Science In Action Folgen

Category 5 hurricane Otis, which devastated Acapulco, was supercharged by global warming; hurricane expert Kerry Emanual tells Science in Action. Also, Brazilian ecologist Erika Berenguer has witnessed the destruction caused by the prolonged drought in Amazonia, where the rivers are drying up and the forest is burning. And, climate scientists now say there is less time than previously thought to avoid further dangerous warming. Two climate scientists, Chris Smith and Norman Loeb, break the bad news - that the climate is more sensitive to greenhouse gases than forecasts have used.Presenter: Roland Pease Producer: Ella Hubber Editor: Martin Smith Production co-ordinator: Jana Bennett-Holesworth (Photo: A woman sits amongst the damage after Hurricane Otis.

Fear that the highly infectious variant of avian influenza, H5N1, would reach the Antarctic region and put isolated bird populations at risk has finally come to fruition as the first birds on Bird Island in the Atlantic Ocean have come down with the devastating illness. Science manager of the island, Ashley Bennison, explains the situation. Then, from one extreme climate to another - mummified mice have been found on the summit of volcanoes across the Andes, raising questions as to the capacity for vertebrates to survive in extreme conditions. Kevin Langergraber has been studying the Ngogo chimpanzee community in Uganda for over 20 years. Now, Kevin and colleague Brian Wood tell us how this group are experiencing something thought to be unique amongst humans (and some whales): menopause. And, how geophysicist Amir Kahn used seismic activity on Mars to understand what the core of our neighbouring planet is made of.

Accelerating seismic tremors are raising concerns for the thousands of people living atop a volcanic hot spot close to Naples, Italy. Volcanologist Alessandro Pino has been keeping a watchful eye on the developing situation. We stay in Naples where, almost 2000 years ago, the eruption of Mount Vesuvius buried Pompeii, including thousands of scrolls turned to charcoal by the immense heat. This hasn’t stopped people from trying to read the scrolls, destroying hundreds in the process. Now, computer scientist Brent Seales has deployed AI and papyrologists worldwide to decipher the burnt text. And from ancient scrolls to rainforest soundscapes, ecologist Zuzana Buřivalová has also been using AI to untangle the vast array of life heard in forests, old and new, as a tool to measure biodiversity.
