In today's lecture, we'll discuss the impact of climate change on agriculture. Specifically, I want to focus on how rising temperatures affect crop yields. According to a recent study, wheat production could decrease by 6% for every degree Celsius increase in global temperature. However, this impact varies by region. For example, in northern Europe, some crops might actually benefit from warmer conditions, but in southern regions, water scarcity becomes a major issue. The study also highlights that adaptation strategies, such as developing drought-resistant seeds, could mitigate these effects, but only if implemented early.
❓ What does the lecturer say about the impact of rising temperatures on wheat production?
A. It will increase by 6% for each degree of warming.
B. It will decrease by 6% for each degree of warming.
C. It will remain unchanged in all regions.
D. It will only affect southern Europe.
✅ 正确答案
It will decrease by 6% for each degree of warming.
