The three indices were run in the following sequence: (1) base index, (2) base index + climate change, and (3) base index + climate change + natural fire regime modifications.
In the publication by Kirschbaum and Wirth, an index of climate change, the climate index 'KI', was introduced[11].
Another single index of climate change is the Atmospheric Circulation Index (ACI) that characterizes the periods of relative dominance of either "zonal" or "meridional" transport of the air masses on the hemispheric scale.
Scientists contacted by the Nature Index listed climate change and its impact (particularly on ecology and corresponding carbon circulation), the mechanism of environmental pollution, geological changes, and oceanology studies as the most significant and productive areas of research in recent years.
In the index considering climate change, peat accumulation rate (hence SOL thickness) was allowed to vary according to an adaptation of the Peat Accumulation Model (PAM; Hilbert et al. 2000) made by Wu (2012).

Bowler, D. & Böhning-Gaese, K. Improving the community-temperature index as a climate change indicator.
In the base index (i.e. the index not considering climate change or fire), SOL thickness increased with time, following peat accumulation rates determined by Lecomte et al. (2006) for nearby sites located in the Clay Belt of Quebec.

Almost all respondents indicated that the livestock population had been decreasing from time to time due to feed shortage (ranking index = 0.38), followed by lack of water (ranking index = 0.32), and climate change (ranking index = 0.30).
Finally, in the index considering both climate change and natural fire regime, we first projected forest paludification considering the current fire cycle of 400 years as determined by Bergeron et al. (2004).
