Olive Oil Prices Are Falling—So Should Olive Oil Climate Hysteria

Climate alarmists jump to hasty conclusions, then fail to correct the record.

Summary: Olive oil prices spiked in 2023 amid heat and drought in Spain, prompting widespread claims that climate change was driving the industry into crisis. Production has since rebounded and prices have fallen sharply, undercutting the hysteria, but no corrections have been issued. The episode illustrates how short-term agricultural disruptions are sometimes unreasonably framed as evidence of long-term climate catastrophe.


It’s the follow-up story that never gets written. An agricultural commodity experiences a period of below-average yields and rising prices, and it is reported as a climate change–induced crisis. Then, after another year or two, the trend reverses, but there are few, if any, attempts to correct the record.

Olive oil prices are a recent example. Spain, the world’s largest producer of olives for oil, experienced severe heat and drought in the summers of 2022 and 2023, contributing to much lower yields and major price spikes in 2023 and into 2024.

There were several news accounts at the time warning about a new reality in which human-induced warming would decimate olive yields. An August 2023 CNN story entitled “Olive Oil is in Trouble as Extreme Heat and Drought Push the Industry Into Crisis” was typical. Citing scientists and industry experts, the article told us that the episode “would have been virtually impossible without climate change.”

The story, and others like it, painted a bleak future for those making their living from olives and a new normal of higher olive oil prices for consumers. Beyond olives, CNN informed readers that “Experts warn of worse to come for food production, as the human-caused climate crisis increases the frequency and severity of extreme weather.”

However, toward the end of 2024, olive oil prices began falling sharply and remain well below their peak, according to the Federal Reserve Bank of St. Louis. The two most recent crops in Spain and other olive-growing nations have yielded enough to increase olive oil production substantially. Overall, the olive oil industry appears to be most of the way back to normal—hardly a crisis.

That should have surprised no one, especially the self-described experts relied upon in the gloomy coverage. Yields for olives, as with virtually every other agricultural commodity, have experienced year-to-year fluctuations throughout recorded history. While climate change’s influence on olives is entirely possible, an off year or two proves nothing. Over the longer term, overall yields for food crops have increased severalfold, especially in recent decades, when climate change was supposedly a headwind. Improved agricultural methods—which depend on fossil fuels for energy and fertilizer—have swamped any adverse climate impacts, if such impacts exist.

It is also worth noting the substantial scientific evidence that the release of carbon dioxide, blamed for contributing to climate change, has benefits for plant growth and may well be a net positive for agriculture. This may also help explain why agricultural bad news rarely has staying power while long-term trends remain positive.

In any event, the media outlets that raised the olive oil alarms ought to publish follow-up stories reporting the good news and conceding that the climate change link is not nearly as clear-cut as the original coverage suggested. None have done so.

Maybe it’s because they are too busy writing about the chocolate crisis.

Norway’s Automated Farm Sends Lettuce to Stores

“Norway's first fully automated facility for vegetable production was put into operation last fall. This spring, the first products hit store shelves…

'In this facility, no one touches the lettuce from the time it is sown, grown and packaged until it ends up on the store shelf and is finally opened by the customer at home in their kitchen,' says SINTEF researcher Ottar Bakås.”

US Irrigation Avoids More Emissions Than It Emits

“Irrigating U.S. crops prevents higher greenhouse gas emissions by avoiding land conversion, new research by Colorado State University shows. Agricultural irrigation allows the United States to grow more food on less land. If irrigation were suddenly shut off, the land-use change required to make up for lost yields would produce significantly more greenhouse gas emissions than irrigation emits—363 times more.

CSU scientists estimate the emissions saved by avoiding land-use change would equate to 363 years' worth of today's U.S. annual greenhouse gas emissions from irrigation.

Converting natural ecosystems to agricultural use releases carbon stored in soil and vegetation. Land use and land conversion for agriculture to produce food, fiber and fuel contribute nearly a quarter of global greenhouse gas emissions, making the sector a key priority for emissions reductions, the study published in Proceedings of the National Academy of Sciences states.”

More Can Tho Rice Farmers Adopt Mechanized Seeding

“When the Fertilize Right (FerRight) project began working with rice farmers in Can Tho's Thanh An, Thanh Phu, Thoi Xuan, and Trung Hung communes, mechanized direct seeded rice (mDSR) was practiced by fewer than 1 in 100 of them. Two years later, the project's midline farmer survey found that 18% of farmers in these communes had adopted the technology — up from a 2023 baseline of just 0.7%. Fertilizer deep placement, a complementary practice often paired with mDSR, has also taken hold, now reaching 0.5% of farmers and growing. Together, the numbers are one of the clearest signals yet that the project, funded by the United States Department of Agriculture (USDA) and implemented by the International Rice Research Institute (IRRI), is changing how farmers cultivate their rice.

Unlike traditional broadcast seeding, mDSR, paired with fertilizer deep placement, uses dynamic, air-assisted row seeders to place seed precisely 1 to 2 mm into the soil and deliver nutrients directly to the root zone. Multi-season field trials with the Cuu Long Rice Research Institute (CLRRI), spanning four crops from 2024 to 2026, show why the technology is catching on: seed rates fall by at least 50%, nitrogen fertilizer use drops by at least 20%, and the carbon footprint per kilogram of rice produced falls by at least 10%, alongside more uniform stands and greater resilience to pests, disease, and lodging.

Those gains show up in farmers' fields, too. Comparing mDSR adopters with farmers who still broadcast-seed, the project's farm-level adoption study found mDSR fields yielded 6.81 tons per hectare against 6.67 tons for broadcast seeding — a 2.1% advantage — with nitrogen-use efficiency up 1.4% and net income up 2.7% per hectare.”

Autonomous Crop Dusters Commercially Approved in US and Brazil

“Self-flying planes have been slower to emerge than self-driving cars, despite operating in what is generally considered a more structured and predictable environment.

That is partly because big tech companies 'doubled down' on cars, pouring vast sums into the technology, says Mykel Kochenderfer, an expert in safe aviation autonomy at Stanford University.

But it is also because aircraft are held to stricter safety standards than cars, creating a much higher bar for deployment…

In the US, the largest autonomous fixed-wing aircraft approved for commercial civilian use so far is Pyka's crop sprayer, which won authorization last year.

Though operations are limited to a tightly defined agricultural setting and require a ground operator and visual observer. It earlier secured similar approval in Brazil, where rules are more permissive…

Supporters say autonomous aircraft could address pilot shortages, remove people from dangerous work such as crop spraying, improve efficiency – for example, by allowing aircraft to carry more cargo – and cut costs if one operator can oversee many planes.

They also argue automation could make flying safer, pointing to past declines in accidents as more automated systems have been introduced.”
