if mamoths existed during the ice age then why is it thet they can foud incased in ice?

I don't understand your question. The ice age ended about 10,000 years ago and some got covered in ice and snow when they died.  WHy would they NOT be found in ice?

an ice age increases the coverage of ice on the planet which obviously makes it colder.. but also means that radiation from the sun is reflected back into the atmosphere making it cooler again and perpetuating the ice age. precipitation also decreases, ie it rains and snows less (antartica is the driest continent in the world). wind is produced by air currents which are created by warm air rising in various patterns around the globe, so wind patterns would alter which would also affect the climate. additionally ocean currents would be altered by the increase of ice and colder waters, which would again alter the climates in maritime areas

Mammtoths were almost certainly exterminated by human hunters. The fact that they survived until historical times on a number of small islands is proof of that.\n\nWhen animal populations succcumb to climate change the fist populations to die off are the isolated island populations. Thatis because they can not migrate Northwards to colder climates climate. In the case of mammoths we see exactly the opposite occuring, with island populations surviving many thousands of years after the continental populations.\n\nThe fact that it was only on islands without humans that mammoths survived adds further weight to the idea that mammoths were exterminated by humans.

You mean emperor penquins. They migrate hundreds of miles inland on Antarctica. They have to move inland to find land solid enough to support the weight of thousands of nesting penquins. The ice shelf around the continent would not be sufficient.

that is their habitat.  how do u survive in ur habitat.  like penquins in the antarctic.   how do they survive.

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.

they kept moving south, away from the ice. They were following the food.  So improvments in hunting helped them branch away from the demanding path of the mammoths.  Then, fire and the wheel, basic I know, but they needed to get far enough south to avoid the ice, OR skin the animals for their most valuable fur.

ice ages occur due to many factors - climate change, earths  orbital changes around the sun and solar radiation changes are important.\n   no one is certain how many ice ages occur ed - but many agree that there are at least 4 major ice ages in the earths history

I have an MS in paleoclimatology, and I have to say that it is one of the most fascinating topics Ive ever delved into.  It's also amusing to see non-scientist's responses here and on other message boards!\n\nIf you wanted to ask a scientist, you would have to define what you mean when you say "ice age."  There are varying degrees of "ice ages."  For brevity sake, I will assume you mean the relatively cold periods that last approximately 100,000 years that have dominated global climate for the last 2 million years.  Contrary to popular belief, there are periods during the "ice ages" that are almost as warm as today.\n\nBased on paleoclimate evidence that suggest the ice ages have come and gone at least six times in the last 2 million years, the probability is that it will occur again.\n\nThe difficult and possibly dramatic question is: when?  Seeing as though the last "ice age" generally ended about 12,000 years ago (this is debatable, since there is no one date where everywhere across the globe it suddenly became warm), and the average interglacial is 10,000 years, we are overdue.\n\nConsider the widely accepted hypothesis that "global warming"--whether it be natural, human-induced, or a combination--can ultimately (Ill spare you the details) lead to an ice age.  Melting polar sea ice, indicator species dying off in the tropics, large disintigrations of ice shelves in the Antarctic, estimations that global sea level may rise 4 inches in the next 100 years, "wild" weather in many parts of the US...  are these all tell-tale signs that we have already begun down the road to the next glacial period?!?!?\n\nNew-ish data suggest that past climates have changed rapidly--like someone else mentioned either in this thread or another similar one--several degrees Celsius in a matter of decades or less!  The great ice sheets that once reached as far south as Long Island and Iowa wont reappear for tens of thousands of years, but it could get chilly across much of the country real quick!  And possibly as soon as 2020!

OK, where people of biblical times lived was where? Around Suadi Arabia, Iran, Iraq, Jordan, etc. That is all people knew existed.  The ice never got that far. They never saw it and had no way to find out about it.

1.) the species existed for a short span of geologic time - this is important because it makes it easier to identify certain strata. If they existed for longer periods of time then it would be harder to correlate rocks found in different places. It's like when you find it you say I KNOW this is definitely from ___ period.\n\n2.) they existed worldwide or over a very large area - in order to correlate the geologic age of rocks from continent to continent or across continents it is important that these specie exist all over the world.

That is because they have a vein/blood capillary network in their feet that is not too close to the 'skin' layer thus they do not experience frost bite. Their blood circulation is protected through lotsa insulation. Their feet are lined with scale like tissue which is used for grip and their natural body heat protects them from freezing and sticking to the ice.

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.

We are actually IN an ice age right now. This is just a warm interglacial period during an ice age, which began about 40 million years ago. During the last 40 million years, there have been ice caps on the poles, and the glaciers have advanced and retreated with periods of about 40,000 and 100,000 years. The last retreat began about 10,000 years ago. \n\nGlobal warming might keep us from cooling off. However, there are also theories that the introduction of extra greenhouse gases and soot into the air might perturb the nonlinear climate system with complicated effects, like global cooling. For example, the currents that keep Europe warm might shut off from extra rainfall over the north Atlantic (a theory of earth scientist Wally Broecker). For example, see the reference (although this is concerned with the Gulf stream, not the Deep North Atlantic Overturn, which supplies a lot more heat to Europe than the Gulf stream).

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

Living micro-organisms have been found flourishing deep within the ice of Antarctica. Since ice freezes at 32 degrees Fahrenheit, I expect that's as cold as you can get and still allow the little beggars to move about, ingest nourishment and procreate. These are simple single-celled animals. Microbia.
