Global warming means the rising and increasing temperature on our planet. as the earth temperature is getting higher and hot, natural calamities changed its nature gradually. And due to this rising temperature natural disasters like floods, storms, hurricanes, raging forests fires and droughts become more frequent.

Human beings themselves damaging the ozone layer near the earth which provides safety to the earth's climate from ultraviolate rays of sun by producing fossils fuels, natural gas fuels, by cutting forests that results into the much hotter temperature.

Cutting down forests are being rapid in practice since last few years. People cut trees for agriculture purposes and to gain the good woods. On the contrary the replanting system is not satisfactorily enough. Forests play very important role to hinder the floods which has become frequent in different parts of the world in past few years just because of the global warming. Forest and plants produce oxygen and their absence would be the cause of more carbon dioxide in the air which our industries are producing from the fuels in the air. Carbon dioxide damages the ozone layer and become the cause of global warming.

Earth temperature on the global warming map is getting warm year by year. So far the rise in temperature is not very rapid but it expected to be much faster and frequent in next 50 to 100 years. More floods are expected to come as oceans will be more hotter and consequently glaciers melt, so the coastal areas will be flooded.

By control greenhouse gases we can make the process of global warming a bit slow. if we act properly as a precautionary measures we can slow the blow which will be devastating otherwise.

We should take care of the animals and trees, because only certain species of animals and trees can survive in hot environment. So we need to provide possible corridors for animals to migrate in their suitable environment. Same in the case of trees that we have to grow the plantation even more.

Glaciers are very important in global warming and their decline can be seen on a global warming map. As the temperature rise more, glaciers would melt rapidly. When glaciers melt, oceans' level would rise above. glaciers are spread 10^% on our earth. Glaciers contain 75% of fresh water. In 1990 the study about global warming said that if human beings would not change their usual lifestyle the global warming will reach more rapidly. According to the study sea level would rise 25 inches above in next century. If global warming would speed up it is said that sea level would be higher more than 10 feet by 2100.
