Attached is a suggestion I made several years ago. It would need to be part of a broader package, including eliminating first & business class, & ensuring even the first flight incurs the same tax & carbon costs as other fuels do. Aviation remains heavily dependent on its highly privileged status

I genuinely hope to be wrong, but I suspect @rory-stewart.bsky.social & @alastaircampbell2.bsky.social are in the top fraction of 1% of hi-emitters & so cling to future tech salvations & the allure of weak but well crafted legislation. The challenges we face raise profound questions of "moral code".

As Labour open their annual conference, I’d be interested if anyone can share Ministers/MPs’ views on further expanding UK airport capacity; expansion that's incompatible with UK climate commitments, not to mention increased volume & frequency of aviation noise! climateuncensored.com/gatwick-expa...

... Integrated Assessment Models need to be abandoned. They can’t be fixed; adding more maths, social science, or data won’t turn astrology into science. We are in a climate and ecological emergency, not an incremental political game.

From my Tyndall talk: Structurally locked-in emissions dominate discourse; discretionary emissions – especially from the middle and upper classes – are ignored. Even now, questioning these lifestyles remains taboo, despite their hugely disproportionate impact and capacity for rapid change.

@catherinemitchell.bsky.social closes her #Tyndall25UEA talk with the attached slide: to paraphrase, academics wanting to make a real world difference should stick with integrity & ditch political expediency (&near-term prestige -my addition). Good to hear, but the decadal timeframe is a problem?

Good to see @goneri76.bsky.social refer to “sufficiency”. I see this as the key framework for rapidly curtailing emissions, while low carbon tech substitute for oil/gas norms. But sufficiency needs to focus on discretionary emissions &fairness to be effective (&help avoid opposition).

@goneri76.bsky.social points to current global low point in political engagement on climate change. In my view all the more reason for climate academics to stand up to make their evidence heard - we need to go well beyond just academic papers & conferences.

Really good to see a break from the usual approach.
If we focus on Paris 1.5-2°C rather than net-zero 2050 similar work urgently needs undertaking for 2030-40, with a key focus on what actual emission reductions can we achieve between this evening & 2030. See: climateuncensored.com/irelands-cli...

In 2012 @IEA.org CEO Fatih Birol was deeply concerned about climate change (attached). Today, half a trillion tonnes of fossil fuel emissions later, he’s parroting “drill baby drill”. Has the allure of sycophancy to the POTUS sent his integrity to the four winds or have the laws of physics changed?

After six weeks working with my always inspiring @cemusuppsala.bsky.social colleagues, just got on the train heading back to the UK. Uppsala (Sweden) to New Mills (UK, nr.Manchester) in around 26hrs (via Stockholm-Hamburg night train). The EU really need to support a network of quality night trains.

Was sent this (originally in Private Eye) - though I think it may be a paraphrase of the IPCC Working Group III conclusions😉
An additional concern for me is that the nonsense this piece parodies can and already is being shoe-horned into ‘net’ zero. We need to escape the allure of the ‘net’ lie.

2/2. The attached table,based on carbon budgets from Lamboll et al www.nature.com/articles/s41... updated to the start of 2025,shows how Paris 1.5-2°C is far more challenging than is politically acceptable; hence lots of spurious/speculative/dodgy mitigation nonsense to reconcile the irreconcilable.

My view has long been we need to separate mitigation into non-substitutable commitments; see attached tweet-based summary.
This would limit bean-counter scams by the unscrupulous &pull the rug from under the oil/gas majors' net-zero claims at the same time as exploring for new fossil fuel reserves.

Just to note, the "well below 2°C" budget is for an 83% chance of not exceeding 2°C.
As for the budgets, updated to start from January 2025.
For a 50% chance of not exceeding 1.5°C it is ~170GtCO2
For an 83% chance of not exceeding 2°C it is ~575GtCO2

Returning to Sweden & @cemusuppsala.bsky.social at Uppsala Uny. Sadly the Hamburg-Stockholm night train only links with UK’s London-Centric network, hence the added expense of a Hamburg hotel if you live North of the M25. Still, compared with many parts of the world Europe has a great train network.

Short presentation (< 15mins) on just how vanishingly small are our remaining carbon budgets for 1.5 & 2°C - both globally & when downscaled to wealthy industrialised nations. In a handful of years our Paris 2°C commitment will go the way same way as has 1.5°C.

I’d like to think this reflects a deep engagement & concern around climate change, but it’s a cold & snowy evening in Hebden Bridge so perhaps people are just saving on heating … but this was a surprise!

I got the impression a few posts ago you didn’t like “small group” framing. Now it seems ok - with the “relatively” term I’d included?

Can you provide data/sources to demonstrate what you’re saying about it not being “a relatively small group”? As I understand it there is a wealth of data to show the opposite of your opening point.

Disagree: & please note I referred to “a relatively small group” & did not limit it to the Global North. The often rising Gini index (for all of its shortcomings), gives a sense of the depth of this inequality in many nations. Also the attached plot captures the huge & ongoing asymmetry.
