1) What is global warming? (History) Definition: Global warming is the observed century-scale rise in the average temperature of Earth’s climate system. Common sense:Glaciers are melting‚ sea levels are rising‚ cloud forests are drying‚ and wildlife is scrambling to keep pace. It’s becoming clear that humans have caused most of the past century’s warming by releasing heat-trapping gases as we power our modern lives. Called greenhouse gases‚ their levels are higher now than

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

eThe phrase global warming refers to the documented historical warming of the Earth’s surface based upon worldwide temperature records that have been maintained by humans since the 1880s.It is the increase in the average temperature of the Earth’s near-surface air and oceans.In the last 100 years‚ this temperature increased by about 0.8 °C (1.4 °F) with about two thirds of the increase occurring over just the last three decades.According to the exponentss of the concept‚the likely effects of a further

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

Jacqueline Sanchez Brad Stiles Research Paper Global warming is no longer a myth and as consumers of resources‚ the world has to change and conserve their energy usage. There are many things one can do‚ but informing others how to take these dire steps our world needs in order to survive and support humankind. With CO2 making up over 70 percent of our atmosphere‚ we need to focus not only on how to slow down its growth‚ but removal of it s existence from the atmosphere to the right level of

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
