Climate change is increasingly recognized as having multiple adverse mental health effects, many of which are just beginning to be understood. The elevated rates of suicides observed in some communities affected by climate change and rising rates of suicide in the United States as climate change intensifies have suggested the two may be associated. We searched PubMed and PsycInfo using the terms climate change and suicide, and provide here a review of the current literature on climate change and suicide that explores possible associations and methodological issues and challenges in this research.

Background: Terrorism represents a major public health threat throughout the world. Bombings of the United States Embassies in East Africa in 1998 resulted in extensive physical and emotional casualties., Methods: This study examined posttraumatic stress reactions, worry, and feelings of safety in the workplace in the context of injury in a convenience sample of 21 individuals directly exposed to the bombing in Dar es Salaam, Tanzania. Eight months postbombing, participants completed a self-report instrument examining demographics, exposure, injury, initial reaction, posttraumatic stress, worry, and feelings of safety in the workplace. Descriptive statistics and multiple regression were used to analyze the data. The "Impact of Event Scale-Revised" measured current posttraumatic stress., Results: Report of injury predicted posttraumatic stress, intrusion, and arousal but not avoidance/numbing. Injury and intrusion were significant predictors of ongoing worry., Conclusions: Even relatively minor injury may be associated with ongoing posttraumatic stress and worry. The participants in the sample were all highly exposed which, along with the small sample size, may have limited the ability to establish other expected relationships.
