The Use of Co-evolution to Model the Effects of Global Warming

In their paper Natural selection for least action [1] depict evolution as a Path Integral process conforming to the Principle of Least Action (PLA). From this concept, an equation of motion for environmental coevolution was derived. Co-evolution [2] is a widespread phenomenon, as any system of coupled differential equations will conform to Co-evolution. Following this idea and the link to Path Integrals and PLA it is possible to generalise Co-evolution to any system of coupled differential equations such as Global Warming; that is what is done here. Taking an approximate approach to the Lagrangians involved gives a new simple metric defined as a “Coefficient of Impact” which reflects the importance of global warming on the particular effect, empirical evidence is used to calibrate the model; the results give similar levels of importance to other published values with the exception of the duration of heat waves.
