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...

Sadly, Famous Dinosaur Tracks Were Not Made By Sauropods Walking On Their Hands
On seeing a line of footprints made by giant sauropods' front feet only, leading scientists jumped to conclusions, but closer observation doesn’t back them up.

Firings are happening right now at the National Science Foundation. Essential staff are being cut.
This isn’t about the budget. If it was, they’d be going after the military (17%) or state appropriations (38%). NSF is 0.7% of the federal budget. All federal employees make up only 4% of the budget.

Watching all-white cadres of scientists who remained silent thru the DEI-purging, but who’re suddenly freaking out because their segment of science might now *also* get threatened (“my field station!”) does little to dispel this gap. 😑

Trying hard to walk uncomfortable lines between two truths:
“What’s happening to US science is inexplicably bad”

“US science has for *so long* systemically excluded its own marginalized members, was always brittle, and now doesn’t have the legs it needs to meaningfully resist.”
