The term Climate is derived from a Greek term i.e.. klima, meaning inclination is defined as the average climatic conditions of a particular region or area, together with the wind, temperature, and rainfall. Climate is mostly affected by the changes in the orbit of the earth, plate tectonics, altitude of the location, human activities, terrain, and latitude also by the burning of the fossil fuels, which in turn leads to greenhouse effect. Bound human activities have additionally been known as important causes of temperature change, and extremely doubtless the major reason for the development of global warming. Scientists actively work to grasp past and future climate by mistreatment observations and theoretical models.Climate change is an emerging global issue. It is expected to have significant impacts both in Egypt and around the world. Thus, the country is in need for taking action to prepare for the unavoidable effects of climate change, including the increase in water stress, the rise in sea level, and the rapidly increasing gap between the limited water availability and the escalating demand for water in the country. Also, weather and climate play a significant role in people’s health. Direct impacts of climate change on the Egyptians public health may include also increased prevalence of human parasitic diseases. Climate could strongly influence parasitic diseases transmitted through intermediate hosts.
