Climate ODER: Information, Coordination, and the Time to Act

An accurate forecast can leave a response team without a usable basis for timely protection. Climate ODER, developed through Observer-Dependent Entropy Retrieval, asks what information must survive, who must retain it, and when it must be secured. In a finite model, available information supports a task when every group of indistinguishable records admits a common acceptable action. As protective options expire, a distinction can become necessary after its last timely recovery opportunity has closed. We establish this separation between preservation and action deadlines. An exact access-locator frontier shows that two initial categories can support timely recovery where immediate action requires arbitrarily many target categories. The recovered answer still carries the target information. A temporal preservation criterion constructs the distinctions that make intermediate recovery operations and final protective choices executable under a specified causal memory mechanism. Extensions give exact criteria for unequal consultation times and a declared class of monotone response rules. For distributed response, we characterize failures of shared-plan selection even when each participant’s information is individually sufficient, construct minimum-cost feature repairs, and derive their budget–deadline frontier under specified acquisition conditions. Under unreliable communication or retention, joint dependence affects the guarantee; a further criterion characterizes the existence of a shared-plan rule valid for every coupling consistent with given conditional marginals and constructs one when it exists. Constructed examples and a completed worksheet connect these results to handoffs, consultation routes, and protective capacity. An observation criterion and archival analysis plan specify the operational evidence needed to apply them. Climate justice enters through whose needs define success and how the means of meeting them are distributed.
