Steady decline in mean annual air temperatures in the first 30 ky after the Cretaceous-Paleogene boundary

Abstract The Cretaceous-Paleogene (K-Pg) boundary marks one of the five major mass
extinctions of the Phanerozoic. The ways in which the climate system responded to a bolide
impact and extensive volcanism at this time over different time scales are highly debated.
We used the distribution of branched tetraether lipids (brGDGT) from fossil peats at two sites
in Saskatchewan, Canada (paleolatitude~ 55° N), to generate a high-resolution (millennial)
record of mean annual air temperature (MAAT) spanning the last~ 4 ky of the Cretaceous …
