Answer 1

There is no doubt that the Earth will someday experience another Ice Age. There have been many, many periods of time during Earth's past which were considerably lower than they are now.

During the Precambrian period, there was an ice age so great that there is evidence of glaciers covering regions that were at the Equator at the time.

There is no reason to believe that it will not happen again. Since Antarctica moved into its present position south of the Antarctic Circle several million years ago, it has acted as a tremendous heat sink and resulted in much more numerous and frequent ice ages.

We will get one again. However, it's virtually impossible to predict exactly when.

It's possible that the increasing temperatures we have experienced over the last century will actually result in another ice age. It sounds counter-intuitive, but it's possible. If ocean temperatures increase, it can disrupt the currents and streams of water movement in the oceans. For example, the Gulf Stream that carries warm water up from the Gulf of Mexico to the Grand Banks of Newfoundland and across the Atlantic to Great Britain.

Were the Gulf Stream to be disrupted, it could result in rapid glacier formation in the Arctic Ocean, and plummeting temperatures in the north Atlantic (not exactly the warmest place to begin with). Even though temperatures are increasing in other areas, the north could easily start packing on ice, and lowering temperatures in that area. The mix of warm air from the south and cold air from the north could increase precipitation, including snow, and increase the build up of glaciers in the north, rapidly covering Canada in ice (again), and moving south.

Climate is such a chaotic, interdependent system that it's hard to predict exactly what will happen long range. Once the balance is upset, there's no way of knowing which way it will topple over - like a spinning top that's bumped.

So global warming could very well result in a new ice age. Or we might just get so hot that all of North America turns into an uninhabitable desert. Or it might turn into lush, tropical forest. Hard to say at this point.

Some of the calculations of the onset of past glaciations during the Pleistocene have shown that certain periods may have gone from warm inter-glacial to full on, ice coated maximum glaciation in as little as twenty years. So we could very well live to see massive ice sheets destroying Toronto.

Answer 2

If the ice melts too fast we certainly experience anothe rice age.
The melting ice would not only cool down the jet sea/ocean streams causing a mini ice age in europe and possible america it could also flood and distroy most small islands.
There are several things that could signal a total new ice age like ametor or comt hit. The world goes though a fast warming period and thna heads into an ice age.
Enough nuclear explosions, volcano erutions could force an ice age as the ash and smoke blanketed the earth cooling it down. this could signal a major total ice age.

Answer 3

Absolutely agree.
I don't know if it can be 'predicted', but the earth goes through cycles. Man has been here for maybe 10,000 years, that's less than .1% of the earth's age.
A meteor strike, several volcanic explosions, or a nuclear war are just one of many ways to start an ice age. All you have to do is get enough dust in the atmosphere to obscure the sun and voila! we have an ice age.
You'll notice on the wiki image that an increase in dust in the atmosphere (the red line) corresponds to a significant drop in temperature (the blue line).
BTW, the earth has been through 4 "ice ages" that we know of.

Answer 4

Yeh I reckon so:
The earth is supposed to be getting colder pretty soon, but we've really stuffed that one up with all the greenhouse gases we're chucking into the air causing global warming - but once this global warming thing gets in full swing, quite possibly combined with depleting our oil resources, using up all the fish in the oceans, general pollution and over-population, and hey, maybe even a nuclear war.... Well, we're not all gonna survive it, ay? We'll have crazy weather patterns and less land due to the sea levels rising - so ultimately we die off, and then the good old plants and sphagnum mosses go back to producing their coal, the phytoplankton use carbon in their shells and take it down to the bottom of the sea.... basically, once we're extinct, earth'll be just sweet on it's own (though it would've still lost LOADS of it's biodiversity, as the millions of species we've driven to extinction can't just raise back from the dead...)

Answer 5

Totally disagree. The earth is warming up day by day and with the polar ice melting, the ocean levels would rise. With increased population and decreased land space, and the higher temperatures, it would be survival of the fittest and no Ice Age....

Answer 6

Yes there will be another ice age. There is a well established geologic history indicating a 100,000 year cycle of ice ages, as well as a "mini" ice age within the past 25,000 years. Even with global warming (the fact of which I am not convinced, but that is another question) there will be another ice age.

Answer 7

Totally agree. The world warming up will actually increase this. Currently our climate is regulated by the constant movement of our major oceans,. Melt the icecaps and then this movement will stop, throwing the entire world out of whack.

Answer 8

One there is not any info of a god and China did no longer make each and every thing. immediately they make many stuff because of the fact they're the worlds best production facility yet they even have not made each and every thing.

Answer 9

According to the historic cycle of ice ages, we are about due for one now, however, because of global warming, it is not happening (yet).

Answer 10

Who Knows.

You will never get a unanimous yes from a group of scientists,
so how do we know who to believe?
