The Vietnamese Bach Ma Mountain Peak station recorded one-day rainfall of 1,739 mm - close to the global one-day record and perhaps a new record for the northern hemisphere. It is part of a deluge Viet Nam has seen in October, shattering 35 precip records. e.vnexpress.net/news/news/en...

We need to be worried about this. 1st some countries (Saudi Arabia) refused to welcome the 1.5 report, now they (and others) are flat out refusing to set a date for when the AR7 can be approved. Heads in the sand sort of decision-making on climate change is not just foolish it is evil necropolitics.

It’s one thing to have different environmental/health priorities for your foundation, it’s quite another to have been bankrolling one of the primary sources of bullshit on the topic.

Pretending that fossil fuels can be harmless is 100x worse than denying climate science. Not sure I've seen anything that lay it out with such efficient density as this @danrepacholimp.bsky.social speech.

I lay it all out at @crikey.com.au for you -->>

www.crikey.com.au/2025/11/06/n...
But one single speech from a Labor MP still somehow hit me hard, despite the knowledge that the party has notoriously bad form on climate. As I read in Tim Hollo’s newsletter, Hunter MP Dan Repacholi gave a short speech on “net zero” in parliament, claiming pretty simply that coal mines would not need to shut down if Australia reaches Labor’s target. I want to highlight a few excerpts, because they accurately geolocate the actual problem. I don’t know if it’s selective hearing, genuine misunderstanding or just plain ignorance, but, whenever we talk about reducing our emissions, those opposite leave out the most important word in ‘net zero’: ‘net’. Net zero does not mean shutting down industries. Net zero does not mean zero emissions. Net zero is about one thing: offsets. It means we take as much carbon out of the atmosphere as we put in. It is simple and practical, and industries in the Hunter are already doing it. By my calculations, the emissions released by Australia’s coal exports when burned add up to around 2.8 gigatonnes, since the moment Labor was elected. The total global carbon capture capacity is about 0.005 gigatonnes of carbon capture per year, and only a small fraction of that counts as actual removal from the atmosphere (rather than just skimming a fraction off a bunch being released). There are no operational carbon removal facilities in the Hunter region. Even if you accept the shrugging off of exported emissions as irrelevant, the idea that the Hunter coal mining region is engaging in permanent carbon sequestration for operational emissions is a flat-out fabrication.

Seems bad. Anyone yet factoring in 10m of sea level into infrastructure planning?

Up to 59% of Antarctic ice shelves may be at risk of disappearing under high-emission scenarios by 2300, according to an analysis of the effect of ocean warming in Nature. This could result in up to 10 m of global sea-level rise. go.nature.com/47Ag4k1 🌊 🧪
This is figure 1, which is a schematic of the processes that contribute to the Antarctic ice-shelf mass balance.

"Incentivising new fossil fuel production, implementing weak, offset-ridden policies, and seizing up at a critical moment of coal power elimination are all notable climate failures".

But media's obsession with LNP conflict, and failure to grasp 'net zero', lets Labor get way with climate murder.

It wasnt our enviro laws that were too weak to protect the Skate or stop the North West Shelf, it was our Ministers.

Thats why Labor is trying to get the Coalition to help them water them down…to save Enviro Ministers the embarrassment of always saying yes #climate

It wasn’t the laws that were too weak to stop those projects, it was the ministers
The Prime Minister is betting that by 2028 people will forget the North West Shelf and EPBC backflips, but it would be a brave backbencher willing to make that same bet.

People can and should have nice things.

If someone writes a report saying "we build transport that is too nice and that's why projects are expensive and that's why we don't build more of them" then not only should their analysis be discarded as junk but they should be pilloried.

It's Halloween, and to celebrate (?) I made a big scary decision...

I love climate research and polar science, but academia broke me. And more importantly, I feel like climate comms is where I can have more impact.

Impact of flights on global warming severely underestimated by many carbon calculators & offset schemes that don’t properly account for taxiing, sub-optimal routing or non-CO2 climate effects which are larger component:
