Barcelona | Two titan climate campaigners, Greta Thunberg and David Attenborough, joined forces on Monday to push politicians and businesses to step up action on climate change after a year in which schoolchildren took to the world's streets in protest.
Swedish teen activist Thunberg, who turns 17 this week, said 2019 had been "a very strange year" as millions of young people skipped school to demonstrate over slow progress on tackling climate change, inspired by her weekly vigils at the Swedish parliament.
