Recommended: Effect of global warming on agriculture
With increasing global surface temperature in addition to anthropogenic interference, the possibility of intense as well as frequent climate disasters are indefinite. Droughts are often caused by human activity, and they result in devastating conditions. Socioeconomic droughts occur when there is water stress caused by food production, diminished supplies, greenhouse gas emissions, land use change, and more. Developed and undeveloped countries are affected internationally. Lake Urmia, located in Northwest Iran, was once the second largest saltwater lake on earth; however, in the past 15 years, 20 man-made dams have been operating in Urmia’s basin. Lake Urmia has decreased in size by about 80%. The lake’s hypersaline desiccation will increase …show more content…
These salt storms are a prime example of human induced changes which lead to substantial environmental degradation (AghaKouchak). Moreover, a large sum of individuals believe that earthquakes are considered to be all natural; nevertheless, this is not always the case. Hydraulic fracturing, also known as ‘fracking’, is the action of applying liquid at high pressure into subterranean rocks that forces already existing fissures to expand giving individuals the opportunity to extract oil or gas (Gibbins). The U.S. Geological Survey discovers that, “29 project sites where earthquakes were induced by fracking itself, 36 sites where quakes were induced by post-fracking wastewater disposal, and 12 sites with temblors induced by unspecific oil and gas wastewater disposal.” (Gibbins). Furthermore, one outcome of global warming is the immense levels of water vapor in the earth’s atmosphere (Union of concerned scientists). This sequentially creates conditions such as heavier precipitation in the form of intense rain and snow storms (Union of concerned scientists). With storms increasing in intensity, flooding becomes a very large concern for
Water shortage in arid and semi-arid regions and declining its availability to a crisis ...
Water is the foundational basis of life on Earth. Ecosystems, society and humans are completely dependent on it, and as the world population continues to grow, there will be more mouths to feed, and those people will need water to continue their daily lives. However, shortages and poor management leads to the destruction of natural habitats and human suffering. Desertification of land in China is ever-increasing, turning green, lush land into desert. However, this is due mainly in part, because of human activity, and global warming (Wang, Yang, Dong, & Zhang, 2009). The United States could experience a crisis similarly to China’s, but for now they have averted such a catastrophe, because of heavy regulation of water. Though there are water shortages in many parts of the world, it is unwise to export water from the Great Lakes to those regions. Two major reasons why diverting the Great Lakes is a terrible idea, one: it allows for waters wars to start on the basis of who is allowed to access it and for commodification purposes. Two, diverting water on such large scales could have cataclysmic effects on the local residents as well as the environment.
Hydraulic fracturing, also called fracking, is a technique designed to release the gas and oil from shale rock hidden underneath earth’s surface. The term fracking itself is referring to the point at which the shale rock is broken open by a high-pressure mixture of water, sand, and chemicals. Oil and gas fracking can be dangerous to the environment and also to humans. “In 2011, energy company Cuadrilla suspended test fracking operations near Blackpool, in Lancashire, after two earthquakes of 1.5 and 2.2 magnitudes hit the area. A subsequent study found it was highly probable that shale gas test drilling triggered the tremors” (BBC). Although these tremors were too small to do any damage above ground, this was still a test drill. If an oil rig were to become operational, the tremors could increase in magnitude, causing significant damage both above ground and underneath the earth’s
In today's global economy, energy is one of the most crucial and sought after commodities. Who supplies it and how much they supply determines how much influence they have over other countries as well as the global economy. This is why hydraulic fracturing is currently such an important and controversial topic in the United States. Hydraulic fracturing, more commonly known as "fracking" or hydrofracturing, is the process of using pressurized liquids to fracture rocks and release hydrocarbons such as shale gas, which burns more efficiently than coal. This booming process of energy production provides a much needed economic boost, creating jobs and providing gas energy for Americans. The efficiently burning shale gas reduces carbon emission from electricity production plants, reducing carbon footprints on the environment. However, the process of hydraulic fracturing uses millions of gallons of pressurized liquid, which contains toxic chemicals, and some of this water is left over undealt with. The air near fracking sites is often also polluted and unsafe for nearby community residents. Injecting millions of gallons of water laced with toxic chemicals into the rock thousands of feet deep can cause earthquakes, causing a safety hazards for all nearby areas. Hydraulic Fracturing makes rare natural gases easily attainable, boosting the economy and reducing carbon emissions. However, the negative side effects such as contaminated water and air, make hydraulic fracturing a process that may not be worth the benefits.
There are concerns that fracking could be the causation of earthquakes. In areas where fracking operations occur and earthquakes are not the norm, there has been instances of seismic activity. For example, before 2011, the last seismic activity experienced by small town in Ohio named Youngstown was in 1776, but in a span of months during 2011, more than 100 instances of seismic activity ranging from 2.7 to 3.9 on the Ric...
"Welcome to the new Venice," McKenzie joked as salt water surged from the sewers. ---- Michael J. Mishak, Associated Press June 7, 2014 Over the years, Earth has been through numerous catastrophic events; such as, the KT dinosaur extinction, but none of these events are comparable to the +7.1 billion metric tons of greenhouse gas emissions that are being produced in the United States of America yearly.(Tonto.eia.doe) As Al Gore once stated in his book, Earth in the Balance, “the process filling the atmosphere with carbon dioxide and other pollutants – is a willful expansion of our dysfunctional civilization into vulnerable parts of the natural world” (234). These greenhouse gas emissions will pollute our atmosphere causing catastrophic events, therefore we our obligated to help reduce and maintain greenhouse gas emissions before they cause these destructive effects on Earth. In order to discuss theses catastrophic events, it would be more efficient to discuss the greenhouse gas emissions and greenhouse effect individually.
Ever since the process of hydraulic fracturing—or fracking—made its entrance to the oil industry, issues and problems surrounding the process have become a common occurrence. Fracking is the controversial process of horizontal drilling (see fig. 1), where millions of gallons of water mixed with sand and chemicals are pumped deep into an oil well to extract natural gas from the earth’s crust (Ehrenberg 20). This practice has even been banned in some places (see fig. 1). The methane that comes out of the earth and the water used—called fracking fluid—has the potential to cause problems with local ground water supplies. Whether or not fracking is the cause of these problems, concern should be observed during the fracking process to reduce the chances of water contamination among residential areas.
It was a cold day in ‘Lake Abraham’.The water was frozen.People were asking ‘why are bubbles under the ice’.Until a photographer name Darwin wiggett said ‘don’t get to close.Why ask the people,Darwin said ‘you wouldn't want to be close to one if it popped.The ice bubbles can possible cause death,and burn your skin.
The use of fossil fuels has greatly increased the amount of atmospheric and oceanic CO2 to a point where it’s ruining the natural flow of the world; the earth’s temperature is rising. As a result, the polar ice caps are melting causing the seas to rise. With only a 1 meter increase in sea level the United States alone could lose over 10,000 square miles of land, and thousands of houses will be destroyed. The effects will be just as prominent around the world: many islands will become submerged, 17% of Bangladesh will be underwater, and tens of thousands of people will be displaced (“Global Warming” 3).
This creature can grow up to 7 plus feet and can weigh up to 300 pounds. They are rarely seen in the great lakes, however, this is their natural habitat. These fish often live on the bottom of the lake and often coast the shoreline. This particular type of fish tries to avoid salt water because they can get eaten by larger fish like sharks. This fish is typically solid dark brown in color with a bright white belly. The Lake Sturgeon was once apart of the major northern lakes like the Great Lakes, Hudson Bay, and the Mississippi River.¨ They also have been found in 19-20 different States. These fish are sometimes referred to as ¨Freshwater Monsters¨¨ (http://www.britannica.com/animal/sturgeon-fish) . The Sturgeon is a very large fish and it doesn't have many predators the only other large fish that can kill it is a large shark or killer whale.

CO2 emissions introduce many alterations to the earth’s climate that negatively affect humans. Some of these alterations include the shrinking of water supplies, which has become more and more crucial as the demand for water increases with the rapid growth of the earth’s population. This effect on the water supply has shown that it can in turn effect agricultural production. Major changes in food production as a result of climate change will cause food prices worldwide to increase, posing major economic challenges to people everywhere. Finally, there is the issue of increased incidence of natural disasters. Many climate and environmental scientists attribute the growing frequency of devastating natural disasters such as droughts, wildfires, and hurricanes to climate change. The last of these was the one that specifically affected Houstonians this past year with the Category 4, Hurricane Harvey, that tore through the city in late August of 2017. The ramifications of this hurricane were felt throughout Houston, dealing $125 billion dollars’ worth of damage and claiming 88 lives (Allen & Davis, 2017). Geert Jan van Oldenborgh of the Royal Netherlands Meteorological Institute was one of the central figures in noting that Hurricane Harvey and the torrential rainfall that came with it were direct result of climate change. The manipulation of ocean currents, and the retention of water in clouds caused by warm weather, both facilitated the production of the brutal tropical storm. Some estimates claim that the increase in rainfall at the hands of climate change were anywhere from 15 to 38 percent (jan van Oldenborgh, van der Wiel, & Sebastian, 2017). Van Oldenborgh noted that while the “likelihood of a Harvey-like storm was perhaps once in every 3,000 years in the past, now it’s once every 1,000 years or so”
“For most of the history of our species we were helpless to understand how nature works. We took every storm, drought, illness and comet personally. We created myths and spirits in an attempt to explain the patterns of nature (Druyan).” According to Fox, Drought came also be seen as a slow- motion train wreck. We still have a very short time to get the people off safely before the crash. This drought is causing long dry period in regions were rain fall is usually frequent enough. From there this drought is turning to more like a famine because the area in drought is so huge and is causing much conflict for the survival of the people (2011). These areas include Somalia, southern Ethiopia, and northern Kenya.
Many scientific studies also show increases in the intensity, duration, and extent of droughts, higher atmospheric temperatures, warmer sea surface temperatures, changes in precipitation patterns, and diminishing glaciers and snowpack. The bottom line is that causes of climate change, such as greenhouse gas emissions, will have to be minimized if people want to do as much as possible to solve the water crisis.

The problem of water scarcity has increasingly spread throughout the world as of yet, The UN reports that within the next half- century up to 7 billion people in 60 countries which is more than the whole present population will face water scarcity (Sawin “Water Scarcity could Overwhelm the Next Generation”). As well the demand for freshwater has tripled over the past 50 years, and is continuing to rise as a result of population growth and economic development. 70% of this demand derives from agriculture which shows the influence of water on food supply globally as well not just drinking water (Sawin “Water Scarcity could overwhelm the Next Generation”). But increasing water use is not just a matter of the greater number of people needing it to drink and eat; it also comes from pollution and misuse of water supplies, by either dumping or runoff of bacteria or chemicals into water. This also “causes other pollutions as well such as soil and air pollution, accelerating wetland damage and human caused global warming” (Smith and Thomassey 25). According to UN report, recent estimates suggest that climate change will account for about 20 percent of the increase in global water scarcity in coming decades.
