This year is set to be the world’s hottest on record, likely shattering the aspiration to limit global warming to 1.5C above pre-industrial levels.

So where does this leave COP29, the upcoming UN climate conference in Azerbaijan?

This week Inside Science is asking, are climate summits really working? What is the point of them - and are they doing enough?

Joining Marnie Chesterton to discuss this are:

- Joanna Depledge, expert on international climate negotiations at the University of Cambridge
- Mark Maslin, climate change professor from University College London (UCL)
- Jim Watson, professor of energy policy, also from UCL
