IPCC AR6 Synthesis Report SPM.4 (a) and LR Figure 3.3 (a) (Burning embers): Global Reasons for Concern in AR5 vs. AR6

Global Reasons for Concern (RFCs), comparing AR6 (2022, thick embers) and AR5 (2014, thin embers) assessments. Diagrams are shown for each RFC, assuming low to no adaptation (i.e., adaptation is fragmented, localised and comprises incremental adjustments to existing practices). However, the transition to a very high risk level has an emphasis on irreversibility and adaptation limits. The horizontal line denotes the present global warming of 1.1°C which is used to separate the observed, past impacts below the line from the future projected risks above it. Lines connect the midpoints of the transition from moderate to high risk across AR5 and AR6.
