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 su pposed 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 ââ¬Å"fiercer heat wave, harsher droughts, heavier rains and rising sea levelsâ⬠(1). The top three polluters of the world are China, America and India, in this order of magnitude. ââ¬Å"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.â⬠(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 il l effects of global warming, such as rising sea levels that can inundate low areas. Mitigation ââ¬â 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
