What impact will global warming bring?
1. Global warming will lead to the increase or decrease of temperature and precipitation, change the spatial distribution pattern of hydrothermal resources and affect climate change.
2. Global warming leads to rising sea level and inundation of coastal lowlands. On the one hand, global warming makes the polar continental glaciers melt, and a large number of glacial meltwater enters the ocean; On the other hand, global warming makes the sea water expand due to heat, both of which push the sea level up and flood coastal lowlands and some islands.
3. Global warming intensifies the occurrence of natural disasters. For example, in the second half of the 20th century, the frequency of rainstorm in the middle and high latitudes of the northern hemisphere increased by 2% to 4%. At the same time, due to global warming, extreme weather phenomena such as El Niñ o, La Nina, cold wave and drought occur frequently.
4. Global warming will lead to changes in the original ecosystem of the earth, and changes in climatic conditions will lead to changes in the entire ecosystem, including the possible extinction of some species. For example, corals in the ocean are very sensitive to the change of seawater temperature, and global warming has caused many corals to die on the Great Barrier Reef.
5. Global warming has an impact on the main production fields of human beings, especially on agriculture, forestry, animal husbandry and fishery.
