In this fourth episode we discuss climate risk and attribution – understanding how man-made ‘forcing factors’ can affect the intensity and probability of extreme weather events such as heat waves and extreme rainfall leading to droughts and flooding. As our understanding of this emerging and complex area of climate science increases we may be better placed to understand climate risk and avoid or adapt to extremes of weather. To unpack this issue we are joined by Dr Neven Fučkar, Marie Sklodowska-Curie Individual Fellow, COP26 Fellow in Climate Risk, and Departmental Tutor at the University of Oxford and Prof Liz Bentley, Chief Executive of the Royal Meteorological Society.
