No, continuously changing properties exist for many features including 
for example the transit from wood to grassland but climate zones in 
addition have the problem of only being defined in the long term 
average.  You will be able to determine the density of trees growing in 
some area at any single point of time without much effort and can use 
this as a basis to verifiably decide if this is a wood or not.  But you 
will need to measure the temperature for many years to approximately 
determine the long term average.  Precipitation is even trickier.
