The coming health crisis: Indirect health effects of global climate change

Abstract

Global climate change threatens the health of hundreds of millions of people. While much has been written about the direct impacts of climate change on health as a result of more severe storms, more intense heat stress, changes in the distribution of infectious disease, and reduced air quality, we are concerned that the indirect impacts of a disrupted climate system may be orders of magnitude more important in terms of the human suffering they cause. Because these indirect effects will result from changes in biophysical systems, which are inherently complex, there is significant uncertainty about their magnitude, timing, and location. However, the uncertainty that shrouds this issue should not be cause for complacency; rather it should serve as an organizing principle for adaptation to its ill effects. © 2011 Faculty of 1000 Ltd.
