Arctic sea ice is melting at record levels throwing global weather into chaos and contributing to extreme warming. There are three MAJOR climate systems that may be approaching their tipping points, and their future depends, in part, on...

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 V1-0004

I will take personal steps to reduce my carbon footprint by cutting down on flights, using public transportation or biking more often, and consuming products more mindfully,...

Science Kids Antarctica and the Melting Ice Shelf V1-0003

This video discusses the impact of rising sea levels on coastal and island communities around the world due to factors like population growth and climate change. It...

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 collapse of the Conger Ice Shelf in East Antarctica in 2022, the first of its kind in human history, highlighted the vulnerability of Antarctic ice to rising...

Howcast - If you’re still living in the Ice Age—that is, with a non-defrosting freezer—you’ll need these ancient skills.

Satellite images show how fast the Earth is changing due to things like melting glaciers, wildfires, dams, and growing cities. These changes can affect people’s lives, such as forcing them to move or losing access to water and land....

Racing cars are playing in the snow when they hear a kitten meowing. The kitten is stuck! With help from an excavator and bulldozer, they remove the snow and warm the kitten.

Aerogels are the world's lightest (least dense) solids. They are also excellent thermal insulators and have been used in numerous Mars missions and the Stardust comet particle-return mission. The focus of this video is silica aerogels,...

This video highlights the alarming effects of global warming on the Spellbard region of the Norwegian Arctic. It discusses the rapid changes occurring due to excessive carbon dioxide emissions, including the potential extinction of polar...

When something is as incredibly difficult to get to as Mercury, it is extremely tricky to study. Which is one of the reasons why in all of human history, there have only ever been 2 missions to Mercury, with just one more on the way....
