The aim of the Climatic Research Unit (CRU) is to improve scientific understanding of the climate system and its interactions with society. Our research is directed towards answering these key questions: How and why does our climate change – past, present and future – and what are the implications? How can we quantify, reduce and communicate the uncertainty in the climate information that is developed for society?
In this passionate call to action, 16-year-old climate activist Greta Thunberg explains why, in August 2018, she walked out of school and organized a strike to raise awareness of global warming, protesting outside the Swedish parliament and grabbing the world's attention. "The climate crisis has already been solved. We already have all the facts and solutions," Thunberg says. "All we have to do is to wake up and change."
