Welcome to Belém, where the world (with some notable exceptions) has gathered to talk about saving the Amazon as if it weren’t already on fire.

Cataloguing the chaos leading up to COP30 Ben Cooke of The Times. His team’s reporting makes clear why the mood isn’t exactly jubilant: the clean-power alliance with zero members, the rainforest pledges with little progress, and the renewed swagger of fossil petrostates.

Even potential bright spots, like the Tropical Forest Forever Facility announced last week, were somewhat dimmed by the spectacle of UK prime minister Keir Starmer reversing an earlier decision not to go to COP, only to make the trip to then announce his government wouldn’t be part of the hoped-for signature initiative out of this event.

We chat with Ben about all of that and more.

Shipping is one of those things that’s just supposed to work. Post-Titanic, we created a set of rules that currently are looked after by the International Maritime Organization (IMO), which successfully removed much of the drama from shipping — so successful that Britain’s “Shipping Forecast” is now soothing ASMR for bedtime listening.

But last month at the IMO in London, what should have been a procedural meeting on decarbonising shipping turned into something far messier. According to a Financial Times investigation, U.S. officials didn’t just lobby against a global carbon levy on shipping — they allegedly threatened, intimidated and black-mailed delegates from smaller nations.

Developing-country delegates said they were warned their ships would face higher U.S. port fees, their officials denied visas, and their trade punished if they didn’t abandon support for the Net Zero Framework the IMO had endorsed only six months earlier. “It was like dealing with the Mob,” one diplomat told the FT.

In the end, it worked. The deal — the world’s first carbon-pricing mechanism for global shipping — was postponed for a year. The IMO, normally the most technocratic of international bodies, was left “in a state of complete shock.”

For the uninitiated this may sound arcane. But shipping matters. Roughly 90 % of global trade moves by sea; the sector accounts for about 3 % of global CO₂ emissions — more than Germany — and until now has been largely outside the reach of meaningful climate regulation.

The Net Zero Framework was meant to change that. It had already been provisionally agreed by a majority of countries in April. But by October, something changed. Countries like China, India, Panama, Liberia — and even Greece and Cyprus, who broke with the EU line — suddenly voted to adjourn. news.wickedproblems.uk

And the shift didn’t come from nowhere: it came from pressure. From a U.S. administration that now treats climate policy as an existential threat to American interests.

🎧 Who we spoke to

• Carly Hicks (Chief Strategy & Impact Officer, Opportunity Green) explains how the IMO had once seemed one of the last genuinely global forums where climate ambition could meet technical reality — until the process was capsized by politics.
• Ariane Morrissey (Senior Editor, Ship.Energy) was in the building as the talks imploded, describing a surreal scene where delegates who came to discuss fuel standards found themselves under threats of sanctions and visa bans.
• Professor Tristan Smith (University College London) gave the longer-view: this is less a failure of climate tech than a warning shot about the fragility of multilateralism itself. He argues the US may have bought time — but may also have triggered the rise of regional regulation. The EU’s carbon-trading scheme now covers shipping; Singapore and Japan are exploring carbon levies. The patchwork world is arriving faster than the ships can adjust.

🎵 Outro music: “Sailing By” (1963) layered with a long-wave “Shipping Forecast” transmission — that calm voice reading “Viking, North Utsire, South Utsire…”

In this episode of Wicked Problems, host Richard Delevan welcomes Dave Jones and Kostantsa Rangelova from the energy think tank, EMBER. They've spent the past year spreading the good news about the impressive advancements in solar and battery technology, particularly focusing on global trends and potential game-changers in regions such as Africa and Mexico. Despite solar only contributing to 6.6% of Mexico’s electricity, EMBER simulations indicate it could rise to 90% with optimal efficiency. In some spots like Muscat, Las Vegas, or Mexico City, almost all their power, day and night, can now be generated from just solar + battery.

The discussion covers the rapid progress and cost reductions in battery technology, the promising shift towards 24/7 solar power, the surge of solar adoption in Africa, and the significant untapped potential in Mexico. The episode highlights the transformative impact of solar and battery technologies on global energy landscapes and emphasizes the urgent need for effective policies to accelerate this transition.

Dr. Lorna Gold is the executive director of the Laudato Sì Movement, which was inspired by the late Pope Francis’ 2015 letter. That document, considered pretty radical for the leader of the Catholic Church to issue at the time, was credited by former Irish president Mary Robinson and others with influencing the Paris Agreement - and you can hear echoes of it as recently as the advisory opinion issued this summer by the International Court of Justice.

On its 10th anniversary, Francis’ successor Pope Leo will lead the Raising Hope Conference, 1-3 October in Rome - but also available via livestream - talking about the relevance of its ideas for the situation we’re in now. More than a “Catholic” thing, it will feature people as diverse as Brazil’s climate minister Marina Silva (in the runup to COP30), climate scientist Dr.

Katharine Hayhoe, Bill McKibben, Arnold Schwarzenegger, Tuvalu climate minister Dr Maina Talia, Bianca Pitt of SHE Changes Climate, Fossil Fuel Non-Proliferation Treaty president Kumi Naidoo, and more. Somehow, Lorna was able to take a break from organising the event to speak to us.

Lorna earned a PhD in economic geography from Glasgow University and author of Climate Generation: Awakening to our Childrens’ Future.

It’s a great chat and we think you’ll enjoy it.

Will Nigel Farage's Reform party succeed in demonising climate action? Or will adaptation change the conversation? Are the Tories cooked? And does Gaza create an opening big enough for Jeremy Corbyn's new party to cut into Labour support?

Richard Delevan talks to More in Common's Ed Hodgson about Shattered Britain, how Britain's "Tribes" will shape the future - and why you need to understand them if effective climate communicators are going to win.
