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.

Change in iceberg calving behavior preceded North Sea ice shelf disintegration during the last deglaciation - Nature Communications
Massive tabular icebergs broke off of the UK during the last ice age. The widespread break-up of the ice shelves which produced these giant icebergs can be traced to around 18,000 years ago, and likel...

Can AI help yield new insights from vast amounts of Earth data?
We use large-scale data and neural nets to find the constitutive laws of glacial ice, which differ from commonly assumed forms in conventional models. #ScienceResearch

Important paper in Nature today about collapse of the West Antarctic Ice Sheet. There is a positive isotope anomaly at Skytrain Ice Rise during the last interglacial, consistent with what we found in our high-resolution water-isotope simulations when WAIS collapses.

The Ronne Ice Shelf survived the last interglacial - Nature
Sea salt data from an ice core record show that Antarctica’s Ronne Ice Shelf survived the last interglacial, the last period of enhanced and sustained global warmth about 125,000 years ago.

Hello from the Brunt Ice Shelf! ⚡🧪
The RIFT-TIP team are using ice cores and seismology to model how huge fractures travel across ice shelves.
With just a few weeks left, they've been putting in a real shift:
🧊 4 ice cores drilled
🔍 60km of radar transects taken
⚡ 64 surface seismometers set up
