Today’s Highlights
Today’s harvest brings together two geographically and temporally distinct perspectives on water and ice in the Earth system. A landmark Science study reveals that Barnes Ice Cap on Baffin Island — the last surviving remnant of the Laurentide Ice Sheet — began reexpanding just 2,000 years ago, effectively triggering the next glaciation, only for anthropogenic greenhouse warming to terminate it by 1960 CE; this provides direct field evidence that human forcing has overridden natural glacial cycles. Complementing this paleoclimate perspective, a GRL study identifies rapid infiltration signatures in 26.6% of over 4,900 global infiltration curves using a dual-mechanism framework, highlighting that rapid and non-rapid infiltration frequently coexist in the same locale and that rapid infiltration decreases with latitude — findings with direct implications for improving infiltration representation in hydrological and Earth system models.

Late Holocene reexpansion of the Laurentide Ice Sheet
Authors: Nicolás E. Young, Gifford H. Miller, Martha Raynolds, Helga Bueltmann, Scott J. Lehman, Jonathan H. Raberg et al.

Matched topics: Holocene, Pleistocene
During interglaciations, the Laurentide Ice Sheet (LIS), which is the largest of the Pleistocene ice sheets, retreats to Arctic Canada, where it achieves a minimum configuration. The reexpansion of the LIS following this minimum marks the start of the next glaciation. Here, we show that the last remaining remnant of the most recent LIS, Barnes Ice Cap (Baffin Island, Canada), achieved its minimum interglacial dimensions after ~3.6 thousand years ago, before reexpanding ~2000 years ago, marking the onset of the next glaciation. The new LIS reached maximum dimensions in ~1960 CE, after which anthropogenic summer warming resulted in a negative mass balance, ice margin recession, and the termination of the next glaciation. The demise of the next glaciation, despite the ongoing decline in summer insolation, illustrates the influence of anomalous greenhouse gas forcing on climate.
Rapid Infiltration Signatures From Global Infiltration Observations

Matched topics: surface water, earth system model
Rapid infiltration influences rainfall partitioning, subsurface water movement, and freshwater availability, yet its large-scale spatial organization remains poorly constrained by limited observations and the lack of scalable approaches for synthesizing infiltration measurements. Here, we identify rapid infiltration signatures from a global database using a dual-mechanism modeling framework. Rapid infiltration signatures occurred in 26.6% of 4,992 valid curves. Occurrence varied among measurement methods, while rapid and non-rapid signatures frequently coexisted within closely matched local contexts. At identical recorded locations, 74.7% of qualifying groups contained both rapid and non-rapid signatures; for rapid-classified curves, the fitted rapid component accounted for a median 41.2% of cumulative infiltration. Across 83 sites, rapid-signature odds decreased by approximately 26% per 10° increase in absolute latitude. These findings provide a large-scale observational basis for investigating rapid infiltration and highlight the importance of measurement context and independent physical evidence for improving its representation in hydrological and Earth system models.
