Climatic changes have been occurring for eons and cause for those changes has always been the variation of solar output. Present day changes in climatic conditions and temperature variations have been increasingly attributed to global warming. While the debate rages on about the value of global warming statistics and its relevance in climatic changes, it is worth mentioning that most of the damages that are attributed to global warming are in fact, destructive to the living conditions to the world.

Extreme weather conditions: Of late, in the last few decades, there has been an increase in climatic fluctuations. Many parts of the world are concurrently affected by droughts, bitter cold temperatures, torrential rains, heat waves etc. There is an alarming increase in the occurrences of such phenomenon. Climatic experts point out global warming statistics and inform us that is the cause. Non believers say that it is only now that such occurrences are receiving wide spread coverage but they have been occurring for centuries. Whatever may be the case, extreme vagaries in weather conditions, often within the same climatic areas have caused environmental concerns in the world.

Glacier shrinkage: Glaciers have been retreating for the past couple of years. Over the period of history, the glacier size increase has been cyclical but modern science has not been able to predict the patterns of this cycle. Whether the modern decrease in glacier size is due to climatic cycle or not, the environmental effects of this phenomenon are for real. Many glacier filled areas in the world are undergoing a radical change, in the process destroying many animal and plant life forms. A few years from now, we all will know if these changes are permanent or temporary but tight now global warming statistics indicate that this is a man made catastrophe that can alter the life cycle of the earth.

Greenhouse gas accumulation: Global warming statistics conclusively prove that there is an increase in accumulation of green house gases in the atmosphere. Greenhouse gases are formed due to burning hydrocarbon fuels and in the past 50 years, the emission of these gases has increased exponentially, in direct proportion to industrialization and development of the world. These gases do get accumulated in the atmosphere and global warming experts attribute the increase in temperature of the world to these gases. The increase in temperature by itself is a debatable point but accumulation of gases is an unnatural phenomenon that is bound to affect the living conditions of the world at some point in time.
