Global warming is a rapidly increasing phenomenom. Many people choose not to believe that global warming exists, citing phrases like "Why is it snowing then?" and "It doesn't feel warmer" as arguments for how global warming is not occurring. Instead of entertaining these ideas, the more all-encompassing term used is climate change. Climate change references general changes in weather patterns, warming and cooling of large areas over long periods of time, increases in natural disasters, and the greenhouse effect's. Trends that have been proven scientifically and reserached by many highlight the patterns that are causing and increasing the effects of climate change. All levels of greenhouse gases are rising and temperature trends are increasing steadily by 0.2 degrees centigrade or more.
