This quote from the BBC article sums it up.
The study highlights, however, the extreme complexity of the relationship between the biological processes of the Earth and the chemistry of our atmosphere - and how much there is yet to discover.
I stopped believing that the current warm spell is entirely man made some time ago. There are simply too many inconsistencies in the whole plot. But it's got like a religion now and it is sacrelige to doubt any part of the mantra.
One example: Apparently the melting ice cap will release fresh water into the sea near the arctic. This will divert the warming gulf stream to the south which will cause the weather here in the British isles to more closely resemble that of Canada. Meaning the winters will be long and cold with lots of snow. My problem with that theory is that if the snow is melting in the arctic and Canada is warming up. Then why would it snow more here?
The other problem I see is that people can't tell the difference between environmentally friendly and ecologically friendly. Recycling glass for example. Glass is sand. If you bury it in a hole in the ground. That's environmentally unfriendly but it does no harm other than being unsightly. So it's recycled which I like to point out is ecologically unfriendly. Any manufacturing or remanufacturing process uses energy and causes greenhouse gases to be released. It's the same with paper. Paper is made from trees commercially grown for that very purpose. Recycling paper cause more releases of greenhouse gases and reduces the number of forests planted to produce paper.
Recycling certain things makes sense, but others simply contribute to the problem.
Global warming is one of those myths we will all laugh about in the future.
