(And other stories)

This week I'm going to talk about a range of issues including how older people are damaging the climate, why we're growing food in the wrong place, global action on biodiversity, news from the Antarctic, a call to more action following COP26, action on emissions and the rumoured reasons for the delay on the UK's energy strategy.

Today we're looking at the step beyond Net Zero: climate intervention or geo-engineering. Our interview guest says, "Geo-engineering in any form sounds like a terrible concept, until you peer carefully into the future and realise that not geo-engineering would likely prove worse."

Energy is always in the news. It's inextricably linked with emissions and the level or absence of emissions determines the outcome of the climate crisis. Nevertheless, it's time to talk about something else as well. OK, I did promise to tell you about space energy, so we'll look at that. I'm also going to look again at Deep Adaptation from Jem Bendell, at the pressures in the UK to reject Net Zero, news of the continuing weather crisis in Australia, Finland's new nuclear station (sorry - that's another energy story) and hydropower by truck (that's energy, too). And there's a fabulous city of the future planned for the desert.

The Wednesday Interview with Wayne Visser talking about the ideas in his new book. How complex organisations don't need to wait for leaders to achieve fundamental change. How change is happening already.

This week there's sustainability news about food, fuel, forests and floods in China. I look again at the IEA report that Sarah Cullen mentioned in Wednesday's interview. There's a dark side to solar farms, a pressure group intent on depressurisation and more dangers for bees. Can we summon a wartime spirit to save our economy and save the planet, and is mega finance group Blackrock walking the green walk or just talking the green talk?

The Wednesday Interview

Sarah Cullen, energy expert, joined me to talk about clean energy. We covered a number of controversial issues. For example, will Germany slow down the pace of decommissioning its nuclear plants in the face of a possible shortage of gas from Russia? We talked about citizens' assemblies, and how they might empower politicians to adopt policies that they wouldn't dare consider on their own. We spoke about the need to consider all energy options and to recognise that all have risks and about the IEA's Roadmap to Net Zero 2050.

Listen now to the full conversation, and all the other things we talked about.

This week's episode is about the latest IPCC report. You're probably already aware that it's pretty pessimistic. Will the warning be heeded this time? I'll talk also about the effect of the conflict in Ukraine on global energy prices and I've followed up the question from Sophie Jarvis about infrared heating.

Today I'm talking to Nick Spencer in Cambodia who is helping local people to survive and thrive while protecting wildlife and avoiding deforestation.
