%In addition to the headline figure $H_0 = 73.3^{+1.7}_{-1.8}$ km s$^{-1}$ Mpc$^{-1}$, the H0LiCOW collaboration reports a descending trend of $H_0$ with lens %redshift with a low statistical significance but no indication that systematics are at play. If substantiated going forward, early Universe solutions to the %Hubble tension will struggle to explain this trend. Here by binning a dataset comprising megamasers, cosmic chronometers, Type Ia SNe and BAO according to %redshift, we recover an independent similar trend with a statistical significance of $2.1 \, \sigma$.
%\noindent
We consider a low redshift $(z<0.7)$ cosmological dataset comprising megamasers, cosmic chronometers, type Ia SNe and BAO, which we bin according to their redshift. For each bin, we read the value of $H_0$ by fitting directly to the flat $\Lambda$CDM model. Doing so, we find that $H_0$ descends with redshift, allowing one to fit a line with a \textit{non-zero} slope of statistical significance $2.1 \, \sigma$.
Our results are in accord with a similar descending trend reported by the H0LiCOW collaboration.
If substantiated going forward, early Universe solutions to the Hubble tension will struggle explaining this trend.
