Global Warming

Global warming is one of the world’s biggest problems. Global warming is the raising of the average temperature of Earth's climate system. Global warming gives a lot of problems for a living thing. These are some of the global warming’s impacts:

First, the raising of sea levels around the world. When the temperature of the atmosphere increases, the temperature of the ocean surface layer also increases. As a result, the volume of sea water will increase due to the effect of anomalous water and the sea level also higher. In addition, as a result of global warming, the polar ice had melted (especially around Greenland). The melting ice also increases the volume of sea water on the earth. During the 20th century, sea levels around the world has increased about 10-25 cm. Scientists have also predicted that in the 21st century sea level will continue to rise about 9-88 cm.

Second, unstable climate, during the process of global warming, the northern part of the earth will heat up more quickly than other areas. This causes a lot of icebergs melt and the land in the area will be smaller. Ice floating in the northern waters would be reduced. As a result, a region that was experiencing light snowfall, maybe someday will not experience it again due to global warming.

Third, the extinction of a large number of species, one of the examples of endangered animal is polar bears. In 2006, the population of polar bears in the world is only 25,000 tails. So, they are categorized as endangered animal. Polar bears use ice floes as the foundation for hunting seals. With the global warming, the sea of ice in the North Pole is melting faster and impact on polar bear hunting. If they continue to fail to obtain food, they threatened to starve to death because they do not have the energy to hunt for food. 

Responding to the impact of global warming, we should prevent global warming by saving the use of energy such as turning off the light when we do not use it. We also can do a million trees planting.
