I'm Greer Jackson, host of the Climate Question podcast,
and this week we're looking at the new Pope's climate credentials.
The late Pope Francis was credited with being the first Catholic leader to make climate action a core part of the Church's work.
But will his American successor, Pope Leo, continue to fight global warming?
And if so, how influential might he be at home and abroad?

Hello, welcome to NewsHour from the BBC World Service.
I'm coming to you live from London.
I'm Paul Henley.
President Trump and Saudi Arabia's Crown Prince Mohammed bin Salman have signed commercial agreements worth more than $600 billion.
The White House says that the deals, which include a defence package worth over $140 billion,
are the biggest sales agreement of their kind in history.
Other elements include agreements on energy, mining and artificial intelligence technology.
Speaking at the event in the Saudi capital where he announced the deal,
Mr Trump hailed the... importance of the relationship between Riyadh and Washington.
And he heaped praise upon his hosts.
I want to thank His Royal Highness the Crown Prince for that incredible introduction.
He's an incredible man.
Known him a long time now.
