Global warming is one of the major current problems that the world is facing today at large. Because of the contributory negligence of the world the problem of global warming arose. The ignorance and exploitation of the nature at the hands of the people all over the world caused global warming to occur. This was one of the problems which could have been easily avoided had the proper steps been taken in time. But now it is already too late and the ill effects of the global warming have started showing up endangering the existence of every existing species. The most drastic effect of the global warming that the world has witnessed so far is that of the rising sea levels. 

Because of global warming sea levels have raised considerably thus causing a threat to the islands and other coastal areas. As a result of sea levels global warming is still on the rise and is rising every year. This has caused a threat of sinking of the islands and other coastal areas into the sea. Several problems are already being faced due to rise in sea levels because of the global warming. The sea levels have raised to such an extent that any further increase in the sea levels are going to destroy the coastal areas and thus destroy all forms of life that exist there. Because of global warming the temperature of the earth has increased dramatically which has caused the ice to melt. This melting ice is flowing in the seas and oceans thus increasing the sea levels. Earlier, when there was no global warming at sea level were normal and the sea showed particular behavior in terms to tides, waves, etc. But now no particular pattern is seen in the behavior of the sea due to which sea calamities are highly unpredictable. Even if there is control over the global warming at sea level is not going to decrease so easily. 

Several scientists have said that because of the global warming at sea level rise, in the next few decades, shall become the reason for destruction of the whole earth's crust. Soon under the effect of global warming at sea level will rise to an extent that the water from the seas will flood the continents and swallow them. Because of the global warming at sea levels will rise and thus put an end to the very existence of the human beings and also to that of other species. If there is less global warming sea levels will rise slowly thus giving more time to us for finding proper solution for the problem.
