| Zusammenfassung |
| We consider minimum, maximum, and mean temperature records at 112 station in China and use a recent scaling approach by [Lennartz and Bunde, 2011] to estimate the minimum external trend over the past 50 years, for confidence probabilities 0.95 and 0.99. We find that the minimum temperatures, in contrast to the maximum temperatures, show a significant trend for almost all considered stations. We also study the trend as a function of the population (in 2008) and of the population increase in the past 50 years. We find a significant increase in the trend of the minimum temperature at stations with a large population increase, which suggests that part of the recent warming may be due to urban heat islands. |
