In the more than 130 years since Shanghai been taking annual temperature readings, according to municipal meteorological experts, the city’s five hottest years have all occurred in the last decade: 2002 (17.8 degrees Celsius), 1998 (18.0), 2004 (18.1), 2006 (18.3) and, now, 2007 (18.4), the hottest year so far.
Compared with previous years, this year has been particularly warm in Shanghai. February, May and July this year registered record setting monthly averages. In most of eastern China, the monthly averages were more than one degree higher than the historical records, in some areas over two degrees warmer. [Full Text in Chinese]
