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
