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 and welcome to NewsHour from the BBC World Service.
I'm Celia Hatton and I'm coming to you live from our studio in London.
President Trump is in Saudi Arabia, the first country on his four-day tour of Gulf states.
Diplomatically, he's expected to focus on relations with Iran and the conflict in Israel.
But of equal, if not more,
importance on this trip are the big dollar deals that are expected to be signed on this tour.
Let's go live to the region and to our chief international correspondent, Lise Doucette.
Lise, can you set the scene for us?
What's been happening so far?
What a scene it is, Celia, in the Saudi kingdom.
President Trump must be very happy indeed.
We've seen him smiling every time he's taken to yet another elaborate and luxurious royal palace.
He never hides how he loves dealing with the powerful, the rich, the royal.
