Detection of changes in temperature extremes during the second half of the 20th century
- Demonstrates the early detection of a significant anthropogenic influence in temperature extremes with the exception of changes in warm days
- 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
