Environmentalism and environmental change as it affects Canadian defence policy and operations

Technical Report:

Abstract

The greenhouse effect is described, along with the anthropogenic factors that are considered to influence climate. Various types of climatic models are outlined and critically compared, since much of the present debate about the possible impacts of the greenhouse effect is centered on which of the many forecasts is representative of what can be expected in the early 21st century. The central focus of this comparison is to summarize the findings of the models and arrive at an overall consensus on rates of climatic change. It is seen that models are, at their present state of development, only able to provide an internally consistent picture of a plausible future climate. A general consensus is that the annual global average temperature will rise to 16.8-19.8{degree}C by the year 2035. The largest sources of uncertainty in modelling appear to be the feedback from oceans, clouds, ice-albedo, and possibly lapse rate and water-vapor changes. The repercussions of climate change that may influence the Canadian Forces in their daily operations and in strategic planning are briefly discussed. 21 refs., 4 figs., 1 tab.
