This temperature increase may not appear noticeable or extensive; however, when considering detrimental worldwide effects there are many clearly correlated drawbacks to uninhibited climate increase. Each one degree increase in temperature leads to about a five percent decrease in grain yields. Maize, wheat, and a variety of other key crops are negatively affected with global yields decreasing forty megatons each year between 1981 and 2002 due to the temperature increase. Ocean temperatures increase, snow and ice has melted, and sea levels are rising, with sea levels increasing nineteen centimeters in the twentieth century and about one million square kilometers of ice lost every decade (The Science). The prediction made by the Intergovernmental Panel on Climate Change calculates that by the end of the twenty first century the global temperature will have increased to 1.5 degrees Celsius compared to 1900 levels. As stated by Professor Otmar Edenhofer, Director of the Mercator Research Institute on Global Commons and Climate Change, “Climate change is a global commons problem, International cooperation is key for achieving mitigation goals.
