Lots of people discuss 'climate change' but what does the word 'climate' mean?
Folks forget how climate is defined.....
Climate is normally defined as 'an average over 3 conventional decades'.
A conventional decade is, for example, 2001-2010, or 1961-1970.
So ..... 3 full, conventional decades......such as 1981 to 2010.
For example .... rainfall in Ireland.
And another example - 'Average temperature 1951-1980'
The definition of 'climate' goes back at least 100 years.
So if we are discussing climate change, that is what 'climate' means.
But in recent times, there has been a lot of variation in global temperatures.
So it can be useful to look at single conventional decades.
