Coastal engineer Jose Borrero describes how the phenomenon of drawdown, where the sea retreats from the shore, would have warned people that the impending arrival of the 2004 Indian Ocean tsunami.
The extreme pressure and temperatures in Saturn's lower atmosphere means the surface is bombarded by a type of rain formed of diamonds.
Jupiter's 'great red spot' is a huge storm that has raged for hundreds of years, while the usually calm Saturn can suddenly erupt in storms more violent than anything in the solar system.
Mars has an extremely low atmospheric pressure leading to dust storms that cover the entire planet for months - and 'dust devils' that are a kilometre high.
Explains the impact of extreme atmospheric pressure on temperature and how greenhouse gasses have created hellish conditions on Venus.
Our weather is extraordinary, from bowling ball sized hailstones to twisting tornadoes, but even the most extreme weather witnessed on Earth cannot compare to the weather on the other planets in our solar system, or even planets millions of light-years away, across the universe. Visiting state of the art laboratories and using amazing CGI images, this documentary will recreate the weather on these planets and illustrate worlds that not even the most creative science fiction writers could imagine.
A team of experts ventures back into Mexico's giant crystal cave. Described as Superman's fortress, the cave is as deadly as it is beautiful. But could it lead to another, more spectacular cave?
National park ranger Melinda Wilson takes Ernie Dingo on a controlled burn in UluruKata Tjuta National Park with members of the Anangu people from Mutitjulu.
Toxinologist Jamie Seymour teaches Ernie Dingo how to handle the most venomous fish on the planet, the stone fish, and handfeeds the most venomous snail, the cone snail.
Far from the city and past the port, sandy beaches, coral reefs and murky mangroves are home to an array of fascinating creatures. Take a journey across the waters to discover the surprising world of Singapore's wild islands.
Astronaut Scott Kelly spent a year living on the International Space Station testing human limits for space travel while his identical twin, retired astronaut Mark Kelly, was monitored here on Earth. In the Kelly brothers, NASA has a near-perfect, two person sample group for biomedical research. This is the story of what it takes to spend a year in space and then, using what NASA has learned from the brothers, what it means for humanity as we journey to Mars and beyond.
Thanks to NASA's ground-breaking Kepler mission, astronomers believe there are over 20 billion alien worlds with liquid water and therefore the potential for life.
Clouds and precipitation trapped by the Andean summits have now given way to complete deserts: the Nazca and Pisco Deserts, considered to be some of the driest places on earth. Cyril is joined by scientific journalist Emmanuelle Grundmann. Together they discover an oasis that is home to one of the most amazing trees in the world, the huarango.
In June 1783, on the Volcanic island of Iceland, a 17-milewide split appeared in the ground, triggering a disaster of gigantic proportions. Within one week more lava would pour onto the earths surface than from any other eruption in recorded history, instantly smothering all life in its path. The real problem however, was the deadly cloud of volcanic gases that had begun to accumulate; over eight months, more that 122 million tons of sulphur dioxide would spew out of the massive fissure, bringing death to hundreds of thousands of people across Europe. The Killer cloud wiped out more than a quarter of Iceland's population and three quarters of it's life stock, before it drifted across the North Atlantic to Britain, bringing prolonged devastation and suffering. Europe was smothered by a sulphurous, dry smog and in England, an uncommon gloom descended. The bizarre blue fog hovered for weeks. Crops withered, leaves were bleached and vegetation died. Millions of people were struck down with severe and often fatal bronchitis and asthma, while others suffered blinding headaches and partial loss of sight. The fallout was catastrophic and long lasting. Water and food supplies became contaminated. The toxic gases altered weather patterns, causing massive crop failure and the greatest famine in Iceland's history. Across Europe, death rates soared. That summer was the hottest ever recorded, whilst the following winter was the coldest. No other eruption before or since has caused such dramatic climate changes. The testimonies of those that lived and died during this massive natural disaster survives, in the form of diaries, letters and eye witness accounts., that offer us a unique insite into its effects on contemporary life.
