Branched glycerol dialkyl glycerol tetraethers (brGDGTs) are bacterial membrane lipids thought to be predominantly produced on land. They are used as a terrestrial paleothermometer based on an empirical relation between their molecular composition and air temperature in surface soils worldwide. The...
