What's for dinner?

On a planet wracked by rising seas, disappearing biodiversity, and hotter temperatures, that's a tough question to answer.

The way we produce, eat and waste food is one of the largest drivers of climate change globally, with food production responsible for a whopping one-third of greenhouse gas emissions. It's also the primary driver of biodiversity loss, with agriculture alone threatening 86% of species at risk of extinction.

At the same time, rising temperatures, heatwaves, droughts and floods, changes in rainfall patterns and other extreme events affect agriculture more than any other sector.

Scientists have found that limiting climate change will be impossible without big changes to how the world eats. But this does not have to be a downward spiral. We can reverse the negative relationship between food systems and climate change and turn it into a positive one.

That's why the future of food is on the menu in this episode of our It's Possible podcast.

We sat down with three experts to get a taste of what transforming the food system looks like:

• Peter McGuinness, CEO, Impossible Foods
• Esnath Divasoni, Agriculture Trainer, CAMFED
• Earlene Cruz, Founder and Executive Director of Kitchen Connection Alliance

With the UN Climate Change Conference COP27 set to begin in just a few days, this episode of our It's Possible podcast sets out to answer three key questions about the climate emergency: how did we get here, what does it mean and what can we do to change course?

The first half of the podcast explores the latest science and explains why the world is in a climate emergency. The second half of the podcast focuses on what needs to happen to avert this crisis and limit warming to 1.5 degrees Celsius to avoid the worst impacts of climate change.

We sat down with two of the world's leading experts on climate science and policy:

• Johan Rockström, Director, Potsdam Institute for Climate Impact Research
• Rachel Kyte, Dean, The Fletcher School at Tufts University

Thirty years ago last month, the text of the United Nations Framework Convention on Climate Change was adopted.

This was a significant milestone because it solidified a collective commitment from countries around the world to tackle climate change, together. It was a recognition that climate change was a global problem that required a global solution.

In this episode of our It's Possible podcast, we reflect on the past, present and future of global efforts to address climate change.

We sat down with three guests:

• Clover Hogan, Founding Executive Director of Force of Nature
• Richard Kinley, Former Deputy Executive Secretary of UN Climate Change
• Ovais Sarmad, Current Deputy Executive Secretary of UN Climate Change

Together, we look back at 30 years of intergovernmental negotiations on climate change. The conversation is wide-ranging and touches on various topics ranging from what the public understanding of – and concern about – climate change was like in 1992 to the dramatic rise of young people calling for climate action today. The conversation also centres around where we stand in global efforts to tackle climate change and what needs to happen next to ensure we can limit warming to 1.5 degrees Celsius.
