The burning embers on risks for humans  differentiate between present and medium adaptation conditions, drawing on SSP2 and SSP4 , and high adaptation conditions, drawing on SSP1 and papers using various temperature adjustment methods . There is high confidence that the risk is already moderate now because it has been detected and attributed with high confidence . The transition from moderate to high risk for human health is assessed to happen after 1.5℃ GWL in a scenario with present to medium adaptation and implies a two- to threefold increase  in magnitude of consequences such as mortality, morbidity, heat stress and thermal discomfort . At this level, the risk will also become more persistent across the continent due to increase in heat events exceeding critical thresholds for health  .
