Tencent is one of China’s biggest tech companies, running the popular Chinese messaging app WeChat and the world’s largest video game vendor. Now, it’s also an up-and-coming force in the field of carbon removal. Xu Hao, the vice president of Sustainable Social Value at Tencent, oversees two of those initiatives: the Carbon Neutrality Lab and CarbonX. He sits down with Sherrell Dorsey, host of the “TED Tech” podcast, to talk about how megacorporation can help advance the climate movement. He also explores the current state of carbon removal technology and how Tencent’s video games are becoming an unlikely source of climate education for hundreds of thousands of people. 

This is episode three of a four-part series airing this month on TED Tech, where host and climate tech journalist Sherrell Dorsey speaks with climate leaders on the technology sparking a greener, more equitable future.

The environmental impact of AI is a growing concern. In this episode, Sherrell sits down with Juan M. Lavista Ferres, the Chief Scientist and Lab Director of Microsoft’s AI for Good Research Lab, to discuss his work in using AI for conservation and sustainability.

Today, we’re featuring an episode from NPR’s science podcast Short Wave. In it, host Regina G. Barber talks to computer scientist Ilia Shumailov about maybe the buzziest topic around: AI. I’m sure you know AI models like OpenAI's ChatGPT are trained on millions of examples of human-written text. Nowadays, a lot of content on the Internet is written by these generative AI models. That means that AI models trained now may consume their own synthetic content and suffer the consequences. What's the harm? Find out with this episode of Short Wave.

Artificial intelligence could cost many of us our careers — but that doesn’t mean we should stop its development, says journalist Megan J. McArdle. As she watches AI encroach on her own craft, she shares a fresh take on the 19th-century Luddites, who tried to destroy machines that would upend their trade. Looking back, McArdle reframes today’s fears with a poignant question: If we halt progress to protect the present, what might we be stealing from the future? After the talk, Sherrell highlights how AI might not be replacing human jobs---but creating new ones.

This is the surprising story of how Texas – rich in oil and gas – became America's biggest producer of wind energy. For our first episode, Ryan and Anjali talk with Pat Wood, once George W. Bush’s right hand man and head of Texas's Public Utility Commission, to uncover the innovative approach that turned Texas into a renewable energy powerhouse. It’s a story about what could get done before partisan politics got in the way of good climate policy, and it shows that economic incentives for consumers, government, and companies can play a huge role in supercharging clean energy.

As the line between the physical and digital worlds blur, so does the line between real-world and virtual sports. Reframing our understanding of competition, data-driven technologist James Hodge explains how far esports (like virtual Formula 1 race car driving) have come in replicating the conditions of physical sports, making elite competition more accessible than ever before. "This really is the new era for play -- and it's open to everyone," he says.

This week, the TED Audio Collective is releasing a bunch of great episodes about sports, in celebration of the launch of a new podcast: Good Sport with Jody Avirgan. It’s a show that takes sports seriously, as the best way to understand humans and our world. Check it out wherever you’re listening to this.
