Abstract

A major contributor to climate change and global warming, atmospheric carbon dioxide (CO₂) is the most significant human greenhouse gas. The main target of this work is to determine the dynamics of CO₂ concentration in Benghazi city and to compare it with global atmospheric emission of CO₂duringspring season 2023. The result revealed the main average concentration of CO₂ recorded in March 415 ppm, in April 416 ppm and recorded in May 424 ppm. The May period recorded the highest value of CO₂ in Benghazi, an increase of about 7 to 8 ppm degrees from April and March. May period is usually the period in which each year the highest CO₂ levels are recorded because the plants will close their stomata to prevent water evaporation and reduce photosynthesis efficiency. At this time, human activities become more and more frequent, which eventually leads to an increase in the concentration of CO₂ in the atmosphere. Globally the CO₂ concentration in May 2022 was recorded 421 ppm by the Mauna Loa Observatory in Hawaii. In May 2023 was recorded 424 ppm, an increase of about 3 ppm degrees from last year, this increase caused the new rise in global warming caused by human activities
