Why Climate Literacy Is Health Literacy.

Health problems of global warming are daunting in severity and magnitude and will only get worse. Yet literacy about these problems is poor and plans to alleviate them are too early in development to be responsive to current levels of global threat and individual need.

This article considers the nature and scope of ethicists' roles in awakening clinicians and the public to this crisis and offers 4 recommendations to reduce morbidity and mortality from climate change.
