Mahé Perrette — probabilistic climate science

I am a researcher and consultant in climate science with 15 years of experience, focusing on probabilistic future projections and sea level rise. Other works cover a wider range of topics, from future climate hazards on infrastructure to paleoclimate reconstruction and remote sensing. They are usually programming-heavy (mostly in Python, lately also Julia) and sometimes feature simple web apps.

I am based in southern Italy but have built most of my career in Berlin, where I still go on a regular basis.

A non-exhaustive list of organizations I have collaborated with:

I am available for freelance work — research collaboration, climate impact consultancy, and scientific software: see Services. Don’t hesitate to reach out (contact at the bottom of the page).

Latest work

Bayesian reconstruction of the Last Glacial Maximum with Alex Robinson at AWI (ongoing)
New preprint describing our RIME-X climate impact emulator, led by Niklas Schwind [22], following RIME v1.0 published by Edward Byers from IIASA [20] (a collaboration with Climate Analytics)
We published a sea level paper in Science Advances [21]. See the companion app ! (a collaboration with PIK)
