How Climate Change Is Impacting Your Grocery Bill and What You Can Do About It

If you’ve noticed a jump in prices for everyday items like onions, potatoes, or even your morning tea, you’re not alone. Recent research shows that climate change is significantly affecting food prices worldwide, including in India.

A study led by Maximilian Kotz from the Barcelona Supercomputing Center reveals that extreme weather—like heatwaves and floods—has hit food production hard. Between 2022 and 2024, these weather events damaged crops in at least 18 different countries, pushing prices higher.

“Until we reach net-zero emissions, extreme weather will worsen,” Kotz notes. “It’s already harming crops and raising food costs globally.”

India’s Heatwave: A Case Study

In May 2024, a severe heatwave struck parts of India, raising temperatures by 1.5°C. The impact was immediate: prices for onions and potatoes soared over 80%. These staples are crucial for many households, and such price hikes hit poorer families the hardest.

“When basic foods become too expensive, people’s daily meals are affected,” says Dr. Kavita Sharma, a public health expert in Delhi.

A Global Issue

The trend isn’t limited to India. Countries like South Korea, Brazil, and the UK have seen similar spikes in food prices due to climate-related events. For instance:

• In South Korea, cabbage prices increased by 70% after an exceptionally hot summer.
• Japan faced a 48% rise in rice prices after the August 2024 heatwave.
• Brazil’s coffee prices surged 55% following a drought in 2023.
• In Ghana and Ivory Coast, cocoa prices skyrocketed by 280% due to extreme heat.

The effects are stark in Australia as well, where floods caused lettuce prices to jump by 300%. Such climate events pose significant risks, with experts stating that the drought in Ethiopia was “100 times more likely” due to climate change, leading to a 40% rise in food prices.

In the UK, potato prices rose by 22% in just a month due to heavy rainfall, directly linked to climate change impacts. As Amber Sawyer from the Energy and Climate Intelligence Unit points out, “Climate change added £360 to the average U.K. household food bill across 2022 and 2023.”

Health and Nutrition Consequences

Rising food costs can have serious health implications. Nutritious foods are already twice as expensive as less healthy options. When prices go up, low-income families may cut back on fruits and vegetables, worsening malnutrition among children and increasing health risks for adults.

Dr. Sharma emphasizes the mental health toll as well. “Food insecurity can lead to stress and anxiety, affecting families in deep ways.”

The Situation in South Asia and Beyond

India already faces challenges like hunger and health disparities. Rising food prices only exacerbate these issues. “We’re up against a climate crisis and public health emergency simultaneously,” says Raj Patel, a research professor at the University of Texas. He warns that rising food prices have historically sparked social unrest in various countries.

While governments have agreed to limit emissions, current targets may fall short of what’s needed to meet global warming goals set in the Paris Agreement.

In light of these challenges, the recent UN Food Systems Summit aimed to address the climate-related threats to global food security. Experts are urging that food security be treated as a climate issue going forward. Kotz offers a sobering reminder: “These impacts will land right on your plate.”

Recent surveys indicate that many people now consider rising food prices the second most visible effect of climate change in their daily lives, right after extreme heat. The consequences of climate change are no longer distant threats—they’re affecting what we eat and how much we pay right now.

As we face these interconnected challenges, the pressing question becomes not just how climate change influences food prices, but what actions we are ready to take. If farmers struggle to grow our food, the costs won’t only be financial; they’ll impact health, stability, and lives.
