Global Warming .....

Lot of discussions are going on in different media and forums for this Global Warming. Co2 is blamed for this global phenomena but could it be because of extra energy released by the earth crust it self, during earthquakes and movement of the crusts ? Since last 10 to 15 years very serious earthquakes have taken place at various places and if you have noticed it is happening on the Asiatic plate ranging from Japan to Pakistan and gulf countries. Even if Earth quake do not occur but when two gigantic plates are rubbing each other there is a tremendous frictional forces and amount of these this friction energy is converted into heat and released into atmosphere. Could this be the reason of global warming?

Any comments and your views ?
