Trends and variability of heat waves in Europe and the association with large-scale circulation patterns

Weather and Climate Extremes
Heat 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

Coral δ13C Reveals Little Ice Age Dimming of Tropical Surface Shortwave Radiation Not Captured by Climate Models

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Tropical low‐cloud feedback is the largest source of uncertainty in climate sensitivity, yet multi‐century records of surface shortwave radiation are scarce. We calibrate Porites coral δ13C against satellite photosynthetically available radiation (PAR) and reconstruct monthly PAR for the northern South China Sea during the Medieval Climate ...

Three Centuries of ENSO Variability Inferred From Muna, Sulawesi, Indonesia Teak δ18O: Limited Response to Radiative Forcing

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract We present an annual resolution oxygen isotope anomaly (Δδ18 ${\Delta }{\delta }^{18}$Oc) record, derived from eight teak (Tectona grandis L.f.) tree ring‐dated δ18 ${\delta }^{18}$Oc series from Muna, Southeast Sulawesi, Indonesia (5.3° ${}^{\circ}$S, 123° ${}^{\circ}$E).

The first firn core from Peter I Island – capturing climate variability across the Bellingshausen Sea [PDF]

Climate of the Past
Peter I Island is situated in the Bellingshausen Sea, a region that has experienced considerable climate change in recent decades. Warming sea surface temperatures and reduced sea ice cover have been accompanied by warming surface air temperature ...

California Temperature Since 1520 CE Shows Interactions in Extremes of Heat, Drought, and Fire

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Summer maximum temperatures (Tmax ${T}_{\text{max}}$) in the Sierra Nevada have risen rapidly since the turn of the 20th century, especially above 1,500 m where trends in the south exceed 3°C century−1. To place this warming into context, we developed a 504‐year reconstruction of growing‐season (April–September) Tmax ${T}_{\text{max}}$ (1520 ...

Size of the cave bear population and skeletal distribution from Urşilor Cave, Romania

Travaux de l'Institut de Speologie Emile Racovitza, 2016
Spatial distribution analyses of fossil bones are often used in cave taphonomy for i) assessing directly the size of a given fossil population and ii) indirectly, for palaeo-environmental reconstructions.

Constraints on Past CO2 and Climate Sensitivity From Global Temperature and Sea Level Reconstructions Across the Plio‐Pleistocene

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract In contrast to previous approaches, new reconstructions of changes in global mean surface temperature and global mean sea level (GMSL) include large variability in GMSL throughout the Pleistocene. Here we assess these reconstructions from an energy balance perspective by using them to force a global carbon cycle model in different scenarios ...

Radar Specularity Content Indicates a Strong Geothermal Heat Flow Gradient in Antarctica's South Pole Basin

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Accurate estimates of geothermal heat flow (GHF) are critical for predicting basal melting and identifying stable sites for ancient ice, yet GHF remains one of the least constrained boundary conditions for the Antarctic Ice Sheet. We evaluate nine published Antarctic GHF models against radar‐derived specularity content in the South Pole Basin (

Effects of Warming and Stratospheric Aerosol Injection on Tropical Cyclone Distribution and Frequency: Results From a High‐Resolution Global Circulation Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract As global circulation models (GCMs) have increased in spatial resolution, more realistic tropical cyclones (TCs) and TC distributions have been simulated. Whereas prior research on TC climatologies has relied on proxies like Potential Intensity and synthetic storm models, the cyclones simulated by newer TC‐resolving GCMs can now be analyzed ...

Holocene Hydroclimatic Variations Over Western and Central Asia as Inferred From Speleothem Isotope Evidence

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Recent studies have found a dipole pattern of hydroclimate variation in western Asia (WA) and arid central Asia (ACA) during the Holocene. However, speleothem δ18O evidence shows some inconsistencies with other lines of evidence, especially concerning the timing of peak wetness in WA and precipitation trends in ACA.
