As extreme weather events intensify globally, China is grappling with a new challenge: fake disaster videos that spread rapidly online. The government has pledged to combat misinformation, but the task is becoming increasingly complex as artificial intelligence (AI) technology advances.

The BBC's China correspondent, Stephen McDonell, explains how identifying AI-generated content is not just difficult for humans, but also poses significant challenges for digital forensics experts. These videos can be indistinguishable from real footage, raising questions about the role of AI in shaping public perception during emergencies.

With misinformation posing serious risks—from panic to harmful actions—authorities are stepping up their efforts to distinguish between genuine and fabricated content. However, the speed at which these videos spread makes early detection and response a significant hurdle.

The issue extends beyond China; it's a global concern as AI continues to evolve. As Stephen notes, the ability of AI to mimic human experiences creates an ethical dilemma: how do we trust our screens in times of crisis?
