Methane spikes in the Arctic

The top two images show the latest methane levels recorded at Barrow, in the Arctic.

The bottom image shows the record slow refreeze of ice in one of the Arctic seas.

Is something happening in the Arctic?

The methane spike has not yet been picked up at other global sites, but if Barrow is showing the beginning of a feedback loop fed by melting undersea methane hydrates, and thawing permafrost, we may be seeing the beginnings of a climate change feedback loop and an increase in the rate of global warming.

With Arctic towns relocating because of melting permafrost, and seals and seabirds turning up dead in the high latitudes, things are looking a bit odd in the northern hemisphere.

And below, some food for thought. The graphic is by Reg Morrison.
