In this short video, Dr Natalie Douglas, a climate scientist, explains what could be some of the causes and consequences of climate change and why a 0.5 degree of temperature difference can be so important. Natalie is a Teaching and Research Fellow at the University of Surrey and is collaborating with us on the Climate Detectives school project. This video is part of the “meet the scientist” webinar organised by us to support teachers and teams of students participating in project.
