It may seem paradoxical that there is a negative correlation between yield loss and the number of spring frost events for crops such as corn, soybean, and winter wheat (as shown in Figure 1). However, this can be explained by the fact that as the number of spring frost events decreases, the probability of crop damage also decreases. Furthermore, studies have shown that global warming can lead to an increase in daily minimum temperatures, which can reduce the damage caused by spring frosts and ultimately benefit crop yields.

However, it is important to note that even with rising global temperatures, the risk of yield loss due to spring frosts has also increased (as indicated in Figure 1). This suggests that simply analyzing the number of spring frost events may not accurately reflect the cumulative damage caused by these events on crops
