Global warming is the rise in earth 's surface temperatures . This rise in temperatures is linked to the increased concentrations of green house gases brought about by human activities such as burning of fossil fuel together with cutting down trees . An increase in temperature will have an effect on the level of sea altering the quantity and pattern of rainfall . It may also lead to spread of deserts and changes in weather conditions

which will affect agricultural yield and also different species of animals which could be faced with danger of being extinct

Although global warming has been greatly blamed on human activities other scientists do not believe that it 's the case . They believe that global warming is not occurring and that the change in temperatures is a cycle . Satellite data indicates that there was a rise in the world 's temperature between 1680 and 1940 but it started cooling since that time until 1980 (Weart ,2003 . The situation reversed in the 1990s in which temperatures again started rising leading to the current global warming Controversy arises on the cause of these climatic changes in temperature although to some , they view it as a cycle that is being repeated with trends indicating a possible cooling in the global temperature (Allen Seaman Delascio , 2009
