The Impacts and Solutions of Global Warming

The Impacts and Solutions of Global Warming
Climate The Earth is heating up! Climate models show that atmospheric temperatures will increase by between 1.5 and 4.5 C by the year 2100 if a ?wait and see and do nothing? approach is adopted. The global temperature increase since the last ice age (10,000 years ago) has been about 5 C. Temperature and precipitation patterns in the high latitudes of the Northern Hemisphere, which appear to be becoming ?more tropical.? There is less of a difference between daytime and nighttime temperatures, and rainfall tends to more often come in intense bursts. Oceans & sea level Their first concern of global warming is causing the rise of sea levels. The greenhouse effect and sea level rise
threaten the very heatof our existence ? B.Paeniu, PM of Tuvalu at the World ClimateSince oceans absorb more heat than land areas. The best-guess forecast of the ipcc for sea level rise is a global average of 3-10 millimeters per year. As more than 70 per cent of the world?s population live on coastal plains, the potential for massive personal, economic and physical dislocation becomes clear.. Part of this comes from the expansion of water, as it was getting warm. Apart from the widespread melting of mountain glaciers. About 17 percent of the rise remains unexplained. With a large number of the world?s cities in coastal areas, this is a significant problem. There are two major causes of rising sea levels. Firstly, extra water is produced when ice melts causing by warmer weather. Secondly, the natural expansion of Ocean water as it becomes warmer. The range of sea ice around both poles continues to shrink and melts. Even with the level of greenhouse gases present today, by the scientist around the world estimated that the earth may warm enough in the next 50 years or so to completely melt the sea ice located on the poles. Lands As warmer oceans cause more intense storms. Damage from rising seas is very diverse. Buildings and roads close to the water could be flooded and they could suffer damage from hurricanes and tropical storms. There are also effects on agricultural production and water resource. A slight increase of that would also be enough to make deserts hotter and drier or increased frequency of forest fires, or would melt a third or more of the world?s mountain glaciers. Since the mid 1980s an unprecedented number of intense fires have destroyed forests and homes across most continents For example: Sydney is ringed by fire as unusually prolonged hot, dry and windy conditions fuel more than 150 firestorms across the state of New South Wales. Trees whose seeds are spread by birds may be able to spread at that rate. But other trees and plants whose seeds are carried by the wind, nor such nut-bearing trees such as oaks, are likely to spread by more than a few hundred feet per year. Poor soils may also limit the rate at which tree species can spread north. Thus, the range over which a particular species is found may tend to be squeezed as southern areas become inhospitably hot. The net result is that some forests may tend to have a less diverse mix of tree species. Water Global warming also changes in rainfall, temperature, humidity and wind. They are all likely ?side effects? of global warming. are just a few of the elements that can effect the quality of water used for drinking, recreational and commercial purposes. In addition, seafood from contaminated water, or fresh produce irrigated with contaminated water, can carry disease. In Australia, in the summer, rainfall increases of up to 5% per degree of global warming are predicted in southeast Australia and of up to 10% per degree of global warming elsewhere. In the winter, three separate regions are identified: the models agree on an increase (of up to 5% per degree warming) in Tasmania, agree on a decrease (of up to 5%) in central and south Australia, or fail to agree (-5% to +5%) in eastern and southwest Australia. The average global warming falls in the range of 0.6 K to 1.7 K by 2030. For example, the maximum increase of summer precipitation on the northeast coast will then range from 6% (0.6×10) to 17% (1.7×10). So lack of drinking water is becoming a problem. Impacts on health Weather has a profound effect on human health and well being. As average temperatures slowly rising up in coming decades. The effects of a warmer climate may begin to take a toll. Particularly those who cannot afford air conditioning, or are already physically weaker (elderly) are going to have a harsh life. During the hot summer of 1995, the frightening effects of high temperatures were felt in Chicago, when 700 people died as a result of heat-related problems. Weather has a profound effect on human health and well-being. It has been demonstrated that weather is associated with changes in birth rates, and sperm counts, with outbreaks of pneumonia, influenza and bronchitis, and is related to other morbid dirty effects linked to pollen concentrations and high pollution levels. Global warming is also expected to result in more extreme weather events, just like heavy storms and floods. Beyond a rise in weather related injuries and fatalities powerful storms. The secondary health impacts of extreme weather, such as bacterial illnesses resulting from damaged public facilities like having lack of clean drinking water and psychological problems from the mental stress of experiencing a natural disaster. Health problems will vary dramatically around the world. Pest & disease ?climate change may benefit ecological
conditions for insect growth and abundance which is likely to have a negative
effect on crop, livestock and forest production in some areas. ? ipcc, 1992
Major health impacts are possible, especially in large
urban areas, owing to changes in availability of water and food and
increased health problems due to heat stress and spreading of infections. ? ipcc 1990

Moths, beetles and spiders might seem like innocuous household pests, but in a global warming world they have the potential to wreak havoc on crops, forests and human health. We are already seeing signs of pest population explosions: According to the World Health Organization (who) there are already 110 million cases of malaria and up to 2 million deaths from it worldwide each year. Increases in temperatures are creating ideal mosquito-breeding conditions in new regions, including the usa, Australia, UK, Bangladesh, China and Egypt and continue spreading all around the world. Our health is threatened by climate change. Malaria, asthma, encephalitis, tuberculosis, leprosy, dengue fever and measles are all expected to become more common through the world due to global warming. Air Air quality in many parts of the country is already considered unhealthy. With global warming adding to it, it?s only going to get worse and worse. No element of the natural world is more essential to life than air, and no environmental task more critical than keeping it cleans. Because electric power plants and motor vehicles are by far the biggest sources of air pollution, from lung damage to acid rain to global warming Air pollution and heat advisory warnings should specifically target children and the elderly. For example, as air gets hotter, it mixes with sunlight and produces ozone smog, which damages human lungs, as well as trees and vegetation. A related problem is an inevitable increase in air-conditioning use. Power plant emissions will also increase if additional controls are not established. Economic Global warming would reduce global food production, increase prices and cause new uncertainties about food supplies. That means the demand for food will be higher than the demand of supply of food in the future caused by global warming. Significant declines in grain yields are forecast for Africa, tropical Latin America and much of India and Southeast Asia. Reduced yields are also projected for the usa, Canada, the Middle East, and southern Europe. Global warming is big business. Some economists argue that a warmer climate could benefit certain crops and the farming communities. However, property insurers are predicting that worsening storms caused by global warming could eventually bankrupt the insurance industry. Insurance companies are now trying to form strategic alliances, and pool resources, which could cover severe economic loss from climatic changes. The potential costs of cutting greenhouse gas emissions might sacrifice economic growth or our standard of living in challenging of climate change. By doing this we might need to change in behavior and investments in technology In the short term, changes in economic activity that could impose costs on society. The costs of climate change reflect the magnitude of the emissions reduction, the timing of these reductions, and the means of implementation. Solution Government rule to protect the environment Today, action is occurring at every level to reduce, to avoid, and to better understand the risks brought by climate change and their harmful affects. Many cities and states around the world have prepared greenhouse gas inventories; and many are actively pursuing programs, education, advertisement and policies that will result in greenhouse gas emission reductions. Encouraging people in recycle program and planting trees There are countries like America introduced The Pew Center?s policy program produces timely, independent, non-partisan analyses of climate change policy alternatives both in the United States and internationally. The Center seeks to advance the climate change debate by educating key decision-makers about policy options and encouraging the domestic and international community to reduce emissions of greenhouse gases. To accomplish these objectives, the Pew Center publishes a number of analyses, including:
A series of reports, focusing on effective and equitable policy
alternatives both in the United States and abroad;
A series of policy briefs, covering topics such as the key
elements of a prospective U.S. climate change program and
designing a climate-friendly energy policy;
Working papers on topics such as linking U.S. and international
climate change strategies; and
Analyses of legislative and Administration proposals, such
as President Bush?s climate change plan.
