A numerical study on the extreme intensification of Hurricane Patricia (2015)
In October 2015 Hurricane Patricia stormed through the eastern Pacific, taking its place as the strongest hurricane in recorded history when its intensity reached a record...- publication PDF

Characterizing seawater oxygen isotopic variability in a regional ocean...
Reconstructions of the El Niño-Southern Oscillation (ENSO) are often created using the oxygen isotopic ratio in tropical coral skeletons (δ¹⁸O). However, coral δ¹⁸O can be...- publication PDF

Assessing the costs of historical inaction on climate change
We consider alternative history scenarios in which explicit climate mitigation begins before the present day, estimating the total costs to date of delayed action. Considering a...- publication PDF
