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 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

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

Global Warming The greenhouse effect‚ in environmental science‚ is a popular term for the effect that certain variable constituents of the Earth ’s lower atmosphere have on surface temperatures. It has been known since 1896 that Earth has been warmed by a blanket of gasses (This is called the "greenhouse effect."). The gases--water vapor (H2O)‚ carbon dioxide (CO2)‚ and methane (CH4)--keep ground temperatures at a global average of about 15 degrees C (60 degrees F). Without them the average

time to rise again to secure our future‚” said former Vice-President Al Gore. Al Gore made a speech about global warming and said how to keep it healthy. The earth can be kept healthy and exist longer without global warming. Global warming is becoming a popular topic around the world. “Global Warming and the Greenhouse Effect” discusses what global warming is. This is how global warming is caused. Energy travels from the sun to the earth to heat it. The earth then radiates energy back into
