Winter Olympics: No snow, no problems… yet

The Beijing Games use almost 100% artificial snow, as climate change threatens to change winter sports forever.

Organizers of the 2022 Winter Olympics, which officially opened on Friday, have been using dozens of snow generators and hundreds of snowblowers to create 1.2 million cubic meters of powder (or about 42.4 million cubic feet).

The Games in Beijing will mark the first time athletes will compete almost entirely on artificial snow, according to a report from London’s Loughbough University.

That’ll likely become the norm as climate change continues, according to the report’s findings, «starting with lower-altitude slopes and raising pressure and costs on higher-[altitude] resorts.»

But generating fake snow has a high environmental cost, the authors say. «Even if powered by renewables, a huge amount of energy is needed which is both costly and can be a significant drain on water resources.»

And winter athletes say the artificial turf is less safe.

«Artificial snow is icier, therefore faster and more dangerous,» Estonian biathlete Johanna Taliharm told the Associated Press in January. «It also hurts more if you fall outside of the course when there is no fluffy snowbank, but a rocky and muddy hard ground.»

Team USA cross-country coach Chris Grover said landing in it «can feel like falling on concrete.»

Not everyone is critical of the fake stuff. Australian snowboarder Matt Cox, who’s making his Olympic debut at Beijing, told Reuters that «with the cold temps here, it’s dreamy snow.»

Artificial snow is more of a tightly packed frozen slush, made from water droplets that are broken up by a high-pressure pump and then crystalize into frozen flakes.

The International Olympic Committee maintains that artificial snow is used regularly at International Ski Federation competitions «and does not make the courses more dangerous.»

«To the contrary, it creates a more consistent surface from the top to bottom — or start to finish — of a course,» an IOC spokesperson told CNET. «The iciness and density of the surface is dependent on the needs of the given competition and the preparation of the course, not on the source of the snow.»

Most ski and snowboarding events at the Beijing Games will take place in Zhangjiakou, about 110 miles northwest of Beijing, including freestyle, cross-country, ski jumping and biathlon. Skating and several additional snow events are being held at the Capital Indoor Stadium in central Beijing.

Bobsled, luge and Alpine skiing events will be held in Yanqing, a mountainous area about 45 miles from downtown Beijing that’s rich in water resources, according to the IOC. Water supplies for the Olympic venues there will come from the nearby Foyukou Reservoir.

The IOC says that the electricity used to make the snow is from renewable wind and solar energy sources. In addition, water-conservation efforts have been instituted, including snow farming — preserving and relocating previous accumulation — and harvesting melted snow in retaining lakes at the end of the season.

According to the committee, water usage related to snow sports for the Games won’t impact nearby citizens’ consumption or agriculture needs.

«The regions where the snow-sport events will be held are constantly very cold,» the IOC representative said. «This allows a very efficient snow production and does not require the constant reproduction of snow, like in many ski resorts elsewhere in the world where the temperature fluctuations lead to a regular melting of the snow during a season.»

However, another recent study found that, by the year 2080, only one of the past 21 Winter Olympic hosts will still have sufficient winter conditions for the Games.

The ideal conditions for making artificial snow are a «wet-bulb temperature» of about 20 degrees Fahrenheit, representing a combination of the actual temperature and the amount of moisture in the air. But the 2026 Winter Games are slated to be held in Milan, where temperatures rarely dip that low.

The 2022 Winter Olympics in Beijing opened on Feb. 4 and will run until Feb. 20.

You’ll Soon Be Able to Buy Walmart Products Through ChatGPT

OpenAI’s chatbot already connects to Etsy and Shopify. Now you can buy bananas too.

OpenAI and Walmart will soon offer shopping via AI through ChatGPT, the retail giant said in a press release on Tuesday.

While using ChatGPT’s Instant Checkout feature, customers can buy groceries, electronics or other essentials within the chatbot interface.

Walmart has its own AI assistant in its app named Sparky. With Sparky, customers can ask questions about products and get summaries of reviews to find the best item.

«For many years now, e-commerce shopping experiences have consisted of a search bar and a long list of item responses. That is about to change,» Walmart CEO Doug McMillon said in a statement. «There is a native AI experience coming that is multi-media, personalized and contextual. We are running towards that more enjoyable and convenient future with Sparky and through partnerships including this important step with OpenAI.»

When asked for comment, Walmart referred to its press release. Walmart also said it wouldn’t discuss the financial terms of the agreement at this time.

«We’re excited to partner with Walmart to make everyday purchases a little simpler. It’s just one way AI will help people every day under our work together,» OpenAI CEO Sam Altman said in a press release.

OpenAI referred to Walmart’s press release when asked for comment.

The latest deal with Walmart comes as OpenAI tries to make ChatGPT an all-in-one shopping experience. AI chatbots are increasingly being used as vehicles for online shopping. They can synthesize reviews from across the internet and give people direct answers to shopping questions. Already, ChatGPT connects with Etsy and Shopify with its Instant Checkout feature, allowing people to buy directly. OpenAI also added more shopping features in ChatGPT Search earlier this year.

OpenAI Will Loosen ChatGPT’s Mental Health Guardrails and Allow Erotica for Adult Users

Sam Altman said the company will ease limits for adults after rolling out age verification.

ChatGPT is treading cautiously right now, but the chatbot may become more risqué by the end of the year.

In recent weeks, the generative AI chatbot has been operating under somewhat stringent limitations, as OpenAI tried to address concerns that it was not handling sensitive mental health issues well. But CEO Sam Altman said in a post on X Tuesday that the company would ease some of those restrictions because it’s «been able to mitigate the serious mental health issues.»

Though Altman didn’t elaborate on what tools are being used to address the problem, OpenAI recently announced new parental controls in ChatGPT.

CNET reached out to OpenAI for details, but the company did not immediately respond to a request for comment. (Disclosure: Ziff Davis, CNET’s parent company, in April filed a lawsuit against OpenAI, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.)

Other changes are also expected. Altman said the company could allow «erotica» for verified adult users as it implements an «age-gating» system, or age-restricted content, in December. The mature content is part of the company’s «treat adult users like adults» principle, Altman said.

Altman’s post also announced a new version of ChatGPT in the next few weeks, with a personality that behaves more like the company’s GPT-4o model. Chatbot users had complained after the company replaced 4o with the impersonal GPT-5 earlier this year, saying the new version lacked the engaging and fun personality of previous chatbot models.

«If you want your ChatGPT to respond in a very human-like way, or use a ton of emoji, or act like a friend, ChatGPT should do it (but only if you want it, not because we are usage-maxxing),» Altman wrote.

After OpenAI was sued by parents who alleged ChatGPT contributed to their teen son’s suicide, the company imposed an array of new restrictions and changes, including parental controls, alerts for risky behavior and a teen-friendly version of the chatbot. In the summer, OpenAI implemented break reminders that encourage people to occasionally stop chatting with the bot.

On Tuesday, the company also announced the creation of a council of experts on AI and well-being, including some with expertise in psychology and human behavior.

This comes as lawmakers and regulators are ringing the alarm on the risks AI tools pose to people, especially children. On Monday, California Governor Gavin Newsom signed new restrictions on AI companion chatbots into law. Last month, the Federal Trade Commission launched an investigation into several AI companies, including OpenAI.
