Global Warming and Forest

The Western countries were the biggest polluters until a few decades ago. The developing countries must avoid the excesses indulgedby the west and learn appropriate lessons. Nature knows no political frontiers whether for climate change or transboundary pollution. The world has become warmer in the last 50 years mostly due to human activities. The global temperature may increase by between 1.4 to 5.8aC with such consequences as rising sea level and amount and pattern of precipitation. These may also manifest in extreme whether condition such as global retreat floods droughts heatwaves hurricanes cyclones and tsumaric. All these may lead to extinction of many specis and unintended consequences on human lives. Despite proliferation of knowledge of climate changes experts are divided on the linkages between human activities and the question of the changes. Most studies focus on the period upto 2100 through warming is likely to continue beyond then since carbon dioxide has a long atmospheric lifetime.
