Revkin echoes my point from an earlier post" it’s important to get a handle on whether these are new releases, the first foretaste of some great outburst from thawing sea-bed stores of the gas, or simply a longstanding phenomenon newly observed.”
The Barrow readings of methane mean little. It's like taking the temperature reading of one city and claiming that represents global climate change. Of course if the Barrow readings went off the charts that would be something different. That's not happening.
