The Lifeboat at World's End: Moving Beyond Crisis Standards of Care.

It may be too late to avoid the climate crisis, likely to be humanity's most expensive, widespread, and enduring catastrophe. This is a qualitatively different kind of catastrophe, in which increased costs, decreased revenue, and no possibility of bailout force communities to harshly cut budgets, especially in health care. Little is known about making such brutal cuts fair or efficient, nor how to help the public accept them. The crisis presents an opportunity for bioethicists to play a crucial role, but one for which traditional approaches are inherently inadequate. Although often dismissed as heartless, Garrett Hardin's "lifeboat ethics" started a conversation about making ethical choices in global disasters-where all options are painful and unacceptable-and may provide guidance. Bioethics during the climate crisis must focus on communities rather than individuals and help survivors grieve the terrible consequences. Because today's choices will affect many generations, with the burdens falling most heavily on poor communities, we have to construct a radical bioethics to help tomorrow's health care become green, efficient, and fair.
