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 Global warming is an important issue in our society that a lot of people should be interested in as it will affect our lives for the rest of our life. How many of you already feel very warm in this room/hall? What if I tell you that in another 40 years‚ the temperature outside will be so hot it will feel like a baking bun inside an oven. This will be the exact situation that we’ll be in if we don’t stop it. Global warming literally means that the Earth’s average temperature is

October 3‚ 2013 Period 8 Senior Science Global Warming Controversy Humans have known about global warming for many years now. But Al Gore did not discover global warming. Neither did Tim Flannery‚ Peter Garrett‚ Greenpeace or Malcolm Turnbull. However they did add their scientific two cents and made everyone more knowledgeable on what this topic is really about‚ and stressed the importance it has on the Earth. Scientific concern about global warming is not new. This is nothing surprising or

Global warming is caused primarily by carbon dioxide from burning coal‚ oil and gas. Certain gases that trap heat are building up in Earth’s atmosphere. The primary culprit is carbon dioxide‚ released from burning coal‚ oil and natural gas in power plants‚ cars‚ factories‚ etc. (and to a lesser extent when forests are cleared). The second is methane‚ released from rice paddies‚ both ends of cows‚ rotting garbage in landfills‚ mining operations‚ and gas pipelines. Third are chlorofluorocarbons (CFCs)

issue of global warming has become an increasingly important issue. Global warming has been an issue that has been heatedly debated for many years. Scientists all over the world have been debating weather global warming actually exists. If it exists some scientists believe it is natural. While others believe it is caused by humans. Global warming is defined as an average increase in temperature in the atmosphere near the earths surface and in the troposphere. Which can contribute to changes in global

Climate Change Crisis Decades have passed since the first word of global warming came out‚ however‚ the problem has still has not found a solution. Not only is there no foreseeable fix in the future‚ but the earth will continue to warm leading to a plethora of extreme natural events occurring now and into the future. Scientists‚ geologists‚ and even politicians have invested millions of dollars into research and funding for campaigns on global warming. They all believe they have found a soltution

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.

Global Warming A common topic known worldwide as controversial and challenging is global warming. Many people do not know the cause and effect between man-made activities‚ practices‚ and behaviors that have contributed significantly to global warming. All nations should be required by law to curtail‚ modify‚ or stop such activity. A great difference in climate change will occur if people around the world became aware of their actions to achieve a more stable and safer environment. Scientists
