Climate Changing 'Faster, Stronger, Sooner"

Climate change is happening a lot faster than what was previously predicted, according to the WWF (world wildlife fund). They say the "most important aspect of data" is that in some places the arctic ocean is losing ice 30 years ahead of current ICPP predictions. Also, summer sea ice is now predicted to completely disappear sometime between 2013 and 2040 which hasn't happened in over a million years!
I personally think that it is most definitely is both natural occurrences and human behavioral issues. For example the ice age was a natural occurrence that took millions of years, but with the help of pollution the next serious change in climate is coming soon. Geoscientist Tina Tin said " Arctic sea ice is melting much faster than everybody had been expecting. Why? Well, maybe it's because the positive feedback mechanisms have kicked in much quicker than we have been able to quantify."(Tina Tin). Here's one thing that's triggering the ice to melt and quickly too. White ice sheets reflect heat from the sun. into space. This causes more dark sea water that also absorbs hear which therefore warms the Earth more. This encourages even MORE melting.
Not only does this cause melting of ice, it causes the Earths overall warming. For instance, the Mediterranean is likely to suffer an increased frequency of droughts. More data on this matter are due to be published next year by the Scientific Committee on Arctic Research next year.
