Nobel Prize laureate Sir Paul Nurse wants science, not politics, to guide the debate surrounding climate change. But how do you convince the denialists? Babita Sharma takes us through the evolving strategies of those who claim climate change isn’t real, and speaks to two young people who are trying to make a difference. UK climate activist Phoebe L Hanson founded Teach the Teacher, which gives school children the resources to engage with their teachers on climate change. Ugandan Nyombi Morris set up a non-profit organisation, Earth Volunteers, to mobilise young people like him who wanted to promote the fight against the climate crisis.
