Emergence of heat extremes attributable to anthropogenic influences
- States that climate scientists have demonstrated that a substantial fraction of the probability of numerous recent extreme events may be attributed to human-induced climate change
- Identifies the first record-breaking warm summers and years for which a discernible contribution can be attributed to human influence
- Finds a significant human contribution to the probability of record-breaking global temperature events as early as the 1930s
- Finds that, since then, all the last 16 record-breaking hot years globally had an anthropogenic contribution to their probability of occurrence
- Finds that aerosol-induced cooling delays the timing of a significant human contribution to record-breaking events in some regions
- Concludes that without human-induced climate change recent hot summers and years would be very unlikely to have occurred
