Conversations with scientists exploring science-based ways to protect the future of our planet, our children, and other creatures that share our World. We live on a planet in crisis. Scientists have warned us about the rapidly increasing dangers of climate change and destruction of the biosphere - specifically in the 1992, 2017 and 2019 World Scientists’ Warnings which were signed by 1,700; 15,000 and 11,000 scientists respectively when issued.

The growth of unsustainable industrialised agriculture is a key driver of climate change - how do we change course? Carol McKenna is Special Advisor to the Chief Executive of Compassion in World Farming and works to achieve systemic change towards regenerative agriculture. She is co-editor of Farming, Food and Nature: Respecting Animals, People and the Environment published by Earthscan in 2018.

Moderator Ed Gemmell, Managing Director, Scientists Warning Europe passionately believes that action to protect the climate is needed now based on the indisputable science. He sees awareness of the three Scientists Warnings and the fact they are signed by tens of thousands of scientists as vital in stimulating that action. After reading the first two warnings Ed sat outside the houses of parliament on 22 July 2019 and read 20,000 of the signatories’ names over the course of 14 hours while streaming live to Facebook. After undertaking his own ecological conversion Ed founded No Disposable Cup Day and Believers Action on Climate Change. He then stood in the 2019 General Election as an independent candidate with only one policy to reverse climate change. As a parish councillor Ed was instrumental in Hazlemere Parish Council making a Climate Emergency Declaration. Ed is a member of Friends of the Earth, a regular speaker, ex-army officer and city lawyer and owner of his own marketing business bringing with him a wide variety of skills to the role of Managing Director for Scientists Warning Europe.

This is the audio from a session held as part of the Planet in Crisis – Creating Action for COP26 global online summit. In November 2020, exactly one year before the official COP26 climate conference, Scientists Warning Europe organised this series of online Pre-COP events to raise awareness, push the conversation, show demand, and drive real action. Over 25 events were attended by more than 2,000 people from across the globe.

Scientists Warning Europe presents and promotes science endorsed solutions which will lead to a just transition for our World to a sustainable and equitable future. Learn more, sign up for updates, and support our work at
