An extended bonus episode of the podcast, where we learn more about proposals to slow the rate of ice loss in Greenland - and if it works, in Antarctica - using a local form of geoengineering.
Host Rowan Hooper speaks to glaciologist John Moore and environmental social scientist Ilona Mettiäinen, both from the University of Lapland in Finland.
They discuss ... Show More

New genome of ancient human; 95% of us have a dormant virus that causes disease; Formula E cars faster than F1; Bill Bryson joins the pod!
Episode 332
For only the second time, the genome of an ancient Denisovan has been sequenced - thanks to the discovery of a 200,000-year-old tooth found in a Siberian cave. This ancient member of the human family has long been a mystery, so this genome is being described as a bom ... Show More

La géoingénierie solaire doit-elle être utilisée pour refroidir la Terre ?
<p>Les dernières décisions prises par la COP 26, en novembre dernier, pour limiter le réchauffement climatique de la planète ont paru insuffisantes à beaucoup d'observateurs. Aussi de nombreux projets, basés sur le concept de la géo-ingéniérie, voient-ils le jour pour tenter de r ... Show More

How to cool the planet with a fake volcano
When volcanoes erupt, they spray particles into the atmosphere that cool the planet for a bit. As we get closer and closer to truly catastrophic global warming, more and more scientists are wondering whether a similar approach, called solar geoengineering, could be necessary. If ... Show More
