The Australian newspaper has been claiming a "forensic audit report" shows BoM's temperature data has "widespread error". For 15 years climate sceptics have been claiming a conspiracy around the data. Is anything different this time?

Latest Temperature Check column on the reaction to the landmark climate decision in the high court. Not so much “net zero on steroids” as an attempt to cut the steroids driving the planet’s climate to ever deadlier extremes.

🌊 Antarctic winter sea ice at 3rd-lowest level on record. “How sensitive is the global climate system to this loss of sea ice? We're still working to put numbers on that. But the system is changing faster than we are understanding it.” — Will Hobbs @utas.edu.au ▶️ www.theguardian.com/world/2026/s...

A month of broken records for temperatures around Australia. Hottest September ever for minimums across the continent, scores of places setting records for warmest September. A snow depth gauge in the NSW alps fell to zero - a first for any September since it was deployed in 1954.

A story of our time: Approval of biggest coal project in NSW planning commission’s history described as ‘infamous betrayal’. Independent Planning Commission says climate change impacts from Hunter Valley project will be ‘outweighed’ by economic benefits.

Busy few days… more news from me. “ It will go down in history as an infamous betrayal of the public trust.”

News from me: Antarctica’s winter sea ice has peaked at its third-lowest level on record, falling a million square kilometres – or almost 400,000 square miles – short of the long-term average, scientists have confirmed. "This is not a future problem. It’s a now problem.”

What’s more informative? That a fossil fuel project will emit 809 million tonnes of CO2? Or that it will cause almost half a million people to be exposed to unprecedented heat? A new tool tells that story, and fossil fuel corporations are unlikely to like it. www.theguardian.com/environment/...

Corporations claim their fossil fuel emissions are a drop in the ocean. But what if we could count the real cost? - Carbon Impacts Tracer tool can estimate climate impact from emissions across 8 metrics, including lost food Story by @readfearn.bsky.social www.theguardian.com/environment/...

The 0.04 kg m² increase in water vapour is the equivelent of 20 trillion litres of additional water, or 20 cubes of water, each a kilometre wide, high and deep. We are playing with very dangerous forces. www.theguardian.com/environment/...

Nice article by @readfearn.bsky.social about the Aug. 2026 record in atmospheric water vapor. My only criticism: they misspelled vapor throughout the article. Come on, guys, use a spellchecker next time. www.theguardian.com/environment/...

From me. Almost 400 native Australian bird and mammal species have been assessed as being at a high risk – or worse – from the deadly H5N1 bird flu virus, a federal government assessment has revealed.

Fresh from interviewing far-right British anti-Islam activist Tommy Robinson, Karl Stefanovic welcomed Coalition leaders Angus Taylor and Matt Canavan for a "debate" about net zero. I watched it. Beware claims of renewables covering "two Tasmanias" of land.

We have seen a rapid escalation of H5N1 bird flue cases in Australia in recent days, and now we have (probably) the first of what will likely be many, many mass mortality events in wildlife. Story from me.

Some crazy record July temperatures in Australia's alpine region this weekend (where it is winter, for northern hemisphere followers). Mount Hotham's usual daily max temp is zero C, but it saw 12C at the weekend - 3.3C above it's previous hottest July day. More in this story from me.

Most of the corals on Australia's remote Norfolk Island are likely new species. But scientists are worried they are currently facing a triple threat of El Niño, disease and now a government-backed dredging project right next door. This exclusive from me.

How deadly bird flu travelled the world before landing on a remote Australian beach. The H5N1 virus has now reached every continent. What does it mean for some of the world’s unique species? by @readfearn.bsky.social www.theguardian.com/world/2026/j... via @australia.theguardian.com

Shark-bite trends around the world are mostly flat. But in Australia they are rising sharply. After another tragedy, people want to know what’s going on. I had a look. The answers are not simple

This is the image I sent to a few scientists this week, with some questions. The area between the orange line and the coast should be covered in sea ice. It is about the size of France. Here’s the story that come from the image. www.theguardian.com/world/2026/j...

“Antarctica’s west coast is missing an area of winter sea ice the size of France, sparking concerns for threatened penguins other marine life and global sea levels.”… an exclusive from me.

Went out to an undisclosed location - a creek in Queensland's vast Sunshine Coast hinterland - to get a closer look at Australia's incredible, and threatened, spiny crayfish. There are 52 known spiny crayfish species and 36 of them are on the national threatened species list.

Lord Howe island is a seven-million-year-old volcanic treasure trove of unique wildlife 600 kilometres off Australia's coast. After a successful program to eradicate invasive rats and mice, the island's "wonderful" and unique insect life is now bouncing back.

The Australian magpie is the most often seen bird in the country. But there are some very cool things to know about this common passerine. Here are five, including how they can recognize your face, and your voice!

I fact checked One Nation’s climate claims. It was like going back 15 years.

There’s been a lot of attacks on renewables, batteries and EVs since Trump’s war started. @readfearn.bsky.social picks apart the many issues with an attack broadcast by Channel 7, by a reporter who used to work for Shell. www.theguardian.com/environment/...

If you’ve seen or heard about Seven’s primetime “special investigation” into renewables, then maybe read this too. By me.

One from me. A conservation group known for its anti-renewables stance used AI to help them with more than 100 submissions. They pointed to papers, organizations and a wind farm that didn’t exist. They also admitted they used AI to help them answer my questions. www.theguardian.com/australia-ne...
