Children will take up the battle to beat climate change from the classroom as part of a revamped geography curriculum for all 11 to 14-year-olds. Under the proposals, pupils will be taught about pressing issues such as global warming and poverty, in a major revamp of the secondary curriculum to be announced by ministers next week. The proposed changes are part of a new flexible curriculum that is aimed at giving teachers more scope to bring in topical issues relevant to the changing world. The film, which will form part of a climate change pack, documents the former US vice president's personal mission to highlight the issues surrounding global warming and inspire actions to prevent it. "The debate over the science of climate change is well and truly over, as demonstrated by the publication of today's report by the IPCC," said Mr Miliband. "Our energies should now be channelled into how we respond in an innovative and positive way in moving to a low carbon future. "I was struck by the visual evidence the film provides, making clear that the changing climate is already having an impact on our world today, from Mount Kilimanjaro to the Himalayan mountains. "As the film shows, there's no reason to feel helpless in the face of this challenge. Everyone can play a part along with government and business in making a positive contribution in helping to prevent climate change." Mr Johnson said that influencing the opinions of children was crucial to developing a long term view on the environment among the public.
