31. What Will Happen if Global Warming Continues? The impact of global warming has been divided divided into four aspects. 1. Impact on sea levelGlobal warming will cause melting of the icebergs at both the north and south poles of the Earth, which is one of the major causes of sea level rise.

A direct impact on sea level rise in the following areas: (1) lowland flooded: (2) The coast is eroded. (3) Increased salinity of surface water and groundwater affects urban water supply. (4) groundwater level rise. (5) Tourism compromised (6) Affecting the lives of coastal and island residents (1/3 of the world’s population) and threatening them. If the polar ice caps to melt, economically developed and densely populated coastal areas will be swallowed by the sea, the Maldives, the Seychelles and other low-lying island states disappear from the ground, Shanghai, Venice, Hong Kong, , Tokyo, Bangkok, New York and other major cities seaside. As well as Bangladesh, the Netherlands, Egypt and other countries will also be fateful.

2, the impact on the flora and fauna the climate is the major factor in determining the distribution of biomes, climate change adaptation in different species in an area and change the competitiveness of different populations of internal ecosystem. Natural flora and fauna, especially plant communities, may have suffered bad luck because they could not adapt to the speed of global warming . Past climate change (such as ice ages) had made many species disappear, the future climate will allow certain species to disappear in some areas, and some species from the human warming obtained benefits, their habitat may increase, competitors and natural enemies may also be reduced.

For example, oranges, which used to be the northern boundary of the country in the 1970s, have also been planted in some cities. However, in a winter heavy snowfall, the trees are frozen to death. But now the orange trees on campus are all good.

In another example, Chinese alligators live only in Xuancheng, Jing County Nanling so narrow and small areas, if the north boundary northward, Chinese alligators may naturally extinct. This is from the local area of the provincespeak. 3, the impact on agriculture ??Global warming is exerting more and more on agricultural production. Previously, Lu Houquan, an expert on ecological and agrometeorology at the National Meteorological Center, said that the high temperature of the drought in Sichuan and Chongqing last year and the high temperature in most of the autumn and winter crop areas have a great impact on crop growth.

So, crop yields and food crops will be affected in large numbers and changes in the spatial (latitudinal) distribution of the biozones and biomes will be observed in greater mass. Global warming will also increase natural disaster such as high temperature, heat waves, tropical storms and tornadoes. 4, the impact on human health, human health depends on good ecological environment. Global warming will become the main factor for a human health .

Extreme heat will become the next century human health problems become more frequent, more widespread, mainly reflected in increased morbidity and mortality, especially malaria, bubonic filariasis, schistosomiasis, hookworm, cholera, meningitis, kala-azar , dengue fever and other infectious diseases will endanger tropical regions and countries, some mainly occurs in tropical regions of the disease may spread to the mid-latitudes as the climate warms.
