Tim Marshall is one of the world’s most successful authors on foreign affairs. He’s the writer who put the ‘geo’ into geopolitics with his multi-million-selling books Prisoners of Geography and The Power of Geography. Marshall’s principal argument is that without geography we cannot understand the world. Geography explains why Vladimir Putin wanted to annex Crimea; to remain a world power, Russia needs to maintain a navy and since Russian ports are frozen for half the year, Putin wants to control the warm water port of Odessa. In October 2024 Marshall came to the Intelligence Squared stage just weeks out from the pivotal election in the United States to discuss how politics and geography intersect on the world stage. He helped us to understand what’s at stake for the world in 2024 and how geography will underpin the geopolitical conflicts of the future. Joining him onstage to discuss it was science communicator, oceanographer and physicist, Helen Czerski.
