The Panel Plus for 2 July 2026

An extra half hour of The Panel with Mark Leishman, where to begin, he's joined by Nights host Susana Lei'ataua. Then: the European heatwave is scorching citizens and breaking records with temperatures leapfrogging 40 degrees Celsius.

Mark talks to Mat Santamouris, a professor at the Faculty of Art Design and Architecture at the University of New South Wales.
