"Educationists and student groups have joined environmental organisations to condemn government plans to drop debate about climate change from the national curriculum for under-14-year-olds in English schools. The Guardian revealed on Monday that new draft guidelines for children in key stages 1 to 3 make no mention of it in the geography syllabus, with only a single reference to how carbon dioxide produced by humans affects the climate in the chemistry section. All references to sustainable development have also been dropped in a move widely interpreted as the result of political interference. The Department for Education is now consulting on the proposed changes. Doug Bourn, director of the development education research centre at the Institute of Education, said dropping all mentions in the proposed slimmed-down geography curriculum allowed teachers to choose whether to include climate change but would make it easy for them to ignore it. 'Climate change is important,' he said. 'The danger is that it will now not be taught at all or that the vacuum could be filled by people who are not positive about it, like deniers.'"
