RELATIVE WARMING
• Relative Warming Potentials include
the
GWP relationships + the gas emissions to indicate a relative environmental effect.
GWP relationships + the gas emissions to indicate a relative environmental effect.
• CO2 will result in
50% of the RWP over the
next 200 years hence the attention.

• Radiative
forcing is the quantitative change in the radiative flux at the tropopause ® altered radiative balance.
• The natural
perturbation of Mt Pinatupo (SO2 ® nss aerosol) caused a major change in radiative forcing
global -0.5oC (1992 - 3).
