Climate change threatens to triple global wheat prices

Climate change and increasing water scarcity are driving up global food costs, with significant implications for wheat markets. Research published in the journal Earth's Future indicates that if global temperatures rise by 2 degrees Celsius, the price per ton of wheat could reach approximately $273. A 3-degree increase could push prices to $364, which is triple the inflation-adjusted global wheat price from 2010.

Analysis of agricultural and market data from 2000 to 2021 shows that 74% of year-to-year fluctuations in wheat prices can be directly attributed to severe water shortages. While drought impacts are less pronounced for corn and less evident in rice, wheat remains highly vulnerable.

Beyond climate, other factors such as energy and fertilizer costs, stock levels, and geopolitical crises also influence markets. However, experts warn that simultaneous droughts across multiple major production regions could trigger a global food security crisis, making basic staples inaccessible to billions of people. Long-term shifts in climate may also redraw the global trade map as agricultural production zones migrate to more favorable climates.
