A long, cold and snowy winter is finally coming to an end. Just after dawn during a nocturnal unattended sound recording in an old forest. Black grouse is on the leks, and the voices of overflying Whooper swans can be heard. Chaffinches are migrating, and the local Willow tits have begun singing. Black and Great Spotted woodpeckers are drumming, but Ravens steal she show acoustically. Feels good to be alive.

Into the old-growth forest – spring advancing, woodpeckers and Raven come alive

The work is in two movements - Fraying and Prolonged. The first presents a sonic object that gradually disintegrates. The second reframes this object and slows it down, so that the process of decay is frozen, and the object appears almost immortal. The work grew out of reflections on 1 Corinthians 15 and Jiang Zhi's Love Letters (2014). In Jiang Zhi's photographs, flowers are on fire, but are not harmed by the flames.

Last episode, we talked about how we got to where we are now with climate change, but do we even know what’s going on with climate change right now? In this episode we’ll talk about what tipping points we’re approaching, how and why we’re still struggling to gain momentum toward action on climate change, and what difference it would make if carbon dioxide was a brown smelly substance.

To figure all of this out, we talked to a mathematician, Emily Shuckburgh, an engineer Hugh Hunt and a psychologist, Sander van der Linden. 

Along the way, we discuss solutions like geoengineering, creating a fake news ‘vaccine’ and opportunities for businesses to be more transparent about how their activities contribute to climate change. If you’re curious to find out more specific ideas about how we can build a greener future, check out Cambridge Zero’s Green Recovery Report here: https://www.zero.cam.ac.uk/green-recovery-report
