The world's forests provide many important benefits to the planet: more than half of all species on earth live in the world's forests. Global climate change and the world's forests are inevitably linked, the negative effect of global climate change on the world's forests affects human beings biologically and socio-economically. Global climate change is any significant change in climate measurements such as temperature, precipitation. , or the wind. The main indicators of climate change are the greenhouse effect, in which atmospheric gases such as carbon dioxide trap solar radiation in the atmosphere. (Climate Change Indicators 1-2) Projected by the EPA as one of the greatest environmental challenges facing the world today. Global climate change and the greenhouse effect are the result of human activity. If we don't slow down, the consequences will be disastrous for the world. In recent decades, evidence of human influence on climate change has become increasingly abundant and clear. There is compelling evidence that human activities such as the burning of hydrocarbons contribute to greenhouse gas concentrations and global climate change. An increase of 14 percent between 1990 and 2008. Carbon dioxide accounts for the majority of the country's emissions. Carbon dioxide emissions are not the only side effect of global climate change; they also affect Earth's temperature and weather conditions. Average temperatures have increased in the lower 48 states since 1901, with warming accelerating. Seven of the 10 hottest years on record in the Lower 48 states have occurred since 1990. Contrary to popular belief, global climate change is not the same thing as global warming, because in global climate change it there is also an increase... middle of paper......global climate change states: “Our generation inherited an incredibly beautiful world from our parents and they from their parents. It is in our hands whether our children and their children will inherit the same world. (Branson) The forest offers us a wide variety of resources. Millions of people benefit from the forest, but the future is bleak for the world if we don't have a vibrant forest. Works cited by Feeley Kenneth J. “effects of global change on tropical forests”.
