Abstract
Climate change may affect the behavior of various systems on earth, one of which is human population. In the current literature, it is hypothesized that anthropogenic impacts on earth may yield persistent and adverse climatic conditions which may become the norm rather than an exception. Given these climatic conditions, the world population may lose its stability and these climate conditions may trigger population shifts that may be characterized by regional migration patterns or loss of population. In this commentary the purpose is to review historical views on this subject and apply a mathematical model developed to provide computational insight to human population behavior given climatic conditions that are hypothesized to occur during the next millennium. The scenarios used for this purpose is hypothetical, but they may reveal critical population dynamics which may need to be taken into consideration in addressing future climate change impacts.
Highlights
The effect of climate change on earth systems has been reported to be significant in the Intergovernmental Panel on Climate Change (IPCC) studies (IPCC, 2013)
Introduction of quantifiable and computational aspects of these concepts to population models would enhance the analysis significantly. In this commentary effect of climate change on population dynamics is discussed within a historical perspective of different philosophies that contributed to this subject
When the question is posed from the perspective of climate change effects on population and not from the perspective of effects of carrying capacity on population dynamics none of the earlier models seem to answer that question appropriately
