An Ice Age brought on by global warming was the scenario depicted in the movie THE DAY AFTER TOMORROW. While the science on which the movie based has been called into question, there may be some merit in the theory that global warming could cause an Ice Age.
Why is Europe’s climate comparitively milder than other places at the same latitude? Alaska and Greenland, both the same distance to the North Pole as Europe, are covered with ice and permafrost while most of Europe is not.
The ocean currents called the Gulf Stream bring warm waters up to Europe from the Caribbean. This water brings warmth to the countries in its path. Cooler water from Europe feeds back into the loop and causes the water to flow back to the Caribbean in a continuous cycle.
If an Ice Age occurs, it will likely be due to the melting of polar ice. This will dump large quantities of cold, fresh water into the ocean. It would disrupt the Gulf Stream and cause the cooling of many areas that now have milder climates. The return flow of cold water from Greenland, which goes back to the Caribbean, has already showed a weakening over the last 50 years. There has been a twenty percent decline in the amount of current flowing in this direction. It stands to reason that the warm waters returning from the Caribbean have also decreased in volume. The change would not be gradual. This is a phenomenon that takes place rather quickly. Perhaps it does not happen as fast as depicted in THE DAY AFTER TOMORROW. However, it could happen within a few short years.
A slowing or stoppage of the Gulf Stream would affect the entire earth. Observations have been made of current data and historical information gleaned by studying the ocean and the lands around it. With all the information at hand, it appears that it is indeed possible that global warming could bring about a modern Ice Age.

Hamish Fraser asked:
Global warming is the issue worrying one and all environmentalists around the world. It is now becoming quite imperative that be stop global warming fastest so that the effects of warming that have affected earth adversely are reversed and we are able to live a little happily than before.
There are many things that can be done on a personal level to stop global warming. Firstly, we should know how much heat and pollution is created by every family, this pollution is producing green houses gases and accelerating the process of global warming. One of the answers to stop the warming is that we should consciously start planting trees not just around us, we also ensure that the lost rainforests and tropical forests are restored back to their normal volume.
These tropical and rain forests work as lungs for the entire world, creating oxygen and purifying the air. Therefore, when these are cut off, it can harm the entire ecological system of the Earth, this means there will be very less oxygen and lesser trees to provide us with oxygen. It will make us susceptible to many breathing disorders and other health problems.
We need to stop global warming, is that the scientists have been telling us for quite sometime now. The reason is obvious, if not stopped or reduced, the large snow mountains at the poles will start melting, and this will lead to a sort of catastrophe. World’s major population stays at the sea side. Once the ice starts melting it will increase the sea levels several feet above what it is now. It has been already reported from the countries near the North pole that the rising sea levels has caused them to relocate their homes a little farther.
Rising sea levels will mean destruction of huge numbers of human beings, animals, property, industries, flora and fauna. This will also mean flooding and increase in salinity of available ground water. This again is potentially harmful for human health. This will also mean millions of people will have to move from near the sea to interiors. This would also mean loss of life and loss of millions of dollars.
If you feel strongly against global warming you should try and make contributions to organization you feel has been working actively for the purpose to stop global warming. Your small financial contributions can make a lot of difference. Your contributions can provide boost to these organizations to find man power and monetary power to buy land and convert it from arid dry deforested land to a good sized forest.
You can also stop global warming at your personal level. You can try and plant as many trees around your home. You can also try and use minimum electricity, you can try and avoid usage of sprays, non-green products which increase toxic waste on the Planet. It is necessary to stop global warming so our children can live healthy and long lives.
