Fire in the Sky reveals how researchers have gained new insight into the impact of the Northern Lights on infrastructure and animal behavior. The documentary explains why solar storms can be a danger to humanity with the power to damage satellites, stop air traffic, and paralyze power grids and telecommunications networks.

Northern Lights have fascinated and disturbed our ancestors for centuries. But they could also endanger our future

Climate change is making the weather increasingly unpredictable and volatile. Extreme weather events are on the increase: In a matter of minutes, hailstorms can destroy an entire year's harvests and flash floods can take lives and destroy homes. What are the causes of these extreme phenomena? And how bad could they become in future?

Thunderstorms, Hail and Heavy Rain

Hail, thunderstorms, flash floods: Why are these extreme weather events happening?

Extreme Weather Events

A quarter of all greenhouse gas emissions come from agriculture. Factory farming and extreme use of fertilizers and pesticides pollute our air, pollute our water and destroy our soil. Every year, 24 billion tons of fertile soil are lost worldwide. In Spain, two-thirds of the country is affected by desertification. But there are also soils further north that are similarly desolate. In this episode of Roots, science journalist Pierre Girard meets Remedios Arres in Andalusia and Johanna Häger in Brandenburg, the sandbox of Europe.

Fighting Desertification

What should Europe do about its damaged and depleted soil?

Roots

In France, in the Massif Central, Sarah Singla practices conservation agriculture based on three principles: minimal soil disturbance, permanent land cover and crop rotation. In Périgord, Benoît Le Baube also protects his fields by no longer plowing them. He also uses organic waste to fertilize the soil.

Sustainable Agriculture to the Rescue

In France, in the Massif Central, Sarah Singla practices conservation agriculture.

In this episode, we discover with the journalist Pierre Girard how cows can make the activity of a farm more respectful of nature and how sheep can improve cereal harvests. These unusual methods could offer a solution to agriculture's carbon emissions problem.

Climate-Killer Cows

In this episode, we discover with the journalist Pierre Girard how cows can make the activity of a farm more respectful of nature.

Biodiversity is good for the environment but also for our taste buds. In Alsace, a winegrower practices "complantation", the mixing of several grape varieties on the same plot to avoid pesticides. In southern Italy, Mario relies on the coexistence of plants and livestock to enrich the biodiversity of his fields and produce a mozzarella with a unique taste.

Resilient Biodiversity

Biodiversity is good for the environment but also for our taste buds.

The largest store of carbon besides the oceans is the soil. If only 0.4 percent more carbon could be put into the earth every year, the increase in greenhouse gas emissions would stop immediately. This is called carbon farming. But whether carbon goes into the soil or not is decided by agriculture. In this episode of Roots, science journalist Pierre Girard meets Félix Noblia in the Basque Country and Fabrice Desjours in Burgundy.Félix uses a special grazing system that actively stores carbon in the soil. Fabrice Desjours from Burgundy combines forgotten herbs, trees and plants to transform meadows into forest gardens where everything is edible.

Carbon Farming

If only 0.4 percent more carbon could be put into the earth every year, the increase in greenhouse gas emissions would stop immediately.

The planet's jet streams are being affected by rising temperatures in the Arctic. These streams are part of a wind system that circulates at high altitude around the Earth, and they have an influence on extreme weather events. Changes in them are bad news for life on Earth.

Winds of Change

To survive in the extreme environment of the desert, Corentin and Caroline will need a shelter to protect them from the blazing sun and house their various low-tech technology and food sources. They enlist the help of specialist engineers to design a bespoke cocoon using only biomaterials

Living with Biomaterials (5/5)

Corentin and Caroline need to build themselves a special shelter for their mission using only biomaterials.

The Biosphere Experiment - Making of

Corentin and Caroline explore cutting-edge low-tech solutions to meet their electricity and heating needs. Techniques that will enable them to power their independent lives in the desert for four months... and also to keep fit.
