The factors that contribute to warming are those that promote the retaining of heat of the sun within the earth's atmosphere through greenhouse effect, while those that contribute to cooling are those that boost the dissipation of heat away from the earth. See attached table:-
There are many factors that influence the climatic conditions. The climate changes due to internal reasons as well as external factors. The most important factor is solar radiations. The greenhouses gases cause a Warming effect on earth's surface. The most important greenhouse gases are water vapour and carbon dioxide.
