Global climate change and health in Canadian children.

Climate change is a reality. Numerous expert authorities warn of the critical need to undertake and adapt environmental efforts to protect human health. Climate change is accelerating, and countries in high latitudes, such as Canada, are experiencing climate change more directly and, for some end points, more dramatically than mid- and low-latitude countries. Children are vulnerable to climate change health effects, and physicians and other health care providers need to be ready to identify, manage, and prevent climate change-related health hazards. This practice point highlights specific, climate change-related threats to the health of children and youth, and provides resources for health care providers. Climate challenges and their health impacts on children are described, based on key Canadian reports and scientifically referenced information. Enhanced awareness of the immediate and longer-term health effects of climate change on children allows physicians and other health care providers to counsel families and practice more effectively.
