Introduction

Light from the Sun coming to Earth passes through a blanket of thermal, or greenhouse, gases unhindered.

As the light comes in contact with the Earth’s Surface, “Infrared radiation”, unseen by the naked eye , differentiates it from visible light, is reflected of the planet’s surface towards space but does not pass easily through the thermal blanket.

Some of it is trapped and in return, is reflected downward keeping the planet at an average temperature suitable for maintaining life, which is 16°C (60°F).
