A team of MIT scientists recorded a nearly simultaneous world-wide increase in methane levels -the first increase in ten years. What baffles the team is that this data contradicts theories stating humans are the primary source of increase in greenhouse gas. It takes about one full year for gases generated in the highly industrial northern hemisphere to cycle through and reach the southern hemisphere. Since all worldwide levels rose simultaneously throughout the same year, however, it is probable that this may be part of a natural cycle - and not the direct result of man's contributions.

"Earlier we found torch-like structures like this but they were only tens of metres in diameter. This is the first time that we've found continuous, powerful and impressive seeping structures, more than 1,000 metres in diameter. It's amazing," Dr Semiletov said. "I was most impressed by the sheer scale and high density of the plumes. Over a relatively small area we found more than 100, but over a wider area there should be thousands of them."
So where in those links does it say humans caused it?
I suppose I could try to explain this in words of one syllable. However, the Arctic is experiancing the highest rise in temperature of any area on the planet. So that raises the temperatue of the ocean and land. And the permafrost and ocean clathrates are emitting CH4. A lot of CH4. Which, on a decadal time scale, is over 100 times as effective of a greenhouse gas as CO2.
You never answered my question. Where does it say humans caused it? Or are you hard of reading?
