Arctic begins to refreeze - a month late!!! Arctic Methane Bomb confirmed to be "stirring"

Does anyone care except a few "global warming" geeks?

 


 So what ice remained at the minimum in September was very thin ice - as someone showed - the Northern Pole was cracked up ice.

So around a foot thick ice at most? Maybe a foot and half in some spots?

'Sleeping giant' Arctic methane deposits starting to release, scientists find

 


 How come I had to search this out on a geek arctic ice sea forum? It was NOT global news headlines?
 

The international team onboard the Russian research ship R/V Akademik Keldysh said most of the bubbles were currently dissolving in the water but methane levels at the surface were four to eight times what would normally be expected and this was venting into the atmosphere.

“At this moment, there is unlikely to be any major impact on global warming, but the point is that this process has now been triggered. This East Siberian slope methane hydrate system has been perturbed and the process will be ongoing,” said the Swedish scientist Örjan Gustafsson, of Stockholm University, in a satellite call from the vessel

 The 60-member team on the Akademik Keldysh believe they are the first to observationally confirm the methane release is already under way across a wide area of the slope about 600km offshore.

The latest discovery potentially marks the third source of methane emissions from the region. Semiletov, who has been studying this area for two decades, has previously reported the gas is being released from the shelf of the Arctic – the biggest of any sea.

For the second year in a row, his team have found crater-like pockmarks in the shallower parts of the Laptev Sea and East Siberian Sea that are discharging bubble jets of methane, which is reaching the sea surface at levels tens to hundreds of times higher than normal. This is similar to the craters and sinkholes reported from inland Siberian tundra earlier this autumn.
