Guest Commentary by David Archibald
The area planted for corn and soybeans this season is well below historic averages. This was mostly due to waterlogged fields and flooding which precluded planting. The planting windows for corn and soybeans are now closed. The USDA crop progress reports provide weekly updates by state. For example this is the state of the corn crop in Indiana to Monday June 17:
Figure 1: Indiana corn crop progress to Monday June 17.
The emerged crop is one month behind where it was in 2018. Which means that maturity will be one month later at best, assuming that the rest of the summer isn’t abnormally cold.
Figure 2 shows that the same situation in soybeans in Indiana:
Figure 2: Indiana soybean crop progress to Monday June 17.
The current expectation is that the US corn crop will be down 30% on 2018 which will push the price to about $9.00 per bushel at harvest. What could make the situation a lot worse is an early frost. The Corn Belt did warm slightly over the last 100 years due to the high solar activity of the second half of the 20th century. This is shown by the cumulative growing degree days (GDD) of the first decade of the 20th century (blue lines) compared to the first decade of the 21st century (red lines) in Figure 3 for Whitestown, Indiana:
Figure 3: Cumulative GDD for Whitestown, Indiana
Normally, for the 21st century, the corn crop is in the ground by April 27 and the crop has reached maturity with 2,500 GDD well before the normal first frost date for Whitestown of October 10. The earliest recorded date for Whitestown is September 3. That was in 1908. If that is repeated in 2019 the crop will be only 80% through its growth cycle. Yield and quality will be well down and the total crop may be 50% or less of the 2018 level.
The US will be able to feed itself but at much higher prices. Currently some 40% of the corn crop goes to ethanol production and this could be redirected to animal feed without too much trouble. But protein production would still be well down. Each 56 lb bushel of corn used in ethanol production results in 18 lbs of dried distillers grains (DDG) containing the protein. This is used as a feed supplement to pigs, chickens and cattle. Both pigs and chickens have a 25% conversion efficiency of vegetable protein to animal protein. The global warmers want us to adopt vegetarianism in order to save the planet. The public is going to get a taste of that future coming up soon. However animal fat is essential for infant neurological development and brain function so we can’t go completely vegetarian.
What is happening in the Corn Belt is a mini version of the transition from the Medieval Warm Period to the Little Ice Age. The population of Europe exploded in benign conditions of the Medieval Warm Period from 1000 AD to 1300 AD, reaching population levels that weren’t matched again until the 19th century. In fact parts of rural France have less population today than at the beginning of the 14th century.
The breakover from the Medieval Warm Period to the Little Ice Age in Europe had sustained periods of bad weather characterised by severe winters and rainy and cold summers. The Great Famine of 1315 – 1317 started with bad weather in the spring of 1315. Crop failures lasted through 1316 until the summer of 1317. The population decline over the two years is thought to be about 10%, associated with “extreme levels of crime, disease, mass death, cannibalism and infanticide.” These conditions may be less in the Mormons amongst us who are instructed to keep one year’s worth of food in stock.
The Modern Warm Period ended in 2006. Current solar activity is back to levels of the Little Ice Age. To paraphrase Santayana, those who don’t remember history are condemned to being surprised and unprepared when it repeats itself.
A large and increasing number of nations are feeding their population growth with imported grain. That is going to be become more expensive to continue, with or without an early frost in the Corn Belt. Global warming hysteria has been a consequence of very benign conditions for the OECD countries where it is concentrated. That angst will be supplanted by more basic concerns.

Excerpts in italics with my bolds.
They say all politics is local; so is all weather.
So on behalf of my fellow Westerners, I have to ask: What’s up with all this cold weather? It may not be a crisis yet, but in the two weeks leading up to Memorial Day — the traditional start of summer activities — much of the country has been donning sweaters and turning up the heat.
I know, I know. Weather is not climate, and you can’t generalize from anecdotal evidence of localized weather conditions to a unified theory of thermal dynamics, but isn’t that exactly what the climate alarmists have done, on a larger scale, for the past 25 years?
Haven’t we been brainwashed by political scientists (oops! I mean…

Jakobshavn glacier, West Greenland [image credit: Wikipedia]
Even the climate alarm oriented BBC has finally had to admit the inconvenient truth about Greenland’s largest glacier. Instead of dropping in height by 20m. a year, it’s now thickening by 20m. a year. This isn’t supposed to happen when one of the stock phrases of the fearmongering media is ‘the rapidly melting Arctic’. Of course logic says that since glaciers can grow naturally they can also retreat naturally, despite attempts to blame humans.
European satellites have detailed the abrupt change in behaviour of one of Greenland’s most important glaciers, says BBC News.
In the 2000s, Jakobshavn Isbrae was the fastest flowing ice stream on the island, travelling at 17km a year.
As it sped to the ocean, its front end also retreated and thinned, dropping in height by as much as 20m year.
But now it’s all change. Jakobshavn is travelling…

Below is a plot from a resource we have not used before on WUWT, “RIMFROST“. It depicts the average temperatures for all weather stations in Antarctica. Note that there is some recent cooling in contrast to a steady warming since about 1959.
Contrast that with claims by Michael Mann, Eric Steig, and others who used statistical tricks to make Antarctica warm up. Fortunately, it wasn’t just falsified by climate skeptics, but rebutted in peer review too.

No warming has occurred on the South Pole from 1978 to 2019 according to satellite data (UAH V6). The linear trend is flat!
From Musings from the Chiefio:
Fourteen minutes well spent that shows how wrong the “Climate Models” are, and why that matters to all of us due to the EPA “Endangerment Finding” being based 100% on those broken models.
I find it interesting that The Russians have a climate model that works. Wonder if it is open sourced? If anyone knows, or knows how to get a copy, let me know! It would save a lot of time trying to make one that works from the crap that doesn’t…
From Scientific American:
A Guide to Volcanoes
Within three weeks of the Mt. Pinatubo eruption, the largest volcanic blast of the century, a band of sulfur aerosol had encircled the globe. By early 1992, the volcanic gases and aerosols had diffused through the stratosphere, veiling the earth. During that time, global carbon dioxide levels fell more sharply than any other decline on record. Some scientists suggested that global cooling caused ecosystem respiration to drop, lowering the amount of carbon dioxide emitted into the atmosphere. But Lianhong Gu of Oak Ridge National Laboratory, lead author of the Science report, didn’t think that could be the only explanation.
Gu knew that crop scientists had discovered that plants grow best in diffuse light. When sunlight is too intense, some leaves fall into shadow, unable to photosynthesize, while others bask in the direct beams but will reach a photosynthetic saturation point. Moderate cloud cover and aerosols block direct beams, but allow light to bounce back and forth off water vapor and other molecules, creating a “softer” light that reaches leaves that would otherwise be shaded. As a result, the plants photosynthesize more, using up carbon dioxide in the process. Gu and his collaborators determined that the same principles apply to forest canopies. The Harvard Forest data show that carbon dioxide levels dropped for two years following the eruption at Mt. Pinatubo findings that the scientists suggest represent a worldwide phenomenon given that the eruption had a global atmospheric effect. “Up until now we hadn’t linked aerosols and clouds with carbon studies,” Gu says. “In order to understand atmospheric carbon dioxide concentrations, which affect climate, we have to look at how aerosols and clouds affect the global carbon cycle.”
Geologist Gregory Whitestone provides a climate history lesson for warmists who skipped history classes protesting against global warming. Hist article at Town Hall is Ocasio-Cortez’s Climatology Lacks Historical Context. Excerpts in italics with my bolds. H/T Climate Depot.
When Sam Cooke sang “Don’t know much about history” in 1960 he could not have had U.S. Rep. Alexandria Ocasio-Cortez in mind, but only because she lives a half century later.
Whatever Ocasio-Cortez got from history classes during her time at Boston University, it wasn’t an appreciation of historical context because it is sorely lacking in her assertions about climate and its effect on humankind. She and others promoting the Green New Deal have the facts exactly backwardswhen they claim that warming temperatures are an existential threat to humanity.
Ocasio-Cortez recently warned in a House Oversight Committee hearing that the United States would have “blood on our hands” if legislation to…

Extreme scientists and politicians warn we will suffer catastrophic climate change if the earth’s average temperature rises 2.7°F above the Little Ice Age average. They claim we are in a climate crisis because average temperature has already warmed by 1.5°F since 1850 AD. Guided by climate fear, politicians fund whacky engineering schemes to shade the earth with mirrors or aerosols to lower temperatures. But the cooler Little Ice Age endured a much more disastrous climate.
The Little Ice Age coincides with the pre-industrial period. The Little Ice Age spanned a period from 1300 AD to 1850 AD, but the exact timing varies. It was a time of great droughts, retreating tree lines, and agricultural failures leading to massive global famines and rampant epidemics. Meanwhile advancing glaciers demolished European villages and farms and extensive sea ice blocked harbors and prevented trade.
Dr. Michael Mann who preaches dire predictions wrought by global warming described the Little Ice Age as a period of widespread “famine, disease, and increased child mortality in Europe during the 17th–19th century, probably related, at least in part, to colder temperatures and altered weather conditions.” In contrast to current models suggesting global warming will cause wild weather swings, Mann concluded “the Little Ice Age may have been more significant in terms of increased variability of the climate”. Indeed, historical documents from the Little Ice Age describe wild climate swings with extremely cold winters followed by very warm summers, and cold wet years followed by cold dry years.
A series of Little Ice Age droughts lasting several decades devastated Asia between the mid 1300s and 1400s. Resulting famines caused significant societal upheaval within India, China, Sri Lanka, and Cambodia. Bad weather resulted in the Great Famine of 1315-1317 which decimated Europe causing extreme levels of crime, disease, mass death, cannibalism and infanticide. The North American tree-ring data reveal megadroughts lasting several decades during the cool 1500s. The Victorian Great Drought from 1876 to 1878 brought great suffering across much of the tropics with India devastated the most. More than 30 million people are thought to have died at this time from famine worldwide.
The Little Ice Age droughts and famines forced great societal upheaval, and the resulting climate change refugees were forced to seek better lands. But those movements also spread horrendous epidemics. Wild climate swings brought cold and dry weather to central Asia. That forced the Mongols to search for better grazing. As they invaded new territories they spread the Bubonic plague which had devastated parts of Asia earlier. In the 1300s the Mongols passed the plague to Italian merchant ships who then brought it to Europe where it quickly killed one third of Europe’s population. European explorers looking for new trade routes brought smallpox to the Americas, causing small native tribes to go extinct and decimating 25% to 50% of larger tribes. Introduced diseases rapidly reduced Mexico’s population from 30 million to 3 million.
By the 1700s a new killer began to dominate – accidental hypothermia. When indoor temperatures fall below 48°F for prolonged periods, the human body struggles to keep warm, setting off a series of reactions that causes stress and can result in heart attacks. As recently as the 1960s in Great Britain, 20,000 elderly and malnourished people who lacked central heating died from accidental hypothermia. As people with poor heating faced bouts of extreme cold in the 1700s, accidental hypothermia was rampant.
What caused the tragic climate changes of the Little Ice Age? Some scientists suggest lower solar output associated with periods of fewer sunspots. Increasing solar output then reversed the cooling and warmed the 20th century world. As solar output is now falling to the lows of the Little Ice Age, a natural experiment is now in progress testing that solar theory. However other scientists suggest it was rising CO2 that delivered the world from the Little Ice Age.
Increasing CO2 also has a beneficial fertilization effect that is greening the earth. The 20th century warming, whether natural or driven by rising CO2 concentrations, has lengthened the growing season. Famines are being eliminated. Tree-lines stopped retreating and trees are now reclaiming territory lost over the past 500 years. So why is it that now we face a climate crisis?
At the end of the 1300’s Great Famine and the Bubonic Plague epidemic, the earth sustained 350 million people. With today’s advances in technology and milder growing conditions, record high crop yields are now feeding a human population that ballooned to over 7.6 billion.
So, the notion that cooler times represent the “good old days” and we are now in a warmer climate crisis seems truly absurd.
