There's more here on Wednesday's school climate conference organised by the Green Schools Project, School 21, and WE. This was designed "to provide rigorous knowledge, skills and motivation to allow young people to change the debate in their schools and local communities".
This account is about the workshops. There were 4 of these with similar themes running. I went to a year 10 / 11 one which was skilfully designed and expertly moderated. The young people were to the fore here. Broken into cross-school groups of 4 and eventually into school groups, they began by sharing why they were there, did exercises on the problems of the language we use, and then carried out a role play on agreeing with someone who was a denier /a sceptic / just unsure / etc. It was good.
