Global warming has both positive and negative effects to human beings and ecosystem as a whole. According to BÃ ¶hringer et al, several studies, shows that the global temperature shows a warming trend. Consequently, based on scientific studies of ice cores, coral reefs and tree rings; a result about the global temperatures increasing is made. Furthermore, starting from the Industrial Revolution in the mid of 1700s, the global average temperatures has increased with emphasize in the past several decades. According to World Meteorological Organization, temperature of global land surface has been ranked warmest from records calculated since 1880. Furthermore, global average temperature has increased over the last century by more than 1Â °F (0.7Â °C). Consequently, the 2001-2010 decade is the warmest since 1880. Actually, nine of the warmest recorded years happened in just the last 10 years. Moreover, this warming has come with a decrease in very cold days and nights and an increase in real hot days and warm nights.
