Although the embers do not indicate the decade in which certain risks are projected to occur, clearly this depends strongly on the level of mitigation action as well as the degree of adaptation. Hence, the ember diagram  is shown alongside a graphic illustrating possible global temperature time series emerging from alternative future scenarios assessed by WGI AR6 which imply different levels of mitigation effort. For example, in a scenario with a high level of mitigation effort  reaching net zero emissions in the 2050s, it is extremely likely that global warming remains below 2ºC and more than 50% likely that it will remain below 1.6℃ . On the other hand, a level of 2°C warming is extremely likely to be exceeded during the 21st century under the three scenarios assessed by WGI AR6 in which GHG emissions do not fall below current levels before mid- century  . WGI AR6 has assessed that 'global surface temperature averaged over 2081-2100 is very likely to be higher by 1.0°C-1.8℃ under the lowest CO2 emission scenario considered in this report  and by 3.3ºC-5.7°C under the highest CO2 emission scenario '. However, almost all scenarios assessed by IPCC AR6 WGI reach 1.5℃ global warming level in the early 2030s .
