I have yet to listen to it. it came up in a news feed and since it was from a reputable source I thought others may be interested

 

[Bandersnatch]

The discussion title is 'Is cosmology in crisis?', not 'cosmology in crisis'.

The podcast is a recorded popular outreach session about the recent tension in Hubble measurements, in the form of a panel discussion by some professional cosmologists.
There's maybe 30 min description of what the tension is, followed by ~20 min of each panellist giving their gut feeling on whether this means the need for new physics or boobery in the data - on which opinions are about evenly divided. It concludes with audience questions.

Might be worth linking to when somebody asks about the tension again and you don't feel like composing an answer yourself.
