Global warming: fact or fiction?

The average global temperature of Earth has increased by 0.8 degrees Celsius since 1880 at a rate of 0.15-0.20 degrees Celsius per decade, which may not seem a lot but can have destructive impacts on the oceans. As shown on the diagram below, the area with the largest temperature change is at the poles. Consequently, the rate of the melting of the polar ice caps has increased. According to statistics from NASA the thickness of the ice at the arctic pole has decreased by 40% since 1960 and the ice is melting at a rate of 9% per decade.

However, there are some people who believe that global warming is a "myth". There are statistics that show an increase in the size of the polar ice caps over the past year since summer 2012.

As shown in figure 3 below the polar ice caps appear to have increased in size from August 2012 to

In this geographical issue I will be discussing the views of different sources and the scientific evidence that prove whether global warming is fact or fiction.

Fiction

This source believes that global warming is fiction. Although the volume of atmospheric CO2 is rising, 290 parts per million at the beginning of the 20th century which has increased to currently 360 parts per million, scientist have carefully monitored the atmospheric temperature over the past 50 years and have shown that greenhouse warming is not occurring and is unlikely to because the actual temperature...
