Annie Lee POLS 1150 10 Global brief paper - redo 03/18/2013 Many people deny the fact that global warming is real; that a lot of it is caused by man. Man made global warming has become worse and worse throughout the years‚ and more research has proven that. It isn’t exactly 100% man-made global warming‚ but with a mix of manmade and natural global warming. Although it might seem like it is not such a big problem‚ manmade global warming has played more than 90% of the global warming’s problems currently

The biggest threat to life on earth comes from global warming. Rich industrialised countries in the West have been burning fossil fuel such as coal‚ oil and gas for about 150 years‚ pumping out vast quantities of carbon dioxide. This gas traps the heat from the sun and causes the Earth and the atmosphere to get warmer. This is called the greenhouse effect. So why global warming is a problem? Well‚ high level of these greenhouse gases in the atmophere causes climate changes‚ which also lead to

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

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 spins each day‚ the new heat swirls with it‚ picking up moisture over the oceans‚ rising here‚ settling

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‚ nitrous oxide is the third most climatologically significant greenhouse gas. Greenhouse gases act like a warming blanket in the troposphere and prevent radiative cooling. Nitrous

Environmental Threats Global Problems Sea Level Rising At present‚ sea levels around the world are rising. Current sea level rise potentially impacts human populations and the natural environment. Global average sea level rose at an average rate of around 1.7 ± 0.3 mm per year over 1950 to 2009 and at a satellite-measured average rate of about 3.3 ± 0.4 mm per year from 1993 to 2009‚[01] an increase on earlier estimates.[02] Climate change Destructive sudden heavy rains‚ intense tropical

Global Warming So does the earth need us or do we need the earth? Well we know that we need the Earth but how can we help what we need? Global Warming is killing our planet that is essential for our living. So many people have different views on Global Warming. Global Warming refers to an increase in the average temperature of the Earth as a result of the greenhouse effect‚ in which gases in the upper atmosphere trap solar radiation close to the planet ’s surface instead of allowing it to dissipate

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 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

We could all come together as one and leave all our differences of color‚ religion‚ and political views behind us‚ to stand together to face what Bill McKibben calls the greatest challenge and threat mankind has ever faced: global warming. In 2007 Bill McKibben‚ an author‚ educator‚ and environmentalist‚ wrote the article‚ “Global Warning: Get Up! Stand
