The video describes the phenomenon called Greenhouse Effect. The glass house in the video is a prototype of our atmosphere. The house receives light of different frequencies from the sun. Radiations absorbed by the objects within the glass house are radiated back to the air. As a result heat radiations are trapped within the glass house. This eventually increases the temperature inside the glass house. This kind of house is also called 'green house' and hence 'greenhouse effect'. Similar phenomenon is observed in our atmosphere. Infrared radiations radiated back from the ground to the atmosphere are trapped by molecules like carbon dioxide, nitrogen dioxide, water vapor etc. Thus, our atmospheric temperature rises. Carbon dioxide from the exhaust gases of cars, factories, etc. contributes a lot to the rise in greenhouse effect.
