Record Agricultural Yields Should Allay Climate Fear

By Vijay Jayaraj

Countries all over the world are surpassing previous records for production of food crops. This is good news that stands in stark contrast to the apocalyptic picture that the media paints daily in reports on climate and weather.

Because food is fundamental to human survival, even a slight increase in its price can significantly affect millions – even billions – of people. “When food fails, everything fails,” said Geraldine Matchett, Co-Chair of the CEO Alliance on Food, Nature and Health.

So, it is not surprising that the purveyors of fear present climate change as the biggest threat to the world’s food security. Endlessly recycled articles and TV programs constantly peddle the misinformation that a supposedly dangerously warming Earth poses a risk to crops or is already destroying them.

However, in the real world, data show historically high crop production all over the globe. This is because climate change has aided in the proliferation of food crops, as well as other vegetation. Abundant harvests continue to affirm this. As in previous years, 2023 is expected to produce records for agricultural production in many countries.

Wheat is a major source of calories, protein and essential nutrients, and it is relatively easy to grow and store. A reliable source of food in many regions, wheat is the staple crop for an estimated 35 percent of the world population.

After a year of supply uncertainty due to the war in Ukraine, wheat production is slated for a global increase. In the UK, for example, wheat production in 2022-23 is expected to increase by 450,000 tons from the previous year. In the U.S., winter wheat has been planted across nearly 37 million acres, up by 11 percent from the prior year and the highest in eight years.

In Africa, Zimbabwe produced a record 375,000 tons of wheat in 2022, making the country self-sufficient. The new record is 13 percent higher than the previous year and surpasses 50-year-old records. This saves the country 300 million dollars that otherwise would have been spent on wheat imports.

India is second only to China in wheat production. The Indian government reports that wheat production will reach an all-time high of 112 million tons in the 2022-23 crop year.

“The prospect of the wheat crop is better due to current weather conditions and slightly higher acreage,” The Economic Times reported..

In fact, globally, there has been a steady increase in yields of wheat as measured in tons per hectare, with some of the highest being in China.

Wheat Yields

Crop yields in the 21st century have been increasing due to a combination of factors. Among them are the use of modern technologies, the development of high-yielding crop varieties through plant breeding and genetic engineering and the application of fertilizers.

Nonetheless, the level of production would not have been possible without the post-Little Ice Age warming of the earth since the 18th century and the modern increase of atmospheric CO2.

Greater warmth has allowed for longer growing seasons and the cultivation of a wider variety of crops. Higher CO2 concentrations have helped plants to photosynthesize more efficiently, resulting in increased growth and crop yields.

Even in the worst-case scenarios of alarmists, where temperatures rise sharply, global agriculture can adapt through genetically advanced food crop varieties that are resilient to extreme droughts and high temperatures.

There is simply no reason for alarm over climate’s impact on global food production either today, next year or in 100 years. In fact, climate is aiding crop growth and helping the world to feed growing populations.

Good report by Vijay, and it illustrates two important things the CAGW loonies never talk about Mitigation versus Adaptation as regards sea level and weather, and simply planting earlier and harvesting earlier regarding agriculture. Never mind the Reality that humans cannot control climate changes, they can adapt, if necessary by Natural Selection.

There IS a reason to be concerned about Climate Change affecting crop growth.
In most cases CC Will positively affect crop production levels (positive = increased)
While Climate Change Policies will negatively affect crop production by eliminating the use of Nitrogen based Fertilizers as well as reducing available atmospheric fertilizer levels

Yes, that is correct, but about 10,000 years ago, 6,000 years before Stone Henge, about 5 million humans on this world were living in thatched huts and caves, hunting animals and fishing, wearing animal skins for clothing, sewn together with tendons.

That changed for a small veneer of elites, aka nobles, and their knight mercenaries, while 99% of others were living in squalor until plentiful fossil fuels came along in the 1870s.

“Record Agricultural Yields Should Allay Climate Fear”

And if there was a modicum of honesty in the media and politics on the issue, they would. But…

“how the climate crisis is causing food shortages”

“Global food supplies will suffer as temperatures rise – climate crisis report
Politicians around world continue to respond to report from Intergovernmental Panel on Climate Change”

“We know that climate change affects all sorts of things – and one of them could be our food supply.
At the moment, around 40% of the country’s food is imported.”

So, what do they do to bring more UK soil under the plough to reduce that dependence on imported food?

“The 4.2 mile (6.76km) Mallard Pass Solar Farm”

“The government has pledged to relax restrictions on building onshore wind farms in England after a threatened rebellion from Conservative MPs.”

So, you can grow more food whilst simultaneously taking land out of production for wind and solar and rewilding. 

It’s pure doublethink. Surely, others get that? Conservative MPs are in it for the money.

The author shouldn’t say that yields are increasing because of climate change. Slightly warmer temperatures, higher CO2 ,expanded use of fertilizer and diesel farm equipment are the reasons for the increase.

“The author shouldn’t say that yields are increasing because of climate change.”

I agree with you.

I don’t think the author is linking climate change to CO2, but one can get that impression from the way it is written.

I think the author is linking climate change (warming) to increased yields, and separately, is linking CO2 to increased yields, not linked to any warming, but due to the fact that increased CO2 in the atmosphere enhances plant growth all on its own..

When I see a Vijay Jayaraj byline, I’m almost certain his article will be on my daily list of the best dozen climate science and energy articles I recommend on my blog every day of the week. This article is no exception.

Vijay usually provides new insights about Asia. Today he pointed out that Climate Howlers make this claim: “So, it is not surprising that the purveyors of fear present climate change as the biggest threat to the world’s food security”

I realize that Climate Howlers make data free predictions of doom as a habit, but with all their false predictions I try to refute, I didn’t realize food security was a popular subject.

The data on food production contradict such claims and more CO2 in the atmosphere can only improve plant growth.

It seems there is no limit to Climate Howler false claims about climate change.

The Howlers will make climate change claims that contradict their own government data, confident the media will never fact check them and confident that most of the general public believes government bureaucrat scientists, and government granted scientists, only speak the gospel.

These delusions apply to masks to prevent disease (false) and the false claim that Covid vaccines are safe and effective. And the Mexico border is not open to anyone, and any drug, that wants to waltz into the US.

Lying is the normal way for leftists — they can’t help themselves. Truth is not a leftist value, and never was. Censorship is a leftist value, along with scaremongering on a variety of subjects, where the “solution” is ALWAYS more government.

With global overheating carring at current pace, the Antarctica would be only suitable place for high yield agriculture. Just few more ‘Londons’ calving off and we are almost there.

The Alarmists and their ubber wealthy funders/controllers know, crop yield improvements over the very period they want to declare a Climate Crisis, gives the public a very adverse attitude to their Alarmist doom monger preferred narrative.
To resolve this very good outcome in crop yields over the past fifty years, the Alarmists are demanding a ban on all synthetic fertilizer produced using fossil fuel. Basically, that is a ban on all fertilizer. The impact of their (climate alarmists) latest demand, is complete collapse of the food chain/ The test run has been seen in Sri Lanka recently.
The Climate Alarmists have already successfully convinced governments across the Western world to ban secure energy supply. The result of that effort, will be poverty and hypothermia for many old people in the Northern latitudes. The effect of their fertilizer ban and then farming ban to follow, is death from starvation for millions.
That is what is being proposed by these so called Eco Warriors.
We must resist their malign objectives at every turn.

I notice that at the same time fertilizers are being banned those same countries are trying to do away with farm animals, which, of course, provide alternative fertilizer. Ergo, the prohibitions are actually about cutting food production and bankrupting farmers.

They can start using the bodies as fertilizer until a balance is achieved. Remember the stories about planting a fish with each grain of corn to help the harvest?

This is a direct consequence of rising CO2. Only three crops are C4: sugar cane, maise, and sorghum. All the rest —including wheat, rice, soybeans, all fruits and vegetables, alfalfa— are C3 and directly benefit from rising CO2 levels.

Besides warmer weather, longer growing seasons, and CO2 greening of the earth,

There will be more precipitation. IPCC AR4 Chapter 10 page 750

There will be more arable land. Hardiness zones have shifted northward Link

Hardiness zones? Shift? Not where I live.
I have lived in central Washington State since 1989. I don’t know where that map comes from but it is not representative — and it doesn’t say what the criteria are. Some maps use average low. That’s not appropriate. There is no proper legend. Here is a better one:

Thanks for the link. It took a little bit to find a decent then and now hardiness zone and it would have been great to find a then and now blinky. Any way, as we all know, climate does change and it sure does look like those 8 zones have gotten wider and shifted northward into Canada. In other words, it looks like there is more arable land in North America than there was ten years ago.

A warmer climate allows for earlier planting of crops.
As Vijay Jayarai shows quite graphically that climate change is not affecting cereal production .
Looking at his graph there has been a steady increase in yield for 60 years.
Improved crop varieties have helped and also far better and bigger machinery has helped to get crops planted at the right time .
Increasing CO2 levels have also helped and also a far better range of herbicides to control weeds if left unchecked will severely suppress yield .
By far the largest increase in yield is because of the use of nitrogen fertilizer .
That is a fact that Green peace and the Green parties refuse to acknowledge.
The graph that Vijay has supplied starts in 1960 which was when the use of Urea and Diamonium Phosphate was first introduced to the farming world .
Nitrogen fertilizer grows food to feed 4 billion people on this planet and Green Peace is fighting to get nitrogen fertilizer banned .
Let you be the judge of what is the biggest threat of creating a world wide famine ?
Climate change or Green Peace .
