CO2 is a gas that has a significant effect on the climate. The relationship between CO2 and temperature increases is often called into question. The goal of the experiment described below is to illustrate the effect of a heightened CO2 concentration in the atmosphere.
To do so, air will be warmed in two open-topped containers, upon which two strong lights are pointed. The changes in the air temperature are documented over the course of the experiment. The air in one container is enriched with CO2 and differs from the other container only in its considerably higher concentration of CO2 in the container’s air.
After just a few minutes the container, in which the air has a higher CO2 content, shows a significantly higher temperature. As the basic conditions for the both atmospheres are the same and differ only in the CO2 content, the temperature difference must be an effect of the heightened radiation absorption of CO2.
Increasing the CO2 content is accomplished by simply dissolving several effervescent tablets containing high levels of CO2.
CO2 should be understood as an absorbtive gas that has a significant effect on climate.
