Scorching Heat: Unraveling the Worsening Impact of Hot Temperatures on Food Inflation

Why hot temperatures make food inflation worse

The year 2022 has brought unprecedented heat waves across the globe, breaking temperature records and causing significant disruption in various regions. The consequences of these extreme temperatures go beyond the immediate discomfort, as they are having a profound impact on our food supply chain and contributing to worsening food inflation. This article examines the reasons why hot temperatures are exacerbating food inflation and explores the implications for global food security.

The Heatwave Phenomenon

Throughout the summer of 2022, countries around the world experienced scorching heat waves that exceeded historical norms. From Coningsby, England, to China, Japan, India, and Pakistan, soaring temperatures posed immense challenges to people and the environment. Heat records were broken, wildfires ravaged landscapes, and people sought refuge from the sweltering conditions. These extreme weather events are no longer isolated incidents, but rather recurring phenomena, as highlighted by the UN’s Intergovernmental Panel on Climate Change (IPCC).

Weather and food supply linkages

Our food supply is inextricably linked to weather patterns, as most of our food is either grown or raised. When heat waves and other extreme weather events occur, they put significant stress on the food supply chain. The consequences of record-breaking temperatures are far-reaching, with immediate and long-term effects on agriculture, crop yields and livestock.

Impact on crop yields

The scorching temperatures of the summer of 2022 have already begun to affect crop yields in various regions. Japan’s meteorological agency has raised concerns about corn and soybean yields, signaling potential reductions in production. India, which experienced a devastating heat wave, suspended wheat exports, further straining grain supplies already affected by geopolitical tensions. Similarly, Russia’s actions against Ukraine have disrupted grain supplies, contributing to the vulnerability of global food markets. These crop disruptions translate directly into higher prices for consumers as reduced supply leads to increased demand and inflation.

Consequences for livestock

Livestock also bear the brunt of extreme heat waves. The Kansas heat wave, for example, resulted in the death of more than 2,000 cattle due to heat stress. Intense heat can affect animal health, reduce forage availability and affect breeding patterns. These challenges, coupled with rising feed and forage costs, put additional pressure on livestock producers, who may pass the increased costs on to consumers.

The Rise of “Heatflation

The combined effects of extreme temperatures on crop yields, livestock and global food markets have given rise to a new term: “heatflation.” Agricultural experts are already anticipating the long-term impact of heat waves on food prices. However, the full extent of the phenomenon may not be felt for four to six months after the heatwaves as the effects ripple through the food supply chain. Tim Benton, Director of Environment and Society at Chatham House, stresses that any crop loss in a disrupted market will exacerbate price volatility as global demand outstrips supply.

Tackling the food inflation crisis

The combined factors of climate change, geopolitical tensions and the ongoing COVID-19 pandemic have brought the world to a critical juncture in terms of food security. Mitigating the impact of high temperatures on food inflation will require concerted efforts at multiple levels:

  1. Climate change mitigation: Governments, businesses and individuals must prioritize actions to mitigate climate change and reduce greenhouse gas emissions. Transitioning to sustainable agricultural practices, investing in renewable energy, and adopting climate-resilient crop varieties are critical steps to securing the future of our food supply.
  2. Enhancing resilience and adaptation: Increasing the resilience of agricultural systems to withstand extreme weather events is essential. This includes implementing irrigation systems, improving water management and developing climate-smart farming techniques. In addition, investment in research and innovation can lead to the development of heat-tolerant crop varieties and livestock breeds.
  3. International collaboration: The global nature of the food supply chain requires international cooperation and collaboration. Sharing knowledge, expertise and resources can help countries better respond to food crises and ensure an equitable distribution of resources.
  4. Consumer education: Educating consumers about the impact of extreme temperatures on food production and inflation can foster a greater appreciation for the value of food. Promoting sustainable consumption patterns, reducing food waste, and supporting local and regenerative agriculture can contribute to a more resilient and sustainable food system.


Rising temperatures and heat waves around the world are having a profound impact on our food supply chain, exacerbating the problem of food inflation. The interconnectedness of weather patterns, crop yields, livestock and global markets underscores the urgency of addressing the challenges posed by climate change. By prioritizing climate action, building resilience, fostering international cooperation, and educating consumers, we can begin to mitigate the impact of high temperatures on food inflation. Taking proactive action now is critical to ensuring a safe and sustainable food future for generations to come. By recognizing the link between extreme temperatures and food inflation, we can work towards building a more resilient and adaptive food system that can withstand the challenges of a changing climate.


How do high temperatures contribute to food inflation?

Hot temperatures can reduce crop yields, stress livestock, and disrupt the global food supply chain. These factors lead to reduced food availability and increased demand, driving up prices and exacerbating food inflation.

Which regions have been most affected by recent heat waves?

Recent heatwaves have affected different regions of the world. Notable examples include Coningsby in England, China, Japan, India and Pakistan, where record-breaking temperatures and heat-related challenges have been observed.

How will crop yields be affected by extreme temperatures?

Extreme temperatures can have a negative impact on crop yields. Heat waves can damage crops, reduce pollination, increase evaporation rates and lead to drought conditions. These factors lead to smaller harvests and reduced supply, contributing to food inflation.

What are the effects of high temperatures on livestock?

Livestock face increased heat stress during high temperatures, which can adversely affect their health, productivity, and reproductive behavior. Heat waves can also lead to reduced availability of feed and forage, further burdening livestock producers and potentially leading to higher meat and dairy prices.

How long will the impact of heatwaves on food prices last?

The full impact of heat waves on food prices may not be immediately apparent. It typically takes four to six months for the effects to work their way through the food supply chain and be reflected in higher prices. This delay is due to factors such as storage, transportation and market dynamics.

What can be done to address the issue of food inflation exacerbated by high temperatures?

Tackling food inflation requires a multifaceted approach. This includes implementing climate change mitigation strategies, building agricultural resilience to extreme weather events, promoting international cooperation, and educating consumers about sustainable consumption. These measures can help mitigate the impact of high temperatures on food inflation and build a more sustainable and secure food system.
