Climate change is an extremely important issue for global society, and a special topic for natural sciences. This subject is frequently presented by communication media and discussed in different sectors of the population. This article shows the exploration of the conceptions regarding CO2 and its influence on climate change, in a group of university General Chemistry students. A Likert-type test was used as instrument for initial exploration (pretest) and final assessment (posttest), intercalated by a didactic intervention based on experimental activities with a kit for generating, collecting, and identification of CO2. These experimental activities were accompanied with a subsequent discussion about specialized (bibliographic and audiovisual) study material. Results showed the existence of misconceptions, scarce scientific knowledge on the climatic phenomenon, and a strong trend for thinking that carbon dioxide is the main factor in the climate change problems. Furthermore, student responses revealed the tendency to believe that the human being is almost the unique element responsible of such phenomenon. The didactic intervention was favorable and motivating to remove the misconceptions and build a scientifically more structured knowledge. The present work allows advancing on the construction of a (scientific) climate educational proposal for helping the society and involving the people in the solving of environmental problems.
