2. Global warming
(Principle)
Due to the results of human activities such as a large
quantity of consumption of petrochemical fuels (e.g.
petroleum, coal, and natural gas) and forest
destruction, carbon dioxide, chlorofluorocarbon,
methane, and others in the atmosphere have been
increasing beyond the limit that natural force can
remove them.
As a result, the dissipation of heat from Earth's surface
is interrupted (greenhouse effect), thus resulting in
global warming.
Carbon dioxide, fluorocarbon, methane, nitride,
and others are released from Earth's surface.
Solar light beam

absorb the infrared rays.
Infrared rays

Earth
Infrared rays (heat rays) from Earth's surface are
absorbed.
Heat (temperature) cannot be dissipated from
Earth's surface.
Resulting in temperature rise and sea level rise.
