Rapidly increasing chance of record UK summer temperatures

open access: yesWeather, Volume 80, Issue 8, Page 268-276, August 2025.
The UK recorded its first exceedance of 40°C in July 2022. To assess the current chance of recurrence, we use a large climate model ensemble approach and find the 2023 return period to be 1‐in‐24 years (1/20–1/29 years confidence interval). However, the likelihood of 40°C has been accelerating and we estimate a 50–50 chance of another exceedance in the

Aspects of forest biomass in the earth system: Its role and major unknowns

open access: yes, 2019
Forests are a major and diverse land cover occupying a third of the terrestrial vegetated surface; they store 50 to 65% of terrestrial organic carbon (including the soil) and contribute half to terrestrial productivity. Forest biomass stores close to 80%

Interpreting Ice Anisotropy of Greenland's Fastest Outlet Glacier Using Basal Icequakes

open access: yesGeophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract Ice anisotropy can have significant impact on ice rheology and flow dynamics. However, a lack of in situ measurements limits the validation and incorporation of anisotropy, so most ice flow models assume isotropic ice. Especially observations of anisotropy in fast‐flowing ice streams are scarce.

Viewing Stomata in Action: Autonomous in Planta Imaging of Individual Stomatal Movement

open access: yesPlant, Cell &Environment, Volume 48, Issue 6, Page 4533-4549, June 2025.
ABSTRACT Stomata regulate plant gas exchange under changing environments, but observations of single stomata dynamics in planta are sparse. We developed a compact microscope system that can measure the kinetics of tens of stomata in planta simultaneously, with sub‐minute time resolution.

Photonic crystal-driven spectral concentration for upconversion photovoltaics [PDF]

open access: yes, 2015
International audienceThe main challenge for applying upconversion (UC) to silicon photovoltaics is the limited amount of solar energy harvested directly via erbium-based upconverter materials (24.5 W m(-2)).

Chinese Development Finance and African Policy Space: Towards Productive Incoherence?

open access: yesJournal of International Development, Volume 37, Issue 4, Page 1039-1053, May 2025.
ABSTRACT How does Chinese Development Finance influence perceptions of policy space across Sub‐Saharan Africa? This paper employs Grabel's concept of ‘productive incoherence’ to both describe the ‘new development finance landscape’ and to explore its implications for recipient‐country policy space.

Analysis of frequency and intensity of European winter storm events from a multi-model perspective, at synoptic and regional scales [PDF]

open access: yes, 2006
This study focuses on the analysis of winter (October-November-December-January-February-March; ONDJFM) storm events and their changes due to increased anthropogenic greenhouse gas concentrations over Europe. In order to assess uncertainties that are due

Improved Real‐Time Hail Damage Estimates Leveraging Dense Crowdsourced Observations

open access: yesMeteorological Applications, Volume 32, Issue 3, May/June 2025.
This study leverages dense crowdsourced hail reports over Switzerland to improve real‐time building damage predictions. By applying a rigorous filtering approach and a custom interpolation method, a gridded hail size product is derived for each event and used as input to a hail damage model.
