英文摘要: We use the Global Historical Climatology Network – daily database to calculate a nonparametric statistic that describes the rate at which all-time daily high- and low-temperature records have been set in nine geographic regions (continents or major portions of continents) during periods mostly from the mid-20th century to the present. This statistic was defined in our earlier work on temperature records in the 48 contiguous United States. In contrast to this earlier work, we find that in every region except North America all-time high records were set at a rate significantly (at least 3σ) higher than in the null hypothesis of a stationary climate. Except in Antarctica, all-time low records were set at a rate significantly lower than in the null hypothesis. In Europe, North Africa and North Asia the rate of setting new all-time highs increased suddenly in the 1990s, suggesting a change in regional climate regime; in most other regions there was a steadier increase. © 2017 Royal Meteorological Society
