  1. Open inquiry: Is Antarctic extent’s apparent stall the result of El Niño conditions or wind gyres?

  2. I would think El Niño…Antarctica has lots of exposure to the Pacific

    • I was thinking that El Niño would be the more likely answer as well, but the stall has been around for only about 40 days or so (judging from the above graph, compared to 2014). El Niño conditions have been building since last summer, according to the Japan Meteorological Agency (JMA). Southern Atlantic and Indian Ocean SST’s out to about 45°S are for the most part unremarkable, so how much effect would El Niño have especially since the global thermohaline currents isn’t drawing tropical heat towards Antarctica at any reasonable rate?

    It appears that this year’s melt in extent is expected to end probably in 4th place with higher extents than 2012, 2011, and 2007…It might beat out 2008 as well….What warmists will tell you is that the rebound years of 2013/2014 was just a blip on a long steady downward trend line…I have a different response to this year’s melt season to me it was remarkably unimpressive…Let me state this again UNIMPRESSIVE… Why? We are at the 4th lowest extent are we? It all has to do with our starting point as we had the lowest starting point ever to the melt season this year so comparatively the amount of ice that melted in 2012 is significantly more than this year for that reason alone. If we had just an average melt year considering where we started from we should of smashed 2012.
