In modern life, one has to face many critical problems. Global warming is the most controversial problem. It is not also scientific problem but also common problem because it affects our lives directly. In recent researches, scientists have proved that global temperature raised 0.60C ± 0.2oC from 1901 to 2000 and 0.74oC ± 0.150C from 1956 to 2005, so the rising temperature in the world has mostly happened for the recent 50 years.

According many scientific researches, global temperature increases by 0.740C in comparison with one in 1850. Temperature in two poles increases twice as much as the average temperature of the Earth. Because of the domino effects, Global warming causes many environmental problems. The first significant problem created by climate change is ice melting. When temperature rises, polar ice melts, water in oceans and rivers stretches and evaporates fast and then it will change rain level in the world, it makes ice melt much fast. Icy area decreases critically (2.7± 0.6 % each year in this decade). Many buildings, houses, offices, oil pipelines, gas pipelines are built on permafrost. Ice melting will make many people in dangerous situations or lose their house; we will lose many important constructions. Ice melting also affects sea level. Satellite photography indicates that the global sea level raised 3.1 ± 0.7 mm from 1993 to 2003. Now, there are many archipelagos that have sunk into sea such as in Pacific Ocean. Millions of will lose their houses due to encroaching upon land. And this phenomenon is already occurring, as seen when 11000 habitants in Tuvalu archipelago were relocated to New Zealand after rising sea level swarmed their homes. Sea level rises with air pollution and greenhouse effect, the Earth absorbs more and more heat from the sun so it will rain more. The rain changes, it makes some regions are predicted to experience serious droughts but others will be extreme flooding. The weather’s condition will be severe. Elbe River...
