Geographical Statistical Analysis of the Relationship Between Global Climate Changes and Some Human Diseases in Iraq

Abstract

The study aims to reveal the geographical statistical analysis between global climatic changes and some human diseases in Iraq by using advanced statistical programs and the annual rate of change for some climatic characteristics prevalent in Iraq (maximum temperature, minimum temperature, rainfall, and relative humidity). The study relied on the available data on the rate of change in temperature and some extreme weather conditions and their impact on the variation of health impairment that a person can feel in light of this continuous increase in temperature, as well as the state of disease or death, which has been proven to be a reflection. The study produced a number of results, the most significant of which is that the rate of climate change that was recorded and monitored can serve as an indicator or relationship to the beginning of more severe effects in the rate of temperature and the emergence of multiple patterns of abnormal weather events. Changes in the global climate will be have detrimental by wide-ranging effects on human health and physiological comfort, and most of these effects are negative and harmful. According to me, making it clear how climatic changes affect the spread of some human diseases in Iraq is evident by gathering the various monthly and annual climatic characteristics of Iraq's climatic stations (study area) and analyzing their change for a major climatic cycle that lasted eighty years for the period (1941-2020). The population was adversely impacted by these climate changes. Infectious and internal diseases spread through the mouth through contaminated water, allergic reactions of the lacrimal system, particularly spring ophthalmia, blepharitis, acute and chronic skin allergies (eczema), contact dermatitis, as well as cutaneous leishmaniasis. The climate, with its various elements and phenomena, represents a system, and any imbalance or change in it has significant direct and indirect effects on human health. Accordingly, climate change contributes to the development of infectious diseases, especially those that are conveyed orally through contaminated water, such as cholera and various watery diarrhea, or new diseases that arise as a result of high temperatures, both directly and indirectly. The increasing temperature in the study area expands the geographical range in which disease vectors, including insects, animals, and microorganisms, can reside.
