Water and Climate Change

Water is our main medium for sensing the impact of climate change. In many places, water supply is becoming increasingly unpredictable, and an increase in flood rate can damage water supply sites and sanitation, potentially polluting water sources.

In some areas, drought exacerbates water shortage, which adversely affects people's health and productivity. Enabling sustainable water and sanitation services for everyone is an important climate change mitigation strategy in the coming years

As the temperature rises, extreme and unpredictable weather conditions deteriorate, it is expected that the supply situation and distribution of rainfall, snow melting, river, groundwater will be affected and water quality will further deteriorate. Low income communities that are most susceptible to tap water impact may be most affected.

More floods and severe droughts are expected. Changes in water supply volume have also been shown to affect health and food security, which has been shown to cause refugee dynamics and political instability.

Water plays an important role in alleviating and adapting the effects of climate change around the world. Necessity to design a sustainable agricultural economic system that mitigates climate change, protects itself from extreme impacts, and adapts to unavoidable climate change, taking comprehensive consideration of the flow of water, biosphere and the environment there is.

The distribution of water after climate change can change greatly. Soil is an important part of the water circulation (or water circulation) - its balance is also affected by climate change. We know that climate change will affect our lives and the places we live. The current infrastructure such as buildings and roads almost certainly changes according to new climatic conditions. Overall climate change has a great influence on soil function and therefore great influence on future use of soil.

Climate change just beginning to be understood 40 years ago worsened water pollution. Climate change is a change in water. When the water temperature is high, toxic algae are likely to breed in rivers, lakes and bays. More frequent and intense rain will cause more pollution to flow into rivers and streams of cities. In the already dry western part, the drought condition means that water, fish, wildlife and human beings in rivers and streams will decrease in the water. Politics is also the culprit. The Environmental Protection Agency (EPA) has been limited by the increasingly hostile parliament, especially over the past 15 years. Interests of strong polluters such as the United States Agriculture Bureau Association and oil and gas companies have successfully influenced several members of Congress to support the weakening of serious water purification protection. The water purification law has not been updated for nearly 30 years, EPA's budget and the number of staff are shrinking every year.

Clearly, water is essentially related to climate change. Climate change exacerbates water-related disasters such as floods and typhoons. Examples of increased hydrologic cycles include more frequent and serious droughts in Africa and parts of Asia, more intense rainfall events in Europe, more floods and landslides, and higher tropical cyclone intensities I will. The relationship between water pollution and climate change is less obvious. Sheahan gives some examples: rising temperature can change the sedimentation rate of pollutants and rate of accumulation in aquatic organisms; increased rainfall may promote pesticide leaching. Sewage scrubbing; if the submerged land is contaminated, more water pollution will occur as the risk of flood increases. Therefore, climate change can increase the severity of water pollution.
