Scientists have found microbes frozen deep in the Antarctic ice sheets, in conditions very similar to the red planet's surface. Could life exist on Mars, in suspended animation? Physics - Universe - Learning Points. In 2001, a frozen...

In a remote corner of Siberia, climate change is having a visible impact. Vast expanses of soil, frozen for tens of thousands of years has started to thaw; and the process could dramatically increase the rate of global warming. The...

In our journey through the terrestrial biomes, we've covered rainforest, desert, grassland, and shrubland. Now let's take a look at deciduous forest, evergreen forest, and tundra. Where are these located? What sorts of organisms live...

Why did the US military dig a tunnel in the Alaskan tundra? What is the tunnel used for now?

As seawater temperatures rise, the Arctic ice cap has been shrinking. From 2003 to 2010, records show Arctic ice melting rapidly. This year it shrank by 27,000 square miles from its record 2007 low to 1.5 million square miles, the lowest...

Researchers have discovered a lake in Alaska that is bubbling due to methane emissions.

In Siberia’s thawing tundra, huge craters are being punched out of the Earth’s crust from below — by huge explosions. Scientists suspect that global warming is the culprit.

Researchers from the University of Alaska at Fairbanks (UAF) have identified tens of thousands of methane seeps in areas along the coast of Alaska and Greenland. Some experts believe the escape of large quantities of previously frozen...

A study conducted by Russian scientists in collaboration with Princeton University found 300 prehistoric worms in Yakutia, one of the coldest regions of Russia.

In 2018, NASA will intensify its focus on one of the most critical but remote parts of our changing planet with the launch of two new satellite missions and an array of airborne campaigns.

GRACE-FO and ICESat-2 will use...

It has been said that the frozen parts of our planet, also known as the cryosphere, may be the proverbial 'canary in the coal mine' when it comes to climate change. This video shows some of the most dramatic fluctuations to our...

The cryosphere consists of those parts of the Earth's surface where water is found in solid form, including areas of snow, sea ice, glaciers, permafrost, ice sheets, and icebergs. This animation portrays changes in the cryosphere...

For centuries, a massive store of carbon has been locked underground in the Arctic's permanently frozen soil known as permafrost. As Earth's climate continues to warm, that carbon has begun to leach into the atmosphere, the...

Bubbles, bubbles, and more bubbles, in a steady stream. Many lakes in the boreal regions of Alaska are emitting methane, the product of decomposing organic matter left over from the Ice Age.



Thawing permafrost has caused...

Because of a warming atmosphere, permafrost -- the frozen ground that covers the top of the world -- has been thawing rapidly over the last three decades. But there is cause for concern beyond the far north, because the carbon...

This program begins by explaining how scientists have learned that Earth’s climate has changed many times over billions of years and that Earth’s climate is...

Ecosystems and biomes takes students on a journey around the globe to tropical rain forests, deserts and the ocean. Live footage and colorful graphics teach students about regions and climates, and explain the impact environments and...

The video explores the Arctic tundra biome, highlighting its similarities to deserts in terms of receiving little precipitation. Additionally, the video mentions the Alpine tundra found on mountaintops, which shares similarities with the...

The climate, animals, and plant life vary greatly in the different parts of the world. Students explore how wildlife and the environment work together in harmony. By viewing the program and engaging in activities, viewers will learn to...
