The American lawyer, oil lobbyist and master strategist Don Pearlman is said to have chain-smoked his way through almost every UN climate gathering from the early 1990s until his death in 2005.

Some of those who saw Pearlman operate in Kyoto, where the first legally binding international agreement on climate change was agreed in 1997, say he created the playbook for stalling climate talks. The Kyoto protocol was never ratified by the United States, and Pearlman is now the subject of a major play, Kyoto, which has just transferred from London to the Lincoln Center in New York.

As the COP30 climate summit takes place in Brazil, Climate Question Host Jordan Dunbar has been telling our friends on The Global Story podcast the true story of the man once nicknamed "the high priest of the carbon club".

With episodes each weekday, The Global Story is where the world and America meet. The world is changing. Decisions made in the US and by the second Trump administration are accelerating that change. But they are also a symptom of it. With Asma Khalid in DC, Tristan Redman in London, and the backing of the BBC’s international newsroom, The Global Story brings clarity to politics, business and foreign policy in a time of connection and disruption.
