Water Loss In California

By: Kyler Evancho

Water to Life

All humans and animals need water to survive. About 70% of the Earth is made up of water. Most of Earths water is salter water, but it cannot be used to drink. The salt water is providing too much salt which can cause Dehydration, or even death. Fresh water makes up 2% of water on Earth. Fresh water is mostly used to grow food to feed the worlds population increases, the demand for the fresh water decreases. A larger portion of the fresh water we use is being wasted by inefficient supply of fresh water. Our water sources are also being polluted by human waste and other harmful chemicals from other plants. But Global Warming which is the result of releasing harmful chemicals into the atmosphere, and is also diminishing fresh water sources. Climate changes have changed extreme flood, droughts and streams. In many certain places Global Warming is causing

bad droughts which are resulting in large loss of animal and human lives. The water is so scares in certain areas that countries are starting to fight/go to war over it. Stuart A. Kallen stated, "The availability and control of fresh water supplies are issues poised to define life in the twenty-first century." (Paragraph 12)

The Map of the California Drought

This map is the map of the California drought. The Yellow means Abnormally dry (D0), The Yellowish Orange means Drought-Moderate(D1), The Orange means Drought-Serve (D2), The Red means Drought-Extreme (D3), and the Dark Red means Drought-Exceptional (D4).

California Drought is the most in at least 1200 years

According to a new study by the researchers, the drought that California is experiencing now is the worst one in over than 1200 years. The researchers show that the current drought is driven by reduced though not unprecedented precipitation and also recorded the high temperatures. With the effects of global warming being more visible, it did not take the researchers long to record the drought to settle in. Using tree rings analysis, researchers at Woods Hole oceanographic Institute and the University of Minnesota reconstructed California's temperature and precipitation history back to 800 A.D. Overall they found no less than 66 drought periods, lasting 3 to 9 years. None of them were as severe as what California is experiencing since 2012.

Enviornmental Changes

Drought is very hard on the environment. Changes occur, some more visible then others that occur over time. In a drought vegetation is visibly dry, stream and river flows decline, water levels in lakes and reservoirs fall, and the depth to water in wells increases. As drought persists, longer-term impacts can emerge, such as groundwater level declines, land subsidence, seawater intrusion, and damage to ecosystems. Unlike the immediate impacts of drought, however, long-term impacts can be harder to see, but more costly to manage in the future.

West Niles increase due to the Drought

The proportion of mosquitoes infected with West Nile virus is at the "highest levels ever," stated by Dr. Ron Chapman, director of the California Department of Public Health. By the end of 2014, the state had recorded, 798 human cases, the most since 2005, more then the number recorded in 2011. As a result 29 have died.

The experts say that an increase in stagnant pools as streams slow to trickles, along with a lack of water in general, may be major factors.

“A lot of water in nature becomes more stagnant. ... And stagnant water draws mosquitoes ,” stated by Dr. Dean Blumberg, an infectious disease specialist at UC Davis Children’s Hospital. Water sources have become crowded due to the drought, making it easier for the virus to spread between species.
