Abstract
Motivated by the recent Year-2 data release of the DESI collaboration, we update our results on time-varying dark energy models driven by the Cohen-Kaplan-Nelson bound. The previously found preference of time-dependent dark energy models compared to CDM is further strengthend by the new data release. For our particular models, we find that this preference increases up to depending on the used supernova dataset.
