A scenario of human thermal comfort in Mexico City for 2CO(2) conditions

Applying the concept of effective temperature (ET), a scenario of human bio climatic conditions for Mexico City is presented by using results from both GCM regional predictions for CO2 doubling and temperature trend projection from an urban station. Current and future bioclimatic maps for Mexico City and its conurbation are presented. Current environmental conditions will l ikely change toward a warmer atmosphere due to both the urbanization proces s and global greenhouse effect. The impact on the population will be more i mportant during the warm season (March-May) when the bioclimate of the city will likely shift away from current neutrality to the next comfort scale c ategory (ET 24-27 degreesC) of warm conditions covering most of the capital city.
