New paper alert ! 🙂
Happy to share our new study published in The Cryosphere !
doi.org/10.5194/tc-1...
We modelled the evolution of the Greenland Ice Sheet from the LGM (24 ka) to the present and learned a lot on its former history and dynamics !

Congratulations Dr Kaitlin Naughten on receiving the EGU Arne Richter Award for Outstanding Early Career Scientists!

Her work has transformed understanding of Antarctic ice-shelf melt and future sea-level rise.

She says, “It was a lovely surprise to hear that I'd won this prestigious award."

As #COP30 heats up, superb visual storytelling in @nytimes.com about climate change & the threat of glacial lake outburst floods in the Himalaya, featuring the work of @cscottwatson.bsky.social and quotes from @kristencook.bsky.social @sonamshp.bsky.social and me. 🧪⚒️ www.nytimes.com/interactive/...

Melting Glaciers in the Himalayas Feed Lakes That Threaten Towns Below (Gift Article)

Melting ice from the Himalayas is creating thousands of unstable lakes, a growing menace to towns and cities below.

The southernmost glacier in Norway is about to extinct soon! 😰

Breifonn was not exactly a small glacier at the end of the LIA (6 km²).
But only scattered patches totalising 0.15 km² remain today, meaning disappearance in the next few years... 😱

📢 PhD opportunity at Newcastle University!

👉"Reconstructing past ice-sheet retreat and ice-ocean interactions from marine sediment cores".

This project will use new marine sediment cores to constrain the timing and drivers of past ice-sheet retreat.

That was a fab symposium on ice streams, thank you and very well done to the hosts. We also had dinner in a castle and got see Hadrian’s wall and drumlins and sheep and joke about Barnard Castle, oh and some very nice pubs

Reflecting back on how enjoyable it was to host the @igsoc.bsky.social Symposium here at @geogdurham.bsky.social. A big thank you to everyone who attended, presented and contributed to organisation! It was lovely to see so many friendly faces and to hear about some fantastic glaciological science! ❄️

If you’re in East Anglia (UK) and a bit of a Quaternary geek, check out “The Stone Index” by Mike Burgess, where he has compiled a incredible list of glacial erratics, standing stones and other “odd boulders” (1/1).

At University of Cambridge, I was asked if I maintain a sense of optimism about climate change. My answer:

Yes, because unlike cancer, where we often don't know the cause and don't have a cure, we know exactly why global temperatures are rising and how to stop it. We just need the political will.

Back to civilisation after another great field campaign to Hofsjökull with the DRUMICE project. We managed to collect over 100km of radar lines over the 2 and a half day weather window. Will put together this quick little video. Thanks to NERC UK-Iceland collaboration grant for making this happen!

Icebergs? The size of a city? 90 miles from the UK? Must be a joke, right?

No! Our new paper in @natcomms.nature.com shows massive tabular icebergs broke off the UK in the last ice age before the UK’s ice shelves disintegrated from climate warming.

Still exploring old paperwork. Here’s a funny thing: apparently I published this paper in 1987, but forgot to add it to my CV so it was never mentioned in any job applications, promotions etc… a forgotten paper! Well, belatedly I’ve put it in the pile now! I wonder what else I did and then forgot.

Paper from The International Jornal of Remote Sensing that I missed of my CV for the last 38 years!
