Trying to decide about global warming

February 26, 2012

The facts about global warming are as follows:

  • Carbon dioxide, methane and other greenhouse gasses have the chemical property of being transparent to visible light, but translucent to infrared radiation (radiant heat).  The higher the concentration of these greenhouse gasses in the atmosphere, the more of the earth’s heat will be reflected back into their earth.
  • Concentrations of greenhouse gasses are rising steadily.  So are recorded temperatures.  There are other things that are known to affect global temperatures, but they all are cyclical.  The greenhouse effect will increase without limit, unless either human beings decide to set a limit or a crash in the global economic or ecological system sets a limit for us.
