When the creators of the popular science show with millions of YouTube subscribers comes the

Minute Earth podcast. Every episode of the show dives deep into a science question you might not

even know you had, but once you hear the answer, you'll want to share it with everyone you know.

Why do rivers curve? Why did the T-Rex have such tiny arms? And why do so many more kids need

glasses now than they used to? Spoiler alert, it isn't screen time.

Our team of scientists digs into the research and breaks it down into a short, entertaining

explanation, jam-packed with science facts and terrible puns.

Welcome to Cool Stuff Daily.

I'm Roger Rizzou. On today's episode, we're heading to the bottom of the world,

where scientists drilled through more than half a kilometer of Arctic ice, kept going into the bedrock below,

and brought up a 23 million-year-old climate time capsule. And we'll find out what they learned about Antarctica's past.

At a remote site called Crary Ice Rise, perched along the edge of the West Antarctic

ice sheet, near the Ross Ice Shelf, an international team of 29 scientists pulled off a record

breaking feat. First, they traveled roughly 700 kilometers, or about 435 miles from the nearest Antarctic

research stations to reach the site. For extra perspective, after drilling was complete,

the core had to be transported more than 1,100 kilometers or 680 miles across the Ross

ice shelf to Scott Base before being shipped to New Zealand for further study.

This wasn't a quick ice core poke.

Using a hot water drill, researchers board 523 kilometers or 1,715 to 1,716 feet through solid ice until they hit bedrock then they installed a geological drilling

platform and kept going another 228 meters or 748 feet into ancient rock and sediment the result

the longest sediment core ever drilled from beneath an ice sheet.
