Bar graph comparing emissions from Grok's fossil-fuelled data centres to avoided emissions from Tesla's products for the years 2023 and 2024.

Comparison of emissions from manufacturing xAI's chatbot responses (5,127,553 tonnes CO2e) versus all Tesla products (1,056,000 tonnes CO2e) with respective analyses.

*New short blog* - finally (with help) got around to getting a total estimate of Grok's climate pollution 🫠

- Once all fossil gas online, = to between half and all of Tesla's ANNUAL GLOBAL avoided emissions

- Currently, 5x the emissions of Tesla's total manufacturing

$300 tests spark call for ban of controversial product sold at Bunnings, Coles, Woolworths and Mitre 10 With the government unlikely to outlaw the dangerous product, the retailers have been urged to act.

Initially, many of the owl deaths had appeared accidental, as they had been struck by cars.

But after conducting a series of $300 tests, it became clear a common product sold in supermarkets was to blame.

Can't bring themselves to use the word 'dingo', because murdering _dingoes_ via poison, as opposed to the deliberate misnomer 'wild dogs', is deemed odious by many.

Never mind that 'wild dog' is deeply offensive to First Nations peoples too!

CSIRO 350 job cuts a damning indictment on Government priorities, misses 'golden opportunity' on research The announcement this week that CSIRO are to cut 350 research jobs is another damning indictment on Australia’s ongoing failure to prioritise research and development.

I seriously cannot get over how stupid it is to be cutting back on research right now #ThePoint

The CSIRO cuts are just the tip of the iceberg for Australia's science funding Australia is known as a country of innovators, but with a combination of brain drain, continuous cuts, and a loss of critical science projects, is Australia losing its edge?

This is why for a long time I've found the Prime Minister's Prizes for Science a rather insulting propaganda exercise

1982-83 = 0.17

2024-25 = 0.03

Feral pigs are eating 99 out of every 100 lambs on this NSW property Neville Mattick says feral pigs are eating the lambs on his farm in the NSW Central West, with fewer than one in 100 surviving this season.

Is now a good time to talk about how many lambs are killed in different parts of Australia by foxes and feral pigs as opposed to dingoes?

Oh, and what kills foxes and feral pigs, and helps to reduce their activity? Rhymes with bingo.

I have been developing techniques for the automated assessment of fire events across Australia using NAFI (firenorth.org.au) data. These are the top 10 largest across Australia so far this year. 3 of them are > 1 million hectares (Terra-Fires, 100x mega fire). The year is not over.

🚨 Launched: State of Wildfires Report 2024-25

The Americas felt the harsh reality of what it means to live on a more fire-prone planet, with extreme #wildfire episodes made 2-3 times more likely by #climate change.

Seriously?!

It was actually your own party and Anthony Albanese that scuttled the EPBC reforms last time around, to appease your W.A. Labor colleagues and mining interests!

And now you're asking us to lobby to pass legislation we haven't even seen the details of?!

I really hope that the environmental & conservation community has learnt their lessons from the safeguard mechanism fiasco. Those that should have known better were played by Labor, & threw many of their own under the bus. Now we're seeing the consequences. Let's not do the same with EPBC reforms!

Absolute must idea.

Having charged Richard Boyle for 66 offenses, tied up the courts for 6 years, spent $339,703 on external legal fees, chilled whistleblowing - with the Court refusing to convict - it’s mind-blowing the CDPP still thinks his prosecution was in the public interest. 🤷‍♂️🤦‍♂️ #auspol

However resilient country can be built, fuels at scale can be managed. Fund the tools to monitor fuels, fund the rangers on country. Watch these fires, especially their behavior related to previous burning, on the NAFI Moblie app.

It's bizarre. I can think of at least 3 scientific publications that predict (i.e., model) the uncontrolled explosion of deer across Tas. None of them were referred to in the report. weirdddd

congrats Eamonn!!

Guess where former defence ministers are? 👀

The revolving door is a real obstacle to good governance and it should be SHUT.

Gov reaffirming salmon farming expansion in Mac Harbour shows appalling disregard for the natural environment. Obsessed with appeasing big business, they’d rather offer hollow apologies later for driving the Maugean skate to extinction than take real action now. #auspol #politas

For these reasons, we cannot simply look to trends in mean precipitation, or mean evaporation, to tell us anything about changes in *extreme* precipitation or evaporative demand (i.e., atmospheric "thirst"). To do so would be deeply misleading. Yet it remains common practice.

The discourse surrounding precipitation changes in a warming climate (both public discussion and even scientific one at times) is complicated by widespread conflation of changes in averages vs extremes (and also actual vs *potential* evaporation/evaporative demand). [Thread]
