Reports on heatwaves across the globe have dominated our newsfeeds over the last few weeks, with temperatures said to have soared over the 40C mark in many parts of Europe. But across social media, not everyone is buying it. A trickle of scepticism swelled to a tidal surge, with people questioning whether temperatures are being hyped up by the wider media to drive fear and scare-monger.

In this programme, we unpick allegations made about how these temperatures are recorded - and if they are accurate. We hear from Samantha Burgess at the Copernicus Climate Change Service; Alessandro Delitala from the Sardinia Environmental Protection Agency; and Sean Buchan from Climate Action Against Disinformation.
