Hurricane season runs from June to November. During these months, all three requirements for hurricanes to form are present. Storms form off the coast of Africa and travel on currents of warm ocean water. Also, the wind patterns alter the location of the jet stream. Part of the "Seasonal Science" series.

Travel to the Namib Desert and discover the key characters of some of the ingenious adaptations that allow animals to thrive in this harsh environment. The secret to life in this unique ecosystem lies in the distribution of airborne water and food sources. Part of the "Nature's Microworlds" series.
In this episode, host Steve Backshall examines how the reintroduction of the wolf at Yellowstone has set off a cascade of events that have reverberated through the food chain. The beaver population has increased, while the number of coyotes have sharply declined. The pronghorn antelope, one of North America's most endangered species, has also reaped the benefits of the reappearance of the wolf. Part of the "Nature's Mircroworld" series.
Canada's coastal forest is part of an ancient forest system of redwood, spruce, and cedar trees. It is also home to some of the largest aggregations of top predators in North America. The trees of this forest are huge, and forest productivity here rivals even some of the world's biggest tropical rain forests. Part of the "Nature's Microworlds" series.
Glaciers are one of the main driving forces affecting Earth's climate and landscape. These massive sheets of ice are constantly moving and changing, and warming temperatures are causing most glaciers to recede. Located in some of the most inhospitable areas of the planet, scientists are venturing to glaciers to study them and looking for clues from past and present changes in climate. Part of the "Glacier Series."
The Galapagos Islands are home to a myriad of bizarre and unique creatures that are endemic to these islands, but how did they get here? What is the key to these extraordinary islands that allows them to thrive? In this episode, host Steve Backshall reveals the secret to life here. Part of the "Nature's Microworlds" series.
The city of Ann Arbor, Michigan has turned to engineering research to tackle an issue facing many cities: aging stormwater infrastructure during a time of tight budgets, growing populations, and more extreme weather. With support from the National Science Foundation, civil and environmental engineer Branko Kerkez and a team at the University of Michigan are building a new generation of smart and connected stormwater systems. Part of the "Science Nation" series.
During a class about seasons, Speedy falls asleep and dreams that he and Shawn arrive at Rusty's lab. Rusty has invented an unusual device called the "Seasons Changer." While delivering the device, the two friends accidentally activate it and learn about each season. Part of the "Shawn and Team" series.
In this episode, host Steve Backshall lifts the lid on an incredible world of intricate relationships and unexpected hardships in the Amazon rain forest. He explores the way that the jungle's inhabitants interact and reveals a hidden secret that might just be what keeps the whole place alive. Part of the "Nature's Microworlds" series.
Journey to the Scottish Highlands, home to some of the most iconic British wildlife. Since the Ice Age, the Highland landscape has undergone a transformation from dense forest to large areas of open space, and the wildlife there needs both of these habitats to thrive. Part of the "Nature's Microworlds" series.
Journey through the marine ecosystem of Monterey Bay, California, where a giant kelp forest hosts one of the most diverse marine ecologies in the world. The secret to the balance of this ecosystem is a keystone species: the sea otter. Part of the "Nature's Microworlds" series.
Host Steve Backshall examines what is by far the largest ecosystem on the planet: the deep sea. It contains some of the most extraordinary and bizarre life forms. There is even life on the deep seabed, where armies of sea urchins, giant wood louse, and deep sea crabs feed from a thick layer of sediment. Part of the "Nature's Microworlds" series.
In this episode, host Steve Backshall conducts an investigation into what makes the Okavango such a diverse place. The Okavango Delta is a vast inland river delta in northern Botswana. It's known for its sprawling grassy plains, which flood seasonally, becoming a lush animal habitat. Part of the "Nature's Microworlds" series.
How could a body of water as big as the Mediterranean Sea just disappear? It would take decades and more than a 1,000 research studies to even start to figure out all the possible causes of one of the greatest vanishing acts in Earth’s history. Part of the "Eons" series.
Earth’s climate is changing in a big way, and it’s because there's more carbon dioxide in the atmosphere than at any point in human history. But Earth’s climate has changed before. How are scientists studying the impact of human behavior on climate? They are collecting ice cores and analyzing the tiny bubbles of ancient atmosphere trapped in the cores. Part of the "It's Okay to Be Smart" series.
The Center for Advanced Forestry Systems is using forestry science and collaborations among universities, industry, and the government to make commercially grown forests more productive and sustainable. With support from the National Science Foundation (NSF), research teams at Virginia Tech, North Carolina State University, and the University of Washington have teamed up through the center to study how new slow-release fertilizers could improve growth and not destroy waterways. Part of the National Science Foundation Series “Science Nation.”
The Darién Gap is a remote tropical forest that has been home to indigenous people for thousands of years. As pressures from outside human development encroach on the forest, these communities are protecting their land using a cutting-edge tool: drones. Through a partnership with a nonprofit organization, the Rainforest Foundation, they map their community boundaries to secure land titles, create sustainable land-use plans, and monitor their forests against logging and ranching.
A team of researchers from the University of Utah is perfectly situated to study rock arches. With support from the National Science Foundation, geologist Jeff Moore and his team are pioneering a new method of structural health monitoring to keep tabs on the structural integrity of geological landmarks. The researchers have discovered that each arch has its own "voice." The arches naturally vibrate, like a guitar string, with its own distinct resonant frequency. The team's research has important implications for the conservation and management of these natural structures. Part of the "Science Nation" series.
As shown on the History Channel. Why do we have ice ages and when is the next one due? Chart the progress of different ice ages through the history of our planet, from Snowball Earth hundreds of millions of years ago to the recent ice ages. As the Earth circles the sun, its orbit changes slightly and so does it angle of rotation. When the right wobble in our rotation combines with the right orbit, the Earth is, and will again be, plunged into an ice age--but maybe not for a few thousand years.
For over a century, tens of millions of visitors have marveled at the natural beauty of Yellowstone National Park, home to the largest concentration of geysers in the world, including the iconic Old Faithful. Visitors may not realize it, but Yellowstone is situated directly above one of the largest volcanic systems on Earth-a supervolcano. For the past two million years, this volcano has erupted roughly every 600,000 years. The last major eruption, which produced a caldera that stretches over 1,500 square miles across the park-two-thirds the size of Prince Edward Island-occurred 640,000 years ago. So, is it overdue for another eruption?
