Heat stroke: The person’s cooling system‚ controlled by the brain‚ stops working and the internal body temperature rises to the point at which brain damage or damage to other internal organs may result (temperature may reach 105 F or greater [40.5 C or greater]). Stay hydrated as prevention is the key. Develops rapidly. Heat stroke happens in the following two ways: The classic form occurs in people whose cooling mechanisms are impaired. The exertional form occurs in

For many years humans have been blamed for causing global warming. Global warming‚ however‚ can be caused by natural effects. One reason is that the earth is constantly going through periods of warming and cooling. Second the two most abundant greenhouse gases water vapor‚ and carbon dioxide both occur naturally. Third the earth is not the only planet that has had a change in temperature over the past few years‚ other

Jet Streams – veritable rivers of air‚ generated by earth’s rotation and air-pressure gradients Fronts – regions of rapid weather change Monsoons – The seasonal airflow created by major differences in cooling and heating between oceans and continents‚ usually bringing extensive rain.

affect the annual cooling and heating energy (Pan‚ Dongmei‚ Chan‚ Deng‚ and Lin‚ 2012). This was tested in four different climate zones‚ Guangzhou‚ Shanghai and Beijing. The results were that the increase in insulation thickness increased energy saving‚ especially Beijing because of the heating energy use in the region (Pan‚ Dongmei‚ Chan‚ Deng‚ and Lin‚ 2012). For the Guangzhou and Shanghai regions‚ the thickness of insulation did not affect the sum of the heating and cooling

building in China converts heat energy collected from a horitzontal water sourced heat pump as well as a vertical soil sourced heat pump into energy for lighting as well as for the heating and cooling of the building. Z.E.B. Singapore isn’t in a four-season part of the world‚ thus‚ it doesn’t require a cooling and heating system as efficient as the one of the Z.E.O. building in China. Besides that‚ the types of materials used in each building differs based on different angles of importance. As one
