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 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

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

Abstract Global warming is a direct result of human activities on this planet. Our species have inhabited this planet for thousands of years but only since the 1900’s have scientists been able to measure the changes that we have induced on earth. It is estimated that temperatures have risen globally by about 0.9 degrees Fahrenheit‚ which may seem minor‚ but have caused physical changes on the planet (and potentially dangerous ones in the future). The “greenhouse effect” is a term many politicians

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

challenges that global warming presents to both governments and business Introduction (250 word approx.) This essay discusses the challenges that global warming presents to both the government and also how they affect businesses. Many people think global warming is just the weather becoming warmer‚ but in fact this is not the case. Global warming makes the weather more unpredictable as some places become colder‚ some hotter‚ some more drier‚ some more wetter and so on. Global warming is defined as

Introduction A Global Warning: Global Warming | The world is warming dangerously. It depends either on the natural causes or the artificial causes like human based greenhouse gases. This affects both the vegetation and zoological environment and also the human | life. Its effects are gradually increasing every year.The purposes of our project are:·To investigate the causes and the effects of global warming and to present the results of our survey.·To attract attention on the solution proposals about
