Climate anxiety does not need a diagnosis of a mental health disorder

In a recent Correspondence in The Lancet Planetary Health, Sampaio and Sequeria1 state that "climate anxiety is not yet considered a mental health disorder" and might be a risk factor for mental disorders, which is something that we contest. The authors further claim that "climate anxiety occurs mainly in lower-income countries located in areas that are more directly affected by climate change",1 which we regard as doubly incorrect: first, there are no substantial differences in climate anxiety between countries with different average incomes,2 and second, it is misleading to aver that lower income countries are more directly affected by climate change. Rather, the issue is one of impact visibility and adaptation capacity.
