Impact of Global Warming on Water Resources

The impacts of global warming on water resources are as follows:

If the change range of weather and climate exceeds the upper or lower limit of normal fluctuation, extreme weather and climate events will occur, and the occurrence of extreme events is often accompanied by greater social impact. Taking precipitation as an example, excessive precipitation will bring storms and floods, endangering the safety of houses, land, farmland and even life. Too little precipitation will bring drought, affect crop growth, and even drink water for people and animals.

Under the influence of climate change, the global climate zone is changing. The main feature is that the ascending movement in the tropical area is strengthening, and the sinking movement in the subtropical area is also strengthening. Simply put, there is more precipitation where there is more precipitation, while the precipitation in subtropical arid areas is decreasing. In addition, the atmospheric humidity is also increasing and getting wetter and wetter.

The cause of global warming

1, the factor of population explosion

The rapid increase of population is one of the main factors leading to global warming, and it also seriously threatens the balance between natural ecological environment. With such a large population, the amount of carbon dioxide emitted by itself every year will be an amazing number. In this way, the content of carbon dioxide in the atmosphere will continue to increase, and the greenhouse effect of carbon dioxide will directly affect the climate change on the earth's surface.

2, atmospheric environmental pollution factors

The increasingly serious environmental pollution has become a major global problem, and it is also one of the main factors leading to global warming. The research on global climate change in 2 1 century has clearly pointed out that the temperature of the earth's surface has been rising since the end of last century.

3. Factors of marine ecological environment deterioration

The change of sea level is on the rise. According to the prediction of relevant experts, the sea level may rise by 50 cm by the middle of the next century. If no measures are taken, it will directly lead to the destruction and pollution of fresh water resources and other adverse consequences. In addition, a large number of toxic chemical wastes and solid wastes produced by land activities are continuously discharged into the sea, and major oil spill events in seawater are the main factors leading to the destruction of seawater ecological environment.
