What to know about Why apples react differently to climate change than wheat

Researchers from the Technical University of Munich analyzed 35 years of crop yield data in Germany, finding that wheat yields are declining due to rising temperatures while fruit trees currently benefit from reduced frost damage. The study emphasizes that pollinator-dependent crops will eventually face dual stress from climatic conditions and changes in pollinator populations, suggesting that biodiversity support is essential for long-term agricultural stability.

What happened

Why apples react differently to climate change than wheat Swati Mestri Scientific Editor Robert Egan Senior Editor Although climate change is already having a negative impact on crops, declines in yields have so far been offset by technological advances in…

Why it matters

For field crops that do not rely on pollinators, however, this trend appears to be reversing.

Common ground

Researchers at Technical University of Munich TUM analyzed crop yields in Lower Franconia and Upper Bavaria over more than 35 years.

Claim 1: “Researchers suspect they have so far benefited from rising temperatures, in part because there is less late-frost damage to their blossoms”
CORROBORATED
The study results indicate that fruit trees benefited from warming due to reduced late-frost damage to blossoms, a fact corroborated by the study reports and general knowledge of frost damage risks.
