| contents | 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 $Λ$CDM is further strengthend by the new data release. For our particular models, we find that this preference increases up to $\approx 2.6\,σ$ depending on the used supernova dataset. |
