Some of the specific effects of Global Warming



Although there are many causes of global warming, there are also many effects. One effect is that the global average temperature will increase. The second effect is that the sea level will rise. Other effect is that the extreme weather events will increase and diseases will spread of. Now I am going to talk about the rising in sea level.
The main reason of rising sea level is the raise of temperature which caused by global warming. Before 3000 years until the 19th century the sea level was nearly steady and increased from 0.1 to 0.2 mm/yr. But in 1900 It was rising at 1 – 2 mm/yr. In 1992 the level increased at 3 mm/yr specified from satellite altimetry. Some reports show that Lohachara Island in the Sundarbans in Bay of Bengal, was the first island maintained by rising sea levels that caused by global warming, and this was in December 2006.
