I decided to do some research on the issue in hopes of coming up with some type of conclusion based on the facts that I am able to find. The question always arises as to whether humans are to blame for our current global warming. Do humans in fact pose a threat to the global warming crisis and are they to blame for the slow increase in temperature of the earths atmosphere? Before one can begin to argue the facts whether or not humans have an

To begin with, there would be major changes in the average precipitation patterns. The tropics might possibly suffer from a lack of rain causing drought, while other regions may experience excessive flooding caused by rain and melting polar ice caps. Due to the melting ice caps, ocean waters would rise and large sums of land could be lost.
