Why have the sea surface temperature suddenly risen in 2023/24? 🌊 Is it true that climate models cannot simulate such SST jumps? What is common to such jumps? How will SSTs evolve over the next months and years? Are we in uncharted territory? More from our recent study in Nature is here👇

post52.3 ice shelves melt, from ocean below. "It’s from the ocean back to the ice, and then back into the ocean again, that can trigger a runaway change where we do see the overturning potentially collapse altogether" @profmattengland.bsky.social said. // same as #AMOC grist.org/climate/anta...

We looked at impacts of a shutdown of the AMOC on Australia in our Tipping Points workshop report for the National Climate Risk Assessment. Unlike N.Hem, it may enhance warming in the S.Hem/Australian region, and could induce a La Nina-like wetting of northern Australia www.csiro.au/-/media/Envi...

This Nature article argues that the recent declines in Antarctic sea-ice, ice-sheet, abyssal meridional overturning circulation (MOC), and marine species habitats point to a potential abrupt changes in the Antarctic environment: 🌊🧪🥼❄️ www.nature.com/articles/s41...

Part 2 of my interview with Robyn Williams on the ABC Science Show, where we discuss funding cuts to US climate science, the threats of sea-level rise, and whether we're already too late to deal with climate change. www.abc.net.au/listen/progr...

This week I joined the wonderful Robyn Williams on the ABC Science Show to discuss our recent North Atlantic Nature paper plus a range of other topics — marine heat waves, polar vortex wobbles, the AMOC, and the deep cost of climate inaction. Part 2 airs next week.   www.abc.net.au/listen/progr...

20 straight days with 30 °C in Finland! Truly unprecedented heatwave still in full swing with maximum today about 32-33 degrees. Even the Arctic regions (e.g. Sodankylä Tähtelä) have seen three weeks above 25 °C, and may rival tomorrow their August heat records.

Our piece in @theconversation.com today: As US climate data-gathering is gutted, Australian forecasting is now at real risk theconversation.com/as-us-climat... And it's not just Australia that will lose out. Forecasting all around the world will be set back decades if these cuts go through.

Tracking and predicting weather and climate is a global endeavour, threatened by Trump. theconversation.com/as-us-climat...

Our article on the impacts US cuts to NOAA/NASA/NSF could have on Australian and global weather and climate and oceans monitoring and forecasting - and the steps Australia needs to protect itself. Written with a significant group of amazing co-authors theconversation.com/as-us-climat...

Congratulations @adele-morrison.bsky.social !!! Awarded the IAPSO ECR Medal in Busan today!! Amazing accolade for an exceptional scientist and all-round great person.

For anyone interested in a deeper dive into our recent Nature paper on the 2023 N. Atlantic marine heatwave nature.com/articles/s41... plus some discussion of recent work related to the SMOC, @danmiller999.bsky.social does an outstanding job as host with cameos from @LeonSimons8.bsky.social 👇👇👇

Thursday at 3pm PT (special day/time) on Climate Chat: Cause of Extreme North Atlantic Warming in 2023 with @profmattengland.bsky.social. We'll also discuss AMOC & S. Ocean. LinkedIn link: www.linkedin.com/events/73511...

Look forward to chatting with @danmiller999.bsky.social & @leonsimons.bsky.social this Friday 8am AEST (Thursday afternoon/evening US time). Will cover a range of topics: the 2023 North Atlantic marine heatwave, Southern Ocean circulation and the AMOC

🚨 NCI-powered research reveals what drove 2023’s record North Atlantic marine heatwave 🌊☀️ Scientists used ACCESS-NRI ocean models, run on NCI’s supercomputer & data systems, to uncover the role of record-low winds & shallow ocean layers. 📘 www.nature.com/articles/s41... #HPC #NCIresources

Out today in Nature, our paper on the drivers of the record 2023 summer heating of the North Atlantic. Temperatures warmed to record levels in just a few months. The impacts on climate & ecosystems were severe. A thread on how this work came about and what we found.👇👇🧵 www.nature.com/articles/s41...

Our study just out in Nature: the extreme North Atlantic heat in summer 2023 was mainly due to weak winds causing shallow mixed layers, which heat up more quickly. Global warming is causing a trend toward shallow mixed layers, making such extremes more likely. 🌊 www.nature.com/articles/s41...

Antarctic meltwater is making the surrounding ocean less salty & less dense, speeding up the Antarctic Slope Current, which acts as a barrier against warm water. The faster current causes eddies in its wake, which can amplify the transport of warmer water towards Antarctica, increasing melting.

Valuable lessons for Australia’s path to net zero. Superb piece by @naomioreskes.bsky.social theconversation.com/fossil-fuel-...

Submitted! Our application for a new ARC Centre of Excellence focused on our changing oceans has been submitted! Thanks to my amazing team of CIs who put in a big effort over the past 12 weeks since news we’d been shortlisted, capping off a 3 yr period of planning & workshops preparing for the bid!

This Sunday at Bondi Beach Pavillion: Q&A on ocean warming and other climate change impacts on our oceans.

Suppression of climate data built up by decades of hard working scientists dedicated to measuring and understanding planetary health. Removing facilities that measure climate change will not change US exposure to its catastrophic consequences 🔥🌀🌊🌪️

Ocean warming has become so significant it’s now a semi-regular feature of TV weather reports here in Australia. A warmer ocean bleaches corals, raises sea levels, melts ice caps, stresses ecosystems, drives flooding rains and amplifies humidity. None of this is good news.

How will media report on this new AMOC study? www.realclimate.org/index.php/ar...

Without NOAA we would be badly unprepared for extreme weather and climate events, sailing blind into a dangerous storm. Funding cuts make absolutely zero economic sense. theconversation.com/noaas-vast-p...

Rainfall extremes and severe flash floods are expected to get worse under global warming. It may take a little while to do an attribution study for this event, but just a reminder of what we found for the Brisbane floods of 2010/2011. agupubs.onlinelibrary.wiley.com/doi/full/10....

Stoked to get an ARC #DP25 grant with Madi Rosevear and @profmattengland.bsky.social to include ice shelf cavities into #COSIMA model configs, and to understand processes controlling heat delivery to Antarctica’s ice shelves. We'll be looking for a postdoc, so get in touch if you're keen!

Have finally decided to ditch twitter for BlueSky. Good to be here!
