Global warming effect on human comfort in Baghdad location

Abstract

The primary thermal anomalies and their deviation from the overall mean have a significant impact on human comfort. The study examines the phenomenon of global warming and its implications for human comfort at the Baghdad station utilizing THI equations in Fahrenheit and Kelvin for the timeframe spanning from 1961 to 2021. This timeframe is segmented into eleven intervals by computing the mean for each quinquennial period. The study indicates a rising trend in temperature at the Baghdad station particularly during the 1990s and 2000s as a consequence of global warming. The outcomes derived from the THI equation concerning comfortable months are constrained to the months of spring such as April and May, as well as the latter months of the autumn season, namely October and November. The period categorized as having the highest number of uncomfortable warm months spans from 2016 to 2021, while the comfortable months based on the K equation are restricted to the final weeks of March, April, the initial weeks of May, and the latter part of October and November. The count of uncomfortable warm months is five, while the count of comfortable months ranges from three to four. In terms of seasonal classification across regions, it is observed that winter typically exhibits a moderately cold climate, denoted by region C. Spring and autumn seasons are characterized by warm conditions, represented by region B. Lastly, summer is distinguished by elevated temperatures and is considered an uncomfortable region, indicated by region D.
