The Impact of Climate Change on Global Agriculture
Climate change poses significant threats to global food security by altering agricultural productivity and crop yields.
Key Findings
- Rising temperatures reduce wheat and maize yields in temperate regions.
- Increased frequency of extreme weather events disrupts planting cycles.
- Shifts in precipitation patterns affect water availability for irrigation.

| Region | Average Yield Change (%) |
|---|
| North America | -5.2 |
| Europe | -3.8 |
| Asia | +2.1 |
