===Inherent variability of climate===
Spontaneous fluctuations in global climate might explain the past variability. It is very difficult to know what the true level of variability from internal causes might be given the existence of other forces, as noted above, whose magnitude may not be known. One approach to evaluating internal variability is the use of long integrations of coupled ocean-atmosphere [[global climate model]]s. They have the advantage that the external forcing is known to be zero, but the disadvantage is that they may not fully reflect reality. The variations may result from [[chaos theory|chaos]]-driven changes in the oceans, the atmosphere, or interactions between the two.<ref name="melissa">{{cite journal |last1=Free |first1=Melissa |last2=Robock |first2=Alan |year=1999 |title=Global warming in the context of the Little Ice Age |journal=[[Journal of Geophysical Research]] |volume=104 |issue=D16 |pages=19,057 |bibcode=1999JGR...10419057F |doi=10.1029/1999JD900233 |doi-access=free}}</ref> Two studies have concluded that the demonstrated inherent variability was not great enough to account for the Little Ice Age.<ref name=melissa/><ref name="B2006">{{cite journal |last1=Hunt |first1=B.
