As climate change intensifies, extreme weather increasingly threatens California’s Central Valley (CV), a vital agricultural region exposed to rising risks from heatwaves (HW), droughts (DR), and compound extremes. These events disrupt crop productivity and broader processes like water demand, pest dynamics, and soil stability, posing systemic risks. This study examines the spatiotemporal dynamics of HW, coldwaves (CW), DR, excessive rainfall (ER), and their compound (e.g., HWDR) and cascading forms from 1951 to 2025, using NOAA nClimGrid-Daily data. We assessed trends in frequency, intensity, and duration over long-term (1951–2025) and mid-term (1981–2025) periods. Results show increasing HW and DR in the …

International Journal of Speleology
This study presents the results of a long-term investigation of the microclimatic conditions in Shulgan-Tash Cave (Southern Urals, Russia), which hosts the largest assemblage of Upper Paleolithic paintings (ca. 16.3–19.6 ka) in Eastern Europe. The cave exhibits two distinct seasonal ventilation regimes – winter and summer – differentially influence its two levels of galleries. In the Lower Level, which contains 83% of the images, near-atmospheric CO2 concentrations persist year-round, and temperature variations associated with seasonal infiltration events are minimal (1.0–1.3°C). By contrast, the Upper Level, including the decorated Hall of Paintings, is affected by downdrafts of CO2-rich …

Tillage Legacy, Grasses And Soil Texture Shape Soil Organic Carbon Recovery In Semi-Arid Woodland, Samantha Colunga, Alejandro Fierro-Cabo, Bradley O. Christoffersen, Engil Pereira

Soil degradation from intensive tillage poses a critical barrier to carbon sequestration, particularly in semi-arid regions where low rainfall limits ecosystem recovery. As climate change expands arid zones globally, understanding the long-term potential for soil organic carbon (SOC) recovery in degraded lands becomes increasingly urgent. Here, we analyze reforested chronosequences (4–36 years post-abandonment) in formerly cultivated subtropical thornscrub woodlands to assess SOC dynamics across gradients of soil texture and degradation. We introduce a novel degradation index (DI), integrating SOC deficit and grass dominance, to evaluate how invasive grasses, commonly overlooked in restoration metrics, impede nitrogen (N2)-fixing tree establishment and, consequently, …
