Global warming has led to melting of polar glaciers and serious environmental impacts to our earth. It is important for us to combat climate change and mitigate its impacts. With an aim to enhancing public awareness on climate change, the Environmental Campaign Committee, the Polar Museum Foundation, the Environmental Protection Department, the Hong Kong Observatory and the Hong Kong Science Museum jointly organize the 'Global Warming and Climate Variation' Seminar Series. Riding on the success of the first four seminars, the fifth public seminar cum exhibitions will be held on 26 February 2011 (Saturday), at the Lecture Hall of Hong Kong Science Museum. Dr. William Yu, Head of Climate Programme of WWF, and Ir. Daniel M. Cheng, President of Hong Kong Environmental Industry Association, have been invited to share their knowledge and insights with the public in the seminar. The exhibition will showcase a large number of precious photos taken by Dr. Rebecca Lee, founder of the Polar Museum Foundation, during her polar expeditions to illustrate the close relationship between climate change and the Poles.
