Mountain vegetation dries out Alpine water fluxes
Mountain vegetation dries out Alpine water fluxes
ETH researchers confirm the paradox: rather than withering during droughts, plants at higher elevations absolutely thrive, as a study just published Climate Change shows. Until now, scientists assumed that most plants suffer from water stress during droughts: they close their stomata to retain water, stop growing and, in the worst case, wither.

Climate change: how can we unleash citizen action?
Climate change: how can we unleash citizen action?
A researcher from the University of Geneva has synthesized two decades of scientific studies on climate change to identify the obstacles to behaviour change and find ways to overcome them. Why is it that more individual actions are not taken to combat climate change? What should be done to embolden individuals to act within their scope of action? To answer these questions, a researcher at the University of Geneva , Switzerland, integrated the results of the scientific literature on climate change in the framework of a Geneva Science-Policy Interface (GSPI) policy brief.

"Green economy": an ambiguous concept that is on the way out
Concerns about climate change have given rise to a whole series of concepts that are widely used despite their lack of a concrete definition. EPFL researchers have taken a closer look at the "green economy" concept in particular to clarify exactly what it means. Today's consumers want a cleaner, greener society.

The salt of the comet
The salt of the comet
Under the leadership of astrophysicist Kathrin Altwegg, Bernese researchers have found an explanation for why very little nitrogen could previously be accounted for in the nebulous covering of comets: the building block for life predominantly occurs in the form of ammonium salts, the occurrence of which could not previously be measured.

Predicting hydraulic fracture propagation more accurately
Predicting hydraulic fracture propagation more accurately
Researchers at EPFL have developed a new model to calculate hydraulic fracture propagation. Acclaimed for its accuracy by experts, the model better predicts fracture geometry and the energy cost of hydraulic fracturing - a widely used technique in areas such as CO2 storage, hydrocarbon extraction, dams and volcano hazard monitoring.

Irrigation alleviates hot extremes
Irrigation alleviates hot extremes
Researchers from ETH Zurich and other universities found evidence that expanding irrigation has dampened anthropogenic warming during hot days, with particularly strong effects over South Asia. Large-scale irrigation is one of the land management practices with the largest effect on climate conditions - and especially hot extremes - in various regions across the globe.

Water governance: could less sometimes be more?
Water governance: could less sometimes be more?
Researchers from UNIGE and UNIL analysed water governance in six European countries from 1750 onwards. They demonstrated that there has been an inflationary trend in the number of regulations, and that - far from improving the situation - this has led to serious malfunctions in the system. The use of environmental resources has been regulated for centuries with the aim of improving the management and behaviour of private and public actors on an on-going basis.

Improved Functioning of Diverse Landscape Mosaics
Improved Functioning of Diverse Landscape Mosaics
It is well-established that biodiverse ecosystems generally function better than monocultures. Ecologists at the University of Zurich have now shown that the same is true on a larger scale: Having a mix of different land-covers including grassland, forest, urban areas and water bodies improves the functioning and stability of a landscape - irrespective of the plant species diversity, region and climate.

Reducing human-induced earthquake risk
Reducing human-induced earthquake risk
Researchers at EPFL and the Swiss Federal Office of Energy have devised strategies for reducing the earthquake risk associated with geothermal energy, CO2 storage and other human activities happening deep underground. Although most earthquakes are attributable to natural causes, some are triggered - directly or indirectly - by human activity.

Fingerprint of climate change detected in daily weather
Fingerprint of climate change detected in daily weather
Climate researchers can now detect the fingerprint of global warming in daily weather observations at the global level. They are thus amending a long-established paradigm: weather is not climate ' but climate change can now be detected in daily weather. This research was carried out by ETH Zurich and the Swiss Data Science Center, co-directed by EPFL.

Climate signals detected in global weather
Climate signals detected in global weather
Searched for and found: climate researchers can now detect the fingerprint of global warming in daily weather observations at the global scale. They are thus amending a long-established paradigm: weather is not climate - but climate change can now be detected in daily weather. In October this year, weather researchers in Utah measured the lowest temperature ever recorded in the month of October in the US (excluding Alaska): -37.1C.
