Global warming refers to an unequivocal and continuing rise in the average temperature of Earth’s climate system.[2] Since 1971‚ 90% of the warming has occurred in the oceans.[3] Despite the oceans’ dominant role in energy storage‚ the term "global warming" is also used to refer to increases in average temperature of the air and sea at Earth’s surface.[4][5] Since the early 20th century‚ the global air and sea surface temperature has increased about 0.8 °C (1.4 °F)‚ with about two-thirds of the increase

Global Warming: The Causes‚ Effects and the Human Influence Global warming refers to the rise in temperature of the earth’s surface. There exists an intricate ecological balance within the earth’s atmosphere. Slight increase in the temperature of the earth’s surface creates a serious ecological imbalance with far reaching consequences on earth’s aspect of life. The activities that contribute to such a change on earth are much likely attributable to humans. Earth is being effected highly by green

Global Warming A common topic known worldwide as controversial and challenging is global warming. Many people do not know the cause and effect between man-made activities‚ practices‚ and behaviors that have contributed significantly to global warming. All nations should be required by law to curtail‚ modify‚ or stop such activity. A great difference in climate change will occur if people around the world became aware of their actions to achieve a more stable and safer environment. Scientists

Global warming There are already many natural disasters‚ for example earthquakes in Mexico or floods in Pakistan‚ probably the first effects caused by global warming. But that is just the beginning; the number of natural disasters will increase in the future. In my speech I tell you something about global warming and what we can do to prevent it. At first I define the term “global warming”: It is the change of the climate caused by the people for example the destruction of the ozone layer and the

Global warming Global warming the biggest threat in 21st century Introduction The term global warming has been common in the fields of whether and climate. The term does not posses the literal meaning as such but simply implies change in climate. The change in climate is attributed to overall rise in average temperatures of the universe. This poses a great threat to mankind (Korgen‚ 2007). The dangers attributed to global warming include health issues‚ scarcity of some vital natural resources

Thesis: Global warming is a human induced phenomenon causing a dramatic rise in average global temperatures and posing a major threat to our planet and it’s ecosystems. Points of Evidence: The science is clear: Human activity is causing our climate to change. -When we extract and burn fossil fuels such as coal or petroleum‚ we cause the release of carbon dioxide (CO2) and other heat-trapping “greenhouse gasses” into the atmosphere. Though natural amounts of CO2 have varied from 180 to 300

Global Warming is caused by human pollution; Nowadays our environment becomes different from the past‚ now the world is becoming dangerously warmer due to the human pollution of greenhouse gasses‚ such as carbon dioxide‚ methane‚ nitrous oxide‚ and deforestation‚ which it traps heat that would otherwise escape from Earth. “These are the Top 10 Global Warming Effects and Causes: (1) Carbon dioxide emissions from fossil fuel burning power plants; our over increasing addiction to electricity from coal

This phenomena has been given the title global warming‚ and has sparked a new debate in local‚ state‚ national‚ and world policy. Since the end of WWII the United States has played the role of international policeman. As one of the strongest economic‚ political‚ and economic powers in the world the United Nations Special committee on Global warming research has also made us the leading emissions releaser in the world‚ with approximately one fifth of all global emissions coming from our country.
