Greenland’s Huge Meltwater Waterfalls Generate Massive Hydropower

New research finds that the huge ice sheet is melting both from the top and bottom.

The surface of the Greenland ice sheet is melting, creating a network of ephemeral rivers and waterfalls that scientists say produces more hydropower than the collective output of the 10 largest hydroelectric stations on the planet.

It’s part of a brutal feedback loop brought on by climate change that could hasten the rise in sea levels around the world.

In summer, an increasing amount of the frozen surface melts, forming lakes and streams that rapidly make their way to the bottom of the ice sheet — traveling downward as much as a full kilometer — by rushing through cracks and large fractures. An international team of researchers set out to measure how much energy was created by this process.

«There’s a lot of gravitational energy stored in the water that forms on the surface, and when it falls, the energy has to go somewhere,» Cambridge University professor Poul Christoffersen explained in a statement.

Unfortunately, that energy is being converted to heat at the base of the ice sheet, leading to high rates of melting both on the top and bottom of the sheet.

The team used a kind of radar to measure the amount of melting and found rates often just as high on the bottom of the ice sheet as on the sun-splashed surface.

«The heat generated by the falling water is melting the ice from the bottom up, and the melt rate we are reporting is completely unprecedented,» Christoffersen said.

The study is published in the latest issue of the Proceedings of the National Academy of Sciences.

The researchers calculate up to 82 million cubic meters of water fell from the surface to the base of Store Glacier on the Greenland Ice Sheet each day during the summer of 2014. They estimate that water falling to the bottom of the sheet produces more hydropower during summer than the world’s top 10 hydroelectric generating stations combined.

«Given what we are witnessing at the high latitudes in terms of climate change, this form of hydropower could easily double or triple, and we’re still not even including these numbers when we estimate the ice sheet’s contribution to sea level rise,» Christoffersen said.

The Greenland Ice Sheet is already the largest single contributor to global sea level rise.

It’s too bad there’s no practical way to capture this hidden hydropower, as all that clean energy could help reduce the emissions that are actually accelerating its creation.

Stuck in a Coffee Rut? ChatGPT Can Now Plan Your Next Starbucks Order

Don’t be surprised if the chatbot suggests mixing espresso with lemonade.

If you like getting your daily cup of coffee from Starbucks, you’ll now be able to consult with ChatGPT for your next beverage. Starbucks said on Wednesday that a new Starbucks app in ChatGPT, now in beta, will help you figure out your next order based on your mood or craving in the moment.

Although you won’t be able to order your Starbucks coffee directly through the ChatGPT app, it will suggest drinks and menu items you may enjoy, then direct you to the Starbucks app or website to complete your order.

OpenAI has added a host of other apps you can interact with in ChatGPT since announcing the functionality last year. You can do everything from browsing home listings to designing playlists without leaving the chatbot interface.

You’ll be able to use prompts like, «@Starbucks, I want something bright to start my morning,» or upload an image to describe your mood and location. Once the menu suggestion appears in ChatGPT, you can start the order through the chatbot and then complete it in the Starbucks app or online.

Paul Riedel, senior vice president of digital and loyalty at Starbucks, said in a statement that Starbucks noticed customers weren’t always starting off by looking at the menu. «They’re starting with a feeling,» he said. «We wanted to meet customers right in that moment of inspiration and make it easier than ever to find a drink that fits.»

Starbucks said interacting with ChatGPT lets you personalize your order more and discover menu options you never considered before.

(Disclosure: Ziff Davis, CNET’s parent company, in 2025 filed a lawsuit against OpenAI, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.)

When I tried out the new feature, I asked it about the oddest beverage combinations you can get at Starbucks. One interesting combo ChatGPT came up with was espresso with lemonade. The AI described another drink as «basically liquid dessert soup,» if that’s more up your alley.
