Increasing temperature of Earth has has put poles for the first time directly attributable to human activities, according to a study. The work, by an international team, is published in the journal Nature Geoscience. In 2007, the UN body on climate change presented strong evidence that the global average temperature increase is largely due to human activities. That contradicts the idea that this was a result of natural processes, such as an increase in intensity on sun.

At the time, there was sufficient evidence to say this for sure about the Arctic and Antarctic.
We really can not continue to pretend that it is natural that guides these variations to such big changes. Now this gap in research was connected, according to scientists who have made a detailed analysis of changes in temperature at both poles. The study indicates that humans have contributed to global warming in both regions. Researchers result was expected in the Arctic – a result of the recent sharp increase in melting of sea ice in summer in the region – but the  temperature changes in Antarctica have been so far difficult to interpret.

Today study, according to the researchers, suggests for the first time there is a discernable human influence on both the Arctic and Antarctica.
The research team took the temperature changes over Earth’s polar regions and compared with two sets of climate models.
A series assumes that there were no human influenza set the other was taken there. The best fit was with models that assumption that human activity including burning of fossil fuels and ozone depletion has played a role. According to one of the researchers involved in the study, Peter Stott, head of climate and monitoring for the award Met Office, formally showing that the Antarctic has been influenced by human activity was the main development:

In recent IPCC (Intergovernmental Panel on Climate Change) report, for example, he said, “unable to make a statement on the Antarctic, because this was not done a study at that time.
“But yet, when you do that you can clearly see a fingerprint found in humans. We really can not claim more than is natural that guides these variations are very big changes that we are seeing in our climate system.”
Professor Phil Jones, director of the Climate Research Unit of the University of East Anglia, said: “Our study is certainly close some loopholes in the latest report by the IPCC.
“But I still think a number of people, including some politicians are reluctant to accept the evidence or do nothing until they refused to say specifically that a particular event was caused by humans as a serious flood or somewhere even a heatwave.
“Until you go to small events in time and space, there will be people who still doubt the evidence.”
