A humble suggestion, to ask first what is the meaning of climate, and if defined as ‚average weather‘, whether „weather“ is defined in a useful manner. Read for example:

Letter to the Editor, NATURE 1992, “Climate Change”, Vol. 360, p. 292; http://www.whatisclimate.com/1992-nature.html

and more recently: “Climate is a big issue, but science cannot say what it is!”
