This posting sets out a preliminary understanding of the “carbon cycle” that you may not be aware of. The next posting will build off of this to lay out the science of climate change.
The Sun is the Earth’s source of energy. The energy is transported in the form of waves (radiant energy) known as electromagnetic energy. The Sun’s enormous surface temperatures generates these waves. The waves have a wide range of frequencies. In general, the waves are known familiarly as x rays, ultraviolet, sunlight, short wave infrared, radio waves, and microwaves. These waves heat the Earth. Not all of the waves get through to the Earth’s surface. Some are absorbed like Ultraviolet by ozone; some are reflected back into space by clouds; and some are scattered by encountering mater in the atmosphere.
Much of the Suns energy is reemitted from the Earth as longwave infrared. Some of the reemitted energy is delayed on its way back out into space by the so called greenhouse gases and water vapor. This slowdown is the reason the Earth has a habitable temperature. The primary greenhouse gas is carbon dioxide (CO2). However, water vapor is the largest factor, by far, in the greenhouse effect.
