Today we're going to discuss the impact of climate change on agriculture. In particular, I want to focus on how rising temperatures affect crop yields. A recent study from the University of California found that for every degree Celsius increase, wheat production drops by about 6%. However, this effect is not uniform. In cooler regions, such as northern Europe, higher temperatures might actually extend the growing season, leading to increased yields. But in tropical areas, where crops are already near their heat tolerance, even a small rise can cause significant losses. The study also highlighted that adaptation strategies, like developing heat-resistant crop varieties, could mitigate some of these negative effects.
❓ Según la conferencia, ¿cuál es el impacto de un aumento de un grado Celsius en la temperatura sobre la producción de trigo?
A. A) Aumenta los rendimientos de trigo en un 6% en todas las regiones.
B. B) Disminuye los rendimientos del trigo en aproximadamente un 6% en promedio.
C. C) No tiene ningún efecto en la producción de trigo en las zonas tropicales.
D. D) Solo afecta la producción de trigo en el norte de Europa.
✅ 正确答案
B) It decreases wheat yields by about 6% on average.
