In the mean time the Arctic, Greenland and the Antarctic keep melting
and ice breaking up. Explain that. Me thinks you are "out to lunch."

No, the Arctic ice is recovering, can't say much about the others but
these things happen normally all the time. Temps go up and down without
human intervention. AGW is treating the planet as if it should be in
stasis.

Wrong! The arctic sea ice recovered slightly from the 2006 minimum but as of
April 2009, it was less in area than 1979-2000 average. Furthermore, the
trend line is a downward slope and the Arctic on average has lost 40% of its
pre 1980 ice. Also, new ice formed is now very thin and is vulnerable to the
present melt season. You delude yourself if you think GW does not exist. The
evidence is clear for anybody with half a brain to observe. See
http://nsidc.org/arcticseaicenews/index.html

Just last week a chunk of ice the size of Manhattan broke of one of the
Antarctic shelves and Greenland is melting at an advanced rate. Because of
the loss of ice the earth's albedo is decreasing causing a positive feedback
effect with increased solar absorption.

The antartic ice is above long term trend:

Antarctic sea ice area is indeed above long term trend of since
observations began, but to a lesser extent in square kilometers than
Arctic sea ice has been running low over the past few years. The world
has experienced a loss of sea ice.

It appears to me that the explanation is that the Atlantic Multidecadal
Oscillation is in a phase that shifts heat northward.

The period of the AMO is about 65, maybe 70 years. Let's see how sea
ice in each polar region is doing 30-35 years from now.
