This study examined the impact of climate on widowhood and divorce, and the subsequent effects on individual vital rates and life&#8208;history outcomes over 54&#8201;years in a snow petrel ( Pagodroma nivea ) population. We found that environmental conditions can affect pair&#8208;bond dynamics both directly and indirectly. Divorce was adaptive, occurring more frequently after breeding failure and leading to improved breeding success. Divorce probabilities also increased under severe climatic conditions, regardless of prior breeding success, supporting the &#8216;Habitat&#8208;mediated&#8217; mechanisms. Overall, pair&#8208;bond disruptions reduced subsequent vital rates and lifetime outcomes. Climate forecasts from an Atmosphere&#8211;Ocean General Circulation Model projected increased male widowhood rates due to decreased sea ice negatively affecting female survival, despite considerable uncertainty. These findings highlight the importance of environmentally induced changes in demographic and pair&#8208;bond disruption rates as crucial factors shaping demographic responses to climate change.
