Evidence:There is a lot of evidence pointing to the futures problems with global warming. First is the rise in temperature we have already had in the last ten years alone the average global temperature has risen more than one degree F. Based on estimates last year(2006) by NASA’s Goddard Institute for Space Studies‚ 2005 was the warmest year since reliable‚ widespread instrumental measurements became available in the late 1800s. About three-quarters of the anthropogenic (man-made) emissions of CO2

Global Warming In 1995 a popular science fiction movie called Water World‚ starring Kevin Costner came out. The plot of this movie is based on a distant future where the polar ice caps have melted‚ and the sea level has risen hundreds of meters covering all the continents and humanity is forced to live on abandoned ships and floating fortresses scavenging for supplies. Of course‚ this was only a science fiction movie‚ and in 1995 the idea of the polar ice caps melting was too far for society to

Global Warming: Origins‚ Effects‚ and Potential Solutions Since the dawn of the 19th century‚ civilization has been very dependent on the consumption of fossil fuels. Greenhouse gases‚ especially carbon dioxide‚ coming from these emissions plague our atmosphere. Greenhouse gases trap heat and prevent warmer air from escaping our atmosphere‚ which causes a containment of excess heat‚ thus causing a climate change; in this case‚ a rise in temperature. There has been large amounts of debate on whom

Two issues that worry many geologists are global warming and the greenhouse effect. The greenhouse effect is a natural process that keeps the earth at temperatures that are livable. What does the greenhouse effect have to do with global warming? When humans release gases into the air‚ the greenhouse effect will alter the temperature of the earth. More gases in the atmosphere means the earth will start to get warmer‚ and the result is global warming. On the other hand‚ if there was no greenhouse
Premium Greenhouse gas Earth Global warming
Global warming means a gradual increase in the Earth’s average lower atmosphere due to emissions and build up of greenhouse gases . Global warming is when the earth heats up and the temperature rises. It happens when greenhouse gases such as carbon dioxide‚ water vapor‚ nitrous oxide‚ and methane trap heat and light from the sun in the earth’s atmosphere‚ which increases the temperature. Greenhouse gases are released mostly by the burning of fossil fuels for transportation‚ heating‚ electrical

Global warming Global warming is the increase in the average measured temperature of the Earth ’s near-surface air and oceans since the mid-20th century‚ and its projected continuation. The average global air temperature near the Earth ’s surface increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the 100 years ending in 2005.[1] The Intergovernmental Panel on Climate Change (IPCC) concludes "most of the observed increase in globally averaged temperatures since the mid-twentieth century is very

Global warming Essay Global warming is simply defined as an increase in the average global temperatures. Though‚ it is an environmental problem‚ it has serious implications on the global economics‚ geopolitics‚ society‚ humanity and all living beings. “Global warming is one of the most controversial science issues of the 21st century‚ challenging the very structure of our global society” (Mark). Though‚ there has been controversies between two schools of scientific thought‚ one

Global warming and climate change threatens the very existence of mankind; understanding the affects of each and implementing measures to save this planet are of dire urgency. Global warming has become a threat to everything and everyone on Earth. Global warming is caused by many natural and manmade processes that continue to affect our environment. The release of carbon dioxide and methane gases are the two main contributors to climate change. With the warming of the environment almost inevitable

Global Warming One of the most challenging existing environmental problems is global warming. This refers to the change in climate that leads to an increase in the average atmosphere temperatures. Global warming is caused by a number of factors‚ but it is primarily associated with human action and more especially the excessive release of greenhouse gases into the atmosphere. An example of these human activities leading to increase in the amount of greenhouse gases in the atmosphere include burning

Global Warming Today‚ global warming poses the greatest threat to humanity and our planet earth. Global warming is actually not a new phenomenon by any means. In fact‚ it started alongside with the industrial revolution centuries ago. Nonetheless‚ global warming has taken an ugly turn due to rapid ongoing buildup of human-related greenhouse gases. For example‚ CO2 emissions reached 8.5 billion tons in 2008 and the average temperatures of the earth has risen by as mush as 0.2 degree Celsius
