After our fact-checking series, Scotland and the Climate Crisis, came to an end, Ali and Paul spoke to climate systems expert Professor Gabi Hegerl from the University of Edinburgh and Edinburgh Climate Change Institute.

She explained how the climate is already being impacted by human-caused climate change, and how we can tell that the current impacts on the world are directly attributable to greenhouse gases pumped out by human activity.

Then, in Paul's Curiosity Corner, we looked at the controversy over the Ultra Low Emissions Zone in London, and how some of the opposition has been hijacked by conspiracy theorists.
