The new paper
has been accepted
for publication
by the online
Journal of
"Geophysical
Research:
Atmospheres".
This summary
is based on
an abstract and
press release,
not reading the
actual paper.
My only message
is that climate science
is far from being
"settled science".
If it was
"settled science",
then we would not need
climate scientists !
Speaking for Wu, et al,
Ms. Wu says:
“(climate)
Driving forces
include the sun,
the atmosphere,
and its interaction
with the ocean,”
“We have detected
no evidence
of human influence.
But that doesn't
mean we can
just relax and
do nothing.”
Their findings confirmed
an earlier study by another
team of Chinese scientists,
published by the online journal
Scientific Reports in 2014,
which first detected the
500-year cyclical pattern
of China’s summer monsoons,
and linked it to solar activity.
The 2014 research
was based on 5,000
years’ of data, and
suggested the current
warm phase of the cycle
could terminate over the
next several decades,
ushering in a 250-year
cool phase, potentially
leading to a partial
slowdown in man-made
global warming.
Wu said the latest study
had 10,000 years’ worth
of new data, providing
a better picture of the
500-year cycle.
The new data suggested
the impact of the sun
on the Earth’s climate
may be greater than
previously thought.
Ms. Wu said variations
in solar activity alone
were usually not
strong enough
to induce the rapid
changes in vegetation
the research team
recorded in
the sediment cores
of Moon Lake.
The scientists found
the warming impact
was amplified by a
massive, random interaction
between surface seawater
and the atmosphere in the
Pacific Ocean, known as
the El Nino-Southern
Oscillation (ENSO).
Wu said she was
now more worried
about cooling
than warming:
“A sharp drop
of temperature
will benefit nobody. "
"The biggest problem is,
we know it will come,
but we don’t know
exactly when.”
