On November 29th school pupils in Northern Ireland were again striking to protest about lack of action from the adult generation to address the threat of climate change, inspired by Greta Thunberg’s initial protest in late August 2018, when she took up position outside Sweden's Parliament for the first time. She held a simple sign, black letters on a white board that said, "School Strike for Climate."

"It felt like I was the only one who cared about the climate and the ecological crisis," she told the BBC.  The 15-year-old was by herself, but not for long.

Support for her cause among school pupils has mushroomed, with strikes started around the world, and the message spread with the hashtag #FridaysForFuture.
