Global warming first mentioned by ‘Svante August Arrhenius in 1896’, but in ‘1753, Joseph Black discovered carbon dioxide’ and in ‘1827, Jean-Batiste Fourier suggested that atmospheric effect kept the earth warmer than it would otherwise be’, (Direct.gov. n.d. A history of climate change). Since this time, reports, and study have be done with graphs to show the impact of global warming and what could happen to our planet. In 1979, the first conference was held this was called ‘International climate science’ it called on governments to ‘foresee and prevent man-made changes in climate’. 1988 the ‘IPCC’ was setup by the ‘United Nations’ to look at reports and the findings, they advised measures to stop ‘greenhouse gases to prevent global warming’. 1992 ‘154 nations signed the UNFCCC’ this was to set targets to ‘reduce emissions’ 1997 ‘Kyoto Protocol’ is an ‘international treaty and legally binding for industrialised nations to cut emissions 178 countries’ signed this treaty which was in ‘force in 2005’(ibid). There have been four different meeting each setting up different names, treaties after looking at the findings in each case, this is to make sure all countries are aware of global warming. The causes of global warming are the emission to the earth’s atmosphere of CO2, these come from ‘fossil fuel like coal: oil, gas, and deforestation’. The world uses these fossil fuel to ‘heat homes and building for growing, transporting and cooking food, travelling, treating water to make it drinkable, manufacturing, from clothes to fridges and plastic bags and batteries’ (Direct.gov. n.d. Causes of climate change). The ‘Ozone layer’, is another concern for scientists; the ‘depletion of the earth’s ozone layer’ means more ‘Ultra Violet Radi... ... middle of paper ... ...lobalwarminginperspective.wordpress.com/global-warming-myth-vs-reality/ [Accessed 10th Feb 2001] Glover, P. 2007.

Most climate scientists agree that the main cause of global climate change is the human expansion of the greenhouse effect. This is the global warming that results when the atmosphere traps heat radiating from Earth toward space (climate.nasa.gov). The main gases that contribute to the greenhouse effect include water vapor, carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons (climate.nasa.gov). Human activities are changing the natural greenhouse effect. The burning of fossil fuels like coal and oil has increased the amount of carbon dioxide in the atmosphere (climate.nasa.gov). Carbon dioxide levels have increased from 280 parts per million to 379 parts per million in the last 150 years due to human act...
Global warming is an increasing threat to the Earth and future generations. Global warming, sometimes called climate change, is the name given to the process of heat getting trapped in the atmosphere and damaging the environment. Greenhouse gases cause heat to gets stuck in the atmosphere by trapping the sun’s rays. When the sun’s rays enter the Earth, they should bounce back into the atmosphere. Instead the gases trap them, causing the temperature to rise. In the past the temperature of the Earth has risen slowly and evenly but recently the temperature has risen faster. The temperature of the Earth has risen at least one degree Fahrenheit during the twentieth century. If global warming is not controlled there are serious consequences. People, animals, and plants could be living in an atmosphere that is not suitable for sustaining healthy lives.
Global warming and global climate change is the study of future increases of temperature across the globe. Studying climate change refers to how the over- all climate will change such as the dry places getting dryer and the wet places getting wetter. Global climate is dependent on “the greenhouse effect a natural process that helps regulate temperature” (Easterling and Karl). In the past few centuries humans have had a monumental effect on increasing of greenhouse gases in the atmosphere. Climate change is result of the increase amount of the greenhouse gasses in the atmosphere such as methane, carbon dioxide, water vapor, nitrous oxide, and ozone. “Global temperature has rose approximately 1.4 degrees Fahrenheit over

Furthermore, this analysis must take place amidst serious gaps in the existing research and technology concerning the developing climatic conditions. For these reasons, global warming stands as one of the most daunting policy issues facing our world today. This is compounded by the debate over the very existence of climate change. While countless sources of empirical evidence testify to the very real presence of climate change the world over, considerable denial of the phenomenon still exists. The argument has been made that evidence of climate change is a gross overstatement, or in some cases, a complete fabrication.

The commonly debated “greenhouse effect” refers to “the global average temperature increase that has been observed over the last one hundred years or more” (Spencer). President Barack Obama addressed the issue in an effort to highlight its severity, "We have to all shoulder the responsibility for keeping the planet habitable, or we’re going to suffer the consequences – together” (Leader). The earth’s increasing atmospheric and oceanic temperatures result in climate changes due to cumulative amounts of carbon dioxide (CO2) in the atmosphere. As an outcome, researchers around the globe have established that the by-product of burning fossil fuels is the main culprit of the increasing temperatures. Global carbon emissions from fossil fuels have significantly increased since 1900, as shown above from a study carried out by the Carbon Dioxide Information Analysis Center.
In talking about global warming, we need to learn what causes the greenhouse effect. Rays from the sun are taken up and absorbed by water vapor that is natural in the atmosphere. The United States emits the largest man made greenhouse gases in the world. As Americans we must realize the responsibility to reduce the emissions. (Gore, Albert) Water Vapor is eighty percent of greenhouse warming. The last twenty percent results from other gases that are in very little amounts. A huge absorber of the sun’s heat rays is carbon dioxide. Us as humans release a lot of carbon dioxide. When fossil fuels are burned, they release big amounts of carbon dioxide. Carbon dioxide is on the increase in our atmosphere due to car emissions. Approximately eighty percent of CO2 increases because of man’s use of fossil fuels. When there is more carbon dioxide in our atmosphere the more sun rays are absorbed. In result to this happening this will cause the earth and the earths atmosphere to warm. When the earth is warming, water temperatures will start to get warmer. Oceans and lakes will get warmer in result f...

As we approach the future we are faced with many global problems. Most of these problems arise because we have caused them ourselves. We need to face these problems and find a solution. Global warming, although most often overlooked in importance, is a crucial problem of the future directly related to human activities. Global warming is caused by gases humans release into the atmosphere called anthropogenic gases and by deforestation. Anthropogenic gases include carbon dioxide, methane, chlorofluorocarbons (CFCs), hydrofl...
Global heating and cooling has occurred on a cycle for millennia, however in the past thirty years the increased use of energy and fuels by humans has drastically changed this natural occurrence (Juerg, 2007). The largest cause of this warming is the release of carbon dioxide from the burning of fossil fuels. Carbon dioxide levels are twenty-five percent higher than they were in 1957 (UCS, 2013). This seemingly insignificant change has caused a myriad of negative effects. The endangerment of species, rising sea levels, and increased natural disasters are just a few examples of change brought about by global warming (Juerg, 2007).
Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. This results in an increased evacuation of greenhouse gases. “Short-wave solar radiation sinks into the Earth's atmosphere and warms its surface while long-wave infrared radiation emitted by earth's surface is absorbed, and then re-emitted by trace gases.” (2)
