Global Warming speech to inform/persuade I. Introduction: A. "Global warming is the observed increase in the average temperature of the Earth’s near-surface air and oceans in recent decades and its projected continuation. B. The average global air temperature near Earth’s surface has risen about 0.74 °Celsius (1.3 °Fahrenheit) in the last century C. Models of global warming referenced by the Intergovernmental Panel on Climate Change (IPCC) predict that global temperatures are likely

GLOBAL WARMING AND CLIMATE CHANGE Uzochukwu Chekwube BSC2011 Professor Bloodworth July 21‚ 2014 Global warming is still a debate between us. Most people do not believe that our world is warming up‚ they believe the climate is in a cycle‚ and that humans do not contribute to the warming of our climate. Research supports the fact that Global warming is a huge factor in climate change and that

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

worrying problem that is seriously affecting our planet lately; this problem is known as Global Warming. Global warming as its name states is a global phenomenon with a number of effects that is happening in the global level. (D’Silva 2007). Global warming is poses a great threat to our personal lives and also to our world. More and more problems that are happening around us are mainly because of global warming. Our earth is not the same place anymore compared to decades ago‚ it is now slowly dying

Global warming is the increase in average temperature of the Earth’s atmosphere and oceans over time. Most of the warming observed over the last 50 years is attributable to human activities‚ especially the emission of greenhouse gases such as carbon dioxide gas. In recent years‚ extreme heat waves caused more than 20000 deaths in Europe. Also‚ melting icebergs and rising sea levels are observed. Global warming is a crucial problem in the world‚ it may lead to disastrous consequences such as extinction

------------------------------------------------- Global warming Global warming is the rise in the average temperature of Earth’s atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century‚ Earth’s mean 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 it is primarily caused by increasing

GLOBAL WARMING What Is Global Warming? Global warming is the warming of the earth through carbon dioxide (CO2) being pumped into the atmosphere from tailpipes and smokestacks. Then the gases trap heat like the glass in a greenhouse. This is where the term the “greenhouse effect” came from. What’s Happening Scientists say that the barrier insulating the continental ice caps is melting. “The impacts of warming temperatures in Antarctica

Global Warming Global warming is a huge environmental and economic challenge that we are facing in the 21st century. Global warming is also commonly referred to as the greenhouse effect. Global warming can affect entire ecosystems and climates‚ which in turn affect the way in which people live. We in our lifetimes will not be around to see the major outcome of global warming; however‚ it is still a major concern. It has come to be known that the major increase in temperature over the last century

GLOBAL WARMING We don’t agree on everything‚ but the world does seem to agree on one thing : Global warming is happening‚ and it’s causing big problems. Global warming refers to the increase in the temperature of the Earth’s atmosphere and it’s oceans. A change that is believed to be permanently changing the Earth’s climate. Scientists have spent decades figuring out what is causing global warming and what is its effects. Global warming is a major problem in the world that should everyone know
