2️⃣ A new study led by @icecoldwill.bsky.social in @jgroceans.bsky.social looks at the ocean's role in limiting winter sea-ice growth. A metric called “Stability at Freezing Temperature” estimates how much heat the ocean must lose to the atmosphere for ice to form.

Sometimes I feel a little boring because I don’t travel so much these days. But there are some pretty spectacular adventures just 1.5 hours from #hobart … Images from a climb on the Candlestick, Tasman Peninsula. #climbing #tasmania

I’m currently getting “friendly reminders” to complete my assessments of FT applicants. I was thinking of submitting them them 2 months late and just doing 67% of the assessment. Because who am I to argue with the ARC standard…?
Here’s @jsresearchpro.bsky.social reporting on ridiculous new ARC grant time-scales (e.g. 16 months for DPs).

The ARC “did not respond to questions about the reasons for the length of the delays or on how the changes will affect researchers’ planning”.

I reckon they haven’t thought that far ahead.

The global temperature was above average every single day of 2025.
So what is average now?
2025 goes down as the ~3rd-warmest year on record (based on ERA5).

Like in 2024, every single day this past year was warmer than the average of even the most recent reference period (1991-2020).

This is ghastly! It will have an impact not just on USA but the many nations that benefit on NCAR’s climate modelling expertise

Wait, this isn’t all dicking around and I’m supposed to be taking this seriously?
i have said this before but if you are actually interested in influencing people beyond a narrow circle of too-online journalists you will be making direct to camera videos on tiktok, instagram and youtube. if you primarily post on text-based social media then you're just dicking around.

This year's #Arctic sea ice freeze-up is clearly the latest on record for the Baffin Bay region (located between Greenland and the Canadian Arctic Archipelago). The extent of ice cover is a record low for the date there.

We have ****ed the climate. Dressing this up as temporary overshoot is indefensible. But this does not mean we are doomed, & it certainly doesn't mean there is no point in trying to turn off the fossil fuel spigot. It's time to get real with climate risks.

Unsurprising but still dismal news; at over 45 years the satellite record of sea ice is one of our longest continuous climate records. Our experts at @antarctic.bsky.social are working to ensure consistency between the NSIDC record and alternative data sources
UGH! When will it end. 😭

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.

The Earth’s climate is changing and to limit warming to 1.5 or 2°C we need to do more than reducing our emissions - but what else can we do?
