The lowlands were flooded.
(2) Coastal erosion?
(3) The salt content of surface water and groundwater increases, which affects urban water supply. ?
(4) The groundwater level rises.
(5) Tourism is threatened.
(6) Affect the life of coastal and island residents (accounting for13 of the world population) and make them threatened.
2. Effects on plants
(1) Animals and plants in nature, especially plant communities, may adapt to the speed of global warming, and thus encounter bad luck. Past climate change (such as the ice age) made many species disappear. Will the future climate make some species disappear in some areas?
lose
(2) Climate change can lead to significant changes in biota and its spatial (latitude) distribution.
3. Impact on human health?
(1) Human health depends on a good ecological environment.
(2) The morbidity and mortality are increasing, especially malaria, lymphatic filariasis, schistosomiasis, hookworm disease,
Infectious diseases such as cholera, meningitis, kala-azar and dengue fever will harm tropical regions and countries, some of which are mainly?
Diseases that occur in tropical areas may spread to mid-latitudes with climate warming.
(3) In the process of warming, the earth will face more extreme weather and extreme climate events. Such as persistent drought, peak heat wave, extreme rainstorm and flood, coastal areas affected by super typhoon, extreme storm surge disaster and so on.
(4) Affected by extreme weather events, secondary disasters such as lack of drinking water, reduced grain production and epidemic diseases have increased. Affected by climate change, some oases may disappear.
? 3. Impact on agriculture
(1) The distribution of temperature and precipitation in a year is the main factor to decide what crops to plant. The change of temperature and precipitation caused by temperature will affect the yield of food crops and the distribution type of crops.
(2) After the global temperature rises, the stability and distribution of world grain production will change greatly.
