December  UTC   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
