de Sitter Swampland, H0 tension & observation

We present a model relieving this tension, which predicts a turning at small positive redshift z⁎ that is dictated by present-day matter density ωm. This feature is easily identified by homogeneous surveys covering redshifts z≤0.1. We comment on the implications for the Swampland program.
