The current record of 29.1 degrees, set in 1889, looks likely to be broken Hong Kong will have had its hottest October in 100 years if today's temperature is more or less the same as yesterday's at 29.4 degrees Celsius, according to the Observatory's records. Speaking during the launch of a new Greenpeace website to warn people about global warming yesterday, Mok Hing-yim, senior scientific officer at the Observatory said that Hong Kong would be very likely to break the record. The current record was set in 1889, when the highest mean temperature reached 29.1 degrees. Mr Mok said the problem was that the northeast monsoons, the coolant for south China that comes from the mainland, had come late. He said the colder air also seemed weaker this year, and lasted for shorter periods than usual. This resulted in a smaller drop in mean temperatures than usual. However, while Hong Kong has had a hot October, August and September had been abnormally cool. 'Long-term climate analysis, meanwhile, shows that mean temperatures are going up,' Mr Mok said. 'It is getting hotter. The local annual mean temperature can be expected to rise 3.5 degrees to 26.5 degrees in the last decade of this century, 2090-2099, compared with the temperatures of the period from 1961 to 1990.' The hot October, however, should only be taken as an aberration. One month's data could not imply much, he said, noting that in-depth analysis of climate data over a long period of time was needed to determine whether this was a regional or global trend. The Observatory estimated that if temperatures in Hong Kong continued to rise, the number of days in a summer with temperatures over 33 degrees would increase from the average of 11 in 1990 to 24 by the end of the century. 'The problem of climate change is intimate,' Mr Mok said. 'The consequences of global warming are not that remote. Like the reduction of habitat for polar bears, it is happening all around us. 'We must act now. Save the use of energy and treasure the Earth,' he said. Greenpeace climate campaigner Gloria Chang Wan-kei added that people should not feel hopeless over climate change. 'If people can understand the truth and speak out to urge the government to restrict the emissions of carbon dioxide and to urge the power companies to use renewable energy instead of coal, the crisis of climate change can be relieved,' she said. The green group's website at http://www.greenpeace.org/china/ch/climate-truth/you-cant-escape-the-he… , is the first of its kind. It is aimed at educating people about climate change in a vivid and lively way.
