The Australian Bureau
of Meteorology (BOM)
says weather station
sites did not move
... even when they did.
Warming at
these four sites
alongside the
Great Barrier Reef
is due to site changes,
incompetence,
poor record keeping
and “adjustments”:
All along the coast near the
Great Barrier Reef, the BOM
has claimed temperatures
have warmed in the last 50 years,
and they’ve calculated it to
a tenth of a degree.
The BOM keeps long pages
of site descriptions and
"exact" dates of moves
and equipment changes.
Historic photos show
the BOM records
are wrong.
The BOM will swear a site
was in the same place for decades,
but photographs and archives
show the site was often moved
as developments sprang up
around them.
The BOM didn’t keep
decent records.
Even though warming
can be caused by:
-- The weather station
moving to a warmer location.
-- Replacing the old standard large
230-litre Stevenson screen (wood box)
around it with a small, warmer inside,
60-litre screen.
-- No one cleaning the dark dust
and grime off the white screen.
“The notion that the Great Barrier Reef
is threatened by climate change
and warming depends on incompetent records, unjustifiable ‘corrections’, super-sensitive thermometers in smaller boxes,
and neglected sites”
says Dr Bill Johnston,
who documents weather station
sites the Bureau of Meteorology
can’t seem to find time for.
He uses aerial and satellite photos,
and ground based shots
from the national archives.
The BOM says the climate
is the most important issue
for life on Earth.
But it isn’t
important enough
for them to document
that thermometers
keep moving,
and the area around
the thermometers
keeps changing ?
BOM stopped answering
Dr. Johnston's questions,
and he finds it difficult
to get published
in meteorology journals.
The BOM holds raw
temperature data,
is the ONLY team
that analyses them,
and makes political
statements
about them.
Only the BOM knows
what the instruments
are really measuring,
and won’t explain how
and why they "adjust"
the raw data.
In fact, the raw data
files are deleted.
The methods are secret,
and the BOM has
never been audited.
Bill Johnston has
started publishing
his precise, unpaid work
on his own website.
Bill Johnston is independent.
“Despite all the catastrophism
and free money, there is no evidence
that the climate of the Great Barrier
Reef has changed or is likely
to change in the future”,
says Bill Johnston.
Johnstone has investigated
more than 300 of Australia’s
most important long term sites,
and 80 of supposedly top notch
ACORN-SAT sites (which is
about 75% of them).
-- Across Australia no
weather station sites
have stayed the same
-- they’ve all moved
-- Large 230-litre Stevenson screens
(wood boxes) have been replaced
with faster responding small
60-litre ones;
-- Automatic weather stations
(AWS) have replaced thermometers;
-- New sites have opened using
PVC-screens (instead of wood boxes
painted white) in the hottest places
they could find;
-- Observers have changed.
-- BOM saves money
by not mowing the grass
or cleaning the white
screen's dark dust
and grime.
“Australia’s
warming
is mostly due to
poor maintenance
and electronic
thermometers
operating in
small Stevenson
screens”,
Dr. Johnston said.
“Evidence that the Bureau
adjusts their datasets
to support the warming
narrative is unequivocal.
... sometimes they recognise
a site change, sometimes
they don’t; it’s a
non-random pattern.
Many forgotten site changes
create a trend they can blame
on the climate".
“For instance, at Gladstone, they replaced the radar; cleared the bush and installed a 60-litre screen 30-metres away; sacked the staff, demolished the office and its unsurprising that as instruments are no longer regularly serviced and cleaned, temperature has increased relative to the climate”.
At Cairns as well. They didn’t know what happened at the Post Office or that the original aerodrome site was located beside the old apron. They said that in December 1992 the site moved 1.5 km northwest (to the other side of the runway). However, they forgot that it moved to a mound near the centre of the airport in 1966 and that it moved again before September 1983. Also, as one was bulldozed to build the other and no data was missing, another site must have opened in the interim.
The 60L boxes are too small to allow all the equipment to operate at it’s best. The highly sensitive electronic thermometers at the back are barely 2cm away from the hotter north facing side of the screen. They will record one second spikes in temperature, and the Bureau of Meteorology accepts these spurious spikes as new “hottest day ever” records."
The Bureau claims the Townsville airport weather station has absolutely not moved: There are no documented moves until one of 200 m northeast on 8 December 1994”. However, the site moved at least three, possibly four times while it was on the eastern side of the main runway and probably twice between January 1970 when it moved to a mound on the western side and the most recent move to the AWS. By pretending the site didn’t move before 1994, they attributed trends and changes in the data to the climate.
Similarly at Rockhampton, where before it moved to a mound near the middle of the airport in about 1956, the original Stevenson screen was near the airport’s northern boundary beside the USAAF garrison and canteen. Warming caused by a satellite communications module installed close-by the second site in 1986 was ignored to imply it was due to the climate."
