Polar warming 'caused by humans' http://apocadocs.com/s.pl?1225484224
In 2007, the UN's climate change body presented strong scientific evidence the rise in average global temperature is mostly due to human activities.
This contradicted ideas that it was not a result of natural processes such as an increase in the Sun's intensity.
At the time, there was not sufficient evidence to say this for sure about the Arctic and Antarctic. Now that gap in research has been plugged, according to scientists who carried out a detailed analysis of temperature variations at both poles.
Their study indicates that humans have indeed contributed to warming in both regions.
