Antarctica , Sea Ice, Ice Sheets and Wind Excuses

Over at the LA Times they are making excuses for why there is record breaking sea ice in Antarctica.

One of the excuses is that “global warming is strengthening circumpolar winds”.  There is very little evidence that “global warming” would actually increase wind. Any change in winds is tenuous and could be cyclic.

However, the trouble with that excuse is that an increase (or change caused by cycles like the AMO/PDO etc)  in circumpolar wind in Antarctica would prevent snow accumulation and cause ablation of the ice surface which would then appear as “melting” and it would be nothing of the sort.

Sea Ice Data is late today – Aug 30 2014

UPDATE: Data has been published

Normally the NSIDC Sea Ice Data is posted on their site at 6:51am Pacific Time.

Some days it is late or isn’t updated until the next day.

The MASIE data gets updated about 7:17am Pacific. It was updated … but it is the previous days data.
