Infrared Radiation & Blackbody

Thanks for your Qi reference. Fascinating healing waves! Recently I was searching for the definitions of radiant and reflected energy and ended up reading about a desert lizard and infrared.
Here are answers.com definitions that need to be read with right brain as well as left.
Infrared radiation
Electromagnetic radiation in which wavelengths lie in the range from about 1 micrometer to 1 millimeter. This radiation therefore has wavelengths just a little longer than those of visible light and cannot be seen with the unaided eye. The radiation was discovered in 1800 by William Herschel.
An infrared source can be described by the spectral distribution of power emitted by an ideal body (a blackbody curve). This distribution is characteristic of the temperature of the body. A real body is related to it by a radiation efficiency factor or emissivity which is the ratio at every wavelength of the emission of a real body to that of a blackbody under identical conditions. See also Emissivity.
Blackbody
An ideal energy radiator, which at any specified temperature emits in each part of the electromagnetic spectrum the maximum energy obtainable per unit time from any radiator due to its temperature alone. A blackbody also absorbs all the energy which falls upon it. The radiation properties of real radiators are limited by two extreme cases—a radiator which reflects all incident radiation, and a radiator which absorbs all incident radiation. Neither case is completely realized in nature. Carbon and soot are examples of radiators which, for practical purposes, absorb all radiation. Both appear black to the eye at room temperature, hence the name blackbody. Often a blackbody is also referred to as a total absorber. See also Heat radiation.
How do these energetics relate to our current events? Is the earth heating up because more humans are radiant radiators? Are systems crashing because more light is filtering through and what once fit no longer does so? Are we evolving in Qi as we watch an empire collapse?
