Antarctica Ices Up to an All Time Record

So, expressed as a percentage of ocean cover, the decline going on in the Arctic is almost 25 times the increase going on in the Antarctic. Walt Meier, a top scientist at the snow and ice center, told me, “It should be pretty clear that the change in sea ice in the Arctic is much more substantial than what is happening in the Antarctic.”
We’ll do similar math for the winter maximum in Antarctica. In the first five years of the satellite era, the average sea ice peaked at 91.9 percent of the surface of the Southern Ocean. In the most recent five years, counting this record-high year, it increased to cover 92.9 percent of the ocean.
How does that compare to the trend in the Arctic for the same season? I’ll spare readers another deluge of numbers, but in percentage of ocean cover, the decline in Arctic winter ice is eight times as fast as the increase in Antarctic winter ice.
 
What this warmist fails to mention throughout his EXTREME effort to play down the record sea ice in and around Antarctic is that Antarctica holds over 90% of the worlds ice.   But, that's not what's really important.  Bishop Hill points out the IPCC report which cited the following PDF article:

Just in the opening abstract is this little gem:
The climate change projections over the 21st century reveal that the annual mean sea ice extent decreases at similar rates in both hemispheres...
 
Oops!   Maybe it isn't "pretty clear" that the change in sea ice in the Arctic is much more substantial than what is happening in the Antarctic...unless it is convenient.
