Many recent planning decisions, such as planned retreat of coastal settlements from the sea, are premised upon the scientific consensus that climate change is real. Not all local residents accept forced relocation, and some hold a radical form of rights-based belief that is hostile to government intervention into private arenas. This 'deontological libertarian' belief is related to a sceptical view of climate science. Data from an Australian survey are employed to demonstrate that climate scepticism is associated with the tendency to see private-property rights as a fundamental entitlement irredeemable in the prospect of forced retreat, regardless of compensation. The sceptical view has defensible normative elements constructed upon the framework of inviolable rights also underpinning recognised environmental and development imperatives. Appealing to absolute rights generally may be an effective way to approach the sceptical public. Rights offer a generalisable framework in which sceptics which they can see how their non-sceptical counterparts are similarly situated despite expressing a different policy preference. Although consensus is not guaranteed, communication can proceed more easily by making a common ontological terrain explicit.
