Urban Heat Island Mitigation Strategies: 2021 Update

This literature review briefly examines methods to mitigate urban heat islands. Climate change is already increasing the number of high-heat days, a trend that will continue in the coming years. It is, therefore, important to bolster the resilience to heat of cities and buildings for the benefit of the health of the population.

Climate change and heat vulnerabilities of Canadian workers: Focus on the Central and Western provinces of Canada

Global warming could have particularly severe impacts on Canada. It is estimated that temperatures in Canada increased at roughly twice the global mean rate over the 1948–2016 period, with a mean annual increase of 1.7°C compared to a global increase of 0.8°C. Periods of extreme heat have become more frequent and more intense in most provinces. Without appropriate preventive actions, these changes could lead to an increase in mortality and morbidity rates, affecting, among others, urban…

Multiple chemical sensitivity syndrome, an integrative approach to identifying the pathophysiological mechanisms

Multiple chemical sensitivity syndrome (MCS) is a chronic disorder characterized by multiple recurrent non-specific symptoms triggered or exacerbated by exposure to odours present in the environment at low concentrations—concentrations tolerated by most people.

People who are the most severely affected suffer from a chronic impairment that prevents them from functioning normally in their social and professional lives.

Various epidemiological studies have found different…

Tools and Methods for Integrating Health into Climate Change Adaptation and Mitigation Policies and Strategies

This paper presents the results of a scoping review of the literature on existing tools and methods for integrating health concerns into climate change adaptation and mitigation policies and strategies. It is intended for public health actors who may be involved in the development of such policies and strategies. It may also be of interest to other actors who would like to further integrate the health dimension into their actions aimed at combating climate change.
