Abstract
A growing body of research has documented the phenomenon of climate change anxiety (CCA), defined broadly as nega-
tive cognitive, emotional, and behavioral responses associated with concerns about climate change. A recently validated
scale of CCA indicated two subscales: cognitive emotional impairment and functional impairment (Clayton & Karazsia,
2020). However, there are few empirical studies on CCA to date and little evidence regarding whether CCA is associated
with psychiatric symptoms, including symptoms of Major Depressive Disorder (MDD) and Generalized Anxiety Disorder
(GAD), and whether engaging inindividual and collective actionto address climate change could buffer such relationships.
This mixed methods study draws on data collected from a sample of emerging adult students (ages 18–35) in the United
States (N = 284) to address these gaps. Results indicated thatboth CCA subscales were significantly associated with GAD
symptoms, while only the Functional Impairment subscale was associated with higher MDD symptoms. Moreover, engag-
ing in collective action, but not individual action, significantly attenuated the association between CCA cognitive emotional
impairment and MDD symptoms. Responses to open-ended questions asking about participants’ worries and actions related
to climate change indicated the severity of their worries and, for some, a perception of the insignificance of their actions
relative to the enormity of climate change. These results further the field’s understanding of CCA, both in general and spe-
cifically among emerging adults, and suggest the importance of creating opportunities for collective action to build sense of
agency in addressing climate change.

Introduction
Increasing evidence indicates that climate change will have
far-reaching impacts on human health, including mental
health (Doherty & Clayton, 2011; Hayes etal., 2018). A
large body of literature has investigated the mental health
consequences of one marker of climate change, weather-
related disasters, showing elevated rates of common psy-
chiatric conditions like Major Depressive Disorder (MDD)
and Generalized Anxiety Disorder (GAD) (Goldmann &
Galea, 2014; Hrabok etal., 2020), and a growing number
of studies also suggest that rising temperatures can impair
mental health and increase risk for suicidal behavior (Burke
etal., 2018; Cianconi etal., 2020; Heo etal., 2021). How-
ever, a focus on weather-related disasters and temperature
misses the full range of climate change exposures, including
its subtler indicators, and their mental health consequences.
Recent research indicates that even the existential threat
of climate change may be associated with adverse mental
