00:00Glaciers are some of our planet's oldest inhabitants, but during several icy periods throughout history, they covered much more of Earth's surface.
00:11Now scientists have found evidence of the oldest glacier ever in South Africa, and it's raising new questions about our planet's ice ages.
00:18What researchers found were rocks impregnated with oxygen isotopes, discovered under one of the world's biggest gold deposits.
00:24These glacial deposits were then dated in a lab, with researchers saying they're likely from around 2.9 billion years ago.
00:31And they say this could change the way geologists look at our planet's historical freezing periods.
00:35The researchers explained this new evidence could mean there was another previously undiscovered ice age for our planet.
00:41Experts have deduced there were likely two ice ages in the past, both taking place within the last 650 to 700 million years.
00:48This one would predate those substantially.
00:50They also admit that way back then the continent that is now South Africa could have been situated somewhere closer to the poles.
00:56Meaning no global cooling event, but rather it was simply located in a cooler spot on the planet.
01:02Of course, I hope the stronghold is not reliable.
01:04I hope they'll be able to have a universe of its own chcešt.' That's why I hope theatoreаний' ветvory was given a huge difference.
01:06Please try to take a very simple response to the meteorologist and the meteorologist and the meteorologist.
01:08How to launch the meteorologist?
01:10I hope the meteorologist has further direction of the meteorologist.
01:12I'm so glad to see you let the meteorologist now on the meteorologist's right now.
01:13After this, we're going to see you soon, and hopefully the meteorologist's radio has a huge story,
01:14Here's one of the meteorologist.
01:15Thank you for the meteorologist.
01:16And we speak to you for the meteorologist about the meteorologist.
01:17I'm so glad to see you later.
01:18So thank you for the meteorologist.
