Discrete climate hazards including storms , floods , heatwaves, wildfires and drought  have significant negative consequences for mental health . A large body of research identifies the impacts of extreme weather events on PTSD, anxiety and depression; much of the research has been done in the USA and the UK, but a growing number of studies find evidence for similar impacts on mental health in other countries, including Spain , Brazil , Chile , Small Island Developing States  and Vietnam . Approximately 20-30% of those who live through a hurricane develop depression and/or PTSD within the first few months following the event , with similar rates for people who have experienced flooding . Studies conducted in South America and Asia indicate an increase in PTSD and depressive disorders after extreme weather events . Evidence is lacking for African countries . Children and adolescents are particularly vulnerable to post-traumatic stress after extreme weather events , and increased susceptibility to mental health problems may linger into adulthood .
