The purpose of this study is to determine the impact of climate change(maximum and minimum temperature, relative humidity and precipitation) on the productivity of some crops in Egypt. The results of the multivariate regression model of the impact of climate change on wheat yield from(2005 – 2022)showed that for every unit increase in the average maximum and minimum temperature and precipitation, wheat yield increased by 0.016, 0.036 and 0.066 tons/acre, respectively, which are about 0.59%, 1.32% and 2.42% of the average wheat yield of about 2.73 tons/acre. On the other hand, for every unit increase in the average humidity, the average wheat yield will decrease significantly by about 0.004 tons/acre, which is about 0.15% of the average wheat yield.The increase in average maximum temperature and average humidity led to an increase in rice yield of 0.102 tons/acre and 0.009 tons/acre, respectively, which are 2.87% and 0.25% of the average rice yield of about 3.55 tons/acre. In contrast, the increase in average minimum temperature led to a decrease in average rice productivity of 0.008 tons/acre, which is equivalent to 0.23% of the average rice productivity. The study found that the increase in average minimum temperature led to an increase in potato yield of 0.159 tons/acre, which is equivalent to 1.40% of the average potato yield (about 11.37 tons/acre). For every unit increase in average maximum temperature and average humidity, the average potato yield decreased by 0.051 tons/acre and 0.089 tons/acre, respectively, accounting for 0.45% and 0.78% of the average potato yield, respectively.
