What Moray is trying to say is, that weather is a part of climate, and they are not equal. I'll have to prove this using math...
let weather=w
let climate=c
w does not equal c
w=c/x
in which x=a certain number far less than c
wx=c
Note that weather is the meteorological occurences over a period of time (for this, 5 years)
Climate is the average of weather over the long-term (for this 50 years)
So with this given data...
w=5
c=50
wx=c
x=10
So you can see, that a number of "weathers" (not a word, but I have to use it like this) make up one "climate". This means that they are describing the same thing, but weather is more variable than climate. This means that weather is harder to use as evidence for or against AGW.
I think that this cleared up that little struggle.
