What to know about this year’s UN climate talks

Thousands of delegates, lobbyists, and journalists have gathered in Antalya, Turkey, for COP31, the annual UN climate talks. But this year’s negotiations are taking place against a particularly tense geopolitical backdrop, as the world falls further behind the Paris Agreement’s goals.

Energy prices are soaring, and there are big questions about how countries will tackle the climate crisis. Expect a lot of back and forth on fossil fuels and climate finance, and whether negotiators can agree on meaningful action.

Here’s what you need to know about COP31.

How Chinese short dramas became AI content machines

China’s short drama industry is fueled by bite-sized, melodramatic, and smutty shows built for smartphone scrolling. Now, many are being made entirely with AI: no actors, camera operators, cinematographers, or CGI specialists required.

An average of 470 AI-generated short dramas were released every day in January. Production timelines have shrunk from months to weeks, while costs have dropped by up to 90%. Storytelling is also increasingly driven by performance data.

The format is rapidly expanding overseas while reshaping the work of writers and production crews. Read the full story on AI’s dramatic impact on China’s short drama industry.
