Has 'net zero' created space for 'anything goes'? Scrutiny of the physical realities of airport expansion is needed. This decision undermines efforts to transition the energy system in line with UNFCCC; makes it harder, more costly, more inequitable. journals.sagepub.com/doi/10.1177/...

The UK has used less energy than almost anyone anticipated 20 years ago, but opportunities to act on this potential were largely missed, according to a new report published by @tyndallcentre.bsky.social. Paper features @aliceclimate.bsky.social and Dr Gaurav Gharde. doi.org/10.71535/483...

How can flying be less polluting? www.bbc.co.uk/sounds/play/... @aliceclimate.bsky.social and others discuss this seemingly un-solvable question in the latest episode of Rethink from BBC Radio 4.

I’ve been reflecting on my own input into the climate debate over the past 2 decades - a @tyndallcentre.bsky.social report coming soon 👀 - & reading this reinforces my own sense of sadness that messages about equity, sufficiency&need for demand-side transformation are still failing to cut through.

"The IMO has well and truly failed the most climate vulnerable" - a new blog about the latest development in tackling greenhouse gas emissions from shipping: theconversation.com/how-petrosta... Sadly an outcome completely at odds with stated ambitions & its 2023 strategy @uomscieng.bsky.social

Explore the sessions at our upcoming Critical Decade for Climate Action Conference, this September 📜 Full agenda and registration info: tyndall.ac.uk/events/criti... Speakers include @goneri76.bsky.social @neiladger.bsky.social @aliceclimate.bsky.social #Tyndall25UEA

"The solution is simple but not easy" @jingyi-climate.bsky.social discusses the opportunity of using warm water from disused coal mines to heat homes in areas hit hard with job losses when mines were closed. She addresses barriers to implementation. theconversation.com/how-mine-wat...

This is a big week for the shipping sector & the IMO; a chance for a whole global sector to agree a carbon price. While waiting on news, have a listen to @theconversation.com's weekly podcast focused on why short-term decarbonisation - thinking 'beyond fuels' - is essential pod.link/1550643487/e...

🛳️ The UN shipping agency is on the cusp of introducing binding regulations to phase out fossil fuel use in global shipping — with the world’s first-ever global emissions levy on the table. 🗣️ "It would be an absolute game-changer." ✍️ Take a look at the full story: www.cnbc.com/2025/04/09/c...

Did you know 3% of global emissions come from shipping? This is more than the 2.5% from aviation 🚢✈️ 💬 Professor @aliceclimate.bsky.social was interviewed by @uk.theconversation.com to explore how shipping emissions can be reduced to meet Paris agreement targets. theconversation.com/a-google-map...

It's all going on this week at the IMO in discussions on decarbonising shipping; issues include aligning intensity with absolute targets & the thorny issue of putting a price on carbon theconversation.com/at-a-pivotal... @simonclimate.bsky.social @uniofmanchester.bsky.social @uomscieng.bsky.social

Some interesting shifts in language in the CCC's Seventh Carbon Budget report, compared to the Sixth. - the emphasis on UK "leadership" has almost gone ⬇️ - references to "justice/fairness" have plummeted by 85% ⬇️⬇️⬇️ - references to "households" have skyrocketed by 400% ⬆️⬆️⬆️ A short 🧵

statistic of the day: approving the expansion of Heathrow, Luton and Gatwick airports would wipe out ALL the benefits of the government’s 2030 "clean power" target within five years of expanded operation, according to analysis by the New Economics Foundation (NEF) neweconomics.org/2025/01/airp....

Well this captures it unfortunately ..."we are not even moving in the right direction, let alone at the required pace".

There isn’t enough ‘sustainable’ aviation fuel to make a dent in our emissions – and there won’t be for years, says @benpurvis42.bsky.social #climatecrisis theconversation.com/there-isnt-e...

Interesting paper showing how safeguarding planetary boundaries such as freshwater or land system change reduces BECCS potential to close to zero - in contrast to huge potentials generated by IAMs.Picture would be even worse for low conversion efficiency biofuels for transport.

Lesson for us all: Climate warming has been particularly bad in Switzerland, where “a group of farmers turned to the Swiss courts to force the government to do more to act on climate change before their farms become unviable.” www.nature.com/articles/d41...

Encouraging growth in a sector with such limited opportunity for decarbonisation at present not only ends up cancelling out CO2 reductions made in other sectors, but also flies directly against the 'equity' framing enshrined in the Paris Climate Agreement journals.sagepub.com/doi/full/10....

What would Heathrow third runway mean for carbon emissions, air pollution, and noise? More, more, more ... Analysis by me #climatecrisis www.theguardian.com/environment/...

And if this isn't sufficiently worrying, don't forget atmospheric CO2 concentrations over the past 800,000 years ... www.bbc.co.uk/news/article...

⚓ The international #shipping sector must shift emphasis to short-term energy efficiency and #emission reduction over fuel and 2050 targets in order to play its part in meeting Paris Agreement goals, argue @simonclimate.bsky.social, @aliceclimate.bsky.social & Jonathan Kohler Read more⬇️

1/2 We are thinking about maritime decarbonisation but beyond alternative fuels, to deliver CO2 cuts in the near-term. See here for why we think a new emphasis on innovation focused on *existing* ships/maritime infrastructure is essential tinyurl.com/BeyondFuel @imohq.bsky.social

New article – Met Office: Atmospheric CO2 rise now exceeding IPCC 1.5C pathways ✍️ By @richardabetts.bsky.social from @metoffice.bsky.social Read here ⬇️ https://buff.ly/4hjNiHm

This seems like good news but isnt it problematic to characterise science that illustrates woefully inadequate mitigation efforts, as ‘doomsday’ stories?To constructively engage stakeholders with the scale of what’s needed, we need honesty about where we are(as per @richardabetts.bsky.social report)

This post makes a huge "Gotcha" out of an uncaught error on a webpage. The idea that a comms person writing the web page used old data is totally believable. The word "static", simply means that the webpage was written manually, and isn't connected dynamically to a data source. 1/3

We reduce emissions to reduce long-term damage from climate change. We adapt to reduce near-term damage from climate change. New open access paper discussing how emissions mitigation and climate adaptation are complementary approaches to reducing climate damage: www.nature.com/articles/s43...

As climate change increases the risk of dry conditions and fire weather, fires across western NAm are bigger, more dangerous, and burning greater area. It’s the difference between accidentally dropping a match into a pile of green, wet wood versus dropping it into a stack of bone dry kindling.

Interesting article highlighting poor foresight & the problem of assuming LNG is a suitable transition fuel for #ships; not so if the Paris Agreement is the goal. 'Green' ferry emits more CO2 than old diesel ship www.bbc.com/news/article... @globalmarhist.bsky.social @journalmaritime.bsky.social

How long does CO₂ have to be stored in #CarbonDioxideRemoval #CDR? At least 35 years? 100 years? Longer?🤔 In a new study, @hausfath.bsky.social, @retoknutti.bsky.social & I find that for #netzero CO₂, anything less than 1000 years is not enough to neutralize warming.🧵 www.nature.com/articles/s43...

Nice piece on what can happen when scientists go outside...

More than 90% of fossil fuel emissions occurred since my parents were born. Over 80% since I was born. Over 30% since my children were born. And well over 50% since the world agreed at the Rio Earth Summit to prevent dangerous climate change. And I thought: „At last!“

I've been following ICJ climate hearings (not an expert on law, happy to learn), but I can't believe what I'm seeing from countries that call themselves climate leaders. Their arguments in court tell a different story from their calls like "we're all in this together". enb.iisd.org/internationa...
