Main Body
② Evaporation from Insolation (oceans/water bodies) 71%
③ Convection via heating mechanisms and Areal distribution.
④ Turbulence due to dynamic Terrestrial heating.
⑤ Absorption by higher clouds (Cirrus) (Infrared) then Re-emission.
⑥ Reflection & Refraction from Stratosphere.
Conclusion
The earth as whole body tries to maintain its balance & its own Responsibility to help us same cause.
