Finally the graph that shows the fallacy of the ‘it’s all happened before’ argument. #ithasnt

Just remembered this jaw-dropping graph by @oceansclimatecu.bsky.social showing the rate of change in CO2 during the previous two deglaciations of the Pleistocene (which, as a fun aside, featured ~400 feet of sea level rise) as compared with today

🔴 Santos Limited has racked up a 10th straight year of zero corporate tax payments from $48 billion in sales.

🔴 Ichthys LNG Pty Ltd paid zero corporate tax for the 6th year running, from $43 billion in sales.

I’ll be presenting on the NCRA with my friend Prof. Lucas Walsh and economist Richard Dennis @richarddenniss.bsky.social at the Royal Society of Victoria this Tuesday 6pm - come on down

September 2025 was the third warmest September on record at 1.47C above preindustrial levels in ERA5, behind only the prior two years (2023 and 2024).

With 9 months of the year now in, I estimate 2025 will approximately tie with 2023 for the second warmest year on record at ~1.48C.

“On September 17, Antarctic sea ice likely reached its annual maximum extent of 17.81 million square kilometers (6.88 million square miles). The 2025 maximum is the third lowest in the 47-year satellite record above 2023 and 2024.”

❄️ Fact vs Fiction

Q: Has Antarctica’s ice mass rebounded after increasing in recent years?

A: Whilst fluctuations have occurred, the continent has lost around 2.5T tonnes of ice since 2002.

Our Director @deformedearth.bsky.social (UTAS) explains in AAP FactCheck.

Scientists call foul on Antarctic ice rebound claim
Experts have said the long-term decline in ice mass is clear and that cherry-picking small periods of time gives a misleading picture.

Noting guru Eun-Pa Lim explains on X that its still very early days for the Sudden Stratospheric Warming, and what we have seen so far is a 'minor warming'
windjunky.bsky.social
Great explainer by Martin Jucker @drjucker.bsky.social on the emerging Sudden Stratospheric Warming event over Antarctica, noting it is just one climate driver at play and does *not* lock in another 2019-like spring/summer.
(Thanks also to Martin for citing our 2019 SSW article with Harry and EunPa)

The stratospheric polar vortex high above Antarctica has rapidly heated up. These sudden bursts of heat can bring rapid weather changes in Australia.

“Mosquito borne diseases are the most climate sensitive
transmission type of communicable disease in Australia, with other vector borne diseases, food and water borne diseases, zoonotic diseases and environmental diseases also aggravated by multiple climate conditions”

Burro indeed!! Top work DW

The work of EunPa Lim (and Harry Hendon) is quite convincing. There have been some great advances in our thinking around the influence of the southern SSW over the past several years.

I’d ask what the insurance is/will be… #sealevelrise #NCRA
windjunky.bsky.social
I think you are missing the point. CCIA was solely about climate and used AR4 era models (roughly 2010) [NCRA is using AR6 models (roughly 2020) ], whereas NCRA explicitly includes Exposure and Vulnerability data to determine who and what is at risk. That has never been done on this scale for Aus.

The joke is on anyone who believes we are tracking a SSP1-2.6 future, as the American think tanker suggests we are should have used. That said, clowns like jokes 🤡
(Like SSP5-8.5. it is considered implausible.)

Mmmmm…
Who to believe on climate change impacts on Australia over the coming century?
Australian peer review published climate scientists from BoM and CSIRO inc. several IPCC and WMO experts, or,
The Daily Mail.
I had to reassure myself it wasn’t 1 April. #dinosaurs
