Reacción a "Temporarily exceeding the 1.5°C limit would have irreversible consequences"

Over the last decade, scientists have been developing multiple pathways to keep global average temperatures below the 1.5°C threshold. Plausible pathways include those that envisage the possibility of exceeding this temperature and then, by sequestering carbon dioxide en masse (either by biological systems or technologies), returning the climate system to a pre-1.5°C stage.

This new publication presents a more pessimistic view than previously thought and questions the fact that if 1.5°C is exceeded, it will not be easy to return the system to its previous state, especially because the sequestration capacities of biological systems may be highly compromised. The study highlights the urgency of emission reductions to avoid reaching 1.5°C, and indicates that adaptation will be necessary in any case, and that our adaptive capacity could be exceeded if we exceed 1.5°C.
