At #BACO2025. Lots of good, exciting research. Super happy a former student from the #ESADragon 2023 training programme in Xining came to say hi

Whiteboard with equations (the navier stokes equation) on it written in green marker pen

Today my PhD student Caitlin and I were going through models (agent based and continuum) of the physics of swimming microalgae 🦠. Caitlin's investigating the movement of motile microalgae in snow ❄️ in collaboration with Mel Sandells, Matt Davey and Xanthella. #microswimmers #cryosphere #OnePlanetDTP

This painting, Pine Trees in the Snow with Rabbit Tracks by George Hawley Hallowell (c. 1925), depicts a serene winter scene. Snow-covered pine trees dominate the composition, their drooping branches forming soft, flowing shapes. In the foreground, delicate rabbit tracks cross a blanket of pristine, untouched snow. The muted blues and whites evoke the quiet stillness of a frosty winter's day, with subtle hints of green and yellow adding depth and vibrancy to the scene.

🐇 Today’s #haiku:

Tiny marks unfold,
veiled trails through white stillness curve -
paths where none have been

Inspired by rabbit footprints left in the morning's snow - each step a story, each pause a mystery.

Small differences that make a really big difference. We have a new paper just out this week on Greenland ice sheet projections of melt and runoff. "With identical forcing, Greenland Ice Sheet surface mass balance from 3 regional climate models shows a two-fold difference by 2100" In this post I go into some of the detail on why we think that is and what we can do about it...

It's only right that my first post here is sharing Scotland's map of named ice gritters. You can follow where they all are in real-time.

Have you seen the hydrology climate stripes?

If not you might have missed the yearly WMO report on the state of water resources. Take a look: wmo.int/publication-...

For those who already know the report, there now also is a higher resolution version available!

A quick reminder on how to contribute to uksnowmap.com ahead of any possible #uksnow tomorrow 👀

Post with the hashtag #uksnow, the first-half of your postcode, and a snow rating x/10 and help draw a real-time map of where it is snowing in the UK.

Ah Reading, it’s been a while. Of course, no university travel experience is complete without spending 2 hours negotiating with the travel management company to get into the hotel they’ve booked and supposedly paid for but you still have to fork out twice the price for. #UnexpectedlyWayOutOfPolicy

Microplastics promote cloud formation, with likely effects on weather and climate Clouds affect Earth’s weather and climate in many ways. New research suggests that the presence of microplastic particles could alter these processes.

The real chemtrail that we’re not talking about.

A map of flight paths emanating from breeding colony of gulls, with this caption: Early on, LifeWatch noticed something odd. Most gulls were making daily trips to Mouscron, a city on the French border 65 km away. They went to investigate and found the birds bingeing on discarded snacks at the Roger & Roger potato factory.

Today in relatable science: Gulls making a mysterious daily trip that turned out to be to a potato chip factory

Picture of me and David Ashmore installing a weather station and time lapse camera next to a marine terminating glacier in Greenland

Hello new, wonderful Blueskyers! In case you're wondering who I am, I spend most of my time thinking about glaciers and ice sheets past, present and future, currently mainly through satellite and field based remote sensing. Also very interested in how to get the science that we do communicated to...

This winter's snow forecast is bleak, but even worse, the last thirty years has seen a major loss of snow throughout the United States compared to the twentieth century. Global warming is wiping out glaciers, ice caps, and snow.
