Global Warming Linked to Decline in Spring Frosts but Increase in Crop Yield Losses

With the rise in global temperature anomaly (Fig1.A), there appears to be a consistent decrease in the number of spring frost events (Fig1.B). Linear regression analysis shows a strong negative correlation between the two (Fig1.C), indicating that global warming is causing a decrease in spring frost events. However, despite fewer frost events, the loss of yield for crops such as corn, soybean, and winter wheat has been increasing over the years (Fig1.D, E, F). This suggests that other factors related to climate change, such as changes in precipitation patterns or increased pest pressure, may be contributing to the decline in crop yields.
