Economics of Global Warming

Economics of Global warming Global warming has been on the rise for several years now, becoming one of the most modern issues in society. It is pretty evident that it cannot be ignored. Global warming is when the earth heats up resulting in a temperature rise; it happens when greenhouse gases are emitted into the atmosphere and causes trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. Resulting in several social and political effects like higher sea levels, agriculture, water resources and natural disasters.

As well as human health, animal and plants. Within the last century the average temperature has climbed about 0. 6 degrees Celsius which is about 1 degree Fahrenheit, around the world ( Lover, 2004). Most scientists believe the rises in temperature will intact increase dramatically and rapidly, as suggest it is not a natural occurrence. The United Nations- sponsored Intergovernmental Panel on Climate change reported in 2001 that the average temperature Is going to Increase between 1. And 5. 8 degrees Celsius ( 2. 5 and 10. 4 degrees Fahrenheit) by the year 2100. Lover,2004) One of the many social effects that global warming is causing higher sea levels as a result, scientists say could eventually submerge island nations, flood cities and expose millions of coastal residents to destructive storm surges( Roach, 2006). The loss of large areas of ice on the surface could accelerate global warming and because less of the sun’s energy would be reflected away from Earth t. Exulting In melting glaciers and a rise in sea level (Strickland, Granulations, 2005) melting of Ice glaciers are causing serious treats to Greenland and Antarctica. The rise in sea levels could cause flooding problems for low- lying coastal areas, but if Antarctica ice sheet were to melt of collapse into the sea, it would raise sea levels up to metes which is more than 32 feet; as a result man coastal area would disappear beneath the ocean ( Strickland, Groundbreaking, 2005). As well as reduced rainfall, droughts, and vanishing glacier will severely reduce the availability of drinking water. Vast,2005) Another factor leading to a rise In sea levels and melting of glaciers know as global warming, Is caused by the greenhouse effect. The greenhouse effects are known as one of the leading factors of global warming. The greenhouse effect, known as life on earth depends on energy from the sun and well we couldn’t live without it. 30 percent of the sunlight that comes toward Earth is deflected by the outer atmosphere and is put back into space. The rest reaches the planet’s surface and is reflected upward again as a type of slow- moving energy called Infrared radiation.

The heat caused by infrared radiation Is absorbed by “greenhouse gases” such as water vapor, carbon dioxide, ozone and methane, which slows its escape from the atmosphere (West,2009) It’s also well established that carbon dioxide in the Earth’s atmosphere has increased about 30 percent , enhancing the atmosphere’s ability to trap heat. ( Lover,2004) Most scientists believe that humans, by burning fossil fuels such as coal and petroleum, are largely to blame for the increase In carbon dioxide.

But some scientists also sate those natural causes like that increasing levels of uncontrolled industrial emission would eventually play havoc with the atmospheric conditions. Causing a huge impact on agriculture (Wheeler, 008). Because due to the Ice caps that will melt, causing flooding low-lying areas. As a result, crops will shrivel and food supplies will decrease ( Wheeler, 2008) The U. S food systems contributes about 20 percent of nation’s carbon dioxide emission, therefore agricultural land contributes 12 percent of global greenhouse gas emissions( Dunn,2009).

Manufactures and use of pesticides and fertilizers, fuel and oil for tractors, equipment, trucking and shipping, electricity for lighting, cooling and heating, and emissions of carbon dioxide, methane, nitrous oxide and other green souse gases increases the impact up to between 25 and 30 percent of the U. G’s collective carbon footprint. Deforestation, or paving over green space for suburban expansion, result in more surface warming( Dunn,2009). While chopping down a forest might make it “feel” cooler, forests have much greater potential to sequester carbon dioxide than does monoculture, industrial agriculture.

Farmers grow corn in climatic zones that are ideally suited to corn. It followed that any change in weather conditions, to warmer or colder temperatures would have a negative impact on the Ron crop, since it was a removed from ideal conditions. But new impact models used in his study assume that gradual warming will result in adaptive farming behaviors such as new tillage techniques, planting crops earlier, the introduction of more heat- tolerant species, and the northern migration of some crops. Under this scenario, global warming will benefit Canada, the United States, and Europe.

The CO effect will outweigh any losses in the agricultural sector. Conceivably, the limits of Canada’s rich agricultural prairies could be pushed further north (Wheeler, 1998). Tropical Mounties will probably not fare as well. Increased temperatures could push tropical crops out of their ideal growing ranges. But there may be counterbalancing effects. (Wheeler, 1998) There might be some initial overall benefit to warming for a decade or two but because future warming depends on greenhouse gas emissions today, if we delay action it would put global agriculture on an unstoppable trajectory to serious damage. Cline,2007) It is also possible that global warming will lead to global food shortages, Studies predicts that rice production will increase slightly in some Mounties, but that a substantial drop in output of wheat and corn is likely in major production sites such as China and India. It is estimated, for example, that the production of winter wheat will decrease by 55% in India and 15% in China by the year 2100. This will in turn have serious impact on Japan, which depends heavily on other countries for its food supply. (Fox, 2009) Global warming is also a contributing factor that will have impact on human health.

Humans health will be the ones who suffer the most from global warming. First off he rise in temperature will increase the chance of over working the cardiovascular system. Meaning that hotter temperatures will lead to an increase of heart and respiratory problems, and people who already do have heart problems are most vulnerable as it puts additional strain to the cardiovascular system to keep the body cool. ( Miller ,2007). Also a rise in allergies and asthma will potentially occur because of the Ozone layer. You see, higher air temperature increases ozone at ground level.

When ozone is mixed with dust, smoke and chemical fumes over urban, you’ll get OMG. Known as fog. It damages lung tissues and affect those with lung diseases such as asthma. (Shapely,2007). The rise in temperatures means rising heat related death. Headwater, a period of high temperature for more than 3 days and temperatures over 32 degrees Celsius, will be more frequent and intense. The European heat wave of 2003 was already bad enough. It led to a health crises in several countries that saw 35,000 people dead as a result of the heat wave (Roach, 2006) .

The rise in climate temperature also has a higher impact on natural habitats ND agriculture making them very vulnerable due to heat waves. Most importantly, the rise and spread of disease. Global warming might allow insects to carry infectious diseases like mosquitoes, ticks and sniffle. Cases of malaria, dengue fever, lame disease are Just some of the disease that may increase to a significant level in countries that had no reason to previously be concern with. ( Clark,2006). An increase of malaria disease in the highland areas of Papua New Guiana, where it has always been too cold for disease spreading mosquitoes. ASPI, 2008) Climate change may have an effect on human being but also animals and plants. A new study suggests that global warming could threaten one-fourth of the world’s plant and vertebrate animal species with extinction by 2050. ( Handwork,2006). This is also a huge effect of global warming because animals are essential to maintain the circle of life and the food chain. It is Just not the animals alone, insects, reptiles and the aquatic life are all interdependent on each other, and on the plants and humans as well. (Loveland,2009). Global warming causes climate change, deserts like the

Sahara, are no longer able to sustain their animal population. Loss of habitat is most seen in the Arctic, like previously mentioned because global warming is also melting the glaciers causing polar bears into extinction. Also due to rise in ocean levels many tropical island and forests and the animal life are threatened. Changes in weather patterns and coastlines affect the food patterns of most aquatic creatures. (Loveland, 2009) There is a general worldwide consensus there is climate change occurring, but many still claim it’s not man made, but a natural earth cycle.

While this may contain some Ruth, most believe it is caused from the burning of fossil fuels and man in general. The bottom line it is coming (if not already here) and we have to figure out what we can do. Waters rising will be a disaster, food will be affected and we go to plan for catastrophes like Strain. It’s social effects will impact out water resources, agriculture, human health and animals and plants will be harmed. This is going to hit everyone, not Just the poor or the democrats or the Catholics, we’re all in a heap of trouble and the sooner we accept this FACT, the better we can weather and try to fix r prolong the situation.
