High Quality Content by WIKIPEDIA articles! Planet Relief was a proposed BBC television special dealing with the issue of global warming, originally scheduled for broadcast in January 2008. The programme, which had been in development for 18 months, was meant to be similar to previous BBC programmes such as Comic Relief and Sport Relief. However, it was cancelled before it was broadcast, allegedly because the BBC was concerned that it would be "biased" towards promoting responses based on acceptance of mainstream climate change science.
