13. The growth rate of forests depends on environmental factors like radiation (r), temperature (t), moisture (w) and on the other hand on investments done into forests (i) (including site preparation, planting, plant breeding and fertilization) The change in the tree biomass in forests can be presented as a spatial (s) and temporal (t) integral (∫) of these factors
t s
∫ ∫ (r, t, w, i)
0 0
In such calculations, if the time period looked at is short, the spatial area observed has to be large enough (preferably whole country) and if the spatial area looked at is small, the observation period needs to be long enough like (80 years), otherwise the calculation is not sensible.

14. To understand the logic of the carbon sinks of forests is challengin
The annual growth of Finnish forests was in 1970 c.a. 50 milj. m3/a. After that more than 10 billion E has been invested to several silvicultural operations and due to that Finnish forests grow now more than 100 milj. m3/a. When suggesting to store carbon in older forests the outcom is not an increased sink but the opposite e.g. due to the reduced interest to invest in the future forest growth.

15. The primary cause of climate change is the use of fossil fuels
By taking good care of forests the case of Finland serves as an example of the unexpected situation where the intensive use and good care of forests we have increased simultaneously the biomass use, growth and standing biomass.
