The burning topic of the day is the complex of Global Warming, Climate Change and Sustainability. Figure 1 depicts an integrated framework comprising the components involved in the phenomenon of Global Warming. It has been constructed by scientists, while this articles is written from the point of view of HVAC. Accordingly, amongst the components of the framework listed, the terms that catch the eye are Temperature, Concentrations, Emissions, Adaptation and Mitigation. This effort will therefore focus on these components. Attention will also be paid deliberatelly to provide a bridge between the science and HVAC engineering.
