(2) 13 October 2009 Global Warming The Earth's climate is constantly changing over time. Many climatologists believe that the temperature of the Earth slowly fluctuates over time. In fact, several scientists estimate that between 15,000 and 30,000 years ago the Earth was covered by large sheets of ice. This period of time was known as the Ice Age. As the temperature of the Earth began to rise 7,000 years ago, the Ice Age came to an end. The first theory of global warming came in 1824 when French

Global Warming Global warming has been one of the most fervently debated and scientifically challenging topics of the 21st century. According to NASA, as early as 1904, Swedish scientist, Svante Arrhenius, was among the “first persons acknowledged to investigate the effects of doubling atmospheric carbon dioxide and how this would affect the global climate”. (1) As technology and scientific studies progressed throughout the 1900’s and into the 21st century, the effect of human civilizations on

Global warming has affected many aspects of our society including one of the most important aspects which is climate change. Our Earth is warming. Earth's average temperature has risen by 1.4°F over the past century, and is projected to rise another 2 to 11.5°F over the next hundred years. Small changes in the average temperature of the planet can translate to large and potentially dangerous shifts in climate and weather.All these facts are proven in epa.gov. Do to these entire climate changes many

Global warming: The beginning of Armageddon My Artefact (1) / My Newspaper article (1) Scientists, celebrities, and everyday people have been trying to understand the nature of global warming. Controversy is rampant and there is intense debate around the world on the subject. The most obvious thing that can be said about global warming is that the earth is getting warmer. Specifically, the temperatures near the surface of the earth and the temperatures in the ocean are rising. Since 1990

Is Global Warming Skepticism Just Smoke and Mirrors? Dependence of Man on the Environment Greenhouse warming has always been a talk of the future and the talk of skeptics, well it is happening now. Representatives from countries all over the world will meet in July, 2011 to discuss slowing down global warming by setting the limits on the countries' greenhouse gases emissions, which include the emissions of carbon dioxide the industries, machines, and cars produced. (Reis, 2011). Despite of the

What is global warming? Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. This hurts many people, animals, and plants. Many cannot take the change, so they die. What is the greenhouse effect? The greenhouse effect is when the temperature rises because the sun’s heat and light is trapped

Global Warming: A Serious Problem for our World Trey Lee Northeastern State College Intro to Environmental Global Warming Global warming is a serious problem for our world. Global warming is an increase in the earth's average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. Global warming has occurred in the distant past as the result of natural influences, but the term is most often used to refer to the warming predicted

Global Warming Global warming is the greatest challenge facing our planet. It is, in fact, the increase in the temperature of the earth’s neon- surface air. It is one of the most current and widely discussed factors. It has far-reaching impact on biodiversity and climatic conditions of the planet. Several current trends clearly demonstrate that global warming is directly impacting on rising sea levels, the melting of ice caps and significant worldwide climate changes. But, what is causing the Global

Global warming refers to an unequivocal and continuing rise in the average temperature of Earth's climate system. Since 1971, 90% of the warming has occurred in the oceans. Despite the oceans' dominant role in energy storage, the term "global warming" is also used to refer to increases in average temperature of the air and sea at Earth's surface. Since the early 20th century, the global air and sea surface temperature has increased about 0.8 °C (1.4 °F), with about two-thirds of the increase occurring

Global Warning Lisa Ramos SCI 207 Dependence of Man on the Environment Instructor: Troy Breathwaite January 14, 2013 Gases such as carbon dioxide, methane and nitrous oxide are sometimes called Greenhouse gases, are increasing into our atmosphere causing climate changes. Scientists call this climate change – Global Warming. Sea levels are rising, glaciers are melting, and storms are raging fiercer than ever before such as Hurricane Katrina in 2005 and Hurricane Sandy in 2012. As the Earth
