The BBC says:
The rise in temperatures at Earth's poles has for the first time been attributed directly to human activities, according to a study.
The work, by an international team, is published in Nature Geoscience journal.
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.
Other than the fact that the BBC seems to have completely garbled the fourth paragraph, this is as to be expected, and it's amazing that so much time and effort is wasted on this kind of research, which has such a totally predictable outcome. Unfortunately for these scientists, it is not (yet) illegal for humans to have an impact on the planet, and it is obvious to anyone who cares to take a look, that humans have a huge impact on the planet in all sorts of ways, and not just in the limited area they have investigated. (But so do trees, for that matter.)
