Inspired by Pope Francis' motto that "everyone should be free to choose whether or not to migrate" the talk examines the shortcomings of international law and church teaching with regards to climate-induced migration. Therefore the talk analyzes climate change as a growing cause of flight and uses forecasts to show that millions will be forced to migrate by mid-21st century. It examines the fundamentals as well as structural deficits of international refugee law regarding climate-induced displacement. While recent legal developments offer selective protection, the framework remains fragmentary, and binding protection for refugees is largely absent. The church's response to this ecological crisis is the encyclica Laudato si' as an ethical-theological basis for the church's approach to the consequences of climate change. At this point, however, a lack of visibility and concrete naming of the victims in the encyclica becomes apparent. This in turn shows that the victims of anthropogenic climate change are often forgotten, raising the question of the church's role as an advocate for those affected. Biblical stories of flight are drawn on as a normative resource, portraying the Bible as a "migration document" that centres the experiences of the displaced and establishes protection of strangers as a core ethical duty. Finally it is shown that climate-induced migration is rarely voluntary, creating a moral obligation for climate justice and international action that prioritizes victims. The talk concludes with a call for interdisciplinary cooperation between religion, law and politics to bridge the gap between moral standards and legal reality, seizing the kairos for a fairer treatment of migrants
