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. For example, wheat production in southern Europe has decreased by 10% over the past decade due to heat stress. However, in northern regions, longer growing seasons have actually boosted potato yields. But this benefit is not universal, as some areas face increased pest problems. Farmers in Scandinavia have reported a 15% rise in pest damage, which offsets the gains. Therefore, while some regions may see short-term benefits, the overall trend is negative, especially for staple crops like rice, which is highly sensitive to temperature changes.
