  1. No, it hasn't been above 2C in quite some time. AMO haha
  2. http://data.ncof.co....MS/godiva2.html I have given the link several times now. http://www-das.uwyo....p17/arctic.html If you can find anything from the past that says anything different, show me. The anomaly is because the ice melted back to the Arctic basin allowing the gulf stream to flow in(the ice and meltwaters cause it to sink and underturn and go south) You see that back in early August I was expecting an inrush of Atlantic water into the arctic. This was because of the arctic storm and the melt back of the ice. Because I was expecting it, I was looking at the temperatures at depth in the arctic. It does not seem that anyone else has discovered this yet.
  3. Skier, the arctic deep has not changed 1C in the last 60 years. Until now. Now when things are changing rapidly +7C, you want to cling to past stability? Really? Well I guess you are just going to make up your own reality. Tis is the now reality.
  4. Yes those plumes are from deep in the sediment of shallower water. From 300m down they can form at the surface, in direct contact with the water. In shallower water, they require enough sediment to create the same pressure. At 300m methane hydrates have a melting point of 0C, while the water 2-3C that has reached the continental shelf is "cool" it is a destabilizing temperature. I showed the 2010 maps to show that the temps in the past were much more stable. this graph is not representing the arctic, the thermal gradient is wrong.
  5. The white area is the continental shelf at this depth. The shallower depths cant have hydrates except deep under sediments. There are no surface hydrates, so rapid destabilization is improbable, unless there is a landslide that uncovers them.
  6. Skier, Are you blind, while the warmest is in the middle, the warming reaches vast expanses of the continental shelves. Go back to the stability graph. 2C will destablize hydrates at this depth.
  7. It accumulates in the middle, then it spreads out. It has made significant advances in just 3 months. When will it get there? This winter, maybe. Next year when it gets another gush of Gulf Stream water, probably. But at this rate of advance we are not talking decades. edit; Significantly warmed 2-3C water has already reaches the continental shelves of Greenland, Siberia, the CA, and there is a patch on the Scandinavian CS. While the worst of it is still a ways off, the warming has already begun.
  8. http://scitechdaily....ound-in-arctic/ http://marine.usgs.g...ates/title.html There are significant methane hydrates in the 300-400m depths of the arctic, on the slopes of the continental shelves. edit; Every time I post you make up numbers and contradict me. Just how long did it take me to find references for the depths of the hydrates? About 30 seconds. Try using google and google scholar. Stop making up numbers to suit your purpose.
  9. I don't know if anyone else has factored in this huge influx of heat into the arctic basin. I have not read anything about it anywhere. I found it only because I was expecting it. In the past these depths did nothing year round, so I guess no one else bothers to look.
  10. The warmed area is between 400m to 0m depth so I don't know what you are talking about. New scale -2C - +2C This is the new mechanism for ice loss convection of warm water from depth. Here is thickness a year ago: This convection is torching a huge area and thinned it by 0.5m - 2m or more at N.E. Greenland. Its quit alarming 0.47m at 88.7N. It has lost at least 500 km3 on the Atlantic side through a combination of melting and failure to thicken.
  11. This is the Arctic ocean temperature at hydrate depth two years ago. Here is the same depth today(the scale is the same the data for today is kelvin two years ago, centigrade). In the arctic the hydrates should start just below the 300 meter level due to the 1-2C temperatures. The heat influx is getting down to the 400 meter level, where there are definitely hydrates.
  12. 6-8k years ago the oceans were still rising, and had been for 5k years(at a much faster rate). This gives little time for shallow hydrate formation, and the rising ocean stabilizes the deeper hydrates. edit: That is to say the top of the hydrate stability zone(where it is relatively easy to destabilize), would have hardly any hydrates to destabilize.
  13. Scientists Close in on the Cause of Arctic Methane Leaks http://www.climatecentral.org/news/scientists-close-in-on-the-cause-of-arctic-methane-leaks-15090/
  14. Yes, but its lifetime is concentration dependent, the more there is, the longer it lasts. Methane in the upper atmosphere protects the methane below. There is an online model available here. http://forecast.uchi...ts/methane.html Edit: graphs were not showing up
  15. This is today This is a year ago. You can see there was already activity a year ago. You have to like the trend.
