How Unusual Was the Paleocene‐Eocene Thermal Maximum?

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The Paleocene‐Eocene Thermal Maximum (PETM) was an extreme fluctuation of Earth's climate and a potential analog for future unmitigated anthropogenic climate change, but whose cause is debated. We show that fluctuations in Cenozoic benthic foraminiferal δ13 ${\delta }^{13}$C and δ18 ${\delta }^{18}$O follow a Laplace distribution. We present a

Evidence for Missing Geomagnetic Reversals From Geomagnetic Reversal Frequency Model Using Adaptive Kernel Density Estimation

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The existence of missing geomagnetic reversals has been proposed, with potential for new magnetostratigraphic age controls. We estimate geomagnetic reversal frequency from 0 to 155 Ma using adaptive‐bandwidth kernel density estimation (AKDE) to evaluate data sparseness and to assess how reversal frequency changes when recently identified ...
