2025 ushers in one of the most dangerous periods in world history — on par with the 1930s and early Cold War, says Ian Bremmer, president and founder of Eurasia Group and GZERO Media. Highlighting the top geopolitical risks for the year ahead, Bremmer explores the impact of Donald Trump’s return to power in the US, the breakdown of the US-China relationship, the consequences of a rogue Russia, the future of unchecked AI development and more, plus some bright spots amid these unprecedented challenges. (This interview, hosted by TED’s Helen Walters, was recorded on January 6, 2025.) This video is part of the series "TED Explains the World with Ian Bremmer."

He meant to say that China is set to reach peak carbon emissions before 2030. The peak emissions target, not the net-zero target year (2060), is what is expected to be met ahead of schedule.
