A surfboard that was lost near Tasmania and was found, 17 months later, in New Zealand. What did its voyage look like? We can't ever know for sure, but it's fun to dream. 🌊🏄 www.abc.net.au/news/2025-10...

Ooops 😳 Glad everyone is ok!

New research showing climate impacts from individual fossil fuel projects. 🥵 🔥 🌏 Woodside’s Scarborough project will increase global temps by 0.00039 C and result in millions of extra coral bleaching and hundreds of extra deaths from extreme heat.

Looks like we can call it. Antarctic winter sea ice max has happened and was low, but not as low as 2023 or 2024.

Spring is arriving here in Tasmania, which means it's time to think about planting tomatoes - we can learn a surprising amount about climate change just by looking at the seasons. 🌱🍅

"My biggest concern is that we are starting to see changes cascading through different parts of the Antarctic environment" - Dr. @edoddridge.bsky.social #ClimateEmergency youtu.be/Lwn329y7-AI

Are you in Hobart and looking for the perfect gift for Father’s Day on Sunday? I can’t help you with that, sorry. But, I am giving a talk to the Royal Society of Tasmania about climate change and Antarctica. All welcome! Sunday 7 September, 4pm, Geology Lecture Theatre, UTAS.

"evidence is emerging for rapid, interacting and sometimes self-perpetuating changes in the Antarctic environment" New review out today led by @climatenerilie.bsky.social brings together the rapid changes unfolding in the Antarctic. It's powerful, and sobering, reading.

“A 1.5-foot-tall wave might not seem like much, but #tsunamis are waves that extend from the seafloor to the ocean’s surface,” said Ben Hamlington, an oceanographer at NASA’s Jet Propulsion Laboratory in Southern California." #NASA #JPL www.jpl.nasa.gov/news/us-fren...

A study explores the consequences of years with low sea ice in Antarctica, including declining krill populations, warming seas, increased ice-shelf calving, and reduced access for researchers. In PNAS Nexus: academic.oup.com/pnasnexus/ar...

😳 So much for the hope that 2025 might be a little less extreme. 🌊🧊

The impacts of extreme lows in Antarctic summer sea ice are confronting. Read all about it in our new paper just out in @pnasnexus.org

The speed of change that led to previous mass excitations is terrifyingly slow compared to modern change 😳 "In the case of the Permian–Triassic mass extinction, plants were unable to respond on as rapid a time scale as 1,000 to 10,000 years. This resulted in a large extinction event."

Q: What happens when we lose Antarctic sea ice in the summer? A: Bad things. A short 🧵 New research out today: academic.oup.com/pnasnexus/ar...

What's Antarctic sea ice ever done for us? Quite a lot! It cools the ocean, protects ice shelves, supports an irreplaceable ecosystem. Oh, and helps the ocean absorb $180 billion of carbon per year. Hopefully we can figure this out whilst there still is some summer sea ice... doi.org/10.1093/pnas...

"The claim an Iranian nuclear bomb would pose an existential threat to Israel or the United States and justifies unilateral, preventive military attacks makes no sense."

Love the caption clarification in this week’s Nature Anthropocene briefing. I definitely thought it was a picture of @whysharksmatter.bsky.social 🤪

Looks like we’re heading for another very low sea ice winter around Antarctica 🌊 🧊 😔

A little-known ocean current surrounds Antarctica & shields it from warm water further north. Once a steadfast guardian of the icy continent, the Antarctic Slope Current is being transformed by the ice it protects. And it's putting the continent’s last line of defence at risk tinyurl.com/y36mwfje

Have you heard about @utas.edu.au's new climate course? I had a great chat with Mel Bush on Australian Broadcasting Corporation (ABC) Radio Hobart on Saturday about the course. You can check it out here (interview starts at 2:44:24)

There’s a current that flows along the edge of Antarctica. It helps keep the warm water away from the ice, slowing down sea level. What will happen to it as the world warms? 🌡️ 🌊 🧊 1/

Welcome home!

If you live on this planet, then this course is for you! I learnt so much while helping create the course 🤯

Found some stunning autumn fungi over Easter.

“But the consequences of losing so much sea ice are hardly limited to the poles. One of the clearest global ramifications is a reduction in the amount of solar radiation reflected from Earth back into space.”

ME/CFS research receives far less funding than other chronic illnesses. Tag your election candidates and ask them about their commitments to help people with #MECFS and #longCOVID. Remind them you're asking for a #FairGoForME and this will decide your vote! #AusVotes2025

"One by one, [the paramedics and civil defense workers] were hit...Their bodies were gathered and buried in this mass grave. We’re digging them out in their uniforms, with their gloves on. They were here to save lives. Instead, they ended up in a mass grave" www.theguardian.com/world/2025/m...

"Fundamentally, climate change, whatever else it is, is a political problem" @utas.edu.au have just released a new online course built around climate change, but it's not just an introduction to climate change.

Is giving away free chickens a good way to combat climate change and save people money on eggs? tl;dr probably not, but chickens are wonderful 🥰 and probably worth having in the garden anyway if you've got space and time.

A house that cannot be insured cannot be mortgaged. No bank will issue loans for uninsurable property. Whole areas are already becoming not just unaffordable but completely uninsurable. The implications seem too much for the duopoly to even consider.

Is your house becoming uninsurable? As Jim Chalmers prepared to deliver his budget, a very alarming LinkedIn post starting doing the rounds... Great, if grim, piece by @nickfeik.bsky.social

Fascinating story about the lack of sea ice around Antarctica leading to unusual swells on the east coast of Australia. 🌊 🏄

Some sobering statistics in @theconversation.com this morning: "This gap equates to more than a third of a full-time job. If we add up all work (domestic, care and paid), mothers have the longest working week by about 10 hours. This has changed very little over time."

Another State of the Climate report. Another year of record heat, melting ice, and rising sea levels. 😒 🌡️ 📈

Time to update the ol’ cv 😁 🥇

"I guess it's a matter of individuals' and governments' appetite for risk. Do you want to spend the money to build the infrastructure that is more resilient to a tropical cyclone, even if you might not get an intense cyclone?” Great quote from @drkimclimate.bsky.social

Lots of red there 😔 With low Antarctic coverage and a record low winter in the arctic, global sea ice reached a new low in feb. 🧊 🌊

Nominations are open for this year's Young Tall Poppy Awards. Do you know an early career researcher who is making a significant impact in science AND also goes out of their way to communicate their science to the broader community? Nominate them!

Big changes might be afoot in the Southern Ocean A 20% slowdown in the world’s strongest ocean current by 2050. 🌊

Au revoir! 👋

First batch of tomato sauce for the season 😋 🍅 ☀️

Back in December Antarctic sea ice was almost exactly at the long-term average. Now it's low and falling rapidly. Are we on track for another record minimum? 🌊🧊

Climate change is heating up our global ocean at a truly terrifying speed 🌡️ A little 🧵 1/

"The ice shelf is undoubtedly going through its death throes. Breakup events observed on other ice shelves show the exact timing of final break up is impossible to predict." ☠️🧊🌊 😔

Last year I gave away some excess dahlia tubers in a local community group and today one of the people sent me a photo 🌺 🥰
