Short summary
The link between rainfall extremes and temperature has been widely studied and a scale dependence of the rate of increase with temperature is commonly reported. Here we investigate, with high resolution data, how rainfall variability across scales, and the associated extremes, change with temperature. We confirm scaling behaviour and find that the scale invariant maximum observable singularity increases on average with greater temperature. Connection with previous results are discussed.
