Aussie Climate Scientist Predicts Rainfall Will Change

Guest essay by Eric Worrall

Aussie Climate Scientist Steve Sherwood, Director of the Climate Change Research Centre at the University of New South Wales, thinks in the future Australia will experience more rain, less rain or something in between.

More rain on the horizon as climate change affects Australia, study finds

Australians will need to batten down the hatches with more intense rain storms predicted as a result of higher humidity driven by a rise in global temperatures.

New findings from the ARC Centre of Excellence for Climate System Science, published in Nature Climate Change on Tuesday, reveal that a two-degree rise in average global temperatures would lead to a 10-30 per cent increase in extreme downpours.

The study’s authors predict that while some parts of the continent will become wetter, others will experience increasing drought.

Steve Sherwood, a professor at the Climate Change Research Centre at the University of NSW who contributed to the research, said global warming would have a clear impact on rainfall.

“There is no chance that rainfall in Australia will remain the same as the climate warms,” he said.

“With two degrees of global warming, Australia is stuck with either more aridity, much heavier extreme rains, or some combination of the two.

The study referenced by the press article;

Future increases in extreme precipitation exceed observed scaling rates

Models and physical reasoning predict that extreme precipitation will increase in a warmer climate due to increased atmospheric humidity. Observational tests using regression analysis have reported a puzzling variety of apparent scaling rates including strong rates in midlatitude locations but weak or negative rates in the tropics. Here we analyse daily extreme precipitation events in several Australian cities to show that temporary local cooling associated with extreme events and associated synoptic conditions reduces these apparent scaling rates, especially in warmer climatic conditions. A regional climate projection ensemble6 for Australia, which implicitly includes these effects, accurately and robustly reproduces the observed apparent scaling throughout the continent for daily precipitation extremes. Projections from the same model show future daily extremes increasing at rates faster than those inferred from observed scaling. The strongest extremes (99.9th percentile events) scale significantly faster than near-surface water vapour, between 5.7–15% °C−1 depending on model details. This scaling rate is highly correlated with the change in water vapour, implying a trade-off between a more arid future climate or one with strong increases in extreme precipitation. These conclusions are likely to generalize to other regions.

Sherwood’s University of New South Wales is also home to Climate researcher Chris Turney, leader of the infamous 2013 Ship of Fools expedition to the Antarctic.

Sadly the full study is paywalled. But from the abstract and Sherwood’s comments to the press, in my opinion Sherwood’s prediction seems unfalsifiable. Almost any imaginable future rainfall observation would fit a prediction of more aridity, more rainfall, or something in between.

Not only rainfall, the whole climate will change. This doesn’t even qualify for an Ig Nobel Prize.

SMC

It might qualify for publication in JIR (Journal of Irreproducable Results) though.

” the ARC Centre of Excellence for Climate System Science,”
When you have to call yourself “excellent” rather than letting others judge that from your work, it’s pretty clear that you know you are not excellent at all. It signals that you know you are mediocre and the best you can do the change that is some pathetic verbal attempt at self-promotion.

That’s the one journal that would never publish this piece as the results cater for every contingency.

Hivemind

It would be difficult to find any results to reproduce, though. Paywalled is a pretty good indicator of junk science.

Next you’ll be telling me that Politicians don’t have my best interests at heart or that the mainstream media doesn’t report the unvarnished truth.

So, as the climate warms, the atmosphere is capable of holding more ambient moisture…Certainly it would, warmer air can always hold more moisture than colder air. Problem is, those proposed storms would also be warmer and less moisture would Rain Out because their warmer air mass would still want to retain that proposed greater moisture content. So the average rainfall ammounts should still remain relatively constant even whithin the scope of a warmer environment

Following the link to that Sydney Morning Herald story:
“Professor Sherwood warned that current policies worldwide are not enough to meet the Paris targets.
The study found that a four per cent rise in global temperature, possible based on current increases in the rate of carbon emissions, would lead to a 22-60 per cent increase in extreme rain storms.”
A four per cent rise in global mean temperature would be a rise of 11.5 degree Celsius.

Sorry Stephen Sherwood, the percentages are wrong. The climate scales in K, not deg.C. The Paris accord is based on changes of 2-4 deg C, which is approximately a 0.15% change in average temperature. Given 10-20 deg. C or more of local daily variability of variability, none of the temperature records have any chance of finding a change in He–that small.

@philohippous Thanks for pointing out the most basic bit of 8th grade math+science which seems beyond the ken of many on all sides of these discussions . Only in 0 based scales can ratios be discussed . All of these purported effects are asserted to be caused by near noise level , 0.3% , variations in estimated temperature , only a fraction of even our peri- to ap-helion variation . It’s all utter embarrassingly , determinedly bad nonscience .

Rhoda R

Can’t go wrong with a prediction like that.

Douglas

He says:
With two degrees of global warming, Australia is stuck with either more aridity, much heavier extreme rains, or some combination of the two.”
Sherwood, deep in the forest seems pretty safe with that – 2 degrees of global warming seems far enough away from happening to dodge the sheriff of Nottingham makes it hard to see the wood from the trees – maybe long enough to make his getaway from the rope.

richard verney

If the globe warms 2 degrees, by how much will Australia warm?
What are the predictions, what are the predicted weather fronts?

MarkW

The dry parts will warm more than average.
The wet parts will warm less than average.
The average parts will remain average.

Bunyip

How can you ever take Climate Scientist seriously ? I am embarrassed to be an Australian.

Menicholas

The good news is, the ones not to be taken seriously have been doing an outstanding job of identifying themselves.

Hivemind

Don’t be embarrassed to be an Australian, but you can be embarrassed that the Australian Government is paying money for this crap. When Abbott was in, there was an attempt to clean up this cesspit. That ended when Turnbull pushed him out. I wonder who was behind that little bit of knifework?

Don’t be. Governments around the world have been lured into supporting this sort of nonsense. My predictions are that parts of Australia will have prolonged drought, other parts will experience strong storms and heavy rainfall, others will be cold in winter, and other parts hot at times. But, oops, that’s what it always has been like. And Aussies have always coped.

“If the rainfall doesn’t change it will remain the same”.
Beat that for a prediction.

Predicting is hard, especially about the future.

John Harmsworth

It seems falsifiable to me. I spilled rye and coke on my computer and it says the next hundred years of Australian weather will look just like the last hundred. A few record highs and lows, similar rainfall patterns and same average temps. I’m willing to put some money on my bet if the good professor will do likewise. Plus a bottle of premium Canadian rye whiskey against whatever +2.5 toxins they suspend in water down there.

I predict that if it rains more, things will be wetter, except when it rains less, when things will be drier, maybe.

Menicholas

But, on the other hand, it could rain more often, and over a wider area, but do so less intensely.
He seems to have overlooked that possibility.

jorgekafkazar

This is a joke, right?

Hivemind

Of course it’s a joke, it’s climate science. And your taxes paid for it.

Geo Jones

Afraid not jorgekafkazar, we have University’s full of them here, mores the pity from a concerned but ageing scientist.

Geoff Sherrington

At those Aust sites we have studied, there is usually a stats link between local daily rainfall and temperature that can account for up to 50% of the variance of temperature. Does rainfall drive temperature? Does temperature drive rainfall? Both each other? Neither?
For examples of the problems, link to see Sydney Observatory http://joannenova.com.au/2017/01/sydney-observatory-where-warming-is-created-by-site-moves-buildings-freeways/
When Sherwood mentions the words “puzzling variety of climate scaling rates” would that be entirely expected because the data are plainly not fit for the purpose he seeks with erudition more than common sense?

Macha

Well Geoff, there are a few like me that say pressure drives temperature…and wind moves it about. junk article seems most accurate prediction.
I was amused by local weather reports that says 50% chance of rain. To me, that meant even chance it will or won’t, but apparently it means half my suburb has 100% chance of rain. Doh?!

joelobryan

Unfalsifiable “scientific” claims are of course pseudoscience.
This guy Sherwood might as well get out his Tarot cards or Ouiji board and prognosticate about changing climate and rainfall patterns. They’ll give same or better results as his “models and physical reasoning” predictions.

Here is my recommendation for Dr. Sherwood’s next generation climate calculator.

I note that the human race has all grown significantly taller in the past 200 years. Global warming?

“11% more rain” sounds costly (not!). But almost always the carbon loons have to imply some kind of extreme economic cost to climate change. The alleged future costs are supposed to scare us. But the truth is that if there were any climate costs at all to CO2 those would be minimal, and pale in comparison to the upwards of $1 trillion a year we’re already spending on the leftist scam.
What about the benefits of CO2, like arguably many trillions of dollars a year in increased agricultural productivity, benefits which far outweigh any future costs by orders of magnitude:
Tom Nelson @tan123 https://twitter.com/tan123/status/821004381621538817
.@Maribellasmom No offense, but the notion of CO2-induced starvation is utter #ClimateScamBS:comment image

Chris

What is the basis for your statement ” arguably many trillions of dollars a year in increased agricultural productivity, benefits which far outweigh any future costs by orders of magnitude.”?

D. J. Hawkins

I’m sorry, did you miss the graphs, all showing an increase in crop yields as a function of time or are you just invincibly ignorant? Many in fact show a sharp increase in yield growth around 1950, at which time the IPCC claims CO2 production began to affect climate. Live by the assumption, die by the assumption.

Rob Bradley

D. J. Hawkins, nice graphs, and they do show a correlation. As you well know, correlation is not causation. Tell me how you were able to eliminate things like improved irrigation, increased fertilizers, new crop strains and superior weed control from your graphs?

You are right in your trade figures, but there is far more to food than merely the income generated from just selling it. I have extracted the food energy per capita per day for developing countries from the FAO data. In 1960 it was 2054 and in 2015 it had climbed to 2980 Kcal/person/day. This huge and welcome increase greatly improved the longevity, health and productivity of the people. Most African countries are now amongst the fastest developing countries on earth – thank goodness – whereas once they were regarded by external agencies as being hopeless basket cases. There are many factors that have contributed to this wonderful development (aid is probably one of the weakest “driver”) but improved CO2 concentration is certainly very important as studies going back many decades have indicated. Plant productivity has been severely limited by CO2 depletion in the past, even in corn fields in the US. Improved food availability has had massive beneficial effects on the developing world. None of these benefits are adequately captured by simple trade figures.

Chris

DJ Hawkins, first, the trend lines in the graphs are a result of many different factors – increased use of fertilizers, better strains of wheat, etc, increased use of irrigation, better crop techniques (like zero tilling to reduce topsoil erosion). Assigning all of those to CO2 is not valid. Second, as I noted below, the entire agricultural industry globally is $3T, so saying “many trillions of dollars a year in increased agricultural productivity” is not true.

Chris

The entire global agricultural industry produces US$3T a year, and yet you are saying CO2 alone has increased that by many trillions. http://data.worldbank.org/indicator/NV.AGR.TOTL.CD

Dan Hawkins

And,
what if the World bank is measuring in long scale trillions, while Eric Simpson is talking short scale? Plenty of misunderstandings arise from these two different naming conventions.

Hivemind

I just noticed that 11% more rain bit. If that is what is being promised, then I say bring it on. Australia is a dry country and would benefit from 100% more rain.

old construction worker

“prediction seems unfalsifiable” Maybe, maybe not. I bet someone has already looked into rainfall patterns from the Minoan, Rome warm period and MWP. I know, you don’t have to say it. “But this time it’s different”.

Bryan A

Well of course it’s different now. Roman Warm Period Then it was CO2 @ 280 ppm today it is CO2 @ 405 ppm. Then it was 300m people, now 7.3b people so lots of changes

David S

From a scientific perspective I would more trust the words of Dorothea Mackellar’s my country.. ” I love a sunburnt country , a land of sweeping plains, of jagged mountain ranges, of droughts and flooding rains. ”
I think this pre AGW poem pretty much describes Australia’s climate future and its past.

Nice.

Okay, no problem,,

Then all we will have to do is ‘geoengineer’ some parts of Australia to bring the water from the wet areas to the dry areas.
They are called ‘canals’. Problem solved.

SoCal already does that on a grand scale. They are suckin’ the Sierra’s plumb dry (unless they get above average rainfall every year). (The Lake Wobegon theory, where every kid is above average intel).

With electricity prices going through the roof, farmers paying for their water here in OZ, and this being the biggest supplier of bass load power and irrigation https://en.wikipedia.org/wiki/Snowy_Mountains_Scheme The only thing the government needs to keep this running at full speed is rain. This technology WILL be used http://www.australianrain.com.au/assets/files/PDF/UQCombinedQLDreport.pdf to keep the system full, while other areas suffer the consequences.

Early success
“In 1946 USA researchers I Langmuir and V Schaefer reported that rain could be induced by seeding clouds with dry ice. While many reacted cautiously to these claims Bowen immediately saw the potential importance of the technique for dry Australia. Within months, two members of his staff had investigated Langmuir and Schaefer’s work and, on their return, had carried out a trial in eastern New South Wales using RAAF aircraft. Success was immediate – the date was 5 February 1947.”
https://csiropedia.csiro.au/cloud-seeding/

Very interesting. At one point it is implied the world would be on average at -18 deg C instead of +18 but for global warming – man made, of course. And the oceans are absorbing heat from the atmosphere. And an extraordinary graph shows an alarming increase in the likelihood of hot days, whereas a cursory glance at the historical data for my locality on BoM website shows no change in the last century and a mean temp rise 2 deg give or take, which is close to there being no significant increase due to man-made activities, although it is only commonsense that some of the rise is caused by mankind. In every interglacial period for the last 800,000 years temperature ice cores (mainly EPICA Dome C, but also Vostok for 450,000 years) show that the rise in temp has preceded increases in CO2. That’s eight cycles. Every glacial period starts when CO2 is at a maximum. The climate so called consensus ( a very unscientific principle) has no explanation for this. We are currently only 15k years after the last glacial period. If the earth was not warming now we would be in serious trouble.
Globally incidence of extreme weather has not increased in relatively recent times, the earth is visibly greening, crop yields are increasing. This is what has happened since the 1970s when scientists were warning us of dangerous cooling trends. There has been no global warming for about 20 years depending on how it is measured although CO2 has increased. We need to wait 3-5 years now to see whether, after the 2015/16 El Nino, leaves us with steady, increasing or cooling temperatures. All the IPCC models run hot by significant amounts compared with actual data and there is no empirical data showing either that warming is dangerous or that if we stop all man-made emissions it will make any difference – even the IPCC agrees with that. And yet trillions of dollars are poured into research in order prove these obviously wrong models are actually correct. this is not science. It is a belief in magic. money is available only if your aim is to do this.
I wonder what Australia has done differently from the rest of the world to have this uniquely dangerous postulated climate based on demonstrably incorrect models..

No honest self respecting climate scientist can be specific about Weather except to observe natural cycles and say they will repeat. CO2 Cannot be a forcing Function, but instead is s following function, in concentrations many times what humans contribute. The forcing function cycles big enough to influence Earths climate are on the scale of cosmic disturbances, Solar Disturbances, and Solar system alignments. For an integrated theory on a scale bigger even than ENSO that actually describes observed historic long term cycles, including little and major ice ages, see blog at Paullitely.com, in Particular the blog that begins with “How in the Universe”.

Robber

2 degrees of warming. But aren’t the predictions based on warming since pre-industrial times? So we have already warmed 1 degree – what catastrophes can be attributed to that change? And how much difference will 1 degree make, from an average of 16 to 17 degrees, when we already have parts of the world doing very well with averages of over 20 degrees (like Dallas), and others with averages around 10 degrees (like London).

tony mcleod

You bunch of tools.
I wonder what Australia has done differently from the rest of the world to have this uniquely dangerous postulated climate based on demonstrably incorrect models.
These “predicted” changes have been obvious for years. The rightly saying they on all the evidence available are likely to change further in these directions – different outcomes in different places
Take you about 5 minutes of research to show that NOT ALL OF AUSTRALIA IS GOING TO EXPERIENCE THE SAME EFFECTS. IT IS A LARGE CONTINENT.
Even though that appears to be the single problem that Eric ‘the worlds leading climate scientist’ Worrell has with it.

The first part is correct tony, the second, no. It is a small Continent. The smallest in fact. Geography play the greatest roll in Australia’s weather. Just as it does in the America Southwest. As well as other areas.

Arctic sea ice is good, hey.. Shows we are getting slightly back towards the norm for the Holocene.
A RECOVERY from the massive expanses of the Little Ice Age.
1979 was up there with that EXTREME LIA level, did you even know that ???????.
Unfortunately that recovery isn’t going to last. The slight drop in the Arctic is because the wobbly Jet Stream has sucked some of the frigid cold air elsewhere.. like USA, Russia Europe.
And the Antarctic is heading back up towards its norm for this time of year after a brief but quite normal dip.

Robert B

The internet is slow at the moment so I can’t find the reference but AR4 does state that the modelling shows that relative humidity * will remain close to the same in a warming world.
“Australians will need to batten down the hatches with more intense rain storms predicted as a result of higher humidity driven by a rise in global temperatures.” So not only do the predictions cover all possibilities, the models predict no change in relative humidity and a large change if the conclusion calls for it (or maybe its the very wet La Nina year)
* the percentage of water vapour in the atmosphere might increase but the percentage of the saturated value (which increases with temperature) shouldn’t. Means that the amount of water, on average, that precipitates when hot and humid air hits cold air will be the same as before.

D. J. Hawkins

It would be a question of whether or not atmospheric processes are driven by relative humidity or absolute humidity. A pound of air at 60°F and 50% relative humidity has fewer grains of moisture (39) than a pound of air at 70°F and 50% relative humidity (55).

Greg Cavanagh

D.J. “atmospheric processes are driven by relative humidity or absolute humidity”
Look at the satellite photos of Australia and it’s clear that the Roaring Forties wind and the Ant-Arctic cold drives the Australian weather. Humidity is a local thing and I’m not sure it has much influence at all. Cold fronts are what drive our weather here.

Robert B

Probably not worth getting into. The colder latitudes are meant to warm up more so cold air meeting with warm humid air will result in less cooling and less rain. Only a back of envelope but it does highlight how big a claim it is that warming means more intense rainfalls rather than what would put a smile on aussie faces – more rain.

Robert B

I should add that there is a difference in precipitation in going from 40C at 50% RH to 20C 100% humidity than 42 to 22 (roughly a few %) but because colder regions warm up more, its more likely to be less than even that.

I think it was Professor Sherwood’s magic model that succeeded where twenty-eight million weather balloons over 60 years failed in discovering that elusive troposphere ’hot spot’, an identifying fingerprint of strong positive water vapour feedback in the climate system and hence essential for the catastrophic narrative:

gnomish

Geological history proves cycles of ice ages and inter-glacial periods.
Isn’t that very well accepted science? (you could even call it a consensus)
I would like to ask Steve Sherwood how he reconciles his prediction with geological history and, over what period of time will Australia’s rainfall be “increased”?
Will it cancel out the next ice age?
If not, and the earth continues to warm at the current rate of a poofteenth of a degree per year, won’t the humans alive at the time (if any) in the lead up to the ice age, experience a comfortable “cool period” after the hell-fires of predicted warming?

Actually it was back in March 2015 that Tim Blair christened the ridiculous Bob Ellis with the name Nostradumbarse. But it’s a perfectly good nom de pume for Old Flannelpants.

You’ve got a good archive, Karabar. Do you go back as far as when Tim was writing in The Bullein?

And the null hypothesis is….. ?
*facepalm*

there is none , try asking them what would ‘disprove ‘ their claims and they cannot or will not ever answer .

I truly weep for my country and as for the wankers who keep coming up with this garbage ,” the end of your gravy train world is nigh” .
Just listening to our local news and they were whining about our unusual 40 degree c plus day , the weather presenter then claimed more people die of heat stress than natural disasters .
I checked and you know what ? More people die from heat stress than winning tattslotto and eating their shoes and choking and walking on railroad tracks and even playing on freeways at peak hour .
I kid you not check it yourself Tony , unfortunately they didn’t mention more people die from cold related injurys than heat related injurys .

A complete bunch of nongs. They haven’t got a clue. One day we’re going to have a week of rain & 2 days later, after no rain, well the rains been postponed to next week.
But it’s Climate Change, DOH! I meant Global Warming that’s really causing the problem.
Hey, this is Australia, let’s not get too serious, after all we’ve got Labour party or dead duck Liberal governments.
Might as well stooge them all. Let’s squander the kids inheritance on a mirage of windmills and stupid solar panels.

Actually PaulE it’s spelled Labor Party. Sorry to be picky.

What the Australian Labour Party now spells its name “labor Party”? colour me sceptical!

observa

Yes the founders of the ALP couldn’t spell either but you know how ejumacation is nowadays-

Interestingly the non-science crowd might get their comeuppance next summer once Hazelwood closes-

There’s a cartoon line for this one: “Eenie meanie chilli-beanie – the spirits are about to speak” *SMH*

Classic climate ‘science’ heads you lose tails I win ‘ and if ever wanted to know why these people protect their own areas so much , its party because they never get such a easy job anywhere else and no other area of science would touch them given their rubbish standards. So its all in , because otherwise they have nothing .

And what if the temperature does not rise by 2 degrees, but drops instead?
Another paper, of course!

Perhaps Sherwood could get a job at the Bank of England!!

“A regional climate projection ensemble6 for Australia, which implicitly includes these effects, accurately and robustly reproduces the observed apparent scaling throughout the continent for daily precipitation extremes.”
I think this illustrates the problem. They build a model, tweak it to replicate what has actually happened, then congratulate themselves that they have build an accurate and robust model.
I honestly don’t think they see the problem.

Hivemind

You misunderstand the problem they were solving. The government had money. They wanted it. Once paper later, problem solved.

My prediction for the coming year is that (fill in the blank) will increase, decrease or be somewhere in between, all on account of climate change. You’re welcome!

Roger Knights

“There is no chance that rainfall in Australia will remain the same as the climate warms,” he said.
“With two degrees of global warming, Australia is stuck with either more aridity, much heavier extreme rains, or some combination of the two.”

What he’s saying isn’t a mere truism. He’s saying that if aridity is avoided, and rainfall occurs at current levels, it’ll be in a less benign way.
(But maybe, OTOH, rainfall patterns in Australia will become more benign; i.e., maybe there’ll be a moderation of its flood/drought pattern. Who knows?)

Berényi Péter

The study’s authors predict that while some parts of the continent will become wetter, others will experience increasing drought.

Weather in Australia used to be like clockwork, there were no extremes whatsoever. Not any more.

GregK

if it’s normal is it extreme ?

Perhaps only in comparison to someone else’s normal

I have said it before and I will say it again:
Simulation is like masturbation – the more you do it, the more you start to believe that it is the real thing.
