what is really happening, some people say that another ice age will come. others say that global warming will?

Actually both are true.  However, global warming and an impending ice age will not cancel each other out, as far as, average temperatures are concerned.\n\nGlobal warming, whether caused by mankind or nature, will usher in another global ice age.\n\nAlthough this sounds contradictory, there is an explanation that I will attempt to explain:\n\nAtlantic ocean currents circulate from the warmer southern Atlantic ocean northward to the colder waters.\n\nAs the warm waters flow north, they cool down, and thus, begin to sink deeper into the colder northern Atlantic waters.\n\nThis colder water then continues to flow southward, and thus, begins to warm up again the closer it gets to the equator, effectively creating a self-sustaining flow.\n\nAs this colder water warms up, it begins to rise toward the surface where it continues to get warmer.\n\nThen, these warmer waters are caught into the northern flow\nwhere they will eventually begin to cool down again, sink, and continue the flow back southward.\n\nIt is this flowing current from warm to cold to warm again that regulates our weather systems.\n\nNow then, as the Earth warms up because of global warming (manmade or otherwise,) the Atlantic current is in danger of being disrupted and stopped.\n\nWhy?  Because as the northern Atlantic waters warm up, there will be a point at which the northern waters are too warm for the water to cool and thus sink.\n\nOnce the northern waters stop sinking, the whole process will come to a screeching halt.  Therefore, no more Atlantic current.\n\nNo more Atlantic current will then halt the process of "warmer" waters from flowing northward.\n\nOnce this massive amount of warm, energy filled waters stops flowing north, the Northern Hemisphere will then start cooling down enough to mark the beginning of a new ice age. \n\nHope this helps...\n\n-AwareOne\nAwareones@yahoo.com

global warming is definitely the answer.  once the polar ice caps melt, the temps will skyrocket.  i expect that this summer will be cool and wet also.  this will continue, more than likely, until the ice caps are gone, then no more moisture, just hot dry temps with no end in sight.

Probably not. I think the end will come from environmental destruction causing melting of the ice caps, then, when the balance of the planet is thrown off enough, the earth will change its axis of rotation ( as it has done several times already according to the geologic survey ). This will be devestating to all life on the planet and the earth will be reborn.

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.

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.

there is no unbias news sorce they are all liberal and it has been proven. but my opinion is it dosent exist. because think about it we are coming out of an ice age. it makes sense dosent it? fact: there have been ice ages. fact: there is a lot of ice in ice ages. so if you know about water then you know the same amount of it is here that was here when the earth began so literally it is dinasor piss. well during an ice age lots of stuff is covered in water/ice ( i know i live in minnesota and it is known that it was fully covered with ice.). so where is all the water? in ice bergs, glachiers, ect. so it would make sense that to leave an ice age most things would melt right? so they are still melting they will finish melting and cover parts of the world, then it will slowly freze causing an ice age. why would humans make that big of a difference? we are insignificant to the world.(everyone in the world could fit in texas and it would only be as densly populated as ny city). so our vehicles and combustable engines couldent have that big of an effect. but you say "what about the ozone thinning?" well i am not saying it hasent but it was because of the cfc's(cloral floral carbons) which broke up the ozone by atatching to ozone molocules. but the cfc's are no longer around. the ozone is healing itself as it is meant too. ther was no real hole only a thining which is also bad. but now it is closing up and returning to normal. if you think that the co2 we produced cant be good well think about it it isnt that mutch and while the earth was cooling after beieng created it released tons of co2. so what people will notice in the next 1-9000 years is it will warm up but in that time it will also cool down and eventually there will be an ice age. just because the great human race is here dosent mean that the earth will stop having ice ages as it has done by its self for billoins of years. think about it.

honestly global warming is a big f'n lie. If anyone knew anything about meterological weather history, they would know this "overall world warm up" happens all the time, along with the "overall world cool down" if you knew anything about science in that area, you probably wouldnt be a crazy liberal. PS, driving a enviornlementaly friendly car isnt going to do squat.

because they are to dumb to look back at history because it dosent exist. because think about it we are coming out of an ice age. it makes sense dosent it? fact: there have been ice ages. fact: there is a lot of ice in ice ages. so if you know about water then you know the same amount of it is here that was here when the earth began so literally it is dinasor piss. well during an ice age lots of stuff is covered in water/ice ( i know i live in minnesota and it is known that it was fully covered with ice.). so where is all the water? in ice bergs, glachiers, ect. so it would make sense that to leave an ice age most things would melt right? so they are still melting they will finish melting and cover parts of the world, then it will slowly freze causing an ice age. why would humans make that big of a difference? we are insignificant to the world.(everyone in the world could fit in texas and it would only be as densly populated as ny city). so our vehicles and combustable engines couldent have that big of an effect. but you say "what about the ozone thinning?" well i am not saying it hasent but it was because of the cfc's(cloral floral carbons) which broke up the ozone by atatching to ozone molocules. but the cfc's are no longer around. the ozone is healing itself as it is meant too. ther was no real hole only a thining which is also bad. but now it is closing up and returning to normal. if you think that the co2 we produced cant be good well think about it it isnt that mutch and while the earth was cooling after beieng created it released tons of co2. so what people will notice in the next 1-9000 years is it will warm up but in that time it will also cool down and eventually there will be an ice age. just because the great human race is here dosent mean that the earth will stop having ice ages as it has done by its self for billoins of years. think about it.

one theory of alternating weather condition like the global warming and ice age is the Milankovitch theory. He explained there (Milankovitch) that alternaing global warming and ice age are natural event due to eccenticity, obliquity and precession of the earth.\nHuman just hasten the global warming due to excess CO2 from burning materials extracted and made by man.

Isn't global warming enough?! Because of this ice bergs are melting which mean animals will die. Air is becoming thinner which means we can die.  Global warming IS something to worry about!\n\nwww.stopglobalwarming.org

definitely. it's practically the one part of global warming scientists agree on.\nover the next century, we will see the oceans warming and thus expanding (sadly flooding places like Venice), also the polar ice caps melting (once again, not good. they keep the earth cool...see a vicious cycle?), not to mention serious climate change and animals migrating to the north to keep cool. it's already happening...yikes!

There are a few aspects to be addressed when discussing global warming...\n\nGlobal 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.  What has been the degree to which we have?\n\nThe critical questions to be answered 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\nAnd yes, I am Republican.\n\nPlease let me know what you think!

no in my opinion is it doesn't exist. because think about it we are coming out of an ice age. it makes sense doesn't it? fact: there have been ice ages. fact: there is a lot of ice in ice ages. so if you know about water then you know the same amount of it is here that was here when the earth began so literally it is dinosaurs piss. well during an ice age lots of stuff is covered in water/ice ( i know i live in Minnesota and it is known that it was fully covered with ice.). so where is all the water? in ice bergs, glaciers, etc. so it would make sense that to leave an ice age most things would melt right? so they are still melting they will finish melting and cover parts of the world, then it will slowly freeze causing an ice age. why would humans make that big of a difference? we are insignificant to the world.(everyone in the world could fit in Texas and it would only be as densely populated as NY city). so our vehicles and combustible engines couldn't have that big of an effect. but you say "what about the ozone thinning?" well i am not saying it hasn't but it was because of the CFC's(chloral floral carbons) which broke up the ozone by attaching to ozone molecules. but the CFC's are no longer around. the ozone is healing itself as it is meant too. their was no real hole only a thinning which is also bad. but now it is closing up and returning to normal. if you think that the co2 we produced cant be good well think about it it isn't that much and while the earth was cooling after being created it released tons of co2. so what people will notice in the next 1-9000 years is it will warm up but in that time it will also cool down and eventually there will be an ice age. just because the great human race is here doesn't mean that the earth will stop having ice ages as it has done by its self for billions of years. think about it. am i a genius or what i mean i just looked at what has happened in history wow who would have thought history would repeat its self

Well, the weather changes very quickly, however global warming has been happening for a while. It is in the past while predicting the weather is in the future. There is data that shows a warming trend on Earth. So, you can trust it, at least as fact that is IS happening. Most people agree on that. However nobody is sure whether or not this heating is natural or caused by humans.

Yes definetly, infact it has already started. there are many theories that link to global warming including that the glaciers would melt because of the rise in temperature and that will cause sea levels to rise. It may also cause a problem for geese migrations. Summers will get even more hotter, a decrese in snow may also be possble. But thats just my opinion

Many scientists believe that we are actually heading toward a global ice-age as opposed to a global warming.  \n\nAlthough a work of FICTION Michael Crichton's "State of Fear" provides evidence to support this.\n\nI suggest reading it (it's FIRST AND FOREMOST a good FICTION book, but is supported by genuine theories and statistics that ARE IN FACT from "Science" and "Nature" magazines, the worlds fore-most scientific mags)\n\nTo be honest I don't think we're experiencing anything unnatural about our environment right now.
