Branched glycerol dialkyl glycerol tetraethers (brGDGTs) are a group of temperature-sensitive membrane lipids found in bacteria that have been widely used in palaeo-temperature reconstruction. Despite recent advances in analytical methods, calibration datasets and statistical modelling approaches, one of the current challenges in Quaternary science remains in determining the most appropriate calibration model for reconstructing past changes in climate. We address this challenge by expanding e...
