Some might call sand coarse, rough and irritating, but there’s no denying that it’s used everywhere: from glass to asphalt, sand is a key ingredient for all sorts of materials in construction and technology. But this heavy reliance on...

Antarctica is a vast and dynamic place, but radar technologies -- from World War II-era film to state-of-the-art miniaturized sensors -- are enabling scientists to observe and understand changes beneath the continent's ice in...

Hank gets to the bottom of an exciting, and kinda weird, announcement from Russian scientists at the Vostok Research Station in Antarctica. Have they reached a 20-million-year old underground lake? Maybe! Is there a hoard of Nazi secrets...

Winter is upon us, and for many that includes snow! And although snowflakes are ice crystals that become flakes under the right conditions, they also have mysteries that can be less simple to explain!

Hank shares losses and finds this week, including a huge amount of Antarctic ice that’s lost for good, and 10 cool new species that are last year’s top finds.

These days it seems almost trivial to cool atoms down to near absolute zero temperatures in a lab, but what is the lowest possible naturally occurring air temperature on this planet?

Hidden beneath Greenland’s ice and powered by a nuclear reactor, Camp Century made for an interesting US military base. But life under the ice came with unique struggles; and although it wasn’t mainly constructed for science, the base...

The Greenland ice sheet is massive, mysterious -- and melting. Using advanced technology, scientists are revealing its secrets for the first time, and what they've found is amazing: hidden under the ice sheet is a vast aquifer that holds...

Rob Dunbar hunts for data on our climate from 12,000 years ago, finding clues inside ancient seabeds and corals and inside ice sheets. His work is vital in setting baselines for fixing our current climate -- and in tracking the rise of...

Hank brings you news from around the universe, including what you can't blame on global warming, why being unfaithful is hazardous to your health, and how to watch a particularly awesome spectacle coming to a sky near you.

Today we’re going to talk about glaciers. These behemoth globs of compressed ice and snow moving across the land created fertile soils and physical features while also serving as frozen time capsules. They recorded both Earth’s climatic...

For humans, being upside-down isn’t a comfy way to hang out for very long, but for these six animals, upside-down feels just right!

Hank talks about a few - maybe crazy, maybe reasonable - geoengineering schemes that some scientists have come up with in order to "fix" climate change, including designer clouds, ocean fertilization, and stratospheric shading with...

If all of Antarctica’s ice melted, our coastlines would be drastically altered. Fortunately, that’s not going to happen anytime soon, but new evidence suggests that West Antarctica - which holds around 5 METERS of sea level rise - is...

Science Kids Antarctica and the Melting Ice Shelf V1-0002

The melting of the Thwaites Glacier, driven by human-caused global warming, is contributing to rising sea levels. If the entire glacier were to melt, it could result in a...

The origin of Homo sapiens is in Africa. But at some point we began to leave and settle in other parts of the world. When did this happen, and why? What are the remains we have found that document this incredible journey? Let's take a look!

Antarctica is not like every other continent. Aside from its extreme cold and vast ice sheet, it's also the only major piece of land that has never had a human settlement rise up on it. And because of this, as it was explored in the...

ANTARCTICA ANTARTICA IS A STOREHOUSE OF EARTH HISTORY AND CONTAINS MANY CLUES ABOUT ITS POSSIBLE FUTURE. STUDYING SECTIONS OF ICE CORE GOING BACK 800,000 YEARS, SCIENTISTS AT THE BRITISH ANTARCTIC SURVEY HAVE COME TO SOME STARK...

Greenland:"To finish, we go to the surprising Island Country of Greenland. To admire some of the most incredible glaciers on earth. This land with 80% of ice has fantastic places to explore."

A “tipping point” is when a system, with just a small amount of additional energy, is pushed from one stable state to another suddenly and dramatically. This can be a chair falling backwards. Or it can be a major earth system collapsing....

For decades, Antarctic sea ice trends seemed to defy climate change, until…they didn’t. In just two years, Antarctica lost as much sea ice as the Arctic lost in three decades. Statistics say that the record low sea ice in 2023 was a 1 in...

Laser technology aboard aircraft has allowed scientists to measure the Greenland Ice Sheet, one of the largest bodies of ice in the world. Is it growing or shrinking? Earth Science - Human Impacts - Learning Points. NASA scientists...

This video provides an overview of the North Pole and the surrounding Arctic region, highlighting the characteristics of the ice pack and the impact of climate change. It discusses the thickness and movement of the ice and the increasing...
