CLIMATE CHANGE

                   Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions, or in the distribution of weather around the average conditions . Climate change is caused by factors such as biotic processes, variations in solar radiation received by Earth. Certain human activities have also been identified as significant causes of recent climate change, often referred to as global warming.

                                     The natural world seems to be deteriorating around us, and it seems to be our fault. We are uncertain about the extent of the deterioration, the means that would reverse it, and the prospects for human life in the future.
