Every year the U.S. spends more than $ 20 million to buy fossil fuels. This country is to let a quarter of global greenhouse gases, most important of these gases is carbon dioxide that is released by fossil fuels. Global warming is a problem all over the world for years. Some of the countries and people who claim to be only vaguely concerned about the reason, because they were unaware or ignorant of the matter. Roger Revelle, oceanographer, has helped the audience shouting to the problem. When you do not get much feedback to his cause, has criticized the governments of the various light-hearted way. He has called global warming “great geophysical experiment.” He said: “This experiment was designed to be downloaded into the atmosphere as carbon dioxide as possible, add a couple of other harmful gases, and see what happens.” Recently, a number of countries are passing laws to prevent overheating of the fate of the world.
Even with the setting of new rules and regulations, the earth continues to warm every year. Minimal effort to reduce emissions of greenhouse gases, especially carbon dioxide from burning fossil fuels, increase the speed and intensity of global warming.
The most visible effect of global warming is a climate change in recent years. Many people do not know the cause of global warming and changes in all types of weather. Global warming means that the size and strength of weather conditions to increase. As the oceans warm up, the intensity of hurricanes, and extends the power of destruction. In addition, many coastal cities and regions have recently experienced floods caused by melting polar ice caps. Perennial ice cover in the region fell by nine per cent each year. Over the past thirty years, more than ten Finnish records set at the highest temperatures in summer and winter. Drought and forest fires have been occurring more frequently dramatically in the last century. All these effects have been reported directly to the release of greenhouse gases.
Another area affected by global warming in the animal kingdom and nature. Number for each species of animals has decreased each year due to changes in the environment difficult. Such as melting polar ice caps, all the creatures that live there are left without protection. For example, when the seal housings are melting, the number of seals has declined. Events in the spring, migratory birds, such as mating, the eggs and return from sleep mode was about 5.1 days earlier than they were fifty years ago. Early onset of these events and to prove that the Earth is getting warmer every year. More proof of global warming, there is evidence of many animals as they migrate from the equator to carry out. Although this change is the presence of creatures, butterflies, moths and mosquitoes are located far away from their habitat. Although the butterflies do not cause any known problems with the environment, mosquitoes bring malaria.
This deadly disease has been dangerously expanded to new regions around the world. If the world continues to warm, this issue, with many others, continue to grow.
A third type of evidence of global warming can be found in plants. The vegetation in a different area while the climate in that area. Throughout many parts of the world, 7 days before flowers bloom and trees are raised 10 days prior to the time since 1900. As growing seasons ranging from very wet to very dry, agricultural growth can not adapt. In some recent years, growing areas are flooded and dried two. Due to the depletion of the ozone layer, many crops can not survive. Another problem is the movement and the rise of allergens. Carbon in the atmosphere allows the plants through photosynthesis to go faster, allowing allergens to grow in number. The evidence found in nature, it is clear that global warming is a huge problem.
The combination of various actions, and in some cases, the activity is not sufficient to cause global warming in the modern world. The main reason for global warming is running on fossil fuels, which releases carbon dioxide into the atmosphere. The carbon dioxide with other greenhouse gases, methane, nitrous oxide, and chlorofluocarbons, is the reason for the greenhouse effect. This effect is an increase in harmful gases are released in large quantities. These gases are not only built to keep the heat in the atmosphere, but thin layer of ozone. Some areas have been so thinned that the gas is the presence of ozone holes. These holes allow damaging ultraviolet radiation from the sun’s dangerous to enter the country. UV rays are the main cause of skin cancer. As the world continues to increase the amount of pollutants each year, the number of skin cancers is increasing.
Because it releases carbon dioxide into the air, the combustion of fossil fuels is environmentally harmful practice. Carbon dioxide can be absorbed by the salt water. If the water is cold, it can hold more gas. Unfortunately, with global warming, ocean temperatures increased. Rising temperatures, more carbon dioxide released. This vicious circle will continue to happen unless scientists can not occur. In particular, gasoline or petrol, is a major source of carbon dioxide emissions of these compounds. Gasoline contains hydrocarbons, which emit carbon dioxide when burned. This reaction is unfortunately inevitable. The only solution is another source of fuel. Carbon dioxide, when released, will last up to 100 years in the atmosphere. It is the most abundant gas absorbs heat, in addition to water vapor, which is not considered a greenhouse gas because it rains back to earth in a continuous cycle.
Mauna Loa Observatory to measure the carbon dioxide emissions of the car on a daily basis since 1958. Since the investigation began, the atmosphere is significantly increased level of 47 ppm. Carbon dioxide makes up about half of the root causes.
Although carbon dioxide significantly affect the environment, greenhouse gas emissions have a significant effect in the atmosphere. Methane, the most important gases harmful coming from cattle, rice fields of asphalt, coal, oil and rice. Over a period of only ten years, methane absorbs heat thirty times more carbon dioxide. Another greenhouse gas, nitrous oxide, is about 180 years, and absorbs heat 200 times more than carbon dioxide. Nitrous oxide comes from microbes in soil that is found in fertilizers. Slash and burn agriculture and the burning of some fossil fuels also emit nitrous oxide. The last chlorofluorocarbons greenhouse gas, has 400 years in the air and maintains 16, 000 times more heat. Chlorofluorocarbons flee the different cooling systems. The combination of these four gases results in the conservation of quantities of heat.
Around the world, different nations were to participate in order to help prevent or slow down global warming. On February 3, 2007, French President Jacques Chirac, a new plan to prevent global warming. He said: “It is our responsibility to the future of humanity demands it..” Forty-five countries excluding the United States, joined him in his efforts. Al Gore is very involved in global warming and the greenhouse effect, he argues Jacques Chirac and plans to help you. As the biggest contributor to global warming, the United States contends that, unfortunately, the voluntary reduction programs.
The issue of global warming affecting nature, people and economy. For some, global warming is not concerned because they feel they are not affected. Although not realize the global warming affects everyone, especially for future generations. Scientists simulate mathematically the planet’s weather systems. His complex equations, called general circulation models (GCMs) are so complex and involve many elements that can take days to resolve. Conservationists to ensure that the dangerous combination of floods and droughts will increase significantly in the next century. The standard sea level has increased annually for some time. Some say that if the Earth continues the way it is on, then 95% of the Great Barrier Reef will disappear by 2075. It is estimated that the glaciers in Glacier National Park could melt by 2030 and 37% of all species could disappear by 2050.
The researchers directly connect the disease to global warming. Exposure to a different climate and animal diseases are increasing, and possibly brutality. Experts agree that skin cancer is a high rate of growth may be due to holes in the ozone layer. As these holes grow in size and number, the number of patients will increase. In addition to natural questions, and Heath, the world economy is in danger. Ross Gelbspan Boiling point of the author, a book on global climate change, global warming, told the audience of his book in 2004, said:. “Climate issues at the end with holes in the global economy” The study may show that if current weather patterns continue, the cost of insurance will increase dramatically in coming years. Gelbspan is one of many writers and scholars to look ahead to warn the population that is to come, unfortunately, most people do not listen.
When people try to get others involved in the action, a common problem that arises is the lack of motivation. Many people do not realize that if they can slow the process of rapid heating, there will be more time to develop alternative energy sources such as nuclear fusion. Holland and Germany, and several small countries have recognized this opportunity and committed to a 80% reduction in all greenhouse gas emissions. If the United States would engage in a program like this, so the greenhouse effect would be much slower than does today. World, especially the United States have to take action now. Stephen H. Schneider from the National Center for Atmospheric Research (NCRA) said: “When we find global warming has destroyed the soil’s ability to feed its population, it will be too late to do much.”
In conclusion, the world needs to highlight a greater effort to prevent global warming, emissions of greenhouse gases quell the earth every day. If countries make a greater effort to reduce global warming, predestination of the world can not be reached until several years later. Individually, people can recycle fuel-efficient vehicles, carpooling, and simply give out. As told by Elmer Robinson, the director of the Mauna Loa Observatory, told the talk of global warming, “The real enemy is us.”
