The temperature in the inner urban areas of Hong Kong is predicted to rise by two to three Celsius degree in 30 years’ time, according to the latest scientific study by researchers at the Department of Land Surveying and Geo-Informatics (LSGI) of The Hong Kong Polytechnic University (PolyU). The study was done by PolyU Professor Janet Nichol and her research student Mr To Pui-hang, together with Chinese University’s Professor Edward Ng Yan-yung, using remote sensing technology and satellite images. They have mapped the distribution of temperatures for both daytime and nighttime over Hong Kong at decadal intervals up to 2039, taking into consideration the temperature change due to greenhouse-induced warming as well as the impact of urbanization. The latter is known as the Urban Heat Island (UHI) effect. Read More
