Coral reefs are among the most sensitive ecosystems affected by ocean warming and acidification, predicted to collapse over next few decades. Reefs shift from net accreting calcifier-dominated systems with exceptionally high biodiversity eroding algal-dominated dramatically reduced biodiversity. Here, we present a two-year experimental study examining responses of entire mesocosm coral reef communities (+2 °C), acidification (-0.2 pH units), combined future °C, -0.2 pH) treatments. Contrary modeled projections, show that under conditions, these structure composition yet persist as novel calcifying Our results suggest if climate change is limited Paris Climate Agreement targets, could in an altered state rather than collapse.
