to exceed that of reef growth by 2050, absent adaptation. In response to heatwaves, bleaching of the Great Barrier Reef is projected to occur annually if warming increases above 2.0°C, resulting in widespread decline and loss of structural integrity . Global warming of 3.0°C-3.5℃ increases the likelihood of extreme and lethal heat events in western and northern Africa  and across Asia. Drought risks are projected to increase in many regions over the 21st century .
