change is happening, over the past two years, we have witnessed a rise of the topic from oblivion to ubiquity and have experienced a growing emphasis on ?nding measures to prevent climate change. There is an unprecedented agreement among environmentalists, politicians, the public, and industry that we have to take effective action. Politicians are putting their creative plans to action unusually fast: Australia bans the light bulb, B- gium switches off lamps along lighted highways, and the US introduces daylight savings time two weeks earlier than in previous years. Industry, the most unlikely candidate for support, is rallying together in action groups like US-Cap or 2 Grad, and more and more consumers are offsetting their emissions through websites like myclimate.
