Look at the blocking graphics today, over the area of my interest in Antarctica.  The blocking pattern has changed, but it still extends 1985 through all years to 2016.  The sea ice changes every year, but the blocking pattern, and the clouds, stay unchanged.

Some of the odd shapes in 2006 are visible again.

And the big black rectangle is visible again.

This is not cloud, not natural features.  It is deliberate blocking.  The co-ordinates are at the bottom of the screenshot if you want to check it for yourself.  Use the timeline in Google Earth Pro to check out 2006.

Why has the area of blocking changed?  No idea.  Maybe whoever is responsible is embarrassed to have been called out.

P.S.   appointment with the boiler inspector next Monday.
