Global Warming Could Slash Staple Crop Yields by 2100

A study published on 18^th June 2025 warns that rising global temperatures could significantly reduce the yields of major staple crops — including wheat, maize, rice, sorghum, and soybean — despite adaptive farming practices.

What did the study find?

• A 1°C rise in global temperature could reduce per capita calorie availability by 4% by 2100.
• Global yields for most major crops are projected to decline by 2050 and even more sharply by 2100.
• Wheat yield losses are especially severe in northern India and consistent across major regions — ranging from –15% to –40% under high-emissions scenarios.
• Rice yields in India and Southeast Asia ....
