But today, there is no more doubt on this topic as the glaciers in the Arctic region of the world (located in the northernmost part of the Earth) are melting away fast due to the greenhouse gases caused by the burning of fossil fuels. Oil and coal are used to produce energy and electricity but they also produce by-products which are mainly carbon dioxide and methane that trap the sun heat energy. It is supposed to be reflected back to outer space in a process called as Albedo effect. A warmer Earth has changed the ocean's surface temperatures and also its salinity with serious effects on marine life (Ehrlich 1) and caused rising sea levels. This brief paper examines all its effects on the populations of low-lying areas of the world and what can be done about it. Discussion Even the skeptics are now convinced that global warming really exists as manifested by weather that has gone haywire, as mentioned in an article by Mr. Hertsgaard like a “fiercer heat wave, harsher droughts, heavier rains and rising sea levels” (1). The top three polluters of the world are China, America and India, in this order of magnitude. “The world pumped about 564 million more tons (512 million metric tons) of carbon into the air in 2010 than it did in 2009. That's an increase of 6 percent. That amount of extra pollution eclipses the individual emissions of all but three countries - China, the United States and India, world's top producers of greenhouse gases. It is a "monster" increase that is likely unheard of, said Gregg Marland, a professor of geology who has helped calculate Department of Energy figures in the past. This extra pollution in China and the U.S. account for more than half the increase in emissions last year.” (Borenstein 1). What is even more alarming is the observation that even if all emissions are stopped or discontinued today, global temperatures will still keep rising for 25 years. There are basically two ways or approaches by which people can deal with the global warming phenomenon: first is mitigation and the second is adaptation. Mitigation pertains to a front-end approach of reducing gas emissions to slow down the warming trend and it includes using renewable and clean energy sources, such as wind power or solar power. The other end of the equation is adaptation which are actions intended to safeguard a community or country from the ill effects of global warming, such as rising sea levels that can inundate low areas. Mitigation – everybody can contribute to reducing greenhouse gases by living simple lifestyles. The idea is to reduce a person's carbon footprint by using less fuel in daily living. It entails, for example, using the car less and walking more often, or using a bicycle for moving around. There are many ways by which one can accomplish this, such as reducing the use of manufactured products or consumer items that use a lot of energy, reducing use of electricity, or by patronizing more ...Download file to see next pagesRead More

Sea Levels and Melting Glaciers

...and floods in addition to melting ice caps and glaciers causing rising sea levels. These climate events were predicted by scientists’ years ago. Others admit the earth is warming but deny the source claiming naturally occurring global temperature cycles are to blame. By simply acknowledging the facts and ignoring political agendas, man’s impact on climate change becomes clear, unlike the air we breathe. Man-produced air pollutants, chiefly carbon dioxide, are commonly referred to as “greenhouse gases.” Carbon dioxide is emitted naturally by mammals when they breathe out and taken in by growing plant life. This cycle does not pollute the air, however, carbon dioxide emitted into the atmosphere from the...

Melting Pot

...? Due The American Melting Pot: Reality or Myth? Introduction When we look back on old documentary footage or watch period style movies we are often reminded of what the ports of the United States looked like at the turn of 20th century. People from all over the world came to this country with few belongings and a lot of big dreams of the better lives that they would build in this new land. They came to be free of the oppressions of their past and embrace the ideals and the freedoms of America. Ideally, these immigrants would bring the best of themselves, blend those talents, gifts and skills, and become Americans, sharing the unified hopes and greater goals of this country. The idea of the United States as an immense...

Melting Pot or Mess

...Your Your Melting Pot or Mess Why the United s Needs no Official Language In the years since September 11,2001, what had already been a predominant sentiment against immigration received the validation of fear: these foreigners seething into our country's borders might not only be taking jobs away from hard-working Americans, so the argument went, they might also be planning to murder thousands of those Americans. Forget the debate about illegal immigrants sucking up billions of dollars in health benefits, education for their children (who as often as not drop out before graduation!), and other social services - now the anti-immigration forces have the banner of national security to carry. To some, it may seem...

Oil Drilling and Arctic National Wildlife Refuge

...Oil Drilling and Arctic National Wildlife Refuge Submitted By: Submitted] Introduction During the first half of the year 2000, people in the United States were shocked when gasoline prices shot up nearly 100% in only a few months. The shock of the price increase caught the attention of a society that had grown dependent on private automobiles and gasoline, especially since the increase followed several years of a glut of inexpensive oil and gasoline. The reasons for the sharp price increase are complex but are based on several factors. First, as demand rose in response to low fuel oil prices, oil-producing countries reduced production rates, thereby reducing the supply. Second, in order to reduce air...

Postcolonial Melting Pot

...Running Head: POSTCOLONIAL MELTING POT Postcolonial Melting Pot [The [The of the Postcolonial Melting Pot In The Buddha of Suburbia, the space of performance, shifting from one margin to another, repeatedly destabilises the controlling narratives that define ideas of centre. Unsurprisingly, most commentators have tended to see Kureishi's sympathies as lying with the underdog. But such is the indeterminate subjectivity of both films-the contradictoriness of their characters, their unresolved ethical dilemmas, their wryly tragicomic representation of conflicted histories and divided allegiances-that they end up striking an ironic attitude to their own radicalism. Kureishi's approach...

Melting ice glaciers due to global warming

...in carbon content in the air has increased the global temperature which has caused glaciers to melt (Kayne). The resulting increase in the sea level is the main cause of hurricanes and cyclones which have endangered life on Earth. The enormous increase of temperature can greatly affect many ecosystems. Most importantly, ice is melting away. The following figure depicts fluctuations in the sea level along with the temperature variations over the last 450,000 years: Sea level vs temperature (Deem). Another study showed the exact relationship between increase in the levels of carbon dioxide and the sea levels ranged over a period of 520000 years: Sea levels vs CO2 content in the air...

Arctic Exploration and the Future of the Arctic Ocean

..., Russia, and Denmark have interest in the riches and the potentials of the Arctic Ocean. Some of these nations have parts of the Arctic Ocean as their territory because the area has vast oil deposits and lucrative business activities like trade routes. These opportunities have made the nations to vie for arctic dominance thus causing disputes between these countries (Shah, 2010). Using compass for direction in the arctic can be useless because of magnetic inclination. This is the difference between the geographic north and magnetic north poles. The North Pole is all one side of a magnet so when you have a compass, it will be repelled and attracted at the same time. The compass will end up pointing towards a random position... .

Arctic Plankton Bloom

...Arctic Plankton Bloom: Biological Productivity Arctic Plankton Bloom: Biological productivity Biological productivity or aquatic production is central to all biological processes in an inland aquatic ecosystem. It involves two main processes including primary production and secondary production. Primary production is the process by which living organisms form biomass from energy-poor inorganic materials in the environment with the help of photosynthesis. Under secondary production, the energy-rich organic material or biomass is transformed into other forms through consumption. According to the National Geographic, “biological productivity is defined as the ability of a water body to support life, such as...
