The United Nation’s Intergovernmental Panel on Climate Change (IPCC), the American Meteorological Society, the American Geophysical Union, and the American Association for the Advancement of Science agree that “greenhouse gases accumulating in the earth’s atmosphere as a result of human activities, cause surface air temperatures and subsurface ocean temperatures to rise” (Behreandt, 2006, p.The melting of ice from high altitudes and glaciers alters unique landscapes, influences the onset and duration of the seasons and consequently impacts animal and plant life. There is concurrent impact on people’s lives and livelihoods (UCS, 2007).An effect of global warming is to “accelerate the decomposition of soil organic matter, thereby releasing carbon dioxide to the atmosphere” (Jenkinson, Adams & Wild, 1991, p.304), which further increases the process of warming. Carbon dioxide is believed to be responsible for 55 percent of the increase in radiative forces arising from man-made emissions of gases to the atmosphere. There is about twice as much carbon in the top metre of soil as in the atmosphere, from which significant quantities of greenhouse gas would be produced by the soil as a result of global warming.The integrated impact of rapid temperature rise and other stresses especially habitat destruction, causes changes in animals and plants. There is “reformulation of species communities, reflecting differential changes in species, and to numerous extirpations and possibly extinctions” (Root, Price, Hall et al, 2003, p. Thus, tremendous changes in the species of animal and plant life is believed to be taking place, with possible exterminations as well as the development of new species.Another significant impact of global warming is expected to be an increase in malaria and dengue all over the world. “Increases in rainfall, temperature and humidity will favor the spread of malaria-transmitting mosquitoes over a wider range and to higher altitudes”, according to the Human Development Report (HDR, 2007). The disease kills about one million people every year, especially in Africa; and with global warming, an additional 220 to 400 million people may become susceptible to the disease.continued global warming. There will be increased heat and drought, rising sea levels caused by further melting of ice, and tropical storms of greater intensity. These natural changes will
