Global warming: a human impact Essay

According to Wikipedia the redundant encyclopedia, global warming was ascertained by Joseph Fourier in 1824 and investigated quantitatively by Svante Arrhenius in 1896 and is stated as the warming of planets step up due to emission of infr ard radiation by atmospheric gases. Thus global warming crapper be described as an increase in average temperature of the human beingss surface air and oceans in recent times and its predicted continuation. Intergovernmental gameboard on Climate Change (IPCC) predicted a rise in temperatures by 1. 1 to 6. 4 C i. e. , 2. 0 to 11. 5 F mingled with 1990 and 2100.The global average atmospheric temperatures near the earths surface rose from 0. 74 0. 18 C i. e. , 1. 3 0. 32 F in the last century. The general scientific opinion prevailing on the climatic change is that most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentratio ns. Certain human activities such as burning of fossil fuels, deforestation and agricultural activities result in complete of green house gases such as water vapor, carbon dioxide, methane, nitric oxide and ozone. lifelike phenomenon such as solar temperature variations and volcanoes too had an impact on global warming. This rise in global temperatures has serious implications such as rise in sea levels, changes in pattern of precipitation olibanum head uping to droughts, floods, heat waves, hurricanes, tornadoes and ice shelf disruption such as the Larsen Ice Shelf. Other implications could be variations in agricultural yields, glacier retreat, reduction in summer stream flows, extinction of species and increase in the range of infirmity vectors.Natural Resources plea Council (NRDC) stated that global warming could also lead to deadly heat waves and spread of disease. Extreme heat waves in 2003 caused to a greater extent than 20,000 deaths in Europe and over 1500 deaths in India. Dengue fever computer virus carrying mosquitoes survived previously at an altitude of 3,300 feet but recently they were found at 7,200 feet in Andes Mountains of Colombia, similarly malaria was detected at higher altitudes in Indonesia. Disease-carrying mosquitoes are spreading as climate shifts allow them to survive in in one case inhospitable areas.Mosquitoes that can carry dengue fever viruses were previously control to elevations of 3,300 feet but recently appeared at 7,200 feet in the Andes Mountains of Colombia. Malaria has been detected in virgin higher-elevation areas in Indonesia. Wikipedia the free encyclopedia stated that more than 160countries signed the Kyoto communications protocol an international agreement to combat global warming. The Kyoto protocol is an amendment to the United Nations material Convention on Climate Change (UNFCCC) and the countries ratifying this protocol are move to reduce emissions of carbon dioxide and five other green house gases. create countries such as China and India which rank second and third largest carbon dioxide behind the US are exempted from meeting the emission standards in this protocol. growth in CO2 leads to its dissolution in ocean water and forming carbonaceous acid resulting into ocean acidification meaning a change in pH of ocean waters and consequently a total change in the eco-balance leading to disappearance to certain species of living forms in the ocean.According to the Natural Resources Defense Council (NRDC), simple measures such as usage of renewable sources of cypher like sunlight, wind, wave energy and replacement of decade old blacken burning power plants with cleaner and efficient ones would curb the global contaminant and attend to in reducing carbon dioxide pollution positively. Concluding the paper I would like to state that sincere efforts are required to do by the governments in countries like the US, China, India and Japan to minimize pollution with the help of g overnmental and non-governmental organizations for a better life to future generations.Works Cited Wikipedia the free encyclopedia.
