Sea Ice - more melting

I've added to the table at the ice/temp update page. It now includes the 2012 NSIDC numbers from here. They are on the right, in purple (h/t Neven).

NSIDC doesn't update as promptly as JAXA, so I've just put the total following the last day's difference reading. NSIDC also seems to be noisier.

However, both are showing rapid melting currently. JAXA stands at 4.664 m sq km, only about 0.4 m above the record 2007 low, and it has lost 0.377 m sq km in the last three days. The NSIDC index is showing a similar situation.
