Abstract
Both natural and anthropogenic factors can influence the width of growth rings. In this paper we discuss the influence of one specific factor, war. The first part will begin with discussing the effects of biotic and abiotic factors on the width of tree rings. This is followed by explaining how clouds are made. By talking as well about the influence of clouds and cloud condensation nuclei on tree rings, the effects of two war scenarios on climate and growth rings can be discussed. One of these scenarios is a nuclear war, which can potentially create a ‘nuclear winter’ by dropping the temperature with several degrees. This can, by inhibiting solar radiation as well, decrease the width of tree rings. The other war scenario, the oil fires of Kuwait, should have an effect on width of growth rings as well. This is based on the observation that the average solar radiation decrease was much higher than the fluctuating solar radiation, which already showed an effect on the width of growth rings. This suggests that the influence of war could be visible in growth rings, at least in the case of the Kuwait fires.
