The International Court of Justice 2025 determination in “Obligations of States in respect of climate change” notes that States are obliged to mitigate greenhouse gas emissions, and to not do so is an internationally wrongful act.

Western Brisbane is a place to watch, fire wise, this fire season IMHO. Stay dafe @gergyl.bsky.social

No, negative SAM means westerlies over the land into eastern Australia, so dry and warm. Great paper by EunPa Lim et all. on 2019 SSW event.

Remember also other climate drivers in 2025 - neg IOD and possible La Nina. Its complex.

Approving new coal mines assuming they will be profitable aligns Australia to IPCC's SSP5 'fossil fueled development' tajectory.
SSP5 means *at least* 2.7C global heating, likely 4C, by 2100.
The government's own National Climate Risk Assessment shows 3C is disasterous for every Australian.

The importance of 'NOW' from IPCC...
"limiting {global} warming to around 1.5°C (2.7°F) requires global greenhouse gas emissions to peak before **2025** at the latest"

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

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.

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.
