Question
1. Give a review of the Hydrologic Cycle as it applies to water in your region with at least four different places water can be found. One Fifth of the world does not have access to clean water. How might this change in the future? Would your area be at risk? How?
2. If climate change continues to cause problems, might there be a difference in worldwide temperatures? How could increased temperatures directly affect the water cycle? Find one example of how this has affected humans in at least one of the following areas: a. overall population growth, b. dangerous geologic hazards (flooding, tsunamis, erosion, etc.).
3. Find a current news article that helps to describe one of the issues of surrounding water and pollution in your state or region. Summarize the article in 50-100 words. What issue is this related to in our readings for the week?
Explanation / Answer
1.The circulation and storage of the water through out the earth(on, above and below the surface of the earth).The Hydrological starts from evaporation from water bodies on the surface of the earth (rivers,ocean, lakes etc) then precipitation of the water by rainfall,snow fall etc.Water storage in my region are lakes, ground water ,evaporation from plants( evapotranspiration) ,rivers.
One fifth of the worls doesnot have access to clean water.All ready my country India is sufferring from water crisis major in Shimla and delhi.This is due to over exploitation of waterbodies, waterpollution adding to the climate change.Yes my area is already experiencing water crisis.And due to increasing freshwater demands both by population , industry leading to a demand expected to outstrip supply by 40% in 2030
2.The U.N. Intergovernmental Panel on Climate Change (IPCC) predicts a rise in global temperature (between 0.3 - 4.8 degree Celsius or 0.5 to 8.6 Fahrenheit) by the end of 21st century.
Increased temperature would directly lead to drying out of the water bodies such as rivers, fall in ground water level thus leading to severe droughts in some areas.
Effect of climate change and increased temperatures in a)population growth is directly responsible Increased population is directly responsible for increase in emission of green house gases into the atmosphere.A study of the relationship between increasing population and global warming determined that the carbon consumption of just one child can produce 20 times more greenhouse gas than a person will save by driving a high-mileage car, recycling, using energy-efficient appliances and light bulbs, etc. Each child born in the United States of America will add about 9,441 metric tons of carbon dioxide to the carbon consumption percentage of an average parent.
b)Global warming has increased the rate of ice melting from the polar ice caps thus increasing global sea level causing major floods in many costal areas.Tsunamis are a result of tectonic upliftment or downfall of in the oceanis crust causing a sudden disturbance in the oceanic water creating massive amplitude waves.
Increasing water level would lead to the process of coastal erosion causing to the destruction of sea coasts, river bank destruction etc.
3.Article Name- Scientific american,World Has Not Woken Up to Water Crisis Caused by Climate Change
Summary- Water scarcity can lead to conflicts between nations and the world is still do not know the problems of water crisis and future probems due to climate change.IPCC study shows a global rise in temperature by .3 to 4.8 degree celsius. India will face direct consequences due to climate change such as severe droughts leading to Agricultral problems and food shortages.Fast developing countries leads to more consumption of water for hydropower plants and neuclear plants.To deal with the problems of water scarcity india needs to be more efficient on harness water more efficienty in industries as well as in agriculture as water is wasted in a large scale in agriculture as well as over exploitation of water and control of pollution of water bodies
