Chapter Two The Review of the Related Literature Salinity and temperature are two common important factors apart of the water quality. Water everywhere is influenced by these two factors, even freshwater though the salinity is generally lower relative to other bodies of water. These two factors have certain ranges of values that generally remain constant. The normal ranges of these values are within the tolerance range of the directly affected living organisms. When one factor - temperature increases and then salinity decrease/increase to a significant level the effects would dramatically affect nearly all those living organisms. People would be affected as well when the salinity concentration increases. Excessive amounts could signify negative relationship between water pollution and health outcomes (Wang, Q., & Yang, Z., 2016). Salinity is not simply table salt, it contains other salts as well; salts are an ionic compound with many different varieties of other chemicals within them (Knowlton, 2001). With climate change and global warming in this generation there is an obligation to first find clarification of salinity and temperature, the significance, impacts, and the possible correlation between salinity and temperature The environmental changes in regards to the Earth’s natural temperature has seen a slow continual rise. The rise of temperature would not only have an effect on the water, it could possibly affect other water quality factors which implies a stronger
World War Two resulted in a chaotic destruction that overwhelmed Europe. These feelings of dismay are concisely summarized in Ruta Sepetys’ Salt of the Sea.. An impactful quote states, “war had bled color from everything, leaving nothing but a storm of gray.” The war in 1945 had drained any and all feelings of hope and spirit out of European people. In it’s wake, the war left a cloud of devastation and despair. Florian and Joana have to overcome this war, their fate, and guilt in order to return to their past selves and survive their journey in a German and Russian warzone.
When salinity increases, warning signs appear in the landscapes of the affected areas. These warning signs include things like sick and/or dying trees, declining vegetation, colonisation of tolerant weed-like plants, bare patches where vegetation has died and saline pools in creek beds. These show that the ecosystem is being affected and at a high rate.
(Salton Sea Symposium, 1998) However , the condition of the Sea has drastically changed and so has the amount of healthy living organisms in the Sea. By the 1980�s the water level rose greatly and gave way to abandoned businesses, deteriorating structures and empty beaches. The above was due to the fact that evaporation is the only outlet to the Salton Sea , in fact 1.35 million acre feet of water is lost each year , thus increasing its salinity even more. The salinity of the Salton Sea has increased to 45,000 parts per thousand or 45 PPT; the Pacific Ocean is currently 35 PPT.
The rise of sea levels are projected to increase warmer waters from one and a half to two degrees in Central North Pacific in 2050, 1.9 to 2.6 degrees in Northern Islands, and also two to five degrees in the Caribbean at the end of this century. This rise of temperature decreases the life of ecosystems in the ocean and resulting in less freshwater for
Irrespective of its cause, the impacts of climate change include more frequent and severe weather, higher death rates, dirtier air, higher wildlife extinction rates, and higher sea levels (IPCC, 2014). Although each of these impact areas are significant and worthy of further discussion, it is the ramifications of sea level rise that brought me to discuss climate action today.
This approach becomes particularly problematic in the case of climate change as reduced water supplies likely in arid and semiarid regions where salinity is an issue work against such a response.
Another factor of ascending sea levels is the increase in temperatures (3). Eissa and Zaki implies that “a considerable number of many species will be threatened with a continuous increase in sea levels to a certain point that the animal or species could become extinct” (The impact of global climatic…” 2). Sea levels are rising at very accelerated rates, and until the water keep rising, they will become very harmful to the human population and many marine organisms. However, increasing temperatures is one of the main factors of climate change. Johansen insists that “the warming of the world’s oceans has not only affected the animals who live above the surface, but also the ones who live below” (“Marine Life…” 1). Increasing temperatures are mostly caused by many human activities such as the release of fossil fuels emissions and greenhouse gases. The two main processes that cause increasing temperatures are Climate Change and the Greenhous effect. These can be very harmful to the marine population and permanently extinct them. According to recent studies, NOAA has discovered that seawater temperatures are increasing by about 0.1 Celsius, and many organisms confronted with this change could be in great danger (NOAA 2). In addition to increasing temperatures and sea levels rising, another factor would be ocean acidification. Global Issues portrays that” ocean acidification is caused by substantial amounts of carbon dioxide which is caused by greenhouse emissions” (Climate
Due to Climate Change, the temperatures are increasing and there is a rise in sea
During the 1990s scientist were able to collect 5,000 different salinity profiles. From their findings they were able to estimate a 20 percent increase in freshwater. Due to this increase there was a rise of fresh water by 8,400 cubic kilometer, which can be compared to the volume of fresh water and ice that is released in lower latitudes from the Arctic each year.
I think that if the temperature of the water changes it would affect the surrounding land drastically because everything thing is used to that temperature already.
The Water Education Foundation published an article on excess salinity that is in the water here in the valley. Our bodies need some salt to absorb water to be able to survive. Too much intake of salt can be a problem, and that is what is happening here in the Central Valley. “Excess salinity – that which is greater than the standard set to protect beneficial uses – poses a growing threat to food production and drinking water quality.” If there is no solution to the problem, it means that California will lose significant portions of prime agricultural land which provides food for the state, the nation and throughout the world. In a March 2009 study, The Economic Impacts of Central Valley Salinity, the University of California, Davis reported that if salinity increases at the current rate until 2030, the direct annual costs will range from $1 billion to $1.5 billion, with income impacts to the Central Valley between $1.2 billion and $2.2 billion.
It has been observed through various researches that in the last century, average temperatures across the globe increased by over 1.3°F with an increase of more than two times in the Arctic. (Bates, Kundzewicz, Wu, & Palutikof, June 2008). The results of climate change can also be seen in changing precipitation patterns, increases in ocean temperatures, changes in the sea level, and acidity and melting of glaciers and sea ice (USEPA, 2014).
Water pollutants introduce abnormal conditions (harmful chemicals, changes in water temperatures) into water bodies, disrupting existing ecosystems and can potentially contribute to reducing biodiversity in that affected area – one of the effects of water pollution. For example, the discharge of heated-up water from thermal and nuclear power plants into a river can cause problems for aquatic organisms, which are fairly used to specific temperatures. The increase in water temperatures could increase their metabolic rates and hence their need for food. This could eventually lead to the depletion of food sources in that water region and in turn cause a reduction in species population in that water region. Besides thermal pollution, water could also be polluted via the entry of acidic substances into the water bodies through rivers, seas and oceans. The effects of water pollution by this process, known as
From a scientific point of view, the author describes and substantiates the existence of global warming and also observes the potential effects it could result in. These include of rising sea levels, shifted climate patterns, increased threats to infectious diseases, extreme global temperatures, and coastal erosion. But ultimately, the report informs readers that the degree to which global warming affects life on Earth primarily depends on our decisions.
One of the most serious effects of global warming, as it continues to intensify, is the increase in the ocean levels. Thermal expansion of the ocean and glacial melting are likely to cause a .5 to 1.5 meter rise in the ocean level by the year 2100. As the ocean level rises and if no protection is provided, many freshwater supplies could be jeopardized. Tens and possibly hundreds of millions of
