2、 future Winter temperature trends and suggestions for modeling their impact on mortality Eve Titon Tinhinane Talbi Jeanne Bessiere While some studies have been carried out on the prediction of heat waves and the resulting mortality,1 there is relatively little work on the mortality risk associated w
3、ith cold temperatures.In fact,the global rise in temperatures is leading to an increasing number of summer heat waves,with a consequent impact on mortality,while winter death rates have been declining overall since 1990.However,the impact of low temperatures on the human body is complex:As human bei
