do you believe we are in a new ice age now, or will we see it start within our lifetime? i live in alabama. what can i expect the effect of the next ice age to be on my home state?

The circulation the the North Atlantic that brings heat to different parts of the world is believed to be slowinging down due to global warming thus me may be in the beginning stages of an ice age but it will take a few decades before we know for sure.

I believe global warming is more natural than the enviro-Nazis are giving credit for. I believe whole-heartedly that the Earth has gone through this cycle MANY times. While our polution is having an effect, and we should not have unlimited polluting, it does not have the effect of a volcanic eruption and other natural events.\n\nI refuse to be one of those uber-whackos that thinks that we should try anything to force the human race to go back to loin cloths and spears, riding on horseback. But I also do not believe we should dump and spew everything back into the environment without thinking of the effects. There has to be a happy medium.\n\nI do not really know, as even the scientists do not really know, if we are still moving away from the last ice cycle, or we are past the opposite point and we are moving back towards another ice age. In any case, we need to try and understand it more, and the effects of everything more.\nGood question though.

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\n\nnow to give you sorces and go into more depth on what i just wrote\n\nwell lets see first. ice ages.\n\nAn ice age is a period of long-term downturn in the temperature of Earth's climate, resulting in an expansion of the continental ice sheets, polar ice sheets and mountain glaciers ("glaciation"). Glaciologically, ice age is often used to mean a period of ice sheets in the northern and southern hemispheres; by this definition we are still in an ice age (because the Greenland and Antarctic ice sheets still exist). More colloquially, when speaking of the last few million years, ice age is used to refer to colder periods with extensive ice sheets over the North American and Eurasian continents: in this sense, the last ice age ended about 10,000 years ago. This article will use the term ice age in the former, glaciological, sense; and use the term 'glacial periods' for colder periods during ice ages and 'interglacial' for the warmer periods.\nMany glacial periods have occurred during the last few million years, initially at 40,000-year frequency but more recently at 100,000-year frequencies. These are the best studied. There have been four major ice ages in the further past.\nso we are in an ice age interesting that means it is warming up. well that is my argument but there is more so i will continue.\n\noh my sorce for the above exerpt is http://en.wikipedia.org/wiki/ice_age... so go there and read more if u want\n\nhere is more reading on ice ages\nhttp://library.thinkquest.org/j001457/fa...\nhttp://www.museum.state.il.us/exhibits/i...\nhttp://www.geologyshop.co.uk/iceages.htm...\ni am not making this up ice ages exist this is the basis to my argument.\n\nthen i said there is ice and water and the same amount of water is here that was millions of years ago again not made up\n\nThere is about the same amount of water on Earth now as there was millions of years ago.\nsource: http://www.dnr.state.wi.us/org/

There is such a great debate going on about the issue of global warming.\n\nGroup A..says that emissions from cars and industry are effectively changing weather climates and as a result mean temperatures are starting to rise.  For example most of the hottest days on record have occured within the last 50 years.\n\nGroup B...says that global warming is figment of the imagination and that the current rise in mean temperatures is nothing more than part of a larger weather pattern that faciliated the ice age and so on.\n\nEither way, it is up to you and your spending habits about who you choose to believe.

Claymore,\n\nI love you! Will you marry me? My global warming argument has always been this: The world was more than once covered in ice and is not now covered in ice. Therefore, global warming must have occurred. The last ice age was more than 80,000 years ago, well before America and George Bush were here. Isn't it remotely possible that global warming can occur naturally?

You have a reasonable argument that current shrinkage may not be that different from the past: \nThis from USGS web site:\nFluctuations are not new to Lake Chad. About 10,000 years ago Lake Chad almost filled its present drainage basin, and spilled southwest out the Benue River to the Atlantic. In the last 1,000 years, according to fossil evidence, the lake probably dried out a half-dozen times. (Most of its fish are river-adapted species.) Geologic data, climate data, historical accounts and reconstructions all indicate a higher long-term variability than the relatively short period we have actually measured. The chart shown here shows levels since the 1870s, from actual measurements and from estimates based on Nile River discharge.6\n\nFollowing highs in the 1870s and 1890s, the lake dropped enough by 1908 to separate into north and south pools, with the "Great Barrier" between. In the 1950s the lake rose enough to flood out irrigation systems, peaking this century in 1962. The lake then tapered off until the early 1970s, when it plummeted. The recent low levels are a concern, and have been monitored through satellite and other means by the Lake Chad Basin Commission and others.==url below\n\nWhether or not it has dried out in the past, people have come to rely on it. Worrisome, I'm sure, to government agencies concerned with food supplies, irrigation, biodiversity, water availability etc.  And I would suppose that any future increase in drought or temperature  warming would guarantee a smaller lake, or its disappearance again.

When Plato's ancestor Solon went to Sais in Egypt (600 BC), the priests told him about Atlantis. They also said that inscriptions on their temple walls told how many times civilisations had risen to great heights and then fallen because of natural catastrophes such as floods, fire, earthquakes, etc. I think that maybe we are being a little presumptuous to think that it can't happen to us. I have spent the last 15/20 years researching a related subject and in my opinion the last great catastrophe was 9600 BC, with the sudden and abrupt end of the mini-ice-age called the Younger Dryas period. I believe that this is the basis of the Biblical flood. Getting back to today - the Christian versus Muslim thing - yep, of course it coming, you can smell it! I should imagine that most of the faceless men in grey suits already know this and are moving their pieces on the world chess board accordingly. Humans are amazing - we've been on the moon and sent machines out to beyond the solar system, I can pick up my phone and talk immediately to a person on the other side of the world, I can sit in my armchair and with the smallest of thumb movements be entertained by 100 different TV channels - but with the flick of an eyelid this civilisation can be destroyed because people believe that their unseen and unproven overlord of the cosmos is better than the other man's invisible and all-seeing ever-present boss. It almost makes you want to scream! We're such clever animals - but I don't think that we're too intelligent - and when it's all over we'll begin again.

Is global warming to our benefit?  \n\nI say this because global levels of environmental Carbon(13), an isotope of Carbon(12), is used by us geologists as a way of identifying paleo-glacial maximums.  A high Carbon(13) level coincides with periods of high glaciation (i.e. ice-age).  \n\nRight now the levels of environmental Carbon(13) are at a level that should indicate the beginnings of an Ice age.  Clearly things are getting warmer, not cooler.  So the question is: is human Carbon Dioxide/Carbon Monoxide input actually holding back the impending Ice age?\n\nAlso, why do so many people think that the atmosphere should be static.  The global temperature is always increasing or decreasing.  It's never static.

Without a doubt the Great Drought will return. Nobody can say when, but exactly the same weather systems exist today as existed then, so one day the same pattern must recur. It might be next year, it might not be for another 1000 years, but it will recur.

despite the idea of the earth changing drastically - this is still over millions of years .... in your life time, there will be no ice path from Russia to wherever.\n\nWhatever is going to happen with Mother Earth... well there is the general understanding that it will happen over time, a long time - though the oceans have increased two degrees over the past decade - thus the storms in the US of A have become stronger... but to the extent of total chaos due to Mother Nature - not likely going to happen in our life times .... though very cold winters and droughts, and large amountys of percipitaiton, and warm winters, hot summers, cold summers ... these are a part of the changes that are just normal.\n\nThere are some that say because of the rise in water temperature, that the ocean current may change drastically - making Europ very cold, and America very hot... some say there is already a 30% reduction in water that is in the current - bringing cold water to the warmer zones and vise versa - this caused by fossil fuel emmissions - in which case, yes this could be a very fast change, but this is man, not mother nature's doing.  Storms in America would then be ten times as strong, and climate in Europ - prevent a lot of crops from growing... yes this would be chaos, but not the chaos that you think of concerning an ice age.

1.  Yes, temperatures actually have been rising - in certain places.  2.  No, it isn't too early to make predictions, as long as they are based on sound, unbiased scientific findings.  3. I believe that the warming is being driven by both people and natural causes.  We can do something about the former, but not the latter.  To what degree (no pun intended) each one is a factor is still up in the air, I think.  4.  Yes, it certainly could benefit some regions of the earth, but it would damage many populated regions tremendously.  That's why we need to try to slow down the human contribution a.s.a.p.

yeah I heard all the crap about the new ice age what a crock same thing about human activity causing global warming bunch of nonsense read the astronomy reports the sun is burning a little hotter it does this ever so often like during the middle ages and think about it haven't we been coming out of an ice age for the past ten thousand or so years does this not mean it has been getting warmer

It's hard to predict a date that we will all die, but problems are already happening.\n\nCO2 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 artic ice shelf IS melting .Not a myth .Polar bears ARE drowning .Artic communities have experienced increased flooding and evacs.Worst droughts out west since the thirties.There is abundant evidence of glaciers retreating.The science is out there and I will believe scientific evidence and experience  over people who want to bury their heads in the sand and stupidly do nothing any day of the week.Don't let yourself get conned by people who are in denial and have no proof of their own to contradict scientific evidence and eyewitness accounts .Global warming is no joke and we must do something to prevent it from getting worse now before it's too late.

Well no i think the time period set for the drastic climate change int he movie is too short. Although when looking at history we did have an Ice Age in just 100 years (shortest ever) so in a way it could be possible.

I consider you lucky too I live not to much more north than you... i live in georgia... about 2 hours away fron jacksonville.. and is 38 right now. and I just found out we're under a snow advisery.

During the next 5 years, I hope to see a Democratic sweep in all state and Federal governments (at least we will get a different set of lies), I am afraid we will see rampant inflation, horrid interest rates, serious weather pattern changes including more and more serious hurricanes on the East Coast. I expect that during the next 10 years, our ocean levels to begin rising causing more and more flooding in the gulf and East Coast. We well could face a serious uprising of the population due to the Iraq ordeal...very much like we had with Viet Nam. I do not foresee good times ahead. I also think our problems with Mexico have just started. I hope I am wrong.
