Weather and Climate ExtremesHeat waves, defined by consecutive days of abnormally high temperatures exceeding local or regional norms, have been extensively studied during the summer season. However, their characteristics and driving forces in mid-to-late spring (April and May) and

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract The long‐standing hypothesis that an ice sheet covered the Tibetan Plateau during the Last Glacial Maximum (LGM) has been refuted. Further research has indicated that the Plateau experienced more extensive glacial expansion during Marine Isotope Stage (MIS) 6 than during the LGM.

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Drivers of multi‐centennial global monsoon variability remain debated, with internal variability poorly understood. Using nine CMIP6 pre‐industrial millennial simulations, we find that the Atlantic meridional overturning circulation (AMOC) correlates with multi‐centennial fluctuations in the Afro‐Asian summer monsoon (AfroASM), which includes ...

Observation‐Informed Machine Learning Convective Scheme: A New Training Strategy
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Machine learning (ML)‐based schemes face challenges in online stability and biases because of the accumulated errors during long‐term integrations. Here, we propose a new ML training strategy for the convection process that provides online corrections to tendencies in a more systematic way with significant improvements in stability and bias ...

Holocene Climate Changes: Unraveling Processes, Mechanisms, and Impacts Across Spatiotemporal Scales
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract As the most recent interglacial period and the timeframe for the development of human civilization, the Holocene provides a critical perspective for understanding future climate under continued global warming. This special collection focuses on Holocene climate changes and features 14 interdisciplinary studies.

Fluorination of Silver Phosphate in Nickel Reaction Vessels for Triple Oxygen Isotope Analysis
Rapid Communications in Mass Spectrometry, Volume 40, Issue 7, 15 April 2026.ABSTRACT Rationale Increasingly, more laboratories are measuring the triple oxygen isotope values of phosphate. Standardization is key to having good interlaboratory results. Here, we present the triple oxygen isotope values of a suite of standards using fluorination and compare them with previously reported triple oxygen isotope values. Methods Silver

Precessional quantities for the Earth over 10 Myr [PDF]
The insolation parameters of the Earth depend on its orbital parameters and on the precession and obliquity. Until 1988, the usually adopted solution for paleoclimate computation consisted in (Bretagnon, 1974) for the orbital elements of the Earth, which

The linkage between autumn Barents-Kara sea ice and European cold winter extremes
Frontiers in ClimateWhile the Arctic's accelerated warming and sea ice decline have been associated with Eurasian cooling, debates persist between those attributing this to sea ice retreat and those to internal variability.

Lessons from paleoclimates for recent and future climate change: opportunities and insights
Frontiers in ClimatePaleoclimate information has played an instrumental role in showing how fast climate can vary and how large these changes can be. It provided the first vivid demonstration of the relationships between atmospheric greenhouse gas concentrations and surface
