GLOBAL WARMING : WHAT LIES AHEAD GLOBAL WARMING Climate change is a change in the statistical distribution of weather over periods of time that range from decades to millions of years. In recent usage‚ especially in the context of environment policy‚ it is more generally known as "global warming"‚ which occurs due to increasing levels of greenhouse gases in the atmosphere. Most of the observed temperature increase has been caused by increasing concentrations of greenhouse gases‚ which result

Global Warming The warming of the earth is one the biggest problems facing our nation and world today‚ and regardless of whether we agree or not on the causes of global warming there is an overwhelming consensus that the planet is warming. The causes of global warming are frequently debated between politicians and pundits on the news‚ however the overall scientific community have come to an agreement regarding those causes as well as the inherit dangers of global warming for life on Earth. To

Global warming refers to the rising average temperature of Earth’s atmosphere and oceans‚ which started to increase in the late 19th century and is projected to keep going up. Since the early 20th century‚ Earth’s average surface temperature has increased by about 0.8 °C (1.4 °F)‚ with about two thirds of the increase occurring since 1980.[2] Warming of the climate system is unequivocal‚ and scientists are more than 90% certain that most of it is caused by increasing concentrations of greenhouse

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

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. There

Abstract This report studies secondary research to discover the effects of global warming and the consequences it has on sea levels‚ ice melting and the polar bear. Websites researched were NASA‚ ICUN‚ National Geographic‚ BBC News‚ The Independent‚ IPCC‚ Arctic Council‚ National Resources Defense Council‚ UN News and D.V.D. called ‘An Inconvenient‚’ truth. Evidence researched supports the conclusion that scientists believe global temperatures have been rising and that human activity is a significant

CAUSES OF GLOBAL WARMING: Global warming also causes sea surface temperatures to rise‚ precipitation patterns to change‚ etc.. (NASA‚ 2002) Global warming can have many different causes‚ but it is most commonly associated with human interference‚ specifically the release of excessive amounts of greenhouse gases. (EPA‚ 2006) Global warming is caused by excessive quantities of greenhouse gases emitted into Earth’s near-surface atmosphere. Greenhouse gases are both man-made and occur naturally
