Public dialogue on UK action on Climate Change. The Committee on Climate Change with support from Sciencewise commissioned Hopkins Van Mill to recruit for, design, facilitate and report on a public dialogue of 25 independently recruited members of the public. The 25 participants met 3 times at the Institute of Education in London on 9, 10 and 12 October 2013 in 3 individual workshops. Workshop 1 was held between 5:30-9:00 on October 9 on the climate change challenge. An understanding of the science of climate change and UK action was developed as an outcome. Workshop 2 was held between 5:30-9:00 on October 10. An understanding and knowledge of UK action on carbon emissions reduction and the implications and impacts to individuals and society emerged as an outcome. Workshop 3 was held between 9:30-13:15 on October 12. An understanding and knowledge of the climate change challenge, steps for mitigation, implications, and recommendations from the public to the Committee on Climate Change on the 4th carbon budget were developed as an outcome.
