  • States that since 1950, the warmest and coldest days and nights of the year have become warmer
  • Compares these observations with climate model simulations
  • Shows a significant human influence on patterns of change in extremely warm nights
  • Detects human influence on cold nights and days, although less robustly, but there is no detection of a significant human influence on extremely warm days
  • Concludes that in the future, extreme temperatures are expected to intensify considerably, with adverse consequences for human health
