Atmospheric isoprene measurements reveal larger-than-expected Southern Ocean emissions

Isoprene is a key trace component of the atmosphere emitted by vegetation and other organisms. It is highly reactive and can impact atmospheric composition and climate by affecting the greenhouse gases ozone and methane and secondary organic aerosol format ...

Elucidating the present-day chemical composition, seasonality and source regions of climate-relevant aerosols across the Arctic land surface

Julia Schmale, Imad El Haddad

The Arctic is warming two to three times faster than the global average, and the role of aerosols is not well constrained. Aerosol number concentrations can be very low in remote environments, rendering local cloud radiative properties highly sensitive to ...

Modeling Extreme Warm-Air Advection in the Arctic During Summer: The Effect of Mid-Latitude Pollution Inflow on Cloud Properties

Georgia Sotiropoulou

Usually the Arctic is relatively free of anthropogenic influence in summer, which means that particles from natural sources can be the most significant nuclei for cloud droplets. However, this is not the case during anomalously warm-air intrusions when the ...

Photic stress on coral reefs in the Maldives: The Amphistegina bleaching index

Arthur Adams, Aurélie Angéloz, Anaël Lehmann

The Amphistegina Bleaching Index (ABI) was applied to three Maldivian reefs in the Rasdhoo and North Ari Atolls in 2018, during normal sea surface temperature conditions. This dataset was then compared with a 2015, pre-coral bleaching study. The results pr ...

Seascape genomics as a new tool to empower coral reef conservation strategies: an example on north‐western Pacific Acropora digitifera

Stéphane Joost, Oliver Michele Selmoni, Estelle Rochat

Coral reefs are suffering a major decline due to the environmental constraints imposed by climate change. Over the last 20 years, three major coral bleaching events occurred in concomitance with anomalous heatwaves, provoking a severe loss of coral cover w ...

Stream temperature and discharge evolution in Switzerland over the last 50 years: annual and seasonal behaviour

Michael Lehning, Wolf Hendrik Huwald, Adrien Michel, Bettina Schaefli, Tristan Jonas Brauchli

Stream temperature and discharge are key hydro- logical variables for ecosystem and water resource management and are particularly sensitive to climate warming. Despite the wealth of meteorological and hydrological data, few studies have quantified observe ...

Investigating the importance of future climate typology on estimating the energy performance of buildings in the EPFL campus

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Silvia Coccolo, Vahid Moussavi Nik

Climate changes induce warmer climate with stronger and more frequent extreme events. Due to the uncertain nature of climate, accurate simulation of future conditions is impossible and a major challenge is the selection of climate data in the impact assess ...

An analysis of the July 2006 heatwave extent in Europe compared to the record year of 2003

Martine Rebetez

Recent analyses have identified summer warming trends in Europe in recent decades, culminating in 2003, when mean summer temperatures were exceptionally hot over much of Europe. Mean monthly temperatures were very high in July 2003 and reached record level ...

Evaporation from three water bodies of diﬀerent sizes and climates: Measurements and scaling analysis

Marc Parlange, Shirit Cohen, Gabriel George Katul, Scott W. Tyler

Evaporation from small reservoirs, wetlands, and lakes continues to be a theoretical and practical problem in surface hydrology and micrometeorology because atmospheric ﬂows above such systems can rarely be approximated as stationary and planar-homogeneous ...
