    Will there be no ice-age in future?

    Those students of science who have studied Geology and especially the evolution of Earth very well know that there were long duration of ice ages from time to time on Earth when a large portion of Earth was covered with sheets of ice. Many species perished during that time and only the few who could struggle against the odds could survive.

    As per the scientific studies, we are now out of the last ice age which engulfed Earth about 3 million years ago and ended about l l,000 years ago. Now scientists and researchers believe that due to the global warming, which is essentially due to more presence of greenhouse gases in Earth's atmosphere, the next ice age may not come or may be delayed significantly.

    Seeing at a micro scale we are not feeling any change in the severity of cold in the winters and especially in the current winter there is unprecedented snow fall and severe cold in many parts of the world.

    So the apprehended global warming, if it were so, should have made the winters less severe. But it is not happening.

    Can you give your opinion or comments on this paradox?

    Recently I have read somewhere that the ozone layer is getting filled slowly. This is a positive indication. However still a long way to go.
    This winter has come very late. In fact, up to Pongal we never felt cold in Hyderabad and Andhra Pradesh. But after that, the cold is very severe. But this is for a very few days. The reason for this cold also was attributed to the formation of Low-pressure regions in the Ocean.
    In the 1970s and 1980s, the winter season was very long. But slowly the duration is decreasing and the duration of summer is increasing. The rainy is also reducing. Temperatures are increasing. So we can say that the ice age may not come or may come after a very long time.

    As the time gap is so big it is difficult to understand the phenomenon of ice ages. The present global warming is a real threat to the Earth and its inhabitants.

    Due to this uncertainty the scientists can not predict the next ice age whether it will happen or not.

    Thoughts exchanged is knowledge gained.

    The ice age is the extensive presence or expansion of ice sheets in both northern hemisphere and southern hemisphere.
    However, global warming is a real threat to this ice age but with absolute surety, nothing can be said about the ice age which seems uncertain even for scientists.

    It's really difficult to predict the behaviour of the environment. Because of wide-ranging pollution, the weather has changed all over the world and it is true that because of the greenhouse effect, there is a confusion about the next ice age. There are many factors contributing to the changes in the environment and we do not know what is going to happen in the long run.

    At times, there is a severity of cold at a particular place, the next year you may find it moderate. The entire scenario is changing on a daily basis. It is understood from these changes that there is a great imbalance in the environment and the scientists are finding it hard to pinpoint the exact reason behind the peculiar behaviour of the atmosphere.

    In my opinion, scientists also just predict they are not sure what's going to happen in future but one thing is sure that air pollution is causing a temperature rise which ultimately is causing melting of glaciers and the result may be severe and may cause most of the snow to melt. Many of the species of plants and animals who used to survive in low temperatures have extinct and many more are endangered and may extinct at any time. So in a nut shell, we have to reduce air pollution.

    I read a study that contradicts what you say. Ice age, like tectonic events are predictable because they follow cycles. The next ice age is likely to occur in next 1000 years. I find it possible too. Here are the reasons causing Ice ages;
    1. Volcanic eruptions
    2. Continental shifts
    3. Tectonic collisions
    4. Global cooling with composition difference in gases
    5. Nuclear explosions

    Although global warming is definitely prevalent, this isn't the first time earth has warmed this much. So Ice ages are definitely possible.

    The stronger a light shines the darker are the shadows around it.
