I've noticed for a few weeks now how the global SST anomalies are
generally +ve in the north and -ve in the south. I was wondering whether
this has any significance to global patterns to come?

As global warming causes the amount of arctic sea ice to decrease,
models show the heat equator being displaced northwards. Eventually we
are likely to end up with one pole ice free. (This has happened in the
past.)

Who says? And how do you define past? In monkey world or in reality?

The cycle is probably self limiting proof of s divine intelligence as
we are all still alive despite ourselves. It ould seem that the storms
seen chasing up the side of Norway instead of impaling themselves on
the nice receptive fjords like they are supposed to, are providing a
long term solution - or should I say sediment:

Like any other type of phytoplankton, coccolithophores are one-celled
marine plants that live in large numbers throughout the upper layers of
the ocean. Unlike any other plant in the ocean, coccolithophores
surround themselves with a microscopic plating made of limestone
(calcite). These scales, known as coccoliths, are shaped like hubcaps
and are only three one-thousandths of a millimeter in diameter.

What coccoliths lack in size they make up in volume. At any one time a
single coccolithophore is attached to or surrounded by at least 30
scales. Additional coccoliths are dumped into the water when the
coccolithophores multiply asexually, die or simply make too many
scales. In areas with trillions of coccolithophores, the waters will
turn an opaque turquoise from the dense cloud of coccoliths. Scientists
estimate that the organisms dump more than 1.5 million tons (1.4
billion kilograms) of calcite a year, making them the leading calcite
producers in the ocean.

Perhaps these SST maps are showing signs of this occuring.

Interesting thought, although surely in the interim this would have the
opposite effect with the faster melting pole(s) in the summer months
introducing colder waters and an increased -ve SST anamoly. Whereas in
winter the SST's would appear more +ve with less ice forming than of the past.

I take your point, but the rate of ice melt is probably quite slowing
now, so the cooling affect less than say June/July.

As the apparent difference in the pressures of High and Low systems
seems to be self limiting (in that negative NAOs seem to provide mild
weather and extremely positive ones seem to produce stormy extremes)
might it be that after a period of negativity, the system will right
itself?

But is that what the world wants?

Take a look at earthquakes archives for when the NOA is negative. The
planet seems a lot more stable and a lot less dangerous in them. And
who doesn't like mild winters and warm summers?

Well, apart from farmers. And even then I bet they prefer the weather
to be nice f there was no crop damage involved. Perhaps they aught to
be encouraged to grow fruit trees.

It's been exceptionally good for plums and berries this year. Maybe
there are more of these negative vibes and they aught to be preparing
for it.

Why do I get the impression that the state would rather hang muslims
than sort all that out? And why did the wet-knickers at the BBC pick
this particular moment to give up on meteorology altogether?

(Apart from Peter Gibbs of course -but he can't hold out forever.)
