We have been looking in my group at the regional impacts of global climate change. The change in the climate that will result from changing in the chemical composition of the atmosphere. Change in the concentration of the atmosphere and change in the concentration of carbon dioxide and other greenhouse gases. And instead of focusing on the global scale we have been looking at the regional scale. And the results of our research pin-point a region where we think the impacts of global climate change with be quite severe in terms of temperature. However instead of focusing on the regular temperature that everyone is used to, we are focusing on a variable we call the “wet bulb temperature”. And the wet bulb temperature measures temperature conditions and humidity conditions at the same time. And the reason we choose to look at the wet bulb temperature is because it is a measurement that has direct impact on human health. For maintaining the inner temperature of a human body at around 37 degrees centigrade you need to have wet bulb temperature conditions that are 35 degrees centigrade or less. And that would enable the body to get rid of the metabolic heat that gets generated. Approach and exceed 35 degrees centigrade it will not be physically feasible for the body to get rid of that heat. And that would lead to hyperthermia and may lead to deaths for some of the people who get exposed to that. So the main finding of this study is the projection that in cities and localities around the Persian Gulf also known as the Arabian Gulf, conditions in the future, towards the end of the 21st century, would be such that the wet bulb temperature will approach and exceed 35 degrees centigrade. I would like to emphasize, however, that exceeding 35 degrees centigrade will not be a frequent occurence in the future even under the business as usual scenario. Such rare heat waves are projected to occur only once every decade or every few decades. The same modeling results that performed indicate that under scenarios in which we assume that serious mitigation efforts are being taken to reduce the emissions of carbon dioxide and other greenhouse gases, and its those conditions the impacts of global climate change on temperature conditions in southwest asia will not be as severe as in the case of the business-as-usual scenario.
