The oceans are very important in climate change because they take in almost 90% of the heat trapped by greenhouse gases and a lot of carbon dioxide. This makes the oceans warmer and more acidic, which has led to record-low sea ice,...

What is Greenland, and why is it called that if it’s mostly covered in ice? In this video, we explore the basics of Greenland—its location, history, geography, and why it matters today. Learn about the world’s largest island, how it was...

This video explores the fascinating world of deserts, highlighting how plants and animals have adapted to survive in these harsh environments. It covers different types of deserts, from hot and dry to cold and icy, and discusses the...

Greenland is a spectacle to behold! It's almost entirely covered in ice, yet there are some "green" areas. Still, the largest island in the world is home to only about 56,000 people making it one of the least densely populated regions of...

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 paradigm shift in geology occurred with the development of plate tectonics, a theory which allows us to understand so much regarding what we see and experience on Earth's surface. How did this come to be? Who is Alfred Wegener? Who is...

Warming temperatures in the Arctic are changing the tundra from a landscape dominated by grasses to one increasingly dominated by woody shrubs. In addition to affecting the habitat of local wildlife such as caribou and musk...

NASA says it plans to launch an advanced laser instrument which would be used to monitor our planet's melting polar ice.

Antarctic ice sheet melting could increase sea levels by over five meters by the year 3000 if current warming trends continue.

Ask and ye shall receive! After a long, long hiatus to do a bit more reputable history for almost a year, it’s time to delve back into the crank files and check out more theories about visitors to the Americas before Columbus. Today we...

This video explores the significance of Greenland's massive inland ice sheet and how it serves as a laboratory for studying the history of our planet. Scientists are studying the ice sheet to understand how quickly it's melting and how...
