The Intergovernmental Panel on Climate Change may launch its latest report on the issue in Hong Kong next year during an international conference staged for engineering groups. The International Conference on Climate Change will be held for three days from May 29. Co-organised by the Hong Kong Institution of Engineers and three other professional engineering bodies, the conference will be the biggest gathering on climate change to be held in the city. The gathering also is being supported by the World Meteorological Organisation and the European Commission's office in Hong Kong. A source close to the organiser said the panel, operating under the UN, was considering using the conference to launch part of its fourth assessment report on climate change. The panel issued its third report five years ago. The source also said political leaders from the European Union might join the conference. The organisers are now calling for papers to be presented at the gathering.
