are we in a new ice age?

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.

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 happening... look at all the data. However, I think that "greenhouse gases" are a little overplayed as the scape goat... we ARE coming out of an ice age, after all.

Our current understanding of the long-term climate cycles shows that for the past 800,000 years, periods of approximately 100,000 years’ duration, called Ice Ages, have been interrupted by periods of approximately 10,000 years, known as Interglacials. (We are now about 10,500 years into the present Interglacial.)

No, they have ice cores from it that go back 100,000 years. Its edges were a little less icy up to about 600 years ago.

Though it may sound crazy, global warming can cause an Ice Age. You see, there's an underwater wall keeping the super-cold water of the Arctic Ocean out of the a lot warmer water of the Alantic Ocean. Global warming makes this wall dissolve, letting the cold water meet the warmer water, overall lowering the temperature of the oceans. Meanwhile, the glaciers start to melt and slide. Now that the oceans aren't as warm, the glacierscan continue to move south and cover a chunk of the Northern Hemisphere in ice. In short, an ice age.\n\nHowever, ice cores are showing that global warming isn't as bad as we thought. the ice cores show that the average global temperature 100,000 years ago would go up and down by 10 degrees in a matter of decades. In comparison, our global warming is warming at a rate of 1 degree per century. Is global warming going to cause the next Ice Age? Or are threats empty? YOu decide.

ice age.\nThey are huge ice cubes left over from the Ice Age.  Mostly in the Northern areas, such as Alaska, they carve out beautiful Fjords, and are a wonder to see.

This is complex theoram, and it happens to be taken from the exact idea of the previous ice age about 7000-10000 years ago in which only northern hemisphere froze over\nanother reason is dat the rate of pollution is higher in north then south (due to development) and effects of global warming shall be more drastic there.

No one really knows if the apparent warming we are observing is natural, a secular increase due to various natural processes. It could be due to changes in the solar constant, it could be because of complicated nonlinear effects we do not understand, it could be that we are in an interglacial period in the Milankovitch cycle, etc. \n\nHowever, it also could be anthropogenic in origin. Evidence is mounting that it might be, but it is not yet certain.

many different factors, one being us. Humans speed the natural process of global warming, just like an ice age, the earth every few million years goes through a process of warming, but greenhouse gases and other things that humans do have been speeding up the process. However, we are not the ones that cause it, since it's a natural cycle, so basically this was bound to happen. This has nothing to do with the end of the world or anything crazy like that. Some theories suggest that this will bring another ice age (a lot of water evaporates and creates a thick layer of clouds, preventing the sun from reaching the surface...the temperature gets colder and an ice age occurs. We will probably not live to see these events since they happen over a Long period of time.

The onset of the ice age.

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

Yes.  Global Warming is occuring.  It will just keep getting worse if we don't take measures to try and prevent things from getting worse.

Global warming is associated with sun spots. So if the sun spots disappear we will probably have a period of global cooling but maybe not an ice age. The last period of global cooling was around the year 1650 AD.  That period is called the "Maunder Minimum".

actually, because of Global Warming, we would be in the ice age.  The increase in temperature causes a higher density of water vapor in the air, as a result the net temperature on the surface of the earth drops, and we get lots and lots of percipitation.  The Earth is making drastic attempts to shift it's self to remedy this.  Al Gore thinks we can control it because WE caused it, and so it would stand to reason that we fix it.

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/

Barring a nuclear winter or other catastrophic event, we'll still be around, polluting, smoking, and drinking.  Humans are pretty hardy creatures, and have lived through plagues, Ice Ages, etc.  While we are using our resources at an exponential rate, I do think this will necessitate some of the newer technologies already in the works.  We'll use fossil fuels until we can't any more, but there's always other forms of energy.  Right now, its too expense to implement mass change across the globe, but soon we won't have a choice, and I can't fathom that we as people (who have been around for hundreds of thousands of years) would suddenly fail to adapt.  That's what we were meant to do- to populate this planet.  \n\nSo no, unless a catastrophe of unheard-of magnitude strikes us, we'll still be around.  People for centuries have said the end times are upon us.  I'm still waiting....
