Xi Jinping announced China's new climate targets personally, a positive gesture, but the targets brought little clarity on China’s future emission pathway. Targeting a 7-10% emission reduction by 2035 from an undefined "peak level" undersells China's current clean energy boom.

Important leaders declaration just released by the heads of the most climate vulnerable countries here in New York: cvfv20.org/as-world-hur...

I know I'll take flak for this, but the principle - if not the execution - is sound. Modular reactors can enable the decarbonisation of parts of the economy that are otherwise hard to reach. But tying their development to the US? That's less sound. www.theguardian.com/business/202...

Is it too late to stop climate change, or do we still have reasons for hope? To launch Season Two, @marklynas.bsky.social talks with @hannahritchie.bsky.social, Deputy Editor of Our World in Data and author of Clearing the Air: The hopeful guide to solving climate change in 50 questions.

I love that @marklynas.bsky.social named his pod Saving the World From Bad Ideas. We took a stab at it; you might not like what we had to say but hear us out!

80 years on from the horror of Hiroshima should splitting the atom be seen as an environmental menace or asset? @BBCRareEarth @marklynas.bsky.social, Prof Tim Mousseau, Dr Fiona Rayment. The picture is from 1995 when I visited Hiroshimaon the 50th anniversary

Exciting episode of Saving the World from Bad Ideas releasing tomorrow, all about Rewilding. Is rewilding just about wolves & wilderness vs farmers &rural communities, or something much more hopeful @marklynas.bsky.social is joined by Rebecca Wrigley, Chief Executive of @rewildingbritain.org.uk.

I'll be speaking about my new book at the Cuckmere Wildlife Festival on the English south coast tomorrow morning. Tickets here: www.eventbrite.co.uk/e/cuckmere-w...

'I should have taken methane more seriously in fighting climate change,' admits Carl Pope from the Sierra Club in a self-serving NYT op-ed. Strange how he forgets to note that the Sierra Club took $25 million from the gas industry in 2007-10. Maybe that's why the Sierra Club didn't fight gas... 🤔

This is such a critical issue - and yet it's ignored by virtually everyone.

I sat down with @marklynas.bsky.social to talk climate science and policy, and a little about trans athletes Have a listen, ask me any Qs www.weplanet.org/podcast/epis...

Hurricanes. Floods. Fires. Tornadoes. Are extreme weather disasters getting worse because of climate change? Not according to Roger Pielke Jr, who has got himself cancelled by climate activists despite sticking to the IPCC line on extreme weather. Latest podcast: www.weplanet.org/podcast/epis...

Five reasons why the threat of nuclear war should be at the top of everyone's agenda: bookoftheday.nextbigideaclub.com/p/six-minute...

Just one person can start a nuclear war - Donald Trump - and no-one can stop him. www.washingtonpost.com/opinions/int...

As a Cold War kid, I'm constantly astounded by the fact that anyone ever thought climate change might be a bigger deal than nuclear war. And I say this as someone who's doing climate economics as a job.

It's nearly www.cuckmerewildlifefestival.com time! A repost would be lovely. @davegoulson.bsky.social @charliebingham.bsky.social @sophiepavs.bsky.social @katebradbury.bsky.social @hedgehoghugh.bsky.social @marklynas.bsky.social

In this week's podcast: the shocking story of how anti-nuclear ideology within Germany’s Green Party has led to the dismantling of 12.5 GW of clean energy capacity, just when Europe needs it most. Taking on the bad idea of the Energiewende: Noah Rettberg. www.weplanet.org/podcast/epis...

Most people think of the international ocean as a lifeless void. But actually it's the planet's last great wilderness, covering 43% of the globe's surface and is the biggest carbon sink, hosting vast multitudes of life. Time to protect it forever, before it's too late. www.nature.com/articles/d41...

As I've written before, nuclear conflict is now the most pressing existential threat we face. www.washingtonpost.com/opinions/int...

This is what happens when a country gets rid of its nuclear plants and replaces them with intermittent renewables at a grid scale - more coal: www.reuters.com/business/ene...

This is actually the epilogue from my book, extracted in Geographical magazine. A trip to Hiroshima past Mount Fuji, some karaoke and oysters, memories of 6 August 1945, and a dream of a world without nuclear weapons. geographical.co.uk/news/hope-an...

Bad Idea #11 "No such as planetary boundaries" with Johan Rockström In our latest podcast episode, @marklynas.bsky.social spoke with Johan Rockström, one of the world’s leading Earth system scientists & co-architect of the planetary boundaries framework.

The good news is that if we annihilate ourselves in a nuclear war, we will have answered the Fermi paradox, albeit in a rather negative way. My opinion piece in today's @newscientist www.newscientist.com/article/mg26...

My podcast guest this week challenges the bad idea that 'everyone hates nuclear' - and she's even written a book on the subject, profiling the nascent pro-nuclear grassroots citizens' movement. Meet star US writer Rebecca Tuhus-Dubrow... www.weplanet.org/podcast/epis...

In case you were wondering, Russia now has 1,700 nuclear warheads on active deployment. I'm sure it'll all be fine. thebulletin.org/premium/2025...

youtu.be/9WeTgNTjxPg?... Another great EP in this excellent "Saving the world from bad ideas" podcast series from @marklynas.bsky.social @weplanetint.bsky.social - Cynthia Scharf @cfg-thinktank.bsky.social delves in to the highly nuanced SRM skyscape

Germany's opposition to nuclear energy has been a major barrier to EU efforts to phase-out fossil fuels. The new German government's openness to nuclear energy will help accelerate the clean energy transition across the EU & globally.

Review of new book "Six Minutes to Winter" by @marklynas.bsky.social: "My generation of millennials was the first to spend their childhoods in relative innocence, largely free from warnings of nuclear apocalypse...The threat never went away."

In this otherwise reasonable review of my book Six Minutes to Winter, Max Hastings prefers 'mutually assured destruction' (MAD) to my "naive... Green Party solution" of getting rid of nuclear weapons permanently. MAD, Max - the clue is in the name! www.thetimes.com/culture/book...

The day of the war dawns like any other. There is no warning, and across New York people are beginning their daily routines. No air raid sirens wail and no early-warning messages flash. Outside an inner-city school, a group of 10-year-old girls wait to cross the road. lithub.com/mushroom-clo...

@marklynas.bsky.social on what would happen in the first few hours of nuclear war (and perhaps more importantly, how to prevent nuclear war in the first place).

Wonderful and expansive review of my book Six Minutes to Winter by @jamesrobins.bsky.social in the @washingtonpost.com. "Two options remain: deterrence or annihilation. How long do we have before the former gives way to the latter?" washingtonpost.com/books/2025/0...

"Annihilation is unthinkable. It is not nearly as unthinkable as allowing our present suspension to continue...These weapons are the worst thing humans have made, the worst we could ever make." My debut in the @washingtonpost.com on @marklynas.bsky.social's urgent new book

We're six minutes from Armageddon. Is today the day? www.bloomsbury.com/uk/six-minut...

In this urgent and wide-ranging conversation, @marklynas.bsky.social is joined by leading climate scientist and nuclear winter expert @alanrobock.bsky.social to confront one of the most dangerous myths of our time: that nuclear weapons keep us safe. Watch or listen now: www.weplanet.org/podcast

It seems sadly fitting that two nuclear-armed powers are on the brink of war on the day I release my book on how to avoid nuclear war - a 'small' war between India/Pakistan (each have 150ish nukes) would devastate civilisation and kills 100s of millions. www.bloomsbury.com/uk/six-minut...

Should we bring wolves back to the United Kingdom? I say yes, wolf expert Luigi Boitani says... to find out, listen to my latest 'Saving the World from Bad Ideas' podcast out today. This week's 'bad idea' - we can't co-exist with wolves (hint!) www.weplanet.org/podcast/epis...

Just in case you thought there was still time to save the Arctic, along comes my new podcast episode with Dr Julienne Stroeve to disabuse you. Sorry everyone. They can't all be hopeful. www.weplanet.org/podcast/epis...

Like a stopped clock, Trump can occasionally be right about something. This could be a key moment for the global nuclear renaissance, as World Bank backing will be key to allow major clean energy investments in the Global South. Germany is now be out of the way too. www.devex.com/news/is-this...

Brilliant and truly scary article by @naomiaklein.bsky.social and @astra.bsky.social - essential reading for all of us concerned about this peculiar modern-day fascism which seems to be consuming and distorting politics across the world.

Can't wait to dig in! I completely accept the moral and intellectual case for veganism, but find it a struggle - so I can't wait for lab-grown meat to be fully available... www.theguardian.com/environment/...
