Congratulations!

Exploring Global Temperature Oscillations Using a Generalized Linear Box Model We derive the solution to a generalized energy balance box model, and show how it can produce oscillations in global temperature responses Oscillatory responses can describe some general circulat...

We have a new paper out today: dx.doi.org/10.1029/2024...

This explores how the simplest climate models can be extended to include oscillatory global temperature responses, related to ocean circulation and sea ice changes.

EPOC researchers Till Baumann, Laura de Steur, Rebecca McPherson and Hege-Beate Fredriksen @hegebf.bsky.social presented their latest Arctic EPOC research at the Arctic-Subarctic Ocean Fluxes (ASOF) workshop at @icmcsic.bsky.social in Barcelona this week. Thank you for a great meeting!

I wish we had a better name than efficacy, which could better reflect its meaning and therefore avoid confusion.

My understanding is that the word efficacy is used to correct a global mean quantity when a spatial variation of the quantity causes the global mean strength to change, e.g. a typical spatial pattern of a forcing or atmospheric feedbacks in a box model with only one box in contact with the surface.

New Podcast: Is the AMOC Going to Collapse? In the latest episode of the Bjerknes Podcast, experts debate the future of the Atlantic Meridional Overturning Circulation (AMOC), a crucial component of the global climate system. Listen to colleagu...

Dive into the depths of ocean science with the latest episode from the Bjerknes Centre Podcast. Join the debate on the future of the Atlantic Meridional Overturning Circulation (AMOC). Will it collapse? Weaken? Or surprise us? Two experts discuss the likelihood of various scenarios. 🌊🧪

fair-calibrate v1.4.1: calibration, constraining, and validation of the FaIR simple climate model for reliable future climate projections Abstract. Simple climate models (also known as emulators) have re-emerged as critical tools for the analysis of climate policy. Emulators are efficient and highly parameterised, where the parameters a...

The model calibration paper for fair is now published in Geoscientific Model Development! 🎉

TLDR: how do we constrain a highly parameterised model to observational and assessed constrained ranges, with uncertainty?
