Multitemporal Relationships Between the Hydroclimate and Exports of Carbon, Nitrogen, and Phosphorus in a Small Agricultural Watershed

Agriculture affects the biogeochemical cycles of carbon, nitrogen, and phosphorus, leading to a deterioration of surface water quality. The increasing magnitude of climate change raises questions about potential additional or mitigating effects of climate ...

The Legacy Effects of Winter Climate on Microbial Functioning After Snowmelt in a Subarctic Tundra

Konstantin Svetlozarov Gavazov

Warming-induced increases in microbial CO2 release in northern tundra may positively feedback to climate change. However, shifts in microbial extracellular enzyme activities (EEAs) may alter the impacts of warming over the longer term. We investigated the ...

Concerns of young protesters are justified

Philippe Thalmann, Dominique Bourg

In this letter, we recall that young people's concerns about climate change are based on our best scientific knowledge and that the measures taken so far by our authorities to protect the climate and the biosphere are far from up to the threat. We therefor ...

Magnitude of urban heat islands largely explained by climate and population

Gabriele Manoli, Gabriel George Katul, Paolo Burlando

Urban heat islands (UHIs) exacerbate the risk of heat-related mortality associated with global climate change. The intensity of UHIs varies with population size and mean annual precipitation, but a unifying explanation for this variation is lacking, and th ...

Understanding climate change from a global analysis of city analogues

Gabriele Manoli, Haozhi Ma

Combating climate change requires unified action across all sectors of society. However, this collective action is precluded by the ‘consensus gap’ between scientific knowledge and public opinion. Here, we test the extent to which the iconic cities around ...

Combined effects of pumped-storage operation and climate change on thermal structure and water quality

Alfred Johny Wüest, Martin Schmid, Ulrike Kobler

The assessment of ecological impacts of pumped-storage (PS) hydropower plants on the two connected water bodies is usually based on present climatic conditions. However, significant changes in climate must be expected during their long concession periods. ...

Optimized Design of Silicon Heterojunction Solar Cells for Field Operating Conditions

Christophe Ballif, Mathieu Gérard Boccard, Jan Haschke, Jean Cattin, Brahim Aissa, Olivier Denis Dupré

Solar modules are currently characterised at standard test conditions (STC), defined at 1000 W/m2 and 25 °C. However, solar modules in actual outdoor operating conditions typically operate at lower illumination and higher temperature than STC, which signif ...

Reliability of photovoltaic modules

Eleonora Annigoni

A fundamental challenge with solar energy is improving the reliability, and increasing the lifetime, of photovoltaic modules. Typically, photovoltaic module manufacturers guarantee 80% of the nominal power of their modules for 25 years, but this type of gu ...

Risk perception and decision-making: do farmers consider risks from climate change?

Claudia Rebeca Binder Signer

Small-scale farmers are highly threatened by climate change. Experts often base their interventions to support farmers to adapt to climate change on their own perception of farmers' livelihood risks. However, if differences in risk perception between farme ...

Silicon heterojunction solar cells: Recent technological development and practical aspects - from lab to industry

Christophe Ballif, Mathieu Gérard Boccard, Jan Haschke, Olivier Denis Dupré

We review the recent progress of silicon heterojunction (SHJ) solar cells. Recently, a new efficiency world record for silicon solar cells of 26.7% has been set by Kaneka Corp. using this technology. This was mainly achieved by remarkably increasing the fi ...
