When summer temperatures above the ice sheet surpass 0°C, melting occurs at the surface. Some of this water trickles down into the pore space and...

The last glacial period was punctuated by cold intervals in the North Atlantic region that culminated in extensive iceberg discharge events. These col...

The Continuous Flow Analysis (CFA) system at Oregon State University has been developed for high-resolution measurement of various polar ice core prop...

Discontinuous ice cores retrieved from the Blue Ice Areas of Allan Hills, Antarctica, have been dated to be over 3 million years old near the bed. Thi...

The evolution of Earth's climate over the last 3 million years is characterized by an increase in the amplitude and length of glacial cycles and a gra...

Constraining the causes of past atmospheric methane variability is important for understanding links between methane and climate. Abrupt methane chang...

The deglacial period, marking the transition from the Last Glacial Maximum (LGM) to the Holocene, is critical for understanding climate dynamics and m...

Holocene temperature evolution remains poorly understood. Proxies in the early and mid-Holocene suggest a Holocene Thermal Maximum (HTM) where tempera...
