I see that particular issue is concerned
with warm ENSO effects--I did not read much
of it--as it only took about five seconds to
see that it is was not consistent with the
latest research--but thanks for the url,
and welcome to the thread!

Currently the Pacific is in the cold phase
of ENSO (El Nino-Southern Oscillation) and
perhaps also entering a long cycle (20year)
where it will also be in a cool, or negative
Pacific Decadal Oscillation. I had the
opportunitiy to see a fellow from the University
of Washington speak at the NOAA campus here in
Seattle about a week ago--unfortunatly, little
is known about the PDO...so no modeling and
predictions are available.

I'm a bit of a snow freak--like a lot of the
forecasters in Seattle. Would love to see
negative PDO and the frequency of La Ninas
increase, not only would that be good for the
ski seasons here, but perhaps good for the
salmon as well. So far so good, last winter
heavy snowpack and runoff...looks like this
winter will be wet again--if not the record
breaker of last winter.

Global warming is pretty convincing, til it
goes away. Let's see if El Nino returns in a
year or two. Til then, no worries in the Pacific
Northwest--in fact, only January and September
of this year recorded above normal temperatures,
otherwise it's been cool, and even our mountain
snowpack of last winter is not entirely melted.

Who knows, maybe in twenty years some of our
lost glaciers will have returned.
