It’s great to be in Fukuoka for #AOGS2026. For this Sydneysider, experiencing WBGT over 34C also really puts heat-stress projections into perspective.

Still amused at atmospheric science journal proofs coming back with "reanalyses" - as in the plural of reanalysis - changed to "reanalyzes".

Just spent a wonderful week visiting Uluṟu and Kata Tjuṯa on Anangu land. Peaceful and magical places.

Wow, @egu.eu really badly wants candidates for treasurer and ECR union rep. To their credit I normally skim-read these emails but after the 30th identical email I did read it properly.

How much is climate change already costing us? New work by Timothy Neal and Ben Newell shows that in New South Wales, Australia, that number is on average about $20k in lost income per person per year. Climate change is already a quality-of-life issue. theconversation.com/climate-chan...

Climate change has already made Australians in one state much poorer, and more’s to come

It’s time to recognise climate change for what it is. A new study shows it’s a current and ongoing threat to our standard of living.

Interesting example of a compounding event - March 2025 in Türkiye was so warm that fruit trees flowered early. Then hailstorms and cold temperatures came in April. Fruit crops were ruined and prices doubled for months. From this paper by @regclimo.bsky.social et al: www.nature.com/articles/s43...

This is an excellent recap of compound weather and climate events in 2025. It is also a great explainer of the different types of compounding that can occur, with strong examples. www.nature.com/articles/s43...

Which compound weather and climate events mattered most in 2025? In a new report in @natrevearthenviron.nature.com we've taken a systematic global view to survey these events and their impacts across 5 typologies. rdcu.be/fmeAh We hope it proves useful for looking back on 'the year that was'...

New research led by Tim Raupach and Steven Sherwood and published in Nature Climate Change suggests the atmospheric conditions that favour hail formation are shifting towards cooler regions and cooler times of the year. For more: 21centuryweather.org.au/hail-conditi...

Where will hail risk increase in a warmer world? A new Nature Climate Change study by CCRC & ICRR researchers finds hail-prone conditions are shifting poleward, with winter hail risk projected to increase in some agricultural regions.

In our new paper in Nature Climate Change, we show that hail conditions are projected to shift poleward with climate change, and that summer decreases and winter increases in hail hazard mean that winter crops may face rising risks from hail. www.nature.com/articles/s41...

Important new hail work by Zhang et al., in @nature.com today. Under warming scenarios globally, large hailstones become more frequent and smaller hailstones decline (with regional variation). Another reminder that reducing greenhouse gas emissions is imperative for a safer future. rdcu.be/fk8Fd

Our poster session for #EGU26 ITS4.4 is very active with lots of great discussion - interdisciplinary science from flooding rain, hail, to heat stress and financial risk.

Finishing up the talks for ITS4.4 at #EGU26, Jung-Ching Kan talks about heat impact forecasts for Sweden using machine learning.

Nicolò Ardenghi now tells us about decision-making for managing important climate risks in Venice, in ITS4.4 at #EGU26.

Staying in finance at ITS4.4, Marco Maneta now joins us online to talk about climate risk financial modeling. #EGU26

Moving to the financial sector in ITS4.4 at #EGU26, we now have Chiara Cagnazzo talking about the @ecmwf.int C3S climate services for assessing physical climate risk.

Till Sterzel now presents work on urban-planning adaptation under climate change, in ITS4.4 at #EGU26.

Now in ITS4.4 at #EGU26, Sebastian Vicuña tells us about climate change risks in semi-arid coastal basins with a focus on Chile.

Next in ITS4.4 at #EGU26, @lucialayr.bsky.social presents her work on taking future climate projections into account in post-fire management.

Our session ITS4.4 on interdisciplinary approaches to complex climate risks is getting underway at #EGU26. First up Nicole van Maanen talks about challenges (and solutions) for comprehensive risk management. Excellent turnout for a morning session too!

On Tuesday afternoon in AS1.7 at #EGU26 I'm presenting my work with Sarah Bang and John Allen on simulations of satellite-detected hail events in the Australian tropics. meetingorganizer.copernicus.org/EGU26/EGU26-...

Tuesday at #EGU26, Ben Newell, @janalbrecht.bsky.social, @vitusbenson.bsky.social and I co-convene ITS4.4 "Interdisciplinary approaches to addressing complex climate risks". Our exciting lineup has research on extremes and decision-making from fire to hail. Talks 8.30 in -2.62, posters 10.45 in X5.

I’m excited to be on the way to #EGU26! So much amazing science to discuss. I’m talking on Tuesday about hailstorms in the tropics - here’s some convective activity in that neighborhood I saw on the way.

It's funny how often AI summaries of online meetings start with "the meeting began with a discussion of connection difficulties that were then resolved"

I had a great time talking with @sarahinscience.bsky.social and @instrachan.bsky.social about Twister on the @21stcenturyweather.bsky.social podcast Totally Cooked. How I wish we could fully analyse rolling data in real time like the scientists in the film! open.spotify.com/episode/3u8N...

New paper! It's hard to test convective schemes in weather models because we lack reliable ground truth on how they "should" act. Here, we attempted to quantify how schemes should respond to small changes in temperature and humidity. agupubs.onlinelibrary.wiley.com/doi/10.1029/...

We have an open postdoc position at @ccrc.bsky.social. This postdoc will work with @jasonpevans.bsky.social, Fiona Johnson, and me, together with partner organisations NSW DCEEW and @nswses.bsky.social, on rainfall extremes and flooding. external-careers.jobs.unsw.edu.au/cw/en/job/53...

I had a great time representing UNSW Science at Science Meets Parliament #SMP2026 in Canberra, from friendly meetings with parliamentarians to learning about all the ways everyone can have their say in our democracy. A great opportunity to learn and share.

The "largest ever" oil disruption should be another strong reminder that renewables are not only the right choice for reducing emissions but also crucial for energy independence. www.nytimes.com/2026/03/12/w...
