Authors examine the relationship between housing insecurity and lesbian, gay, bisexual, pansexual, transgender, gender-expansive, queer, and questioning (LGBTQ+) identity with mental health burdens from climate events among California adults using data from 2023 California Health Interview Survey (CHIS). The outcome was self-reported mental health burden from climate events. Primary predictors were LGBTQ+ identity and housing insecurity.

Findings: Transgender or gender-expansive and bisexual or pansexual individuals had significantly higher odds of climate-related mental health burden. High housing insecurity was also associated with greater odds. Among gay respondents, experiencing housing insecurity was associated with approximately threefold higher odds of climate-related mental health burden. Authors conclude that housing insecurity appears to be a key social driver shaping disparities in climate-related mental health among LGBTQ+ populations.
