What Is Global Warming ? Global Warming is the increase of Earth’s average surface temperature due to effect of greenhouse gases‚ such as carbon dioxide emissions from burning fossil fuels or from deforestation‚ which trap heat that would otherwise escape from Earth. Earth’s climate is mostly influenced by the first 6 miles or so of the atmosphere which contains most of the matter making up the atmosphere. This is really a very thin layer if you think about it.

He also found climatologically evidence (in particular glacial erosion patterns) that could only logically be explained if the continents were

The Evolution of Life This section provides information about the evolution of life on Earth. For reasons of simplicity some important events and life forms were selected for each geological time span. However this should not give the impression that the evolution of life on Earth is or was a sequential event. Many life forms that were not mentioned in this text were very successful and have evolved or in some cases maintained a very successful life strategy. Prokaryotes‚ for example are the most

Broad and flat‚ plains are well named. Some appear when glaciers and streams erode away elevated terrain; others spread where rising magma pushes‚ erupts‚ and spews. Some plains spill into the oceans‚ and others are bound by mountains on several sides. They all hide a tumultuous geologic history beneath their level disguise. The base of the vast Great Plains in North America formed when several small pieces of continental crust collided and welded together more than a billion years ago. As time

the similarities of coastlines such as those of east South America and West Africa; with the best fit being around1000 metres below sea level. Although they do not fit together perfectly‚ any irregularities can be explained. Gaps form due to the erosion of coastlines by the sea by abrasion and hydraulic action and areas where land overlaps are due either to volcanic activity creating new land when eruptions occur or changes in sea or land levels since the continents were separated.

In the Left Hand of Darkness‚ Ursula Le Guin describes setting in tremendous detail. The fictional planet that she so elaborately describes is known as Gethen or Winter. As indicated by the latter name for the planet‚ it is a very frigid and glacial planet. On this planet‚ the two major countries are Karhide and Orgoreyn. At one point in the novel‚ it is stated that there are some sixty-two words in the Karhidish language for the various kinds‚ states‚ ages‚ etc. of snowfall. It also states that

Global Warming is Happening Sometimes‚ it takes a huge blockbuster movie to affect a large population. On Memorial Day weekend in 2004‚ The Day After Tomorrow was released. The movie tells the story of a paleoclimatologist who warns the world of a possible abrupt climate change that could occur. While his warnings go unheeded‚ extreme weather becomes rampant throughout the world signifying an eventual end to humanity. The film stirred some controversy‚ however‚ since scientists claim that it

Scientific contemporary issues: The causes and effects of air pollutants There are many different air pollutants created from many different sources. Sources of air pollution range from car exhaust emissions (Carbon dioxide‚ Carbon monoxide‚ Nitrogen Dioxide‚ Lead & particulate matter)‚ industrial sources such as factories‚ power plants and refineries (Sulphur dioxide‚ Nitrogen dioxide‚ Carbon monoxide‚ carbon dioxide etc) air-conditioning and refrigeration (CFCs).

Some contributors were volcanic eruptions‚ melting of ice as well as sea erosion- all these made the Lake District as popular as it is now.

we must make it right’ (Al Gore‚ 2007) In the context of global warming‚ discuss the extent to which you agree with this statement. Global warming has been happening for millions of years through periods of glacial’s and interglacial’s. The last glacial period occurred during the last years of the Pleistocene‚ approximately 110‚000 to 12‚000 years ago and ever since then the earth has been warming up. However the change between the heating and cooling used to be for natural reasons but now scientist
