Measuring any Differences in Infrared Absorption Between Dry Air, Humid Air and Dry Carbon Dioxide

This anisotropicplus video is a simple experiment using a common infrared heat lamp to measure any differences in infrared absorption between dry air, humid air and dry carbon dioxide. This was originally published two years ago, but due to some out of date charts showing the increase in CO2 levels with time I removed them, but left the link information for anyone interested. I have learned that you have to pay attention to the spectral output of your IR source and the absorption bands of the gas you are testing. You also have to consider that the atmosphere is many miles thick compared to a small lab scale container that can only absorb small amounts of the wavelengths involved. I highly recommend reading the CSSR, Climate Science Special Report, available at https://science2017.globalchange.gov/
