Intercomparison of Daily Maximum and Minimum Temperature Gridded Products Over Mainland Spain

open access: yesInternational Journal of Climatology, Volume 45, Issue 14, 30 November 2025.
Extreme event of min. temperature occurred between January 26th and February 2nd 2005. Observational uncertainty is greater for minimum than for maximum temperatures, although it depends on the analysis dimension considered, so intercomparison analyses are needed.

Large‐scale atmospheric variability entails differential modes of seasonal tree growth in the Mediterranean Basin

open access: yesJournal of Ecology, Volume 113, Issue 9, Page 2652-2667, September 2025.
This work demonstrates the control of teleconnections on seasonal tree growth through local climate across the Mediterranean basin. Despite the constant link between the East Atlantic Pattern and temperature, synergies among teleconnections point to an east–west dipole in tree seasonal growth, driven by precipitation variability.

Assessing the Reliability of the Pseudo‐Thellier Estimates in Fired Ceramics and Source Clays

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.
Abstract The geomagnetic field's intensity is key to understanding the Earth's core dynamics and their surface impacts. While the Thellier–Thellier method remains the standard for recovering absolute paleointensity from baked materials, it is time‐consuming and may alter magnetic mineralogy due to heating cycles. The pseudo‐Thellier method offers a non‐

Not just semantics: CO2 fertilization can be a disturbance leading to worldwide forest degradation

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 3, Page 638-643, May 2025.
The physiological effects of increased atmospheric CO2 (CO2 fertilization) on intact forests are generally seen as a process that might buffer them against the impacts of climate change. However, CO2 fertilization can also cause adverse changes in forest conditions, such as alterations in species composition and reduced ecosystem moisture availability.

Early‐Stage Extratropical Cyclones' Mechanisms Over South America: RCM Added Value and Future Changes in a Warmer Planet

open access: yesInternational Journal of Climatology, Volume 45, Issue 1, January 2025.
The extratropical cyclogenesis in South America is projected to present weaker upper level forcing, in contrast to stronger low‐level mechanisms related to diabatic processes. These changes are related to the general decrease in the total number of cyclones in the region and an intensification of the systems in the future, respectively.
