Perfectly true and quite irrelevant.

So why is there so green-inspiured much fuss over it ?

1. It is an indicator that there is goobal warming that
will do worse things in the future.

Why do you assume that a warming world has to be 'worse' ?
I'm enjoying the warmer winters in particular and it results
in reduced energy use too.

A warmer world will also have warmer summers. Thankfully,
winters
should warm more than summers in most parts of the world that
have both as far as I understand things.

Meanwhile, there is such a thing as people and regions that
have a worse
time with summers than with winters.

2. Replacing sea ice with sea increasesabsorption of
sunlight, so this is a positive feedback mechanism for
global warming.

The incident angle of sunlight at the poles means that this
is a minor effect.

If one merely neglects atmospheric absorption, incoming
radiation at the
poles exceeds peak at the equator about 70-72 days of the
year and average
at the equator about 74-75 days of the year. After what the
atmosphere does to incoming solar radiation, I surely expect
this to remain being significant.

Gee, neglecting one of the most important factors in evaluating
ground received energy flux does not sound like good science to
me.

He didn't neglect it, merely estimated that the somewhat longer
path length wasn't going to make enough difference to matter in
what was an essentially qualitative exposition.

I was neglecting longer atmospheric path length only because
that causes
some reduction of an effect that remains quite significant.
So a day's worth of unclouded sunlight on the North Pole in late
June
may be roughly the same amount of incoming solar radiation, maybe
slightly less as opposed to 22-23% more than what the equator gets
during an
equinox. I think that is still significant.

You really need to recheck your geometry. Intercept angles.
