Global Warming Global warming is defined as a gradual increase in the overall temperature of the earth 's atmosphere. (Google definition). The warming is generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants in the atmosphere. There is overwhelming evidence to support the existence of global warming, its cause and the time is how to act to reduce green houses gasses. Human activity is the major cause for global warming. Greenhouse gases (CO2) are directly caused by human consumption and burning of fossil fuels. When we extract and burn fossil fuels such as coal or petroleum, carbon dioxide (CO2) and other heat-trapping greenhouse gasses are released into…show more content…
It has long been recognized dating back to 1859. The greenhouse effect more commonly known as global warming has become one of the hottest contested issues of our time. Culminating in 2007 when former Vice President Al Gore advocated in a documentary “An Inconvenient Truth” that humans caused climate change is real and without immediate action to reduce greenhouse gasses, major climate changes will occur leading to a possible collapse of the industrial world. This documentary has been seen by over 5 million people worldwide and given Vice President Gore’s standing, his name has increased awareness of global warming. Proponents of global warming and former Vice President Gore advocate that the evidence of global warming and its effects are all around us. For instance, between 2003 and 2009 due to slight temperature increases, the Himalayan glaciers lost an estimated 174 gigatons of water. This melting contributed to catastrophic floods of the Indus, Ganges and Brahmaputra Rivers. Global warming has also contributed to the reduced size of the Arctic ice cap. As the Arctic ice cap shrinks it reflects less of the suns energy causing air and water temperatures to rise. According to the glacier monitoring service, since 1980 worldwide glaciers have lost nearly 40 feet. In addition to the melting glaciers, the bizarre weather patterns we are having demonstrate that radical changes in the atmosphere are occurring. Torrential rains in Colorado, flooding in
