    Diverging importance of drought stress for maize and winter wheat in Europe
    ([London] : Nature Publishing Group UK, 2018) Webber, Heidi; Ewert, Frank; Olesen, Jørgen E.; Müller, Christoph; Fronzek, Stefan; Ruane, Alex C.; Bourgault, Maryse; Martre, Pierre; Ababaei, Behnam; Bindi, Marco; Ferrise, Roberto; Finger, Robert; Fodor, Nándor; Gabaldón-Leal, Clara; Gaiser, Thomas; Jabloun, Mohamed; Kersebaum, Kurt-Christian; Lizaso, Jon I.; Lorite, Ignacio J.; Manceau, Loic; Moriondo, Marco; Nendel, Claas; Rodríguez, Alfredo; Ruiz-Ramos, Margarita; Semenov, Mikhail A.; Siebert, Stefan; Stella, Tommaso; Stratonovitch, Pierre; Trombi, Giacomo; Wallach, Daniel
    Understanding the drivers of yield levels under climate change is required to support adaptation planning and respond to changing production risks. This study uses an ensemble of crop models applied on a spatial grid to quantify the contributions of various climatic drivers to past yield variability in grain maize and winter wheat of European cropping systems (1984–2009) and drivers of climate change impacts to 2050. Results reveal that for the current genotypes and mix of irrigated and rainfed production, climate change would lead to yield losses for grain maize and gains for winter wheat. Across Europe, on average heat stress does not increase for either crop in rainfed systems, while drought stress intensifies for maize only. In low-yielding years, drought stress persists as the main driver of losses for both crops, with elevated CO2 offering no yield benefit in these years.

    Europe’s renewable energy directive poised to harm global forests
    ([London] : Nature Publishing Group UK, 2018) Searchinger, Timothy D.; Beringer, Tim; Holtsmark, Bjart; Kammen, Daniel M.; Lambin, Eric F.; Lucht, Wolfgang; Raven, Peter; van Ypersele, Jean-Pascal
    This comment raises concerns regarding the way in which a new European directive, aimed at reaching higher renewable energy targets, treats wood harvested directly for bioenergy use as a carbon-free fuel. The result could consume quantities of wood equal to all Europe’s wood harvests, greatly increase carbon in the air for decades, and set a dangerous global example.

    Climate mobilities, rights and justice: Complexities and particularities
    (Lausanne : Frontiers Media, 2022) Farbotko, Carol; Thornton, Fanny; Mayrhofer, Monika; Hermann, Elfriede
    Climate mobility revolves around issues of justice and human rights, whether this be concerning its causes, expression or handling. This paper examines the justice-rights nexus as it relates to climate mobility, highlighting how the two spheres converge and diverge. It works with four case studies exploring the complexity of rights and justice in the climate mobility context. Our case studies are diverse, in terms of the mobility types concerned and the rights and justice-based issues involved. We show that conceptualizing or achieving just or righteous outcomes is neither certain nor a uniform pursuit when it comes to climate mobility. Rather, there are many divergences–by those who claim rights or justice, and those asked to respond. We present a complex and contested space, highlight the importance of approaching justice and rights matters contextually, and with special attention to particularities when climate mobility is at issue.

    The future is now: Climate displacement and human rights obligations—a note on recent developments in the UN Human Rights Committee
    (Lausanne : Frontiers Media, 2022) Thornton, Fanny
    Although climate litigation—or the pursuit of legal resolve of matters stemming from anthropogenic climate change—has been growing around the world, climate mobility is seldom at the heart of relevant case law. It is human rights law bodies, in particular, which have nevertheless begun to progress legal developments in the sphere of climate mobility. This note looks at a 2022 determination by the UN Human Rights Committee concerning the habitability of a small island setting—Australia's Torres Strait Islands—under climate change conditions and the legal responsibilities of nation states to abide by their international human rights obligations in implementing timely adaptation measures now which could help to ensure continued habitation.
