WUWT Regular “Just The Facts”
As you can see from the Southern Hemisphere Sea Ice Extent With Anomaly map above, there are currently two large fingers of anomalous Sea Ice protruding out in the Weddell Sea. This is the same Weddell Sea that in 2012 it was claimed that;
“Warm ocean currents are projected to melt the Filchner-Ronne Ice Shelf in the Weddell Sea area of Antarctica opening instabilities in the West Antarctic Ice sheet (WAIS) which will impact global sea level rise. Climate change is waking up the sleeping giant of Antarctica.
Significant scientific research has been published in recent weeks on the impact of global warming on changing wind patterns and southern ocean currents and the flow-on impact on Antarctic ice shelves and glaciers. The most recent studies reveal the potential instability of the Filchner-Ronne Ice Shelf in the Weddell Sea area. But the real questions to be asked concern the long term stability of the West Antarctic Ice Sheet (WAIS) and how rapidly it could collapse raising global sea levels by up to 6 metres.” Climate Citizen
So there are no apparent signs of the “warm ocean currents” that “are projected to melt the Filchner-Ronne Ice Shelf in the Weddell Sea area of Antarctica opening instabilities in the West Antarctic Ice sheet”. If fact those fingers still look reasonably concentrated;
and Antarctic Sea Ice Extent – 15% or Greater has remained above two Standard Deviations of the 1981 – 2010 average for the entire melt season:
Additionally, Southern Hemisphere Sea Ice Area Anomaly has been above the 1979 – 2008 Average for the last two years:
Southern Hemisphere Sea Ice Area Anomaly is in the midst of its third large spike since 2007;
and there is a clear trend towards larger Southern Sea Ice Area Minimums:
The result is Global Sea Ice Area had its highest maximum since 2006 and remained stubbornly average for the entirety of 2013:
However, in terms of the large fingers of Sea Ice protruding into the Weddell Sea;
I think they may be a sign from Antarctica telling us that we’ve beat global warming, or at least that the Filchner-Ronne Ice Shelf in the Weddell Sea is safe from collapse for another year… What do you think?
