Climate Change causes largest ever Australian wheat crop

When will it end?

Suffering Australian farmers have had to harvest the largest total volume of agricultural produce since records began, highlighting how stupid it is to let coal plants keep releasing vital plant nutrients into the atmosphere.

Australia’s bumper crop: record agricultural production forecast to total $78bn

The Guardian

Agricultural production will be the largest total volume of commodities Australia has ever produced, with a historic gross production value of $78bn, the Australian Bureau of Agricultural and Resource Economics and Sciences is predicting.

Just one week ago on Reuters:

EXPLAINER: Is climate change boosting hunger around the world?

Weds December 1

LONDON, Dec. 1 (Thomson Reuters Foundation) – As a warming planet brings higher sea levels and wilder weather – from droughts to floods – the challenge of growing food is getting tougher with less reliable harvests.

Climate Change destroys investigative journalism.

    It’s good that the natural increase in atmospheric CO2 has improved crop yields. Atmospheric CO2 was becoming so low that life itself was threatened because plants require a minimum CO2 level of 150ppm.

    On the other hand, global temperatures appear to be dropping which will lead to food shortages. Australia will fair very badly during cooling because of our obsessive commitment to expensive and unreliable “green” energy. In addition, if global cooling leads to less rain, Australia will again suffer because of a failure to build dams, pipelines and other irrigation infrastructure.

      “It’s good that the natural increase in atmospheric CO2 has improved crop yields. ”

      You’re suggesting a single event in a single country is due to an increase in atmospheric CO2 generated by natural causes. Are you serious? You like so many others including the author of this article are confusing weather with climate.

      How about the rest of the world? Or is the “natural increase in atmospheric CO2” focussed solely on Australia? How did other major wheat producing countries fare?

        Selective use of data. Without going in chapter and verse, Canada’s two record years for wheat were 2016/7 and last year…so the CO2 argument holds. Also total global wheat production 2020/21 was greater overall than the previous year, an ongoing trend.

            Well done GA, you finally realise that human development goes hand in hand with human use of carbon based fuels. !

            You just got the cause and effect the wrong way around.

            Stop the use of carbon based fuels, humankind development will stall…

            … by 2050 apparently !

            It seems don’t understand enough about plant biology to realise that CO2 is an essential ingredient, currently at lowish levels, and that the gradual increase of atmospheric CO2 is just what the world needs for continued food production efficiency.

            Trying to liken that plant requirement to IT, car making etc is just plain ga. !

          “Also total global wheat production 2020/21 was greater overall than the previous year, an ongoing trend.”

          Selective data?

          You clearly are not taking into account the estimates that the harvested area for wheat in the 2020/21 global campaign will increase 2 per cent year-on-year to 221 million hectares. That has considerably more impact year on year than does CO2.

          Nor are you considering IGC estimates that the harvested area for wheat in the 2020/21 global campaign will increase 2 per cent year-on-year to 221 million hectares and that global grain production has come a long way in the last 40 years, thanks to the broad adoption of vastly improved agronomic practices.

            Odd that a biologist would try to downplay the effect of CO2 on plants. 😉

            Maybe forgotten the basics of plant biology ?

            Perhaps some data will help ?

            http://www.co2science.org/data/plant_growth/dry/dry_subject_w.php

            The CO2 values are ” increases for a 300, 600 or 900 ppm increase in the air’s CO2 concentration above ambient conditions.”

            Nearly 40% increase in wheat dry weight for an increase of 300ppm in atmospheric CO2.

            And if you took the atmospheric CO2 level up to around 900-1000ppm (600ppm column), you would get around a 63% increase.

              Here’s some real life data Clarence. The atmospheric concentration of CO2 from 2000 to 2021 has increased by 12.2%. The global harvest of wheat from 2000 to 2001 has
              increased by 32.8%. A ratio of yield to CO2 increase of around 2.75 compared with the ratio 0.66 from your dates of

              The data you link to show an increase of 100% in CO2 concentration leads to an increase in wheat growth 0.66 which is considerably less.

              These data suggest there are factors that, collectively, have a greater effect on wheat growth than does CO2.

                Seems you don’t understand that the growth is to do with “available” CO2, so the real starting point for CO2 should be about 200ppm, where plants shut down

                Try again. A biologist should know better.

            Ian,
            Climate is the time-weighted-average of weather. Saying the two aren’t related is like saying ants and an ant-nest are two different things. If you don’t understand weather you don’t understand climate. All the examples of failed wheat crops you gave were from the northern hemisphere. They have had cold winters over the last few years and unusually cold Spring and Autumn seasons – the very times they need to plant and harvest their grain. They have had another cold Autumn. How does that fit into global warming?

        The farms in the USA are operated to reflect what seems to be the future demand and income. Thus, crops planted and harvested can change quickly.
        Corn and soybeans are displacing small grains where the growing conditions are appropriate. However, world wide small grain harvests are increasing.

        ” that naturally occurring CO2 is responsible for the record wheat harvest”

        A biologist would know that nearly all plants respond with better growth and yield when they are subjected to higher atmospheric CO2 concentrations.

        It is “almost certain”, to use IPCC slang, that raised CO2 level are at least partially, but “highly likely”, significantly, responsible for the generally increasing crop yields around the world over time.

        As your links point out, cold and/or lack of water are the main contributing factors to lower crop yields.

        160

      • #
        Strop

        Obviously there are weather variables that assist or stifle crop production and likely have a greater impact than whether CO2 is 300ppm or 400ppm. But, whatever the weather, surely you agree that more CO2 is beneficial to crop yield.

        You can post links showing poorer crop yields in any given year or location due to weather. But none of your links say that crops yields are lower because of an increase in CO2.

Now who would believe that rubbish? Lucky we have you to set the record straight. Ha ha ha. No wait, at 0.04%, it is a trace gas, it does fertilize ALL plants and there is no evidence that it drives climate. Please explain Simon?

        Simon, during the day plants absorb CO2 and release O2 due to photosynthesis. During the night plants absorb O2 and release CO2 due to respiration. Some arid environment plants absorb CO2 at night also by a process called crassulacean acid metabolism.

        Don’t worry, your comments have that effect on everyone else..

        Your comments show a distinct and complete lack of comprehension of anything to do with the operations of CO2 in the Earth’s atmosphere and biosphere.

        It has been shown many times at 250ppm CO2 is borderline low for plant growth, and that even at 420 ppm that is well below the optimum level for proper plant growth

        And you have never been able to produce one tiny bit of real science that shows that the highly beneficial rise in atmospheric CO2 has caused any of the nice warm period in which we are currently lucky enough to be living in.

        “and can’t possibly affect the climate “

        We await your scientific evidence that it does.

        ….. and wait, and wait….. and wait..

        There is plenty of evidence that it has zero effect on global temperatures, you have either missed that evidence, or been incapable of comprehending it.

        It doesn’t trap radiation. it permutes it to different frequencies that escape through the atmospheric window.

        https://i.postimg.cc/50scywD8/radiative_change_2.jpg

        It doesn’t affect the atmospheric lapse rate, therefore does not affect the temperature lapse or atmospheric pressure gradients, and since net energy transfer is based purely on those two items, it is scientifically impossible for even quite large changes in atmospheric CO2 to have any effect on temperature whatsoever.

      2008 This drought may never Break
      It may be time to stop describing SE Australia as gripped by drought and accept the extreme dry as permanent.
      “Perhaps we should call it our new climate” said Bureau of Meteorology Head of Climate Analysis, David Jones.

      2010 Floods in northern NSW (and SE Queensland)
      2011 Brisbane Floods January. a wave of brown water inundated the city in the biggest floods to hit Queensland’s capital since 1974
      (The Guardian 2013 Floods in Australia 2010/11 lowered the world sea level).
      2015: the Hunter region, along with Central Coast and Sydney, was lashed by wild weather. It brought heavy rainfall and disrupted power supply to over 200,000 homes. The storms led to some of the most significant flooding that many residents in the region had experienced in 60 years 2017: Heavy falls were recorded along most coastal districts of New South Wales.
      2020: major flooding in Qld and NSW
      2021 40,000 evacuated from flood zones.The Bureau of Meteorology warned cells like this could become more regular throughout the rest of summer, following the wettest November since records began. He said more rain on the way.

      The overnight drenching prompted Queensland Premier Annastacia Palaszczuk to officially rule out water restrictions this summer.

        I learnt recently that the Australian continent is the only one where freshwater runoff into oceans does not follow the rain or snowfall like the other continents. It is the only continent where the variation in water storage beyond an annual cycle is significant.

        This fact is a compelling reason to improve water security in the country. There is huge variation in annual rainfall and drought dominates.

              So Gympie continues to flood every few years and Queensland needs to ration water every few years.

                I guess Australia is more bowl shaped country than most. 🙂 Without a central mountain range, and with a section “below sea level” perhaps most of Australia doesn’t “drain to the sea” as quickly.

                “Australia is the lowest continent in the world with an average elevation of only 330 metres. The highest points on the other continents are all more than twice the height of Australia’s highest peak, Mount Kosciuszko which is 2228 metres above sea level.”

                Percentage of Australia below sea level = 0.11

                https://www.ga.gov.au/scientific-topics/national-location-information/landforms/elevations

                Probably our high variable rainfall and high evaporation rates means the whole continent can dry out some years.

                Not all our rivers flow out to sea. When there is a drought on land there is also a drought in the sea – no water is flowing to take essential nutrients to the microscopic flora and fauna in the ocean. These microscopic life forms provide the essential services of a carbon sink and oxygen release to the atmosphere.
                Australia has a giant subterranean dam which we need a serious rethink about. It’s called the Great Artesian basin. Massive slow moving rivers run inland when the rains come, such as the Diamantina and the Coopers, recharging the basins as the rivers move toward Lake Eyre, 9 meters below sea level. I’m fully supportive of dams , but I do believe that we have a mind set that is not compatible with the way our island continent operates.

    Here Willis Eschenbach explains that everyone is much better fed, clothed and housed today because of the increase in crops etc around the world. This is also the main point of Dr Rosling’s video for all Humans from 1810 to 2010.

    And farmers and farm workers make up a very small percentage of the workforce today compared to 30 years ago or 50 years ago or 100 years ago. Here’s the link and his quotes.

    https://wattsupwiththat.com/2021/04/25/wheres-the-emergency/

    “Yields of all major food crops continue to rise, and humans are better fed, clothed, and housed against the vagaries of weather than at any time in the past.

    And it’s not just yields that are going up. Despite the gradual warming since 1965, humans are better fed than ever. And this is a very valuable measure. Measures of income and wealth can get distorted because one person can make fifty times the income as another, or own fifty houses to the other’s one house.

    But nobody can eat 50 breakfasts, so average food consumption measures the nutrition of the whole population, rich and poor alike. Here is the consumption of protein, calories, and fat for all the regions of the world”.

      BTW I should’ve noted that Willis has included a number of graphs for crops etc over the years at the link above.
      Very easy to prove that we’re living in the very best of times.
      Don’t forget that population in 1970 was 3.7 bn and today is 7.8 bn and yet everything has improved over the last 51 years and by a huge margin.
      And certainly no obvious, detrimental crop losses from droughts or floods around the world over many decades.

      Yes Geoffrey+ Williams and just think of the unbelievable increase in calories+cropping, housing, clothing ( or wealth/ GDP) etc around the world since 1970.

      In 1970 global GDP was about 2.5 Trillion $ and by 1990 about 18.4 trillion and by $ 2000 about 33.5 Trillion $ and today about 84.7 Trillion $. Yet the Glasgow loonies + Biden+ Bojo + UN etc have just told us we have a CRISIS or EXISTENTIAL threat hanging over our heads and we must wreck our economies ASAP.
      Of course if anyone believes their idiocy they’ll believe anything. AND THEY OBVIOUSLY DO BELIEVE IT.

    But Jo, it is just a prediction.
    “Agricultural production WILL be the largest total volume of commodities Australia has ever produced, with a historic gross production value of $78bn, the Australian Bureau of Agricultural and Resource Economics and Sciences is PREDICTING.”

    Lets see what the actual value is when the crops are harvested and sold.

    The curious thing is that it is the cool & wet climatic conditions which are generating this level of production.
    Of course the Guardian is unable to admit or even recognise this.
    it has to keep banging the drum that CO2 causes GOREBULL Warming.

    As Einstein once said “theory determines what facts ya see”.

        The ABC reporting seems to be focussing on how much of the harvest has been lost in the east due to the recent flooding etc.
        Also, that $78bn figure must be based on some forecast values, but since China has stopped buying our grain crops, those values are very unpredictable.
        Why dont they judge crop production in Tonnes, rather than $$$s …a more accurate measure.?

    Australian Bureau of Agricultural and Resource Economics and Sciences (ABARES) still doesn’t know how much rain damage will impact on their predictions, and they won’t know until the wheat is actually in the silo.

    ABARES executive director Jared Greenville said “it would be the first time in at least half a century that production will increase for so many products at the same time”.

    Minister for Agriculture and Northern Australia David Littleproud said “production is expected to increase for every major livestock commodity and almost every major crop, our farmers are expected to produce the largest volume ever.”

    Dr Greenville said while heavy rain in eastern Australia has led to harvest delays and some crop losses, it’s unlikely to have a significant impact on Australia’s national harvest tonnage.

    “The larger impact will be on grain quality, with a higher than usual proportion of the crop being lower-value feed-grade wheat,” he said.

    . . . the upgrade of the Australian crop to a bin bursting record of 34.429 million tonnes, an increase of 1.8 million tonnes from the September projections.

    The report found La Nina conditions will see above average rain continue to fall in eastern and northern Australia bringing with it good growing conditions in 2022.

    If forecasts are realised, Australia’s agricultural production will reach a record $78 billion in 2021/22, with the most valuable winter crop ever expected worth $22.3 billion.

    We have now also seen the Canadians increase the size of their bread wheat crop by 700,000 tonnes, to 16 million tonnes, when a reduction to below 15 million tonnes had been expected.

    The Russians however are doing it tough.

    Climate Change causes largest ever Australian wheat crop

    Not so much climate change but rather favourable weather and more CO2 in the atmosphere. Neither could possibly be regarded as “Climate Change” so I take the heading as being cynical.

    There are subtle changes in climate but they are barely noticeable.

    60

    TdeF

    I am increasingly staggered about how prominent Climate Change is in the news. AGL is hell bent on closing Liddell. Dr. Twiggy Forrest is trying to make another fortune from Hydrogen. Even elections are about Climate Change as Holmes a Court and other rich listers try to pack the parliament with people sympathetic to saving the planet from something which you can see has not happened in 33 years, but is now super super urgent?

    It is really perplexing to understand whether these people actually believe what they are saying or they just want a piece of the next gold rush?

    Seriously, how can anyone believe in rapid sea level rise? Or rapid Global Warming? Or this unbelievable urgency and crisis and even ‘extinction’? Or that windmills or solar and batteries can replace fossil fuel power in Australia? Or that CO2 is somehow dangerous when everyone, every second of the day is breathing out 14% CO2. And the extra 6 billion people on the planet in 100 years has obviously not devastated the world’s climates? Really, a 50% increase in CO2 in 170 years is not a big or rapid change, less than 3% a decade no matter how you draw the graph. And it’s nothing compared with the rise in the population of 700%.

    Or it could be a religion, but I really doubt it. Consider the rich and most famous and successful opportunists of history and their children are now into Climate Change as the next big thing and you have to think they do not want to miss out. Or you could take the view that they have already made enough money and are into philanthropy. I am sure Alan Bond would be into Climate Change in a big way. With other people’s money.

    It’s odd though that Twiggy did not demand miners pay massive new diesel taxes (removing ‘subsidies’, tax ‘reform’) when he was one. And now he wants the money raised to be given to a good cause. His own project. It’s as if he does not want to risk his own cash and wants the people of Australia to fund his hydrogen adventure?

      Correction needed.. Human breath contains around 4% CO2, not 14%.

      Everything else you said is spot on.

      Its so anti-science and anti-reality as to have nearly reached the “bizarre” stage.

      70

        TdeF

        I have read the 14% figure, but it is hard to find again. It is likely an upper limit. Of course it cannot exceed the incoming 21% figure for oxygen except for a short period.

        The amount and % of CO2 varies, of course, with exertion levels. 4%-5% is a resting minimum. 3.8% is pushed by Wikipedia but what
        proportion of humanity have desk jobs?

        The total volume goes up dramatically as well “When you jog at 6 mph, you need 10.2 times the resting oxygen requirement”

        But you also start using anaerobic energy which means more CO2 per breath. That is you can move without breathing, dramatically
        increasing CO2 levels when you do finally breathe out. Holding your breath in exercise will do this, or very heavy exertion.

          In fact it is fascinating. All the numbers from a few years ago are gone and almost every article on a Google search is about Climate Change, page after page and the contribution of human breathing. Real science has been buried under a mountain of denial that humans actually contribute to CO2 by breathing. And that an extra 6 billion people is of no consequence. Nothing to see here folks. But they are missing the point.

          Simply I would have thought human caused CO2 output should at least scale with the human population, not least by breathing but also by travelling, working, building, eating, burning and just working. From that point of view the 50% increase in CO2 attributed to humans and the industrial revolution should be much higher when the human population has increased x10 in the same period and the CO2 produced per human would have gone up greatly too, as we see in the demand for massive increases of energy in China.

          So why is the CO2 increase only 50%? It is pretty obvious the cause is natural and not human activity or it would be much higher.

    Yesterdays news was the announcement from BlueScope steel and Shell cosying up for a proposed “Green” Hydrogen plant at Port Kembla to supply the steelworks.
    A 10MW Electrolyser facility to split water to feed the steel plant.
    But, some details were missing. ..
    .source of rge Green electricity ..? ( presumeably a Solar/Wind /Battery, farm ?)
    ..how the Hydrogen would be used in the steel mill ? ..Heating ? Steel conversion ?
    ..how much (if any) truely Green Steel this would produce ?
    …how it would affect the cost of steel production. ( this would be a $100m project )
    Basicly , just a PR exercise to drum up support for Govmt funding, i suspect.

    Currently there are now 3 of these 10 MW Hydrogen Electrolyser projects in the pipeline , with over $100m of public money invested in them
    Note ….there are No 10MW Electrolysers operating yet anywhere in the world !

    It’s unbelievable that no warmists seem to understand that more CO2 (whatever its source) is good for plant productivity.

    Also, the atmosphere will remain perfectly breathable for oxygen breathers up to 8000ppm CO2 which is the limit imposed for submarines by the US Navy although normal operation is 2000-5000ppm.

    No warmist seems to be capable of demonstrating in a real open system such as the atmosphere that CO2 causes warming.

      Yes, it would be hard for anyone to demonstrate the heating effect of a greenhouse with no glass in its frames !

    And , further Govmt support for renewables..

    the NSW government revealed that it had received an “overwhelming” 11GW worth of pumped hydro project proposals in response to a call for storage options to help the state’s “renewable energy revolution”.

    According to NSW state treasurer and energy minister Matt Kean, 28 different sites have been proposed for potential pumped hydro projects in response to a relatively modest $50 million of grant money up for grabs under its Pumped Hydrogen Recoverable Grants Program.

    The 11GW worth of project proposals is more than five times the estimated 2GW the government needs to support the more than 10GW of wind and solar projects that are also beign sought by 2030 in its planned renewable energy zones.

    11 GW from 28 proposals suggests that none of them will be more than 500 MW max, ..
    ….and someone should tell them the important metric for pumped hydro is the “capacity” in GWhrs..
    No point in having 500 MW of power if it only lasts 4 hrs !

      No point in having 500 MW of power if it only lasts 4 hrs !

      It is useful down to about 2 hours storage. Anything that gets through the evening peak could provide an economic return. If it is fast response then it can give stability benefits as well.

      Substantial curtailment during the middle of the day in SA yesterday and today:
      http://nemlog.com.au/gen/region/sa/
      Significant curtailment in Victoria today and some yesterday:
      http://nemlog.com.au/gen/region/vic/

      Curtailment is often occurring because of the cost of keeping the system stable. The intermittent pay about 50% of the FCAS charges and these are now eats into the benefit of the LGC subsidy.

      Any pumps in SA and Vic today could be paid to consume power:
      https://www.aemo.com.au/energy-systems/electricity/national-electricity-market-nem/data-nem/data-dashboard-nem#price-demand

      The LNP government in NSW has not been as gung-ho with its “renewables” subsidies as SA and Victoria but it appears it is now drinking from the same fountain of faith as the Labor camps.

        Rick, remember that the plan is to have 82% RE grid power by 2030…..presumably much of that will be solar. .?
        So, sure a few hours of PH may help with the evening peak , but it doesnt do much for the following 8 hrs until the Sun starts chipping in again, or the early am peak if you have drained the PH for the evening exercise.
        Somehow, they have to cater for the still, windless, nights…and overcast days….
        …..and we know batteries wont cut it !

          remember that the plan is to have 82% RE grid power by 2030

          South Australia has managed to get to 60% on the back of the big battery otherwise known as Victoria over 20 years and it is a tiny part of the NEM. NSW, Queensland, Victoria and Western Australia do not have their own “Victoria” to use as a big battery. No way can adequate storage be built in 9 years.

          Labor’s “plan” is like the “greenhouse effect” a fairy tale. It might make entertaining reading but it will have no substance. AEMO are just realising that the only way to model the power supply system is a stochastic model based on 5 minute time intervals using currently available time run intermittent generation data with some Monte Carlo randomness thrown in. It has taken them 20 years to get to that realisation and is the main reason power costs are always higher than predicted. Current models are based on capacity factors and the diversity fairy, which has often been absent across the NEM.

    What can I say? Us aggies are very efficient. Its not all due to the weather of course or even elevated CO2 levels. Aussie farmers are probably the most efficient, unsubsidised primary producers on the globe. Big uptakers of technology with huge improvements in machinery, genetics, crop protection, analytics, quality control all the time. Also Aussie farmers have ALWAYS farmed in a variable climate, which is something I find infuriating with a lot of the crazy AGW/climate change supporters. They seem to think that in past decades/centuries the farming conditions in Australia were akin to something from a Bambi movie. That Mother nature is some kind ,benign, caring creature. Whereas anyone who has spent any time on the land will know- first chance, she’ll kick you fair in the gonads. This is also the incorrect perception provided by the likes of CSIRO and state department of ag/primary industries.
