Global Warming = Disasters

Global warming is a threat for humanity. It endangers human species because it brings disasters. Global warming causes bad things. The first one is Extreme weather. Can’t you see the unpredictable weather around you? Once, the sky can be so blue that it is so hot during the day. But the following day, it can be cloudy then the rain falls heavily, even followed by storm or thunders. Like what Thomas Knutson and Robert E. Tuleya of NOAA stated in 2004, Warming induced by greenhouse gas may lead to increasing occurrence of highly destructive category-5 storms. In 2008, they found that Atlantic hurricane and tropical storm frequencies could reduce under future greenhouse-gas-induced warming.
Extreme heat can bring drought that affect the whole part of the ecosystem. Plants died, and then the animal, and finally the human because they will not have food to eat after plants and animal do not exist anymore. It increases the number of people who die directly on a given day for many reasons, for example people with heart problems are vulnerable because one's cardiovascular system must work harder to keep the body cool during hot weather, heat exhaustion, and some respiratory problems increase. This extreme heat can also trigger fire in the forest. The fire burning produces gases that we do not want such as carbon monoxide. This gas is very harmful. It may bring disease to our lungs, damage our respiratory system. The worst is there will be desertification if the drought happens in a long time.
The heavy rain can cause flood which sometimes take along victims. It sweeps away everything it passes. The animal, plants, wood, buildings, vehicles, and of course human. Like we can see in the television, many people die because of flood. Changing patterns of temperature and rainfall would also cause a shift in the distribution of dengue and malaria-carrying mosquitoes, likely exposing millions more people to such diseases by the end of the century.
The heat caused by global warming also melts the polar ice. By doing so, global warming makes the sea level rises. For example, the Greenland and the Antarctic ice sheets. he estimated total ice melting rate over Greenland is 239 ± 23 cubic kilometres (57 ± 5.5 cu mi) per year, mostly from East Greenland. Under the IPCC Special Report on Emission Scenario (SRES) A1B, by the mid-2090s global sea level will reach 0.22 to 0.44 m (8.7 to 17 in) above 1990 levels, and is currently rising at about 4 mm (0.16 in) per year. This rising sea level will make the land become narrower and there will be constricted area for human to live.
