The global health effects of climate change are not well quantified today and are likely to increase in the future, with lower-income countries bearing the brunt of greater food insecurity, increased rates of chronic respiratory illnesses, and shifts in vector-borne diseases. This section explores the global health nexus between climate change and pollution and the possibilities for a more coherent policy approach to these issues
