The effects of differences between the local and global values of the Hubble parameter on the cosmologies consistent with studies of high-redshift Type Ia supernovæare discussed. It is found that with a local Hubble parameter around 10 per cent higher than the global value then open cosmological models (such as Ωₘ = 0.3, ΩΛ=0) are prefered and if the local value is around 20 per cent higher then standard cosmological models (Ωₘ = 1, ΩΛ=0) can be recovered. Even in the case where the Hubble parameter ratio is 1, low Ωₘ open cosmologies with ΩΛ = 0 are not rejected at the 95 per cent confidence level.
