Ice Age

I recently watched a TV program that discussed a coming ice age, and that perhaps human kind wasn't entirely to blame. It had to do with the water in the Atlantic Ocean off of Greenland. Something to the effect of that it cooled off quicker than normal, and that temperatures were dropping. Has anybody ever heard of this theory? Perhaps I am just having issues, but I thought the big craze was that the planet is increasing in temperature?

i have heard that the next ice age would come regardless of human action. it is like a big cycle. i think humans have only sped up the process.

That's what this documentary mentioned...that we had sped it up, but that it was inevitable. Though, this is supposed to take place thousands to millions of years from now.

Supposedly, we were in a period of cooling, now we're in a period of warming to be followed, yet again, by a period of cooling. I think it's very interesting how the ocean and the wind patterns can affect all of this.

that would suck.........i hate extremely cold weather.........how long would it be till the ice age would end?

and since there would be an ice age.............why do we have to care about the greenhouse effect?

I know this theory. Although, I first heard about it because of the study of "civilization" ending droughts. Basically its about global weather patterns.

An increase of warm air/water being carried by the atlantic gulf stream causes the polar cap to melt. The melting polar cap causes the northern water temperature to lower. Lowering water temperature causes the gulf stream to "veer" south. The change in the gulf stream causes northern temperatures to drop. Drop in temperatures could trigger an ice age, in the very least it is a "mini ice age". This decrease in air temperature causes ice caps to re-freeze. Re-freezing of the ice cap allows ocean temperature to increase. Increase of northern ocean temperature "pulls" the gulf stream back in position. And we are back where we started.

Global warming causes a change to the frequency of this cycle.

I am interested in the current drought in the south west U.S. as it could be a sign that the "raising temperature cycle" prior to the melting ice cap is about over.


Edit: to answer this question

why do we have to care about the greenhouse effect?

Simply, the green house effect wins unless the planet finds its own way to remove the increased level of Carbon dioxide in the atmosphere. Since it is not likely the planet can correct this without "removing the cause", we should worry about it.

Hello from frenchie
Does anyone see the day after tomorrow?
I think all will arrive sooner than we expect

www.nasa.gov...
I have seen also several tv programm in france
i think that in 20-30 years the polar regions will have melted
so the ice age will arrive

I have always found this site to be very interesting as to theories and current events indicating the return of an ice age. They occur around every 13,500 years according to geological records. And we are in that window.
I don't stand a chance being in Alaska.

Good Luck,

Record low temperatures in 18 states yesterday.
See daily listing of record low temperatures across the United States.
If we had had record high temperatures in 18 states, it would
have been plastered across the front page of almost every Sunday paper
in the country. But what did you see in today�s papers? Nary a peep.

Record low temperatures in Winnipeg. Daily high temperatures in Winnipeg
averaged only 19.5C (67.1F) during May, June, and July, breaking the old record set in 1950.
The normal daily high average for these months is 22.5C (72.5F), says a report issued by
Environment Canada issued on August 3, 2004. Temperature records began in Winnipeg
in 1874. (Thanks to Robert Hotchkiss for this info)

�Will compasses point south?� No, this headline doesn�t come from some supermarket tabloid, it comes from the New York Times and it backs up what I�ve been saying for years � that we are headed for a geomagnetic reversal.

yay just like that movie with giant storms and people freezing and people running into mexico!

I think it would be wicked a bit upset that if it was to happen then im screwed because i will of been past my prime by then so id have no chance if it happens in the next couple of years then maybe i cud survive a little while longer. id love civilisation to come crashing down life would be alot simpler survival of the most ruthless

Think if you did survive & we went back into living tribe like you might be the wise man/women who tells every1 about when you had these magic boxs called computers

If it does happen then i dont think we shud worry as a spiecies we survived the last one so we will get though it.i dont really think the human race can be extinct from anything but are own hand now.

Actually, they say life would be rosy along the equator nice temps in the 60's and 70's places like North America south of Canada whatever lattitude that is 40 or something like that would be a wall of ice. Below that would be cold

I live in Utah, and I have to agree...it's been a cooler year this year. Last year though..*shudder* the hottest July on record... 16 consecutive days at or over 100 F. However the winter helped out in a big way, just not enough to pull us out of drought. But, are we ever out of drought? LOL doesn't seem like we ever have in my lifetime!

Yes well,
Good morning Amber Be sure to visit this www. it will more than likely enlighten you on your questions.

Sincerely,

i wonder wot the land mass would look like? because if more water is frozen then that means that more land will be exposed wouldnt it? probably be able to walk across from england to france then make my way down to the equator where there nice temps are better take me shades

we are already in the ice age.we are in the "hot" part of the ice age that was there even since north and south america joined together

Just a few thoughts on plate tectonics and ice ages. I'm researching the subject as we speak. I am particularly interested in PANGAEA. There seems to be a theory that suggests that generally, there are several land masses at high altitudes that precludes a freezing period. That seems to be the case on Earth right now, no? There seems to be more land masses in the North than in the South.

No Son,
Water expands when it freeze's so there would be less land mass.

Do you think that a Waterworld scenario is likely?

In an Ice age? I dont think so, all the water would be frozen. But if global warming happens first, then the ice age then yes.

Yeah that was a random thought about this cooling and warming. My brain = in havoc today!

I live right on the lake Michigan, looking at it, its hard to believe it was all ice at one time. Its so big. I think that warming will raise the water level and then freeze.
