The Observatory utilised climate model data released by the Sixth Assessment Report of the Intergovernmental Panel on Climate Change and contemporary statistical methods to update the projections of hot nights, very hot days and cold days for Hong Kong. The results indicated the annual numbers of hot nights and very hot days are expected to increase significantly in this century, even in the intermediate greenhouse gas emissions scenario. Meanwhile, the annual number of cold days in Hong Kong will continue decreasing against the backdrop of climate warming.
