So far, I’ve looked at three approaches used by climate
denialists: to blankly deny that anything is happening to the climate, to distract from the topic and to minimise the effects and/or evidence. The fourth that I have identified is to
ignore, to ignore the whole topic (which is more of a denier tactic than a
denialist one) or to ignore selectively (in other words to cherry-pick).
Ignorance is a key element of the other three
approaches, but I think it’s worth bringing it out as a separate approach in
itself – because cherry-picking is such an important part of the denialist
effort. (I did mention cherry-picking in
On Climate
Denialism - Deny Deny Deny! and Misdirection
and Misinterpreting the Climate
and Climate
Emergency? What Climate Emergency?
and, well, quite a few earlier articles on climate change).
First, consider the denier. Note that a denier is not a denialist – where
I have defined a
denialist as “someone who has
taken the time to review at least some of the available climate change data
and, for whatever reason, rejects enough of it reach a position that climate
change is not real, or is not anthropogenic, or is not as serious as it’s being
made out to be” and a denier is “an ignorant person who just denies the
existence of climate change (to some extent) based on information taken on face
value that was originally sourced from a climate denialist”.
There’s a certain amount of
synergy among denialists, they take information from each other so they could
be called deniers to the extent that they don’t check each other’s work.
I would go so far as to say
that all deniers ignore the majority of the information out there
on climate change. They don’t go to the
reports that the UN’s Intergovernmental Panel on Climate Change (IPCC),
they don’t go to NASA, or NOAA, or any local body responsible for monitoring the
climate (Australia, United
Kingdom, Sweden, Germany, France, South Africa). They might,
however, watch some local equivalent of Fox News or read some local version of
the Murdoch press (News Corp) and shape their opinions based on the advice of
people who are possibly less ignorant, but who have been particularly selective
in what information they have taken on board.
Denialists don’t have the
luxury of passively ignoring all the information available to them, instead
they need to have an idea of what is out there so that they can actively ignore
that which is inconvenient and carefully carve out factoids that support their
case.
An example of this relates to
the Federation Drought, which was actually a number of droughts that ran into
each over around the year 1900, when Australia was in the process of federating
into one country rather than remaining as a few colonies of the United Kingdom.
A family member sent me a post
to what looks very much like an astroturf group, Farming in Australia for real farmers and supporters. (noting that the full stop is part of the name of the
group). This Facebook group was set up
by a(n unsuccessful) right-wing politician who stood for the Shooters,
Fishers and Farmers Party.
Now there are two ways to
approach something like this. The first
is to track down the origins of the post, which was presented to me like this:
History is a useful unless it's ignored or even overlooked
" CLIMATE CHANGE"
During the 7 year period from 1896 to 1903, before the vast land clearing, Industrial Revolution, before the first world war, and the second world war, before the millions of cars were on the road and the vast amount of coal mining to date, and the Green Party, I was looking at this period and here are some of the facts from the period.
. Rainfall for this period was 46% below the previous wet period
.Federation Drought, Heatwaves, Bush Fires and Dust storms, associated with 40% livestock losses in Queensland.
.Livestock numbers in Queensland reduced from 6.5 million to 2.5.million (cattle), and from 19 million to 7 million ( sheep).
.Western New South Wales, impacted by soil erosion, and woody weed infestation (1898-1899).
.Properties in the Western New South Wales were abandoned with collapse in carrying capacity, resulting in the Royal Commission investigating financial stress in the Western Division.
.Sir Sydney Kidman acquired properties, and nearly lost all by 1901, due to severity and wide spread nature of this drought.
.Tropical Cyclone Mahina struck Bathurst Bay ( Cape York) on the 4th March 1899, the surrounding region suffered a massive storm surge from the category 5 system, killing over 400 people - the largest death toll of any national disaster in Australian History.
Reports recorded that grass was ripped from the ground on the islands offshore and that fish and dolphins were left in trees,15 metres above sea level
This all happened before the new catch cry of "GLOBAL WARMING", and "CATASTROPHIC".
The words they use now to frighten the public.
Puppet Palaszczuk should look back at previous records to see what has happened in years gone by, and order an enquiry into the recent fires in National Parks, she would then find it is the incompetence of National Parks management. Instead of making wild statements, GLOBAL WARMING.!

I sympathise with the devastation that farmers and public have endured over the past few years. Is this a matter of history repeating it's self.

There is enough idiosyncratic
wording and punctuation in the text that it’s not going to be too hard to see
where it really came from. Perhaps it
really was written by a Queensland farmer called Bernie
Jackson (albeit on 26 October rather
than 27 October 2019), but no. I found
that it was written by Rex Berry (according to Colin Boyce on 1 March 2019), by Angelina Nic (on 28 October 2019), by NighthawkNZ (on 27 October 2019), by Stand Up For
Australia-Melbourne (on 1 March
2019), by Bernie Delany (on 12 November 2019), by Claude
Bedrossian (on 11 November 2019),
by Climate Truth (on 21 October 2019), by Cronin Ken (on 18 January 2020).
A snippet of it also appears to have been written by Chet McAteer (on 9 January 2020).
This is the sort of thing that you see when someone has a barrow to
push.
I had to dig deep to find
that, apparently, Rex Berry was the original source, but it’s been
spread wide and thin ever since – with that post being shared more than 19,000 times. Most of his other posts get one or two shares
although another one, about the climate and bushfires did get twenty-six. It’s not hard to comprehend why some people
are tempted to post inflammatory stuff about climate change.
Another approach, the one I
actually took with my relative, is to address the content of such a post. It’s worth a reminder that I am talking about
how selectively ignoring facts and evidence is a key element to being a
denialist. Much of what Rex wrote is
true enough.
The Federation Drought did happen. Having followed a particularly wet spell, that
drought was perfect for contributing to bushfires (a lot of growth followed by
an extended drying out period, leaving plenty of readily ignitable fuel) – and
there were some major bushfires in 1896 and 1898 which denialists are keen to
point out, while skilfully ignoring that in 2019 (but not in in the 1890s) we
had aerial support, modern firefighting ground vehicles, radio communications
and a regime of fuel reduction.
There was a
Category 5 cyclone in 1899, Mahina, although dolphins 15m up in trees appears to be a
bit of an exaggeration (or misremembering of dolphins being found on 15m
cliffs).
Rex argument pivots on the
reader being ignorant with respect to a number of key facts: no-one is denying
that Australia has experienced droughts regularly in the past, Mahina was a one
in two to three hundred year storm (more on Mahina in a moment), climate
scientists have not categorically stated that there is a direct link between
climate change and drought frequency and severity in Australia and climate
scientists have instead indicated that storms may in fact decrease in number,
although they are expected to increase in intensity.
As I responded to the person
who sent me Rex Berry’s work:
No-one
is suggesting that intense storms haven’t happened in the past. The fact
that there was one in 1899 is immaterial. The question is more about what
is happening in general with storms over the past 100 years or so. I
have, coincidentally, been researching storms and the following is salient:
if
we look at Cat 4 hurricanes (in the Atlantic), we see:
Which
does seem to have a distinct trend to it. If we did something similar
with Cat 5s, it would look like this:
Which
again appears to have something like a trend to it.
and:
In
IPCC report AR5 Part A,
there is reference to Severe Storms:
Severe
storms such as tropical and extratropical cyclones (ETCs) can generate storm
surges over coastal seas. The severity of these depends on the storm track,
regional bathymetry, nearshore hydrodynamics, and the contribution from waves.
Globally there is low confidence regarding changes in tropical cyclone
activity over the 20th century owing to changes in observational capabilities,
although it is virtually certain that there has been an increase in the
frequency and intensity of the strongest tropical cyclones in the North
Atlantic since the 1970s (WGI AR5 Section 2.6). In the future, it is likely
that the frequency of tropical cyclones globally will either decrease or remain
unchanged, but there will be a likely increase in global mean tropical
cyclone precipitation rates and maximum wind speed (WGI AR5 Section 14.6).
Note
that there was a prediction that the number of storms will (likely) decrease.
What we see, however, is the number of storms remaining about the same, but the
strength of them increasing on average, leading to a greater number of higher
rated storms. The Atlantic has a higher concentration of storms than
other basins (this might be why Magellan gave the Pacific its name, ie the [relatively]
calm ocean) and there are twice as many cyclones/hurricanes in the
Northern hemisphere than the south
(probably due to the Northern
being the warmer hemisphere).
Additionally,
the Atlantic is much smaller than the Pacific, which means that storms that are
generated there are more likely to make landfall at full strength and that is a
key also to the newsworthiness of Mahina.
Mahina made landfall at Cape York while at Cat-5 level (note that of
Pacific storms, which are by definition North Pacific Storms, only 18 have
reached Cat-5 since 1959 and none
of them made landfall – no-one cares too much about a super storm that only
happens at sea [well, seafarers and fishermen, perhaps]. It’s entirely
possible that no-one would remember today Mahina if it got to Cat-5 out in the
middle of the Coral Sea and made a less intense landfall).
There’s
another question though, why was that cyclone particularly bad?
It
was because two factors combined to make it so:
It
wasn’t just one storm, it was two. Therefore, it was a bit of an outlier
(a 1:200 to 1:300 year event) and should not be taken as indicative. If
we start seeing storms like this every second year, then we ought to start
worrying.
Picky
I know, but the industrial revolution is more commonly said to have started in
1760 (at least the First Industrial Revolution), with coal production rising significantly in the
1790s (to feed steam engines). I think the author may be referring to the
second industrial revolution, also known as the Technological
Revolution which was, in part,
dependent on the introduction of fossil fuels on a major scale, with petroleum
taking off in the 1850s. I know Australia tends to be behind on some
things, Queensland doubly so (with waking up to the climate change related
issues being one of those things), but I don’t know how this guy can think that
1903 was before the industrial revolution. The first railway in Queensland
opened in 1865 and the steam train was a product of the industrial
revolution. They didn’t use donkeys to pull the trains:
That
is definitely a steam locomotive, although initially wood or coke was the
fuel. The locomotives began being converted for coal burning after an
edict by the Commissioner
for Queensland Railways in December 1870.
Other
than that, the author appears to have dug up the Federation Drought, which we
already know about, and tried to present it as something new. We have
droughts in Australia. Note that the link between climate change and
drought is nuanced. Warmer air holds more water, which could mean that
some areas which are currently particularly drought prone will become wetter
(more tropical), while other areas, further south and nearer the coasts, will
become drier and more prone to drought. The AR5 findings were:
· Low confidence
in an observed global-scale trend in drought or dryness (lack of rainfall)
since the 1950s, due to lack of direct observations, methodological
uncertainties and choice and geographical inconsistencies in the trends;
· High confidence
that the frequency and intensity of drought since 1950 have likely increased in
the Mediterranean and West Africa (although 1970s Sahel drought dominates the
trend) and likely decreased in central North America and northwest Australia;
· Low confidence
in attributing changes in drought over global land areas since the mid20th
century to human influence owing to observational uncertainties and
difficulties in distinguishing decadal-scale variability in drought from
long-term trends;
· High confidence
for droughts during the last millennium of greater magnitude and longer
duration than those observed since the beginning of the 20th century in many
regions.
In
other words, increased drought in Australia is not a climate
change prediction. So, the fact that we had a long drought a hundred and
twenty years ago, give or take, is immaterial. (Note: the possibility of
human drivers on drought is raised as an emerging area of research – it’s not a
claim that humans caused the droughts now or in the past.)
---
I have great confidence that
Rex Barry was entirely ignorant of most of that and that it was that ignorance
that enabled him to put together a post that gave him his fifteen minutes in
the spotlight.
More well-established
denialists, such as Tony Heller, Joanne Nova and Anthony
Watts (basically anything where he writes about “the pause”), are unlikely to be so comprehensively ignorant and
instead they aggressively cherry pick, even the more scientifically inclined
collaborators have been shown to cherry pick. Note that the
fact that these people are masters of cherry picking does not stop them from
accusing others of cherry picking, in fact it’s one of their favourite
accusations.
