Five Charts: The Influence of Climate Change on Global Food Prices

Recent years have witnessed significant fluctuations in global food prices, peaking in 2022 before stabilizing somewhat in 2023, only to start climbing again in 2024. Experts have attributed these price changes to a combination of extreme weather events, geopolitical conflicts, rising input costs, and increasing global demand. This article, originally published by Carbon Brief, explores the complex relationship between climate change and food prices through five key charts that offer a detailed analysis of the situation.

1. Europe: Heatwaves and Rising Food Inflation

A 2024 study highlighted the persistent impact of extreme heat on food inflation in both high- and low-income countries. By analyzing over 27,000 monthly consumer price indices from 121 countries between 1996 and 2021, the study found that higher temperatures, especially during already hot months, significantly increased food prices. The summer of 2022, which saw unprecedented heatwaves across Europe, exemplified this trend. Food inflation in Europe spiked by 0.43-0.93 percentage points due to the extreme temperatures, with some regions experiencing food inflation rates as high as 19%.

2. United Kingdom: Heavy Rainfall and Delayed Crop Planting

The UK has faced one of its wettest periods in recorded history from September 2022 to February 2024, with rainfall levels significantly above average. This excess rainfall led to waterlogged soils, delayed crop planting, and a subsequent decline in vegetable production by 4.9% in 2023. Crops like cauliflower and bulb onions saw substantial reductions in yield, affecting overall agricultural output. The ongoing wet conditions, coupled with severe weather events like Storm Babet, have made farming increasingly challenging in the UK.

3. United States: Declining Orange Production

The US, particularly Florida, has experienced a dramatic drop in orange production due to a combination of hurricanes and citrus greening disease. Hurricane Ian in 2022 devastated much of Florida’s citrus belt, leading to a more than 50% reduction in the state’s orange production between the 2021-22 and 2022-23 harvests. The increasing frequency of such extreme weather events, compounded by the spread of citrus greening disease, has driven up the price of orange juice in the US, nearly doubling it from 2020 to 2024.

4. Mediterranean: Olive Oil Production and Heat Stress

Olive oil production in Mediterranean countries, particularly Spain, Italy, and Greece, has been severely impacted by extreme heat and drought conditions. Between 2021 and 2024, global olive oil production declined by approximately one-third, leading to significant price increases. Spain, the world’s largest olive oil producer, saw a 28% rise in production from the previous year, but levels remained far below the five-year average. The extreme weather has not only reduced yields but also made olive oil one of the most expensive and frequently stolen items in supermarkets across Spain.

5. China: Weather Extremes and Rice Yield Reductions

China, the world’s largest producer of rice, wheat, and corn, has seen its rice yields drop by 8% from 1999 to 2012 due to extreme weather events. Recent years have brought even more challenges, with a combination of high temperatures, floods, and droughts causing significant damage to crops. July 2024 marked China’s hottest month on record, exacerbating the already difficult conditions for farmers. The resulting crop failures have led to higher prices for staple foods like cabbage, spinach, and pears, putting additional pressure on consumers.

Conclusion

These charts illustrate the profound impact that climate change is having on global food systems, from production to pricing. As extreme weather events become more frequent and severe, the volatility in food prices is likely to increase, posing challenges for both producers and consumers. Reducing greenhouse gas emissions and adapting agricultural practices are essential steps to mitigate these impacts and ensure food security in the future.

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression Dinotefuran is known to negatively affect honeybee ( Apis mellifera ) behavior, but the underlying mechanism remains unclear. The magnetoreceptor ( MagR , which responds to magnetic fields) and cryptochrome ( Cry2 , which is sensitive to light) genes are considered to play important roles in honey bees’ homing and localization behaviors. Our study found that dinotefuran, even without direct contact, can act like a magnet, significantly altering MagR expression in honeybees. This non-contact exposure reduced the bees’ homing rate. In further experiments, we exposed foragers to light and magnetic fields, the MagR gene responded to magnetic fields only in the presence of light, with Cry 2 playing a key switching role in the magnetic field receptor mechanism ( MagR–Cry2 ). Yeast two-hybrid and BiFc assays confirmed an interactio...

“Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns

“Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns The World Beekeeping Awards will not grant a prize for honey next year due to the “inability” to thoroughly test honey for adulteration. The announcement comes amid the rise of honey fraud in the EU, where a 2023 investigation found that 46% of 147 honey samples tested were likely contaminated with low-cost plant syrups. Apimondia, the International Federation of Beekeepers’ Associations, organizes the event at its Congress, whose 49th edition will be held in Copenhagen, Denmark, in September 2025. The conference brings together beekeepers, scientists and other stakeholders. “We will celebrate honey in many ways at the Congress, but honey will no longer be a category, and thus, there will be no honey judging in the World Beekeeping Awards. The lessons learned from Canada 2019 and Chile 2023 were that adequate testing was impossible if we are to award winning honey at the Con...

New Report – Interlocked: Midwives and the Climate Crisis

New Report – Interlocked: Midwives and the Climate Crisis Earlier this year, midwives from 41 countries shared their experiences of working in communities affected by climate change through our survey, Midwives’ Experiences and Perspectives on Climate Change. Their voices shaped our new report, Interlocked: Midwives and the Climate Crisis , which highlights how midwives are already responding to the health impacts of climate disasters like floods, wildfires, and extreme heat—and why they must be included in climate action plans. What did we learn?Climate change is damaging community health: 75% of midwives reported that climate change is harming the communities they serve, with rising rates of preterm births, food insecurity, and restricted access to care during disasters like floods. Midwives are critical first responders: Midwives are often the first and only healthcare providers on the ground in crises, delivering care during wildfires, floods, and extreme heat. Midwives face signi...

Start the New Year Humming Like a Bee

Start the New Year Humming Like a Bee There are lots of opportunities to be as busy as a bee during these winter holidays. As we hustle toward the dawn of the New Year, it can be hard to notice that the natural world is actually suggesting something different for us right now. We’re past the solstice, but the winter still stretches ahead, the days are still short and the nights long. We’re being invited into a quieter, more inner-focused time. The ancient yogis were all about this inner focus. In India, for example, the Upanishads, the Sanskrit writings that accompanied the development of Hinduism — and alongside it, yoga — beginning around 800 B.C.E., went deeper than earlier texts had into philosophy and questions of being. With the goals of increased inner awareness and higher consciousness, yoga was at that time not yet as focused on the body or on asanas, as it now can tend to be. But the yogis did develop many practices to try to open the way to those goals. They discovered...

The largest “killer hornets” in the world were exterminated in the US

The largest “killer hornets” in the world were exterminated in the US The US informed that it had exterminated the worldʼs largest hornets, nicknamed "killer hornets" — they are capable of occupying a hive of honey bees in just 90 minutes, decapitating all its inhabitants and feeding their offspring to their own. This was reported by the Department of Agriculture in Washington. The hornets, which can reach five centimeters in length, were previously called Asian giant hornets, but in 2019 they were also spotted in Washington state near the Canadian border. In China, these insects killed 42 people and seriously injured 1,675. A dead northern giant hornet (below) next to a native bald hornet. According to experts, the hornets could have entered North America in plant pots or shipping containers. The hornet can sting through most beekeeper suits because it produces nearly seven times more venom than a honeybee and stings multiple times. Thatʼs why the Washington Departme...

The Unexpected Surge: America's Honeybees Buzz Back to Record Numbers

The Unexpected Surge: America's Honeybees Buzz Back to Record Numbers In an age where environmental narratives often lean towards loss and decline, the story of the American honeybee offers a glimmer of hope and a puzzle to solve. Recent data from the Census of Agriculture reveals an astonishing rebound in the honeybee population, now soaring to an all-time high of 3.8 million colonies. This revelation comes as a surprise against the backdrop of two decades marked by fears of colony collapse and the potential ramifications for ecosystems and agriculture. The surge in bee populations brings to light a series of questions and insights into the intertwined worlds of agriculture, conservation, and legislation. Central to this narrative is the state of Texas, where legislative changes have catalyzed a beekeeping boom by offering agricultural tax breaks to landowners cultivating honeybees. This policy shift, coupled with the entrepreneurial spirit of Texans and the essential role of bees...
