Abstract: 

This study aims to study the current state of temperature at Damascus station and the changes that occurred and the correlation with carbon dioxide concentration. Carbon dioxide (CO2) in the Atmosphere near Earth surface has increased significantly and has been very significant over time, with a correlation coefficient greater than 0.99. There has been a clear and significant increase in the average annual temperature and the average monthly temperature in April through October, and the biggest rise has been in summer months (June, July, and August), there has been a significant correlation between the average temperature and carbon dioxide concentration (R = 0.86). High temperature in Damascus is due to the increase in the average of annual minimum temperature, mainly the increase in the average monthly minimum temperature in summer months. The correlation coefficient between average annual minimum temperature and time was significant (R = 0.895), in addition its relationship with carbon dioxide concentration has been very significant (R = 0.84). There has been also a rise in the average of maximum temperature, but at a lower rate than in the average of minimum temperature, the correlation coefficient with time (R = 0.7) and the correlation coefficient with carbon dioxide (R = 0.7).
