people say global waming will cause an ice age?

Question

how is that global warming will cause another ice age when the tempureture is going higher.... and if global warming will cause another ice age, can u give me some links ligit articles to read?

oh yea , about that "the day after tomarrow", thats a science fiction movie. its not real.

Answer 1

The user above is right, a good and self-explanatory example is the movie "the day after tomorrow".

Global warming will cause an ice age because on due to the higher temperatures, glaciars on the poles will melt, and therefore, they could cover and freeze the Earth, can you imagine how many longitudes of glaciars exist? Enough to make a great flood.

OF COURSE it's science fiction, it had never happened, but what happens in the movie is probably very alike to what will happen to Earth if we dont do something to reduce global warming.

I just wanted to set an example for you to notice that global warming and another "ice age" are really related

The movie presents myriad scientific mistakes (like the ones you could find in the link below), but some things are not completely wrong...

Answer 2

Yes, it's true that the geologic record shows that the various "Ice Ages" tend to follow rather abrupt up-ticks in global temperature. Read this very complete comprehensive summary (see link) of the history of research on the cycles of global Ice Ages. About halfway through is an explanation of the temperature rise that seems to occur BEFORE the onset of a widespread glaciation. There's a chart beside it showing the temperature fluctuations in a typical cycle.

By the way, the "Day After Tomorrow" movie is a grossly unrealistic exagerration of how quickly devastating global events related to climate change would occur. There are currently very serious climatic problems developing worldwide, particularly in Arctic regions but there could not be the huge and immediate dramatic catastrophes like 200 foot tsunamis and instant glaciers and icebergs as they showed in the film.

Also, I apologize in advance for the ignoramuses who are likely to weigh in on this topic arguing about the issue of to what extent the climate shifts are a natural cycle or due to human impact. Evidence suggests it's a little of both and we may never know the absolute truth.

Your question was a good one and sticks to the known patterns of observed cycles and hard science (not political arguments and paranoid agendas, which have no place in scientific inquiry and only distract from dealing realistically with the actual problems that climate shift is already causing.)

Answer 3

Global Warming is a trojan horse for Socialism, wake up Americans. Global warming is at the fore front because politicians found how to use a new platform to get re-elected. The world leaders use it because they found ways to make money at it. This is a made up problem just like Global Cooling in the 1970's. Wake up people. I agree we need to be more efficient with our resources, and we should fine and jail companies who are dumping into our rivers maliciously. I want to stop the raiforest destruction, but to say that global warming is a serious man made issue and we need to destroy the American economy and bow down to the rest of the world certainly does not float my boat. Follow the money on this one and you will see that it is all for political gain and grant money for those scientists who profit off of the government if global warming stays at the front of the issues. Look deep into the Keoto (sp?) Treaty, first of all they took jets to a non-central resort location. Not very environmentally concious. THen in the parameters of the treaty they have a clause that makes it so you can buy or sell polution credits. This is all about shifting wealth and breaking down the United States. This is painfully obvious, just look at peoples agenda. The earth's mean temperature has risen .6 degrees C in the past 125 years. Greenland's icecaps have gotten colder in the past 10 years. The Scientists who do not gain anything on their posisition will tell you that the earth has a natural progression and this is what we are seeing. The UN report is made up of POLITICIANS not a good spread of scientists. THere are as many or more scientists who believe that man in NOT the reason and it is over hyped, but their voice is not heard in the LIberal Mainstream Media. This issue is 99% political, and an attempt to make the USA a socialist nation, and eventually communisim. WAKE UP AMERICA, IT IS TIME TO BE AMERICANS. FOR THE PEOPLE BY THE PEOPLE. STOP THE LIES

Answer 4

Its like a chain reaction.
Higher temperature lead to more POLAR ice melting.
More ice melting leads to lower salt concentration in the ocean which can upset the flow of ocean currents.
If the ocean currents change their course or stop flowing, they will not be able to transfer heat from the middle of the earth to the poles of the earth.
This will cause the temperatures at the poles to drop very fast making everything freeze.
The new ice will reflect more light into space (like a giant mirror) causing things to freeze even more.
Before you know it, the world looks like a giant ice cube.

Answer 5

worldwide Warming is pretend. worldwide climate substitute, which isn't waiting to be altered by potential of people, is what's going on. we at the instant are not at present close to to and ice age, yet in fact that they do take place on occasion. Oh, and picture approximately this. If the ice caps soften what's going to take place? you're able to be able to think of that the sea will overflow, nicely you're lifeless incorrect. think of roughly this. positioned ice in a tumbler, then fill it to the brim with water. Wait approximately an hour and flow back and see that the water did not overflow. you're able to be able to think of, nicely yeah the ice displaced the water, yet interior the ice caps the ice is above the water. nicely, it style of feels God planned this complete element out. What happens to water whilst it freezes? IT EXPANDS. whilst it melts, it contracts (shrinks). It shrinks on the perfect ratio because of fact the ice it extremely is above to what's below. 10:ninety. each and all of the ice ought to melt and not something might take place to the sea point. the only result may be much less sparkling eating water.

Answer 6

In Britain at least, changing sea temperatures could switch off the Gulf Stream which raises our temperature considerably compared to similar latitudes. If the Gulf Stream was switched off we would have the same weather as Northern Canada.

Questions for Al Gore
By Dr. Roy Spencer
25 May 2006

Gore's Inconvenient Truth....

Dear Mr. Gore:

I have just seen your new movie, "An Inconvenient Truth," about the threat that global warming presents to humanity. I think you did a very good job of explaining global warming theory, and your presentation was effective. Please convey my compliments to your good friend, Laurie David, for a job well done.

As a climate scientist myself -- you might remember me...I'm the one you mistook for your "good friend," UK scientist Phil Jones during my congressional testimony some years back -- I have a few questions that occurred to me while watching the movie.

1) Why did you make it look like hurricanes, tornadoes, wildfires, floods, droughts, and ice calving off of glaciers and falling into the ocean, are only recent phenomena associated with global warming? You surely know that hurricane experts have been warning congress for many years that the natural cycle in hurricanes would return some day, and that our built-up coastlines were ripe for a disaster (like Katrina, which you highlighted in the movie). And as long as snow continues to fall on glaciers, they will continue to flow downhill toward the sea. Yet you made it look like these things wouldn't happen if it weren't for global warming. Also, since there are virtually no measures of severe weather showing a recent increase, I assume those graphs you showed actually represented damage increases, which are well known to be simply due to greater population and wealth. Is that right?

2) Why did you make it sound like all scientists agree that climate change is manmade and not natural? You mentioned a recent literature review study that supposedly found no peer-reviewed articles that attributed climate change to natural causes (a non-repeatable study which has since been refuted....I have a number of such articles in my office!) You also mentioned how important it is to listen to scientists when they warn us, yet surely you know that almost all past scientific predictions of gloom and doom have been wrong. How can we trust scientists' predictions now?

3) I know you still must feel bad about the last presidential election being stolen from you, but why did you have to make fun of Republican presidents (Reagan; both Bushes) for their views on global warming? The points you made in the movie might have had wider appeal if you did not alienate so many moviegoers in this manner.

4) Your presentation showing the past 650,000 years of atmospheric temperature and carbon dioxide reconstructions from ice cores was very effective. But I assume you know that some scientists view the CO2 increases as the result of, rather than the cause of, past temperature increases. It seems unlikely that CO2 variations have been the dominant cause of climate change for hundreds of thousands of years. And now that there is a new source of carbon dioxide emissions (people), those old relationships are probably not valid anymore. Why did you give no hint of these alternative views?

5) When you recounted your 6-year-old son's tragic accident that nearly killed him, I thought that you were going to make the point that, if you had lived in a poor country like China or India , your son would have probably died. But then you later held up these countries as model examples for their low greenhouse gas emissions, without mentioning that the only reason their emissions were so low was because people in those countries are so poor. I'm confused...do you really want us to live like the poor people in India and China ?

6) There seems to be a lot of recent concern that more polar bears are drowning these days because of disappearing sea ice. I assume you know that polar bears have always migrated to land in late summer when sea ice naturally melts back, and then return to the ice when it re-freezes. Also, if this was really happening, why did the movie have to use a computer generated animation of the poor polar bear swimming around looking for ice? Haven't there been any actual observations of this happening? Also, temperature measurements in the arctic suggest that it was just as warm there in the 1930's...before most greenhouse gas emissions. Don't you ever wonder whether sea ice concentrations back then were low, too?

7) Why did you make it sound like simply signing on to the Kyoto Protocol to reduce our greenhouse gas emissions would be such a big step forward, when we already know it will have no measurable effect on global temperatures anyway? And even though it represents such a small emission reduction, the economic pain Kyoto causes means that almost no developed country will be meeting its emission reductions commitments under that treaty, as we are now witnessing in Europe .

8) At the end of the movie, you made it sound like we can mostly fix the global warming problem by conserving energy... you even claimed we can reduce our carbon emissions to zero. But I'm sure you know that this will only be possible with major technological advancements, including a probable return to nuclear power as an energy source. Why did you not mention this need for technological advancement and nuclear power? It is because that would support the current (Republican) Administration's view?

Mr. Gore, I think we can both agree that if it was relatively easy for mankind to stop emitting so much carbon dioxide, that we should do so. You are a very smart person, so I can't understand why you left so many important points unmentioned, and you made it sound so easy.

I wish you well in these efforts, and I hope that humanity will make the right choices based upon all of the information we have on the subject of global warming. I agree with you that global warming is indeed a "moral issue," and if we are to avoid doing more harm than good with misguided governmental policies, we will need more politicians to be educated on the issue.
