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

molecule of carbon dioxide absorbs heat energy‚ it goes into an excited unstable state. It can become stable again by releasing the energy it absorbed. Some of the released energy will go back to the earth and some will go out into space. So in effect‚ carbon dioxide lets the light energy in‚ but doesn’t let all of the heat energy out‚ similar to a greenhouse. Nitrous oxide is known to have a significant global climatologic impact as a naturally occurring greenhouse gas. After carbon dioxide and methane

Global Warming The U.S. Environmental Protection Agency definition of global warming: “Global warming is an average increase in the temperature of the atmosphere near the Earth’s surface and in the troposphere‚ which can contribute to changes in global climate patterns. Global warming can occur from a variety of causes‚ both natural and human induced. In common usage‚ “global warming” often refers to the warming that can occur as a result of increased emissions of greenhouse gases from human

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 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

challenges earth is facing is Global Warming. The global warming hypothesis orginated in 1896 when Svante Arrhenius‚ a Swedish chemist‚ developed the theory that carbon dioxide emissions from the burning of fossil fuels would cause global temperatures to rise by trapping excess heat in the earth’s atmosphere. The term “Global Warming” signifies the temperature of the earth’s neon- surface air. The change in climatic conditions is one of the impacts of global warming. It is directly impacting on rising

GLOBAL WARMING AND THE EFFECTS ON EARTH One of the hottest topics being discussed now a days is the effects of global warming on the environment and the efforts being made in order to combat the potential effects. Simply put‚ global warming refers to the environmental effects caused by the constant emission of carbon dioxide from carbon based fuels. These effects are supposedly widespread; the temperature of the earth will rise‚ the land becomes less conducive to‚ vegetation‚ and various

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-Killing Earth’s Age Global Warming is defined as the increase in the average temperature of Earth’s Atmosphere. Since 1970‚ most of the increase has been in the oceans‚ which is about 90%. Global Warming also refers to the increase in temperature of the Earth’s surface. Since the year 2000‚ the surface temperature has increased about 0.8 0 C‚ which is about two third of the increase‚ when compared to 1980. Earth is getting warmer and warmer when days pass by. The main cause for
