Accelerating ice flow at the onset of the Northeast Greenland Ice Stream
Deep in the interior of the Greenland ice sheet, ice flow is speeding up — but not due to recent changes in climate.

The Transient Sensitivity of Sea Level Rise
As we warm our planet, oceans expand, ice on land melts, and sea levels rise. On century time scales, we find that the sea level response to warming can be characterized by a single metric: the …

Normalized US hurricane damage estimates using area of total destruction, 1900−2018
We present an approach to normalize hurricane damage, where damage is framed in terms of an equivalent area of total destruction. This has some advantages over customary normalization schemes, and we …

Can we move Earth?
As the Sun slowly becomes brighter over billions of years, Earth will eventually become too hot to remain habitable. One proposed far-future solution is to gradually move Earth to a larger orbit. …

Inferring firn density from radar observations
The density structure of firn controls how snow is transformed into glacial ice and plays a key role in interpreting satellite observations of ice-sheet elevation change. Unfortunately, direct density …

Can charged particles measure gravity?
Gravity is extraordinarily weak compared to electromagnetic forces. Could it nevertheless be measured using charged particles moving in electric and magnetic fields? In this computational physics …

Compiling multiple markdown files to epub
I’ve been experimenting with different ways of converting a whole folder of obsidian markdown files to epub using pandoc. Here are some different options that I’ve explored. The longform …

Greenland Monthly Accumulation Maps (1960–2022)
How do you merge and reconcile observations of accumulated snow with regional climate model output from a reanalysis? We propose a way… Abstract Accurate estimates of snow accumulation over the …

Reconstructing global sea level
Better estimates of historical Global Mean Sea Level (GMSL) can help us understand many components of the climate system. It is a key climate record.

What controls an ice sheet's transient sea-level sensitivity?
Modern ice-sheet models are often tuned to reproduce the present-day shape and extent of an ice sheet. But does matching today’s observations guarantee reliable predictions of tomorrow’s …

Ice model emulator
State-of-the-art ice-sheet models are computationally expensive to run. A single simulation may require hours to days of computing time, making it difficult to explore uncertainties in future climate …

Elastic rebound after a Greenland megaflood
Catalina Lake is a gigantic ice-dammed lake on the Renland Peninsula in East Greenland, blocked by Edward Bailey Glacier. Roughly every two decades, the glacier dam fails and billions of tonnes of …
