External forcing 

This refers.  It would be useful to explain this term better (I have a comment further up the talk page).  Does it refer to any process external to the climate?  Including thought processes?  Or to processes that have some effect on the climate.  Also it is highly confusing to have a section titled 'radiative forcing' when it begins with a (bad) definition of external forcing.  My point is a logical one only.  Also, do you agree with my comments on the GW talk page where I argue for more explanation of the reasons scientists believe in GW.  Also a better definition of GW. Is it (a) the fact that instrument temperatures are on average higher than a century ago (b) a process that underlies that fact (c) the hypothesis that the process has an anthropogenic cause?  These are all different things. (a) could be true because of random fluctuations (b) could be true if the process were a natural one.  Again, my points are only logical and definitional ones, I have no view on the science.
