itself is much higher.\n\nHI CO2: \nhttp://news.bbc.co.uk/1/hi/sci/tech/4467420.stm\nHOCKEY STICK: \nhttp://news.bbc.co.uk/1/hi/sci/tech/5109188.stm\nGeneral climate stuff: \nhttp://news.bbc.co.uk/1/hi/sci/tech/3897061.stm

The climate has been changing since the earth's begining, so no. \n\nHuman activities are contributing to a faster rate of change, but there is nothing practical we can do about it. \n\n Adapt to the new world.  We will never be able to reduce emissions fast enough- India and China are just getting started with industrialization on a large scale (using coal power, primarily) and unless the whole world goes to nuclear power there is no other viable option for stopping climate change before it is too late.   (and nuclear power is still a bad word in environmental circles)\n\nSad but true

What are you mentally retarded ? Global warming is very much real.

20 years? hmmm... by that time we will probably be so overpopulated that scientists will have to think of building communities on other planets to accommodate the ever growing population of earth...
