The increasing prevalence of
greenhouse gases in the atmosphere due to human activities and microbes has
intensified the absorption of thermal radiation, exclusively known as the
greenhouse gas effect. In other words,
the higher levels of carbon dioxide, methane, nitrous oxide, water vapor, ozone,
hydrofluorocarbons (HFCs), perfluorinated chemicals (PFCs), and sulfur
hexafluoride (SF6) in the atmosphere are reradiating solar energy to
the lower atmosphere and surface of Earth, entrapping an elevated quantity of heat. The retention of heat is thought to be the
cause of rising atmospheric and ocean temperatures, which have led to concerns
of global warming. Below I have included
a detailed illustration of the greenhouse gas effect to enhance understanding
of the greenhouse effect.
Also, indicated below is the percentage contribution to the
greenhouse effect of the more significant greenhouse gases:
- Water vapor, 36-70%
- Carbon dioxide, 9-26%
- Methane, 4-9%
- Ozone, 3-7%
