Cari snorkels in the beautiful Red Sea and then gets an even better look under the sea on an underwater dive. In the desert, she meets a Jordanian brother and sister, and the three have fun playing in the sand dunes. Cari learns about zaerb, a traditional food cooked under the sand, and is thrilled to discover she'll be camping in the desert overnight.

Warm seas in the Atlantic and Caribbean threaten a monster hurricane, and they deliver. A tropical cyclone forms near The Bahamas, aiming for Florida and the Gulf of Mexico, but it turns as it builds, putting the East Coast on alert. And as Hurricane Humberto forms, and grows to Category 3 status, its tight arc sends it directly toward the island of Bermuda. This is what our 1,000 cameras captured.

Yellowstone National Park is a spectacular landscape and a diverse habitat which supports an array of wildlife. But this serene habitat also holds a dark secret: it sits atop a super-volcano that could 'blow' at any minute. This episode follows the park's residents; the beavers, otters, elks and bison that are oblivious to this ticking time bomb, thriving in this land of extremes. Our narrator, esteemed naturalist Armstrong Wedgewood (actor Matt Lucas)...

Located on the west coast of Greenland, 150 miles north of the Arctic Circle, Greenland’s Ilulissat Icefjord is the sea mouth of Sermeq Kujalleq, one of the few glaciers through which the Greenland ice cap reaches the sea. Moving at a rate of approximately 60 feet per day, Sermeq Kujalleq is one of the fastest and most active glaciers in the world. It annually calves more than 8 cubic miles of ice—10% of the production of all Greenland calf ice...

Tropical cyclones devastate people, property, and infrastructure. This program outlines how cyclones are classified across the world and then examines the impact of Hurricane Matthew on the southeastern United States and Haiti in 2016. It compares the strategies that wealthy nations, like the U.S., employ to protect people and property to how the lack of resources in a poorer nation, like Haiti, leaves hurricane victims highly vulnerable to suffering...

Earth has got swirl. The air in the atmosphere swirls. The water in the ocean swirls. But what does it all have to do with weather and climate? To answer this, we’ll have to get a close-up on all that swirl. Don’t worry, being dizzy is fun! Topics include: Earth's Place in the Universe; Investigating Earth's Past; Restless Earth; Mountains, Volcanoes, and Earthquakes; Energetic Earth; Atmosphere and Oceans; and Earth Systems.

Where Montana kisses Canada lies a jewel of the US national park system. Glacier's million-acre wilderness is arguably America's most stunning natural environment, with 700 or so wetland areas and lakes, towering peaks, hundreds of waterfalls and - of course - two dozen glaciers. Called by Blackfeet Indians "the backbone of the world," this World Heritage Site straddles the US/Canadian border. Its glaciers carve and reveal prehistoric seas, faults,...

Located well above the Arctic Circle, the site includes the mountainous Wrangel Island (2,937 square miles), Herald Island (4 square miles) and surrounding waters. Wrangel was not glaciated during the Quaternary Ice Age, resulting in exceptionally high levels of biodiversity for this region. The island boasts the world’s largest population of Pacific walrus and the highest density of ancestral polar bear dens. It is a major feeding ground for the...
