Modeling energy supply with concentrating solar power

23 June 2014 - Concentrating solar power (CSP) could supply a substantial amount of current energy demand. C2SM member Anthony Patt and two colleagues from the Department of Environmental Systems Science significantly contributed to a study recently published in the journal Nature Climate Change. In the Mediterranean region, for example, the study shows that a connected CSP system could provide 70-80% of current electricity demand, at no extra cost compared to gas-fired power plants. That percentage is similar to what a standard energy production plant, such as a nuclear plant, can provide. In the new study, the researchers simulated the construction and operation of CSP systems, taking into account weather variations, plant locations, electricity demand, and costs.

Public lecture on "The Recent Global Warming Hiatus"

17 June 2014 - The “Latsis Symposium on Atmosphere and Climate Dynamics” takes place in Zurich this week. C2SM supports the meeting of leading scientists from around the world that discuss current questions from cloud microphysics to global circulation. On Friday evening, June 20, Dennis Hartmann (University of Washington) will give a public lecture on “The Recent Global Warming Hiatus: What Does It Mean for the Future?” The rapid rate of global warming since about 1980 has slowed down in the past decade or so, despite the fact that greenhouse gases continue to increase at an accelerated rate. The reasons for this slowdown in warming will be examined and their implications for the future of climate will be explored. The lecture at 18:00 is open to everyone at Auditorium Maximum, ETH Main Building. Admission is free.

"Klimarunde 2013" featured in the annual report of ETH

1 May 2014 - "ETH-Klimarunde" was prominently mentioned in the annual report 2013 of ETH. It states that "imparting knowledge and maintaining a dialogue with society, industry and politics is important to ETH Zurich." "ETH-Klimarunde" was one of the events in 2013 that offered scientists the opportunity to present their work for the UN climate report and discuss it with the public, the annual report says. Read the full report here. More information about "Klimarunde 2013". Register here for "Klimarunde 2014: Innovationen fürs Klima – Was braucht es, damit wir handeln können?"

Spatially explicit inventory of methane fluxes in Switzerland

23 April 2014 - Methane is an important greenhouse gas. Rebecca Hiller, C2SM members Nina Buchmann, Dominik Brunner and co-authors recently published the first high-resolution (500 m × 500 m) gridded methane (CH4) emission inventory for Switzerland. It integrates 90 % of the national emission totals reported to the United Nations Framework Convention on Climate Change (UNFCCC) and recent CH4 flux studies conducted by research groups across Switzerland. In addition to anthropogenic emissions, we also include natural and semi-natural CH4 fluxes, i.e., emissions from lakes and reservoirs, wetlands, wild animals as well as uptake by forest soils. In Switzerland, the highest CH4 emissions in 2011 originated from the agricultural sector (150 Gg CH4 yr−1) were mainly produced by ruminants and manure management. They were followed by emissions from waste management (15 Gg CH4 yr−1) mainly from landfills and the energy sector (12 Gg CH4 yr−1), which was dominated by emissions from natural gas distribution. Compared with the anthropogenic sources, emissions from natural and semi-natural sources were relatively small (6 Gg CH4 yr−1), making up only 3 % of the total emissions in Switzerland. This new inventory will provide valuable input for regional-scale atmospheric modeling and inverse source estimation.

C2SM contributes to Switzerland's national adaptation strategy

14 April 2014 - The Federal Council adopted its action plan 2014-2019 for climate change adaptation on April 9th. The plan is based on the Swiss Climate Scenarios CH2011 by C2SM and collaborators. It also makes use of recent extensions that are developed within the C2SM-coordinated CH2011+ initiative, such as temperature-based climate indices. Recognizing the large uncertainties still inherent in the prediction of climate change and climate change impacts, the action plan stresses the continuous development and updating of the relevant knowledge-base, such as the generation and dissemination of future climate scenarios. The associated activity is led by MeteoSwiss in collaboration with C2SM, several Federal Offices and the Cantons. Find the complete report here.

C2SM researchers contribute to IPCC reports on impacts, adaptation and mitigation

4 April 2014 - The Intergovernmental Panel on Climate Change (IPCC) has just released the Fifth Assessment Report of Working Group II, covering climate impacts and adaptation. The report on mitigation by Working Group III will follow later this month. C2SM members Andreas Fischlin and Anthony Patt have substantially contributed to the report of both Working Groups. Whereas the impacts have received a lot of attention in the international press, less is being said about the findings on adaptation strategies. Find the contribution of Anthony Patt on the ETH Zukunftsblog.

Major findings of the chapters on impacts and adaptation (WG II) and mitigation (WG III) will be presented by contributors and experts from Switzerland in Zurich (Stakeholder Anlass: Auswirkungen des Klimawandels und Klimapolitik - Ergebnisse des 5. IPCC-Berichts. April 16 2014) and in Fribourg (Forum IPCC: Fifth Assessment Reports AR5 on Impact, Adaptation, Vulnerability and Mitigation (WGII , WGIII)). More information on the reports can be found here for WG II Impacts and Adaptation and for WG III Mitigation.

Conference on High Performance Computing: session on climate and atmospheric modeling

21 March 2014 - On June 2-3, Platform for Advanced Scientific Computing (PASC) is hosting the PASC14 conference. The conference aims at bringing together scientists from diverse scientific domains to foster interdisciplinary collaborations and to strengthen high-performance computing knowledge exchange. As part of this conference, Christoph Schär and Isabelle Bey organize a session on climate and atmospheric modeling. Deadline for submission of abstracts for talks and posters: March 31, 2014.
