Environmental activist Greta Thunberg’s searing address at the United Nations earlier this week earned enthusiastic praise from climate researchers, with many saying that the 16-year-old has found ways to raise awareness of climate science, galvanize support and resonate with people in ways that they have struggled to for decades. “Speaking as a climate change scientist who has been working on this issue for 20 years and saying the same thing for 20 years, she is getting people to listen, which we have failed to do,” said Saleemul Huq, director of the International Centre for Climate Change & Development in London.
