This astounding documentary delves into the mysteries of the Tunguska event – one of the largest cosmic disasters in the history of civilisation. At 7.15 am, on 30th June 1908, a giant fireball, as bright the sun, exploded in the sky over Tunguska in central Siberia. Its force was equivalent to twenty million tonnes of TNT, and a thousand times greater than that of the atomic bomb dropped on Hiroshima in 1945. An estimated sixty million trees were felled over an area of over two thousand square kilometres - an area over half the size of Rhode Island. If the explosion had occurred over London or Paris, hundreds of thousands of people would have been killed.

Climate change is among the world’s greatest challenges. As a small Caribbean island, Cuba is disproportionately affected by climate change through extreme weather events. Up to 10% of Cuban territory could be submerged by the end of the century, wiping out coastal towns, polluting water supplies, destroying agricultural lands and forcing one million people to relocate. Finding solutions is now essential. In this documentary, Dr Helen Yaffe goes to Cuba to find out about ‘Tarea Vida’ (Life Task), a long-term state plan to protect the population, environment and the economy from climate change. The Cuban approach combines environmental science, natural solutions and community participation in strategies for adaptation and mitigation. Produced by DaniFilms with Dr Helen Yaffe from the University of Glasgow for the COP26 conference in Glasgow.

At the border between Navarre and Aragon we find the moors known as the Bardenas Reales, characterized by the dust and the omnipresence of the northern wind. This is a portrait of a land, but also a journey through Pilar’s memories. It is a glance at the past but also the present, and about how everything has changed, for better or worse.

A look at how climate change affects our environment and what society can do to prevent the demise of endangered species, ecosystems, and native communities across the planet.

In the 1950s, a devastating fog descended on London and enveloped the capital for several days, leaving Londoners lost in their own streets in one of the UK's biggest peacetime catastrophes.

In September of 1938, a great storm rose up on the coast of West Africa and began making its way across the Atlantic Ocean. The National Weather Bureau learned about it from merchant ships at sea and predicted it would blow itself out at Cape Hatteras, North Carolina, as such storms usually did. Within 24 hours, the storm ripped into the New England shore with enough fury to set off seismographs in Sitka, Alaska. Traveling at a shocking 60 miles per hour - three times faster than most tropical storms - it was astonishingly swift and powerful, with peak wind gusts up to 186 mph. Over 600 people were killed, most by drowning. Another hundred were never found. Property damage was estimated at $400 million - over 8,000 homes were destroyed, 6,000 boats wrecked or damaged.

The storm of 1993 that ravaged the Eastern Seaboard was bigger than any since the 1800s. Most were expecting only more unseasonable warmth, and were caught off-guard by the hurricane winds, massive thunderstorms, and fierce blizzards. Meteorologists puzzled over bizarre reports from their computers. Late warnings went largely unheard. Video footage from Florida to Maine documents nature's savagery.
