The event, hosted by Climate Action Grassington, will take place at The Octagon in the Grassington Devonshire Institute, North Yorkshire, and will include a screening of The People's Emergency Briefing. Professor Hill said: "Climate change and biodiversity loss are both existential threats to us. "His Majesty The King has led the march to have climate change impacts properly recognised with urgency. "Our window for influencing future climate change is closing; that is why people must embrace the challenge and take notice of the very sobering messages from this important film." The 50-minute film brings together nine leading UK scientists and experts to explain the latest evidence on climate change and nature loss.
