Just in the last two years, we have seen the final Planck data release, measurements of the local value of the Hubble constant nearing two percent, the first standard siren measurement, and new strong lens time delay cosmological measurements. Even with a number of re-analyses and systematic checks on these various analyses, tension of the local H_o measurements and the CMB inferred H_o value remains, and excitement continues to increase amongst cosmologists regarding the source of tension. In this workshop, we are asking what's next for all these experiments and analyses. This workshop will be focused on analyses coming out in the next year or two, looking at what we can expect before the next generation of experiments come online. We want to hear about new ideas to push down at systematic uncertainties in current analyses, what lingering issues remain unresolved and what can be done to solve them. This workshop will be a unique chance for scientists who work on different probes to think together about what can be done to better understand what is driving the tension and how the next round of analyses can address various concerns.
