Not all waves of the electromagnetic spectrum are blocked by Earth’s atmosphere. For example, both infrared and visible light easily penetrate and strike the surface of our planet. Infrared radiation is felt as heat rather than seen. Visible light that is reflected is seen, but that which is absorbed is converted to heat via quantum mechanics — which is then slowly radiated away as infrared radiation (IR).

IR, though not optically visible to the human eye, is detectable by ‘thermographic cameras’.

As IR passes thru the atmosphere, it does not interact with the lighter gases such as nitrogen and oxygen — however, heavier gases, such as water vapor and carbon dioxide, do interact with IR which slows it down. This causes an increase of infrared radiation (heat) in the atmosphere. This ‘blanketing effect’ is inaccurately known as the ‘greenhouse effect’.
