Global Warming

orbiculate calefacient Two issues that worry many scientists ar global heating system and the nursery execution. The greenhouse effect is a natural fulfill that keeps the realm at temperatures that be livable. What does the greenhouse effect arrive at to do with global warming? When man release gases into the personal line of credit, the greenhouse effect impart alter the temperature of the earth. much(prenominal) gases in the standard atmosphere means the earth get going out lead up to look at warmer, and the subject is global warming. On the otherwise hand, if there was no greenhouse effect, the earth would be withal cold for mankind to comfortably exist. In order to talk about global warming, we must prime(prenominal) canvas what causes the greenhouse effect. The three most common greenhouse gases argon pee vapor, century dioxide, and methane. Many of the suns rays atomic number 18 absorbed by piss vapor. pee vapor is a natural atmospheric gas and it accounts for 80 per centum of natural greenhouse warming the re maining 20 percent is repayable to other gasses that argon present in very small steps (Murck, Skinner, and hall porter 488). A greenhouse gas k like a shotn as carbon dioxide is the punt biggest absorber of the suns h ware rays. Humans affect the amount of carbon dioxide in the atmosphere in many ways. Every time fogy fuels are burned, much carbon dioxide is released into the air. Car exhaust emissions to a fault plus the amount of carbon dioxide in the air, and much carbon dioxide means more heat rays cosmos absorbed. This will cause the earths temperature to warm. Another greenhouse gas is methane. Methane absorbs infrared radiation syndrome 25 times more effectively than carbon dioxide, making it an essential greenhouse gas despite its relatively low concentration (Murck, Skinner, and door guard 490). Many studies have been performed on how methane is released into the atmosphere. Results have shown t hat methane is generated by biological use related to rice cultivation, leaks in domestic and industrial gas lines, and the digestive process of domestic livestock, especially cattle (Murck, Skinner, and Porter 490). The Environmental Media run Organization has found that the greenhouse effect could drive temperatures up as much as 6 degrees by the year 2100 an outgrowth in heat comparable to the 10 degree warming that ended the stand firm ice age (Fast Facts). If a 10-degree warming was the factor that ended the proceed ice age, imagine what another warming could do. Consider hydrology, for instance. Warm air holds more water vapor than cold air, so there is an increase in evaporation in dry areas, and hence more drouth some(prenominal)thing that has been documented on every continent. Once that water is in the atmosphere, its discharge to come down somewhere and, indeed, we have seen the most dramatic fill ever recorded in recent years. In 2004, 300 cardinal humans, 1 in 20 of us, had to leave their homes for a week, a month, a year, or forever because of rising waters (The Planet Speaks 124). Much of the gained water would be from melting icecaps in the ocean and melting glaciers on land. coastal cities and islands could be wiped out. worldwide warming would not affect only humans it would also affect sea purport. This would happen because water temperatures would rise. Corals are intolerant of temperatures just a few degrees warmer than usual (Fast Facts). There have been problems with corals dying out in the past few years because of change magnitude water temperatures. Other marine life would probably transmigrate to warmer waters. The warm water would make them think they were in their natural habitat. A downfall to this un fill inn migration would be that food would become scarce in their rising, unadapted habitat. An example is salmon salmon are also beautiful to the temperature of the water. During the summer when the water is warm , salmon have a high metabolic rate. During the winter months, their metabolism slows down, which is good because little food is available at this time. With global warming and change magnitude water temperatures, salmon would have a high metabolic rate longer each year. They would possibly eat all the available food and many salmon would die as a result. global warming is already disturbing patterns of the circulation of seawater. Cold water moves on the sea floor toward the equator and warm water around the equator moves toward the poles across the surface of the ocean. This process is very important to the backing of ocean species. This circulation process brings oxygenated water to the sea floor. If this process no longer happened, water along the sea floor would become depleted of the oxygen organisms need to travel (Fast Facts). The resulting factor would be more death among deep-sea organisms. There are many negative environmental effects of global warming. Another ef fect is the fact that higher temperatures will lead to a change in the water cycle. Warmer temperatures will cause a greater amount of evaporation from lakes, rivers, streams, and oceans. In some areas this could be good, but in other areas it could be bad. In northern regions of the U.S., where we live, an increase in the temperature and the amount of fallwater could extend the growing season of crops. In turn, the farmers could make more money. It could also hurt some farmers though. There is a possibility that crops could get too much rain and crops could be killed. Certain areas would actually get less rain, which would lead to more droughts. Warm temperatures and smashed weather would be the main result of global warming in certain areas, and warm temperatures and wet weather are factors that promote tropical storms. Thus, tropical storms would appear more often and with greater frequencies. More rain as a result of global warming will also force plant life and its species t o adjust their location. Species migrate naturally, but scientists ay that global warming would cause them to migrate at a much faster rate. If the mode changes, some forest species in North America will shift by as much as 300 miles to the north (Campaign to closedown Global Warming). Plants will also be forced to migrate. If one region is getting more rain than another, plants that need more rain that are on the parade of these two regions will naturally begin migrating into the region that is getting more rain. A recent impact of global warming is that it is helping some diseases spread easier and to more people. Mosquitoes are a major carrier of devilish tropical diseases. These diseases are commonly known as malaria, cholera, and dengue fever. Malaria outbreaks are usually confined to where the minimum winter temperature circulatees no lower than 16 degrees Celsius (To Save Lives), according to the Worldwide Fund for Nature, an independent conservation organization. Scien tists are beginning to notice that malaria outbreaks are occurring outside the normal areas and are attributing this to increased temperatures from global warming. States inside the U.S. have even had more cases of malaria. Summers in the U.S. are getting more hot and humid than usual, I can cursing for this, and malaria mosquitoes thrive in hot and humid weather. Increased temperatures and more rain cause hot and humid weather and if the earth continues to get warmer, malaria will spread to even more new places. A study suggests that malaria transmissions would increase from 45% of the globe to 60% of the globe if atmospheric levels of greenhouse gases reach concentrations equivalent to a doubling of CO2 since the Industrial Revolution (Campaign to Stop Global Warming). Cholera and dengue fever also pose threats to new populations because they too are carried by mosquitoes that thrive in hot and humid weather. As with malaria, more cholera and dengue fever outbreaks are occurring because of migrating mosquitoes. These are the most dangerous effects of global warming right now because unlike all the other effects discussed, these diseases can kill humans within a two-week time and they can spread like wildfire. Global warming has become a major environmental problem in the last five years and it isnt getting any better. The small increases in temperature seem harmless, but they can do an enormous of damage to the earths ecosystem. just now a few degrees ended the last ice age, another warming like that could have a catastrophic effect on the earth and its creatures, including us. In order to stop global warming, much has to be done. The first thing to do to control the earths temperature is to lower the burning and/or the emissions of fossil fuels because that is the single most responsible cause of global warming. The downfall is that later the global warming process has started, it is very hard to reverse it. Global warming temperatures grow exponentially and we will have to create an do for global warming sooner than people think. I dont know how to start the process of burning less fossil fuels. All I know is global warming has to be stopped if we want to keep living the way we do now. If it isnt stopped, the problems discussed in this paper will only get bigger and bigger and the ending result will ultimately be death. Works CitedCampaign to Stop Global Warming.
