In just one devastating month, Houston, Florida, and the Caribbean were changed forever. In summer 2017, three monster hurricanes swept in from the Atlantic one after another, shattering storm records and killing hundreds of people. First, Harvey brought catastrophic rain and flooding to Houston, causing $125 billion in damage. Less than two weeks later, Irma lashed the Caribbean with 185 mile per hour winds - and left the island of Barbuda uninhabitable. Hot on Irma's heels, Maria intensified from a Category 1 to a Category 5 hurricane in just 15 hours, then ravaged Puerto Rico and left millions of people without power. As the planet warms, are these superstorms the new normal? How well can we predict them? And with hurricane season just around the corner, does the U.S. need to prepare for the reality of climate refugees? NOVA takes you inside the 2017 superstorms and the cutting-edge research that will determine how well equipped we are to deal with hurricanes in the future.
Venture into the danger zone of two volcanic craters posing widely divergent threats. Hawaii's Kilauea is a shield volcano that threatens communities with its slow-but-relentless lava flow, while the Sumatran Sinabung is a stratovolcano delivering carnage via a sudden and explosive surge of superheated gas and rock.
Japan has more than 100 active volcanoes--two in particular may be on the verge of unleashing a devastating sequence of deadly eruptions and secondary earthquake activity. Join intrepid volcanologist Tom Pfeiffer's dangerous and exhilarating journey to the foot of these angry giants.
As part of the connecting landmass between North and South America, Mexico has long been at the center of a tectonic tug of war spanning millennia. The result is two of the world's largest, most active volcanoes--the rumbling Popocatepetl and the menacing Volcano De Colima--whose vengeful displays of wrath are increasing in frequency. Could a cataclysmic eruption be just around the corner?
Volcanologist Tom Pfeiffer and his team are embarking on their most daring adventure yet--visiting and photographing two remote Indonesian volcanoes, among the 20 most active in the world. Join a tense journey into the heart of one of nature's most dramatic and unpredictable natural phenomena, one that will test this experienced crew of scientists and native guides.
Disastrous hurricanes. Widespread droughts and wildfires. Withering heat. Extreme rainfall. It is hard not to conclude that something’s up with the weather and many scientists agree. It’s the result of the weather machine itself—our climate—changing, becoming hotter and more erratic. In this two-hour documentary, NOVA will cut through the confusion around climate change. Why do scientists overwhelmingly agree that our climate is changing, and that human activity is causing it? How and when will it affect us through the weather we experience? And what will it take to bend the trajectory of planetary warming toward more benign outcomes? Join scientists around the world on a quest to better understand the workings of the weather and climate machine we call Earth, and discover how we can be resilient—even thrive—in the face of enormous change.
Last century, earthquakes killed over one million, and it is predicted that this century might see ten times as many deaths. Yet when an earthquake strikes, it always takes people by surprise. So why hasn't science worked out how to predict when and where the next big quake is going to happen? This is the story of the men and women who chase earthquakes and try to understand this mysterious force of nature. Journeying to China's Sichuan Province, which still lies devastated by the earthquake that struck in May 2008, as well as the notorious San Andreas Fault in California, Horizon asks why science has so far fallen short of answering this fundamental question.
(PART 2) A team of experts and explorers venture into the Danakil desert in Northern Ethiopia to investigate the incredible geology of the area, and to find out how the people and their animals survive in the hottest place on earth.

In 1998, wildlife enthusiast and photographer Chris Packham had a remarkable encounter with the Orang Rimba, a tribe of hunter gatherers in the rainforests of Sumatra, Indonesia. It was the first time he had ever seen people living in perfect harmony with their environment. One photograph in particular that Chris took, a picture of a young tribal girl, has since become immensely important to him as a barometer of how we are treating our planet. In this real-life detective story, with no clues as to her identity or whereabouts other than his original photograph, Chris sets off to Sumatra 20 years on to try to find her; the girl in the picture. Chris's search is further complicated because her tribe is nomadic and often cover vast distances on foot, and since he was last there, millions of hectares of her rainforest habitat has been destroyed. Piecing together the clues, Chris discovers to his horror that the girl's close-knit group of Orang Rimba was attacked not long after he met them, and a number of them killed. But was the girl among them? Chris travels into the heart of Sumatra and tries to discover the girl's fate by meeting the men who pulled the murdered tribespeople's bodies out of the river. On his way, he discovers just how much of Sumatra's once pristine rainforests have been replaced by palm oil plantations, palm oil which is in around 50% of the products we buy in our supermarkets. Chris learns some uncomfortable truths about how we are all in some way connected to deforestation.

NOVA follows a team of volcano sleuths as they embark on a worldwide hunt for an elusive volcanic mega-eruption that plunged the medieval earth into a deep freeze. The mystery begins when archaeologists find a hastily dug mass grave of 4,000 men, women, and children in London. At first they assume it's a plague pit from the Black Death, but when they date the bones, they're a century too early. So what killed off these families? The chronicles of that time describe a run of wild weather that devastated crops and spread famine across Europe. NOVA's expert team looks for the signature of a volcanic eruption big enough to have blasted a huge cloud of ash and sulfuric acid into the atmosphere, which chilled the entire planet. From Greenland to Antarctica, the team finds telltale "fingerprints" in ice and soil layers until, finally, they narrow down the culprit to a smoldering crater on a remote Indonesian island. Nearly 750 years ago, this volcano's colossal explosion shot a million tons of rock and ash into the atmosphere. Across the globe, it turned summer into winter. What would happen if another such cataclysm struck again today?
Off Australia's northeast coast lies a wonder of the world, a living structure so big it can be seen from space, more intricate and complex than any city, and so diverse it hosts a third of all fish species in Australia. The Great Barrier Reef as we know it -- 8,000 years old and home to thousands of marine species -- is dying in our lifetime.
This feature documentary tells the story of the story of the pioneers who founded Greenpeace and defined the modern green movement. In 1971 a brave group of young activists set sail from Vancouver in an old fishing boat. Their mission: to stop Nixon's atomic bomb tests in Amchitka, a tiny island off the west coast of Alaska. It was from these humble but courageous beginnings that the global organisation that we now know as Greenpeace was born. Chronicling the fascinating untold story behind the modern environmental movement and with access to dramatic footage that has not been seen for over 40 years, this gripping new film tells the story of eco-hero Robert Hunter and how he, alongside a group of like-minded and idealistic young friends in the '70s, would be instrumental in altering the way we now look at the world and our place within it. These campaigning pioneers captured their daring and sometimes jaw-dropping actions on a range of film cameras and Greenpeace granted acclaimed director Jerry Rothwell access to this vivid archive to make his thrilling, sometimes terrifying film. Greenpeace was born in 1971 when a ragtag group of journalists, hippies, and scientists living in Vancouver tried to stop a US atomic test. Fortunately, they were media savvy from the beginning, capturing their seat-of-their pants activist adventures on film. The youthful energy is palpable in action-packed scenes, including one in which activists confront a Russian whaling ship in a tiny Zodiac dingy. Soon, though, idealism comes up against reality, compromise, human nature, and the complexities of managing a growing organization. This insightful film is also a vibrant, moving reflection about the ongoing struggle to balance the political and the personal.

Adventurer and journalist Simon Reeve heads to one of the most spectacular countries in the world - Colombia. For 50 years, Colombia has been in the grip of a brutal civil war that has killed more than 200,000 people and displaced seven million. But in late 2016, a peace deal was signed promising to end the conflict and finally bring peace to the country. In this hour-long documentary for the award-winning This World strand, Simon explores Colombia at a pivotal point in its history. He travels into the jungle and comes face to face with the guerrilla army FARC, which is now promising to lay down arms. In the Pacific coast city of Buenaventura, Simon finds out more about the fearsome right-wing paramilitary gangs who now dominate the cocaine trade. As the FARC abandon the countryside, there is a fear that these groups will only grow in power. Travelling in the countryside, Simon meets the coca farmers who are demanding government support to stop growing coca and stop the flow of money to criminal gangs. With land ownership, poverty and drugs at the heart of Colombia's problems, it is in the countryside that the country's precarious future will be decided.
As winter approaches, field teams are finishing up their science for the season. It's the last chance to obtain information for their research on the frozen continent. As most people are preparing to leave, a container ship is on its way in to supply food and materials to the skeleton crew that remains during the cold, dark winter months.
Science in Antarctica will shut down for the winter. Scott Base has plenty of logistics to manage in order to send teams out to finish their missions for the season. The USS Coast Guard crew is challenged by their aging ship as they try to finish cutting a channel in the ice before they escort the ship in. The Mt. Erebus team struggles to salvage as much data as they can before they go home.
In Antarctica both humans and animals do what it takes to adapt to and survive the harshest climate on earth. Our scientists focus their research in the icy waters to determine how climate change and human interaction have affected the marine ecosystem. Human life in the Antarctic can be put in danger when the technology it relies on fails.
The Mt. Erebus team has trouble landing at one of their sites and when they do their gear glitches from the cold. Meanwhile, the USS Coast Guard gets stranded from engine failure. Another team struggles to protect their 80,000 drone from a crash landing due to extreme wind. The Ross Ice Shelf Team digs themselves out after enduring a major storm and heads toward their target research spot.
Scientists deployed to Antarctica are accustomed to frigid temperatures, but few have experienced the condition one storm that is sweeping over Scott Base and the Ross Ice Shelf. Scott Base shuts down all missions and flights to and from western Antarctica have been cancelled; leaving them more isolated from the outside world than ever.
Six different teams of scientists arrive on the continent after years of planning. The continent is home to the coldest, windiest, driest conditions on the planet, and without Scott Base as their central hub, these teams wouldn't survive. Each team's results could have massive implications to better understanding how climate change is affecting life around the world.
We live in an age when technological innovation seems to be limitlessly soaring. But for all the satisfying speed with which our gadgets have improved, many of them share a frustrating weakness: the batteries. Though they have improved in last century, batteries remain finicky, bulky, expensive, toxic, and maddeningly short-lived. The quest is on for a “super battery,” and the stakes in this hunt are much higher than the phone in your pocket. With climate change looming, electric cars and renewable energy sources like wind and solar power could hold keys to a greener future...if we can engineer the perfect battery. Join host David Pogue as he explores the hidden world of energy storage, from the power—and danger—of the lithium-ion batteries we use today, to the bold innovations that could one day charge our world.
From the global perspective of space, this 2-hour special reveals the breathtaking extent of our influence, revealing how we’ve transformed our planet and produced an interconnected world of extraordinary complexity.

Four and a half billion years ago, the young Earth was a hellish place—a seething chaos of meteorite impacts, volcanoes belching noxious gases, and lightning flashing through a thin, torrid atmosphere. Then, in a process that has puzzled scientists for decades, life emerged. But how? NOVA joins mineralogist Robert Hazen as he journeys around the globe. From an ancient Moroccan market to the Australian Outback, he advances a startling and counterintuitive idea—that the rocks beneath our feet were not only essential to jump-starting life, but that microbial life helped give birth to hundreds of minerals we know and depend on today. It's a theory of the co-evolution of Earth and life that is reshaping the grand-narrative of our planet’s story.
California is on the brink of an apocalypse. The state faces a future of drought that will cost billions in lost farm revenue and thousands of jobs. But the challenges facing the state are not unique: All over the world, governments are struggling with bigger populations and a diminishing supply of freshwater. Innovators across the globe are seeking solutions in emergent technologies to prevent a planet-wide water crisis.
The semantics of the model I'm working from use common goods/common property/ common pool resources (resources used by multiple people) and common property regimes (the institutions or social arrangements between people, the property rights regarding common pool resources).

Surviving the bone-chilling cold, deadly blizzards and darkness of an Alaskan winter takes courage, cunning and remarkable endurance. In the raw beauty of windswept mountain peaks, icy tundra and snowbound forests, this is the story of the tough and resourceful characters that face up to the ultimate challenges of this untameable land.
No season brings more surprises than an Alaskan summer. It lures hummingbirds up from the tropics, exposes deserts in the Arctic and relies on parachuting firefighters to tackle forest fires in its vast wilderness. Summer is a narrow window of plenty, when the land is bathed in 24-hour sunlight - but in this land of extremes, you can have too much of a good thing.
As spring lights up the land, Alaska faces one of the greatest transformations on earth. Temperatures soar, and as the sun's rays hit the snow and ice, water, light and warmth return. Alaska's transition to spring may look magical, but for those animals emerging from a long winter's sleep, it's a time of intense competition, as everything is in a rush to cash in on Alaska's riches.
Professor Iain Stewart uncovers clues hidden within the New York skyline, the anatomy of American alligators and inside Bolivian silver mines, to reconstruct how North and South America were created. We call these two continents the New World, and in a geological sense they are indeed new worlds, torn from the heart of an ancient supercontinent - the Old World of Pangaea.
Professor Iain Stewart uncovers the mysterious history of Australia, and shows how Australia's journey as a continent has affected everything from Aboriginal history to modern day mining, and even the evolution of Australia's bizarre wildlife, like the koala.

Earthquakes have always been a terrifying phenomenon, and they’ve become more deadly as our cities have grown — with collapsing buildings posing one of the largest risks. But why do buildings collapse in an earthquake? And how can it be prevented? Vicki V. May explains the physics of why it is not the sturdiest buildings, but the smartest, that will remain standing.
On 26 April 1986, reactor number four at the Chernobyl Nuclear Power Plant blew up. Forty-eight hours later the entire area was evacuated. Over the following months there were stories of mass graves and dire warnings of thousands of deaths from radiation exposure.
We are all seeing rather less of the Sun. Scientists looking at five decades of sunlight measurements have reached the disturbing conclusion that the amount of solar energy reaching the Earth's surface has been gradually falling. Paradoxically, the decline in sunlight may mean that global warming is a far greater threat to society than previously thought.
Something weird seems to be happening to our weather - it appears to be getting more extreme. In the past few years we have shivered through two record-breaking cold winters and parts of the country have experienced intense droughts and torrential floods. It is a pattern that appears to be playing out across the globe. Hurricane chasers are recording bigger storms and in Texas, record-breaking rain has been followed by record-breaking drought. Horizon follows the scientists who are trying to understand what's been happening to our weather and investigates if these extremes are a taste of what is to come.
Six months after the explosions at the Fukushima nuclear plant and the release of radiation there, Professor Jim Al-Khalili sets out to discover whether nuclear power is safe. He begins in Japan, where he meets some of the tens of thousands of people who have been evacuated from the exclusion zone. He travels to an abandoned village just outside the zone to witness a nuclear clean-up operation.
For centuries we have dreamt of reaching the centre of the Earth. Now scientists are uncovering a bizarre and alien world that lies 4,000 miles beneath our feet, unlike anything we know on the surface. It is a planet buried within the planet we know, where storms rage within a sea of white-hot metal and a giant forest of crystals make up a metal core the size of the Moon.
Over the last few years, our weather in Britain has become more extreme. Last winter was the wettest ever recorded, as deadly storms battered the country for weeks on end. But previous winters have seen bitter lows of -22, as Britain was plunged into a deep freeze. What everyone wants to know now is: why is our weather getting more extreme, can we expect to see more of it in the future, and has it got anything to do with climate change?
In February 2013, a hole opened up beneath a home in Florida, and swallowed a man. Jeff Bush was asleep when a sinkhole opened up beneath his bedroom. Despite the efforts of his brother to rescue him, Jeff was never seen again and his body was never recovered. Professor Iain Stewart travels to Florida to try and understand what killed Jeff, and why the geology of this state makes it the sinkhole capital of the world.
Iain Stewart investigates a new and controversial energy rush for the natural gas found deep underground. Sometimes, this is right under the places people live in. Getting it out of the ground involves hydraulic fracturing - or fracking. Iain travels to America to find to find out what it is, why it is a potential game changer and what we can learn from the US experience. He meets some of the people who have become rich from fracking as well as the communities worried about the risks.
The last episode deals with the future of conservation. It begins by looking at previous efforts. The 'Save The Whales' campaign, which started in the 1960s, is seen to have had a limited effect, as whaling continues and fish stocks also decline.
The air around us is not just empty space; it is an integral part of the chemistry of life. Plants are made from carbon dioxide, nitrogen nourishes the soil and oxygen gives us the energy we need to keep our hearts pumping and our brains alive. But how did we come to understand what air is made of? How did we come to know that this invisible stuff around us contains anything at all?
Ice may be nothing more than frozen water but, as Iain explains, it holds extraordinary power. Descending 150m down a frozen waterfall, he sees a glacier in action from below and discovers why the huge Jacobshaven glacier is retreating, he shows how it shaped our past and may now threaten our future.
Iain travels into the stratosphere in a Cold War fighter, gets his eyebrows singed in Siberia and discovers why Argentina is one of the stormiest places on Earth. All to show why our atmosphere is unique and utterly crucial for life.
Volcanoes have a fearsome reputation. In reality, they are the most important force in the creation of the planet as we know it today. Iain abseils into a lava lake and cave dives in a cenote to show how the heat that fuels volcanoes also drives some of the most fundamental processes on the planet.
They form natural boundaries, dictate how we spread around the planet, create natural defenses, and control our weather. From the World War that began with a gunshot in the Balkans to the feuds of the Appalachians, mountains have also been flashpoints.
