A further increase in the frequency and/or intensity of water-related extremes  will also increase consequent risks and associated losses and damages , primarily for exposed and vulnerable communities globally . After assessing the future potential of currently available technologies to reduce projected water-related climate impacts, there is evidence that residual impacts will remain after adaptation for most adaptation options and levels of warming, with increasing residual risks at higher warming levels . Financial, technical and legal support will be needed when hard limits are transgressed and loss and damage occurs . Knowledge gaps remain regarding quantified information on limits and constraints to adaptation in the water sector.
