Increased heat exposure also affects the abundance and distribution of associated fish, invertebrates and algae  . Thus, coral bleaching is an indicator of thermal effects on coral habitat, fauna and flora. Bleaching is expected to continue for the GBR and Australia's other coral reef systems . Bleaching conditions are projected to occur twice each decade from 2035, annually after 2044 under RCP8.5 and annually after 2051 under RCP4.5 . Global warming of 3℃ would result in over six times the 2016 level of thermal stress .
