Arnold cycling with Greta Tunberg

The teenager has been using low-carbon forms of transport to travel from Sweden to Chile to eventually reach the COP25 climate summit, but has now asked for assistance in travelling to Spain, as mass anti-government protests in Santiago forced Chilean authorities to cancel the event, which will now go ahead in Madrid at the beginning of December.“It turns out I’ve travelled half around the world, the wrong way. Now I need to find a way to cross the Atlantic in November … If anyone could help me find transport I would be so grateful,” Ms Thunberg tweeted on 1 November.
