In this study, predictions are made as to how rapid warming and ocean acidification are likely to affect benthic flora and coastal ecosystems of the north-east Atlantic in this century based on global evidence from the literature as interpreted by the collective knowledge of the authorship. We predict that kelp forests will die out in the south due to warming, maerl habitat lost in the north through acidification, seagrasses will proliferate, associated epiphytes will switch from calcified algae to diatoms and filamentous species, and invasive species will thrive. Thus, structurally diverse seaweed canopies with associated calcified and noncalcified flora may be replaced with simple habitats dominated by noncalcified, turf-forming seaweeds.
