As a result, increased productivity of some crops due to higher temperatures, longer growing seasons, and elevated CO2 concentrations could be offset by increased freeze damage.20 Heat waves during pollination of field crops such as corn and soybean also reduce yields (Figure 18.3).4 Wetter springs may reduce crop yields and profits, 21 especially if growers are forced to switch to late - planted, shorter - season varietie
